Quando si lavora con database e sistemi informatici, le date sono uno degli aspetti fondamentali da gestire con attenzione. Tuttavia, potresti imbatterti in una strana situazione: l’uso di una data come “0000-00-00”, che apparentemente potrebbe sembrare una data valida, ma in realtà non esiste né nel calendario gregoriano tradizionale né nei sistemi moderni come MySQL. In questo articolo esploreremo perché l’anno “0000” non esiste, come viene gestito nei sistemi informatici e quali sono le migliori pratiche per gestire correttamente le date nei database, in particolare in MySQL. Sommario Il calendario gregoriano, l’anno zero e le date informatiche MySQL e la gestione delle date “0000-00-00” Modalità SQL Mode di MySQL e le restrizioni sulle date Perché è importante evitare l’uso di “0000-00-00” Limitazioni del tipo TIMESTAMP in MySQL Migliori pratiche per gestire le date in MySQL Conclusione Approfondimenti Il calendario gregoriano, l'anno zero e le date informatiche Nel calendario gregoriano, non esiste l’anno zero, creando incompatibilità con alcune date nei database MySQL. Il calendario gregoriano, introdotto nel 1582 e utilizzato nella maggior parte dei sistemi informatici, inizia ufficialmente il 1º gennaio dell’anno 0001 (ovvero, 0001-01-01). Nel calendario gregoriano tradizionale non esiste l'anno zero; si passa direttamente dall'1 a.C. all'1 d.C. Questo significa che l’anno “0000” non è considerato valido nel calendario gregoriano classico. Tuttavia, alcuni sistemi e standard internazionali, come l'ISO 8601, utilizzano l'anno zero per semplificare i calcoli e la rappresentazione delle date storiche. In questo contesto, l'anno zero corrisponde all'1 a.C., permettendo una sequenza continua di anni che facilita operazioni matematiche e computazionali sulle date. Il calendario gregoriano prolettico Per gestire date precedenti all'introduzione del calendario gregoriano nel 1582, alcuni sistemi adottano il calendario gregoriano prolettico. Questo estende il calendario gregoriano a ritroso nel tempo, includendo date storiche antecedenti. Anche in questo caso, l'anno zero può essere utilizzato per uniformare i calcoli, sebbene nel calendario gregoriano tradizionale non sia previsto. MySQL e la gestione delle date “0000-00-00” In MySQL, la data '0000-00-00' viene segnalata come non valida, causando errori se non gestita correttamente. Nei database MySQL, le colonne di tipo DATE vengono utilizzate per memorizzare le date. MySQL supporta date comprese tra '1000-01-01' e '9999-12-31'. Questo significa che date come '0001-01-01' o qualsiasi data precedente all'anno 1000 non sono considerate valide in MySQL. Tentare di inserire tali date genererà un errore o restituirà '0000-00-00' come valore predefinito. In alcune versioni precedenti di MySQL, era possibile inserire una data come “0000-00-00”. Questo formato, pur non essendo una data reale, veniva accettato da MySQL come valore di placeholder per indicare che una data non era stata ancora definita o era sconosciuta. Tuttavia, questo comportamento può causare diversi problemi, soprattutto quando si cercano di eseguire confronti, query o analisi su dati che contengono queste date “zero”. Esempio pratico Supponiamo di avere una tabella eventi con una colonna data_evento di tipo DATE. Se tentiamo di inserire una data non valida: INSERT INTO eventi (nome_evento, data_evento) VALUES ('Evento Storico', '0000-00-00'); In MySQL 5.6 o versioni precedenti senza modalità restrittive, questo inserimento potrebbe essere accettato, impostando data_evento a '0000-00-00'. Tuttavia, in MySQL 5.7 e versioni successive con modalità SQL restrittive attivate, come di default, questo inserimento genererà un errore. Modalità SQL Mode di MySQL e le restrizioni sulle date Le impostazioni NO_ZERO_IN_DATE e NO_ZERO_DATE in MySQL bloccano l’inserimento di date non valide come 0000-00-00. Con l’introduzione di MySQL 5.7 e, in particolare, nella versione 8.

