Merge Two Table Using MySQLi in PHP

In this tutorial, we will create a Merge Two Table using MySQLi. This code will merge the two existing tables in the MySQLi server when the user clicks the merge button. The system uses a MySQLi SELECT() function and adds a LEFT JOIN parameter to merge the two existing tables into one that has the same key in both. This is a user-friendly kind of program feel free to the user in your application. We will be using PHP as a scripting language that manages a database server to handle a bulk of data per transaction. It describes as an advanced technology that manages both server and control-block of your machine. Getting Started: First, you have to download & install XAMPP or any local server that runs PHP scripts. Here's the link for the XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/. Creating Database Open your database web server, then create a database name in it db_merge; after that, click Import, then locate the database file inside the folder of the application then click ok. Creating the database connection Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php. Creating The Interface This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php. #createmultipletablesmysqlusingphp #crossjoinoracle #fullinnerjoin #fullouterjoinmysql #howcanijointwotablesinmysql #howcanijointwotablesinphp #howcanimergetwotablesindatabase #howmergeworksinmysql #howtofetchdatafromthreetablesinmysqlusingphp #howtofetchdatafromtwotablesinmysqlusingphp #howtofetchdatafromtwotablesinmysqlwithoutjoin #howtofetchdatafromtwotablesinmysqliusingphp #howtofetchdatafromtwotablesinsqlwithjoin #howtojoin4tablesinsqlquery #howtojointhreetablesinmysqlinphp #howtojointhreetablesinsqlusingjoins #howtojointwotableinphp #howtojointwotablesinmysql #howtojointwotablesinmysqlquery #howtojointwotablesinmysqlusingphpwithexample #howtojointwotablesinmysqlwithwhereclause #howtojointwotablesinphpmyadmin #howtolinktablesinmysql #howtolinktwotablesinmysql #howtomergetwotablesinsql #howtoretrievedatafrom4tablesinsql #howtoretrievedatafrommultipletablesinmysql #howtoretrievedatafrommultipletablesinsql #howtosearchdatafrommultipletableinmysql #howtosearchdatafrommultipletableinmysqlusingphp #howtoselectdatafromtwotablesinmysqlphp #innerjoin #innerjoin3tables #innerjoinmysql #join #joininphpmysql #joinonmultiplecolumnssql #jointablesfromdifferentdatabasesmysql #joiningmultipletablesusingmysql #leftinnerjoin #leftjoin #leftjoinmysql #leftjoinonmultiplecolumns #mariadbmergetwotables #mergeleftsql #mergemysql #mergetwodatabasetablesmysql #mergetwotableusingmysqlinphp #multipleleftjoinssql #mysqlcombinemultipletablesintoone #mysqlcombinetwoqueries #mysqlcombinetwotables #mysqlcomparetwotablesandmerge #mysqlcomparetwotablesfromdifferentdatabases #mysqlconcattwocolumnsfromdifferenttables #mysqlcreaterelationshipbetweentwotables #mysqlcrossjoin #mysqlfullouterjoin #mysqlgetdatafromtwotables #mysqlinnerjoin #mysqlinnerjoin3tables #mysqljoin #mysqljoin2tables #mysqljoincolumnsfrommultipletables #mysqljoinexample #mysqljoinmultipletables #mysqljoinontwocolumns #mysqljoinsyntax #mysqljointables #mysqljointwotables #mysqljointwotablesbyid #mysqljointwotableswithdifferentcolumns #mysqljointypes #mysqljoins #mysqljoinsexplained #mysqlleftjoin #mysqlleftjoinmultipletables #mysqlleftjoinnotworking #mysqlleftjoinnull #mysqlleftjoinwithcondition #mysqlleftjoinwithwhereclause #mysqlmergetablesexample #mysqlmergetablesfromdifferentdatabases #mysqlmergetableswithdifferentcolumns #mysqlmergetwotableswithdifferentcolumns #mysqlmergetwotableswithsamecolumns #mysqlouterjoin #mysqlouterjoinsyntax #mysqlqueryexamplesmultipletables #mysqlqueryfromtwotables #mysqlquerytwotables #mysqlsearchmultipletables #mysqlsearchmultipletablesinonequery #mysqlselectcolumnsfrommultipletables #mysqlselectfrommultipletables #mysqlselectfrommultipletableswithoutjoin #mysqlselectfromtwotablesatonce #mysqlselectmergetwotables #mysqlselectmultiplecolumnsfromdifferenttables #mysqltutorial #mysqlupdate #outerjoininsql #outerjoinmysql #phpmysqljoinmultipletables #phpmysqlleftjoinwhereclause #phpmysqlsearchmultipletablesusingakeyword #phpmysqlselectfrommultipletables #phpsqljoin #phpmyadminmergetwotables #querymultipletablesmysql #selectdatafrommultipletablesmysql #selectdatafrommultipletablesmysqlphp #selectfrom3tablesmysql #selectfrommultipletablessql #selectfromtwotableswithsamecolumnnamemysql #sqlcombinetwotables #sqlinnerjoin #sqljoin #sqljoin2tables #sqljoin3tables #sqljoin4tables #sqljoinmultipletables #sqljoinmultipletableswithconditions #sqljoinwhere #sqljoinwithwhereclauseexample #sqljoins #sqljoinsexplained #sqlleftjoin #sqlmergetwotableswithdifferentfields #sqlmergetwotableswithsamecolumns #sqlmultiplejoins #sqlon #sqlouterjoin #sqlqueryexamplesfrommultipletables #sqlselectfrommultipletableswithoutjoin #sqlunion #whentousecrossjoin Read the full article
