How To Duplicate Or Copy/Paste Entire Row In MySQL Same Table Using PHP?

MySQL allows you to copy data across tables and databases, using SELECT and INSERT statements. In some cases, you may need to copy a row and insert into the same table in MySQL. This is often required to create test data for quality checks or duplication of data. In this article, we will learn how to do this.

On a recent large-scale web application we were developing, I came across a need to clone complete rows from a MySQL table to the same table. Initially, we were having 2.5 million product rows in the table. Our requirement was to test our application performance to load it with 1 million products.

There were suggestions around the web to copy the rows into a new table and then copy them back to the original table to avoid duplicate key issues for indexed ID ( primary key ). But I just have a simple idea. Just the below query will do the job of cloning entire rows into the same table without conflicting primary key

How To Duplicate Or Copy/Past Entire Row in MySQL Same Table Using PHP?

There are a few easy and understandable steps to achieve your desired functionality that we are gonna share below. Follow each step perfectly.

PHP:

function DuplicateMySQLRecord($connection, $table, $id_field, $id) {
$newid = 0;
// load the original record into an array
$result = mysqli_query($connection, "SELECT * FROM {$table} WHERE {$id_field}={$id}");
if(!$result){ 
echo "ERROR-DuplicateMySQLRecord: '".mysqli_error($connection)."'";
return $newid;
} else {
// echo "Success";
$original_record = mysqli_fetch_assoc($result);

// insert the new record and get the new auto_increment id
$garb = mysqli_query($connection, "INSERT INTO {$table} (`{$id_field}`) VALUES (NULL)");
if(!$garb){ 
echo "ERROR-DuplicateMySQLRecord: '".mysqli_error($connection)."'";
return $newid;
} else {
// echo "Success";
$newid = mysqli_insert_id($connection);

// generate the query to update the new record with the previous values
$query = "UPDATE {$table} SET ";
foreach ($original_record as $key => $value) {
if ($key != $id_field) {
$query .= '`'.$key.'` = "'.str_replace('"','\"',$value).'", ';
}
}
$query = substr($query,0,strlen($query)-2); # lop off the extra trailing comma
$query .= " WHERE {$id_field}={$newid}";
if(!mysqli_query($connection, $query)){ 
echo "ERROR-DuplicateMySQLRecord: '".mysqli_error($connection)."'";
return $newid;
} else {
// echo "Success";
// return the new id
return $newid;
}
}
}
}