0, la configurazione SQL Mode predefinita include modalità che aiutano a evitare l’uso di date non valide come “0000-00-00”. Tra queste, ci sono due restrizioni importanti: NO_ZERO_IN_DATE: questa modalità impedisce l’inserimento di date che hanno parti zero, come “2024-00-15” o “0000-12-01”. Non è possibile inserire una data con il mese o il giorno impostati su zero. NO_ZERO_DATE: questa modalità è cruciale per evitare l’inserimento di date come “0000-00-00”. Se tenti di inserire una data di questo tipo in una colonna DATE o DATETIME, MySQL restituirà un errore. Grazie a queste modalità, MySQL garantisce che vengano inserite solo date valide secondo il calendario gregoriano, migliorando l’integrità dei dati e prevenendo errori logici nelle applicazioni. Chiarimenti sulle versioni di MySQL È importante notare che il comportamento riguardante le date zero può variare tra le diverse versioni di MySQL: MySQL 5.6 e precedenti: le date zero possono essere inserite se le modalità SQL restrittive non sono attivate. MySQL 5.7 e successive: le modalità NO_ZERO_IN_DATE e NO_ZERO_DATE sono attive per impostazione predefinita, impedendo l'inserimento di date non valide, ma è possibile disattivarle. Per assicurarti di gestire correttamente le date nel tuo database, verifica sempre la versione di MySQL in uso e le modalità SQL attive. Perché è importante evitare l’uso di “0000-00-00” Utilizzare '0000-00-00' in MySQL può provocare incoerenze nelle query, limitazioni di compatibilità e difficoltà nell'analisi dei dati. L’utilizzo di “0000-00-00” come data predefinita può causare numerosi problemi nei sistemi software e nelle applicazioni: Incoerenze nelle query: le query che confrontano le date possono produrre risultati inattesi o errati se si includono date come “0000-00-00”. Ad esempio, un semplice confronto tra date può fallire o restituire risultati imprevedibili se non si tiene conto delle date non valide. Compatibilità con altri sistemi: molti linguaggi di programmazione e sistemi di reportistica non gestiscono correttamente date invalide, come “0000-00-00”. Questo può portare a crash dell’applicazione, errori di parsing o dati corrotti. Difficoltà nell’analisi dei dati: strumenti di analisi o di business intelligence potrebbero interpretare erroneamente “0000-00-00” come una data valida, influenzando negativamente la precisione dei report e delle analisi. Limitazioni del tipo TIMESTAMP in MySQL Il tipo TIMESTAMP in MySQL gestisce solo date tra il 1970 e il 2038, limitando l’uso di date storiche o future. Oltre alle considerazioni già fatte sulle date non valide, è importante comprendere come il tipo di dato TIMESTAMP in MySQL gestisce le date, specialmente quelle precedenti all'anno 1970. Il problema delle date prima del 1970 Il tipo di dato TIMESTAMP memorizza l'istante temporale come il numero di secondi trascorsi dal 1º gennaio 1970 alle 00:00:00 UTC, noto come Epoch Unix. A causa di questa rappresentazione: Intervallo limitato: TIMESTAMP può rappresentare date e orari compresi tra '1970-01-01 00:00:01' UTC e '2038-01-19 03:14:07' UTC. Impossibilità di inserire date precedenti al 1970: non è possibile inserire date precedenti al 1º gennaio 1970 utilizzando il tipo TIMESTAMP. Tentativi di farlo restituiranno un valore nullo o genereranno un errore, a seconda delle impostazioni del server. Esempio pratico Supponiamo di avere una tabella eventi con una colonna data_evento di tipo TIMESTAMP: CREATE TABLE eventi ( id INT AUTO_INCREMENT PRIMARY KEY, nome_evento VARCHAR(255), data_evento TIMESTAMP ); Se tentiamo di inserire una data precedente al 1970: INSERT INTO eventi (nome_evento, data_evento) VALUES ('Evento Storico', '1969-12-31 23:59:59'); Questo inserimento fallirà o data_evento verrà impostato al valore predefinito '1970-01-01 00:00:00', poiché il tipo TIMESTAMP non può rappresentare date precedenti all'Epoch Unix. Soluzione: utilizzare DATE o DATETIME

