Copy rows from one table to another, ignoring duplicates

Question

I have 2 tables (srcTable1 & destTable) that have identical schemas. I am trying to copy all rows from srcTable to destTable and ignore the duplicates. I thought I could

Answer 1

The solution that worked for me with PHP / PDO.

public function createTrainingDatabase($p_iRecordnr){
// Methode: Create an database envirioment for a student by copying the original
// @parameter: $p_iRecordNumber,    type:integer,   scope:local
// @var: $this->sPdoQuery,          type:string,    scope:member 
// @var: $bSuccess,                 type:boolean,   scope:local
// @var: $aTables,                  type:array,     scope:local
// @var: $iUsernumber,              type:integer,   scope:local
// @var: $sNewDBName,               type:string,    scope:local
// @var: $iIndex,                   type:integer,   scope:local 

// -- Create first the name of the new database --
$aStudentcard = $this->fetchUsercardByRecordnr($p_iRecordnr);
$iUserNumber = $aStudentcard[0][3];
$sNewDBName = $_SESSION['DB_name']."_".$iUserNumber;
// -- Then create the new database  --
$this->sPdoQuery = "CREATE DATABASE `".$sNewDBName."`;";
$this->PdoSqlReturnTrue();
// -- Create an array with the tables you want to be copied --
$aTables = array('1eTablename','2ndTablename','3thTablename');
// -- Populate the database --
for ($iIndex = 0; $iIndex < count($aTables); $iIndex++) 
{
 // -- Create the table --
    $this->sPdoQuery = "CREATE TABLE `".$sNewDBName."`.`".$aTables[$iIndex]."` LIKE `".$_SESSION['DB_name']."`.`".$aTables[$iIndex]."`;";
    $bSuccess = $this->PdoSqlReturnTrue();
    if(!$bSuccess ){echo("Could not create table: ".$aTables[$iIndex]."
");}
    else{echo("Created the table ".$aTables[$iIndex]."
");}
    // -- Fill the table --
    $this->sPdoQuery = "REPLACE `".$sNewDBName."`.`".$aTables[$iIndex]."` SELECT * FROM `".$_SESSION['DB_name']."`.`".$aTables[$iIndex]."`";
    $bSuccess = $this->PdoSqlReturnTrue();
    if(!$bSuccess ){echo("Could not fill table: ".$aTables[$iIndex]."
");}
    else{echo("Filled table ".$aTables[$index]."
");}
}

}