Se hai bisogno di memorizzare date precedenti al 1970, dovresti utilizzare i tipi di dato DATE o DATETIME, che supportano un intervallo più ampio: DATE: Intervallo: da '1000-01-01' a '9999-12-31'. Uso: memorizza solo la parte di data (anno, mese, giorno). DATETIME: Intervallo: da '1000-01-01 00:00:00' a '9999-12-31 23:59:59'. Uso: memorizza sia la data che l'ora. Riformulando la tabella eventi utilizzando DATETIME: CREATE TABLE eventi ( id INT AUTO_INCREMENT PRIMARY KEY, nome_evento VARCHAR(255), data_evento DATETIME ); Ora, l'inserimento della data precedente al 1970 avverrà correttamente: INSERT INTO eventi (nome_evento, data_evento) VALUES ('Evento Storico', '1969-12-31 23:59:59'); Perché scegliere TIMESTAMP o DATETIME TIMESTAMP: Utile per tracciare l'ora corrente o per registrare automaticamente il momento di creazione o aggiornamento di una riga. Tiene conto del fuso orario del server o della connessione. DATETIME: Ideale per memorizzare date e orari specifici che non devono essere influenzati dai fusi orari. Supporta un intervallo di date molto più ampio, incluse date storiche. Raccomandazioni Evita TIMESTAMP per date storiche: se devi gestire date precedenti al 1970 o future oltre il 2038, utilizza DATE o DATETIME. Scegli il tipo di dato appropriato: valuta le esigenze della tua applicazione per decidere se utilizzare TIMESTAMP, DATE o DATETIME. Migliori pratiche per gestire le date in MySQL Per gestire correttamente le date in MySQL, usa NULL per date sconosciute, attiva Strict Mode e valida le date nell’applicazione. Ecco alcuni consigli per evitare i problemi legati a date invalide come “0000-00-00”: Utilizza il valore NULL per le date non definite: invece di inserire una data invalida come “0000-00-00” quando non conosci una data, è buona norma usare NULL. Questo indica chiaramente che la data non è stata ancora impostata o non è applicabile. INSERT INTO eventi (nome_evento, data_evento) VALUES ('Evento Futuro', NULL); Attiva Strict Mode e mantieni le restrizioni sulle date: la modalità Strict Mode in MySQL e le restrizioni NO_ZERO_IN_DATE e NO_ZERO_DATE dovrebbero essere mantenute attive, poiché impediscono l’inserimento di dati non validi. Queste modalità rendono il database più robusto e aiutano a prevenire errori futuri. SET sql_mode = 'STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE'; Valore default di sql_mode: in MySQL 8.0 il valore predefinito è il seguente: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION Valida le date a livello di applicazione: aggiungi logica di validazione nella tua applicazione per assicurarti che gli utenti inseriscano solo date valide. Ciò riduce la possibilità che valori non validi vengano inviati al database. In PHP: if (DateTime::createFromFormat('Y-m-d', $data_input) !== false) // La data è valida else // Gestisci l'errore In JavaScript: if (!isNaN(Date.parse(dataInput))) // La data è valida else // Gestisci l'errore Gestisci le date storiche con attenzione: se devi gestire date storiche precedenti all'anno 1000 o utilizzare l'anno zero, considera l'uso di tipi di dati alternativi o di estensioni specifiche che supportano queste esigenze. In alcuni casi, potrebbe essere opportuno utilizzare colonne di tipo VARCHAR e implementare una logica personalizzata per la validazione e il confronto delle date. Conclusione L’uso di date non valide come “0000-00-00” è una pratica che può causare una serie di problemi nei database e nelle applicazioni. Grazie alle restrizioni introdotte nelle versioni più recenti di MySQL, come NO_ZERO_DATE e NO_ZERO_IN_DATE, è possibile evitare questi errori e mantenere l’integrità dei dati. La gestione corretta delle date, inclusa l’adozione del valore NULL quando una data non è disponibile, è essenziale per garantire che il database e le applicazioni funzionino senza problemi.

Inoltre, essere consapevoli delle limitazioni del calendario gregoriano tradizionale e delle sue estensioni nei sistemi informatici ti aiuterà a gestire meglio le date storiche o non standard. Seguendo queste pratiche, puoi evitare problemi di compatibilità e garantire che il tuo sistema gestisca correttamente le date, migliorando così la qualità del software che sviluppi.

MySQL 5.7 End-of-Life: What WooCommerce Store Owners Need to Know

MySQL 5.7 End-of-Life is fast approaching. Find out what you need to do as a WooCommerce store owner.

What is MySQL?

MySQL is the database management system responsible for storing and managing the vast amounts of data that WordPress processes. So it is worth noting that the version most widely used right now (MySQL 5.7), is approaching its end-of-life in October 2023. We recommend upgrading the current stable version which is MySQL 8.0 which also introduces features and key improvements to meet modern database requirements and security standards.

What Does This Mean for WooCommerce Store Owners?

For WooCommerce Store owners, the impending end-of-life for MySQL 5.7 has significant implications as this version will no longer receive updates or security patches beyond its end-of-life date. Continuing to use it poses potential risks to website security and performance. Most hosting service providers are also set to upgrade their servers within the near future. This can introduce compatibility issues leading to the disruption of regular website functions.

What You Can Do?

To avoid website functionality from being disrupted, WooCommerce store owners must take steps to ensure that the upgrade proceeds smoothly. It is ideal to test your current websites under a MySQL 8.0 environment to check for and fix any issues found. In our own tests, some websites encountered issues stemming from conflicts within plugins, themes or custom code while a few did not have any issues at all.

Please contact your hosting if they provide any means to be able to perform this testing. Here’s how to do this in WPEngine.

Enlisting the assistance of experienced developers will make this entire process easier. You may contact us here if you’d like us to look into this for you.

As the end-of-life for MySQL 5.7 approaches, WooCommerce store owners must act to ensure a seamless transition process. And by upgrading to the latest version of MySQL, website owners can take advantage of new features, improved performance, and enhanced security for their websites.

Please remember to perform backups and follow industry best practices in your testing. If you have any further questions, let us know here.

Amazon RDS Extended Support for MySQL 5.7 & PostgreSQL 11

Your MySQL 5.7 and PostgreSQL 11 database instances on Amazon Aurora and Amazon RDS will automatically enroll in Amazon RDS Extended Support commencing February 29, 2024.

This will prevent unanticipated downtime and compatibility concerns from automated major version upgrades. You have more control over when to upgrade your major database.

RDS Extended Support may cost more due to automated enrollment. Upgrade your database before RDS Extended Support to prevent these expenses.

Describe Amazon RDS Extended Support

Amazon RDS Extended Support, announced in September 2023, lets you run your database on a major engine version on Amazon Aurora or Amazon RDS after its end of standard support date for a fee.

The MySQL and PostgreSQL open source communities identify CVEs, generate patches, and resolve bugs until community end of life (EoL). Until the database major version is retired, the communities release a quarterly minor version with security and bug updates. CVE patches and bug fixes are no longer available after the community end of life date, making such engines unsupported. As of October and November 2023, the communities no longer support MySQL 5.7 and PostgreSQL 11. AWS appreciate community support of these major versions and a transparent transition process and schedule to the latest major version.

Amazon Aurora and RDS engineer crucial CVE patches and bug fixes for up to three years after a major version’s community EoL with RDS Extended Support. Amazon Aurora and RDS will find engine CVEs and problems, develop patches, and deploy them swiftly for three years. Under RDS Extended Support, AWS will continue to support an engine’s major version after the open source community ends support, protecting your applications from severe security risks and unresolved problems.

You may ask why we charge for RDS Extended Support instead of including it in RDS. AWS must invest developer resources in crucial CVE patches and bug fixes to preserve community EoL engine security and functionality. Because of this, RDS Extended Support only charges clients that need the flexibility to stay on a version past its EoL.

If your applications depend on a specific MySQL or PostgreSQL major version for plug-in compatibility or bespoke functionality, RDS Extended Support may help you satisfy your business objectives. If you’re running on-premises database servers or self-managed Amazon Elastic Compute Cloud (Amazon EC2) instances, you can migrate to Amazon Aurora MySQL-Compatible Edition, Amazon Aurora PostgreSQL-Compatible Edition, Amazon RDS for MySQL, and Amazon RDS for PostgreSQL beyond the community EoL date and use them with RDS Extended Support in a managed service. RDS Extended Support lets you phase a large database transfer to ensure a smooth transition without straining IT resources.

RDS Extended Support will be provided in 2024 for RDS for MySQL 5.7, PostgreSQL 11, Aurora MySQL-compatible 2, and Aurora PostgreSQL 11. A supported MySQL major version on Amazon RDS and Amazon Aurora major versions in the AWS documentation lists all future supported versions.

Why are all databases automatically enrolled in Amazon RDS Extended Support?

AWS were told you RDS Extended Support would deliver opt-in APIs and console functionality in December 2023. AWS announced that if you did not opt your database into RDS Extended Support, it would automatically update to a newer engine version on March 1, 2024. You would be upgraded from Aurora MySQL 2 or RDS for MySQL 5.7 to Aurora MySQL 3 or RDS for MySQL 8.0, and from Aurora PostgreSQL 11 to 15 and RDS for 15.

However, several users complained that these automated upgrades may damage their applications and cause other unpredictable behavior between major community DB engine releases. If applications are not ready for MySQL 8.0 or PostgreSQL 15, an unplanned major version upgrade could cause compatibility issues or downtime.

Automatic enrollment in RDS Extended Support allows you more time and control to organize, schedule, and test database upgrades on your own timeline while receiving essential security and bug fixes from AWS.

Upgrade before RDS standard support ends to prevent automatic enrollment in RDS Extended Support and associated fees.

Upgrade your database to avoid RDS Extended Support fees

RDS Extended Support helps you schedule your upgrade, but staying with previous versions means missing out on the greatest price-performance for your database workload and paying more for support.

Global Database, Amazon RDS Proxy, Performance Insights, Parallel Query, and Serverless v2 deployments are supported in Aurora MySQL 8.0, also known as Aurora MySQL 3. RDS for MySQL 8.0 supports AWS Graviton2 and Graviton3-based instances, Multi-AZ cluster deployments, and Optimized Reads and Writes for up to three times better performance than MySQL 5.7.

Aurora PostgreSQL 15 Aurora I/O Optimized, Aurora Serverless v2, Babelfish for Aurora PostgreSQL, pgvector extension, TLE, AWS Graviton3-based instances, and community additions are supported by PostgreSQL. RDS for PostgreSQL 15 adds Multi-AZ DB cluster deployments, RDS Optimized Reads, HypoPG extension, pgvector extension, TLEs, and AWS Graviton3-based instances.

Major version upgrades may change databases incompatible with existing apps. To upgrade to the major version, manually edit your database. Any major version upgrade should be tested on non-production instances before being applied to production to verify application compatibility. The AWS documentation describes an in-place upgrade from MySQL 5.7 to 8.0, including incompatibilities, Aurora MySQL in-place major version upgrade, and RDS for MySQL upgrades. Use pgupgrade to upgrade PostgreSQL 11 to 15 in-places.

AWS advocate Fully Managed Blue/Green Deployments in Amazon Aurora and Amazon RDS to reduce upgrade downtime. Amazon RDS Blue/Green Deployments can establish a synchronized, fully controlled staging environment that mimics production in a few clicks. A parallel green environment with upper-version clones of your production databases lower-version is needed. Traffic might transition to the green environment after validation. Blue environment can be discontinued. Blue/Green Deployments reduce downtime best in most cases, except with Amazon Aurora and Amazon RDS.

Currently accessible

Amazon RDS Extended Support is now available for clients utilizing MySQL 5.7, PostgreSQL 11, and higher versions in AWS Regions, including AWS GovCloud (US), beyond the 2024 standard support expiration. You can upgrade your databases and obtain 3 years of RDS Extended Support without opting in.
