LEARN ABOUT PHP
db2_rollback
DB2_ROLLBACK(3) 1 DB2_ROLLBACK(3)
db2_rollback - Rolls back a transaction
SYNOPSIS
bool db2_rollback (resource $connection)
DESCRIPTION
Rolls back an in-progress transaction on the specified connection resource and begins a new transaction. PHP applications normally default
to AUTOCOMMIT mode, so db2_rollback(3) normally has no effect unless AUTOCOMMIT has been turned off for the connection resource.
PARAMETERS
o $connection
- A valid database connection resource variable as returned from db2_connect(3) or db2_pconnect(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Rolling back a DELETE statement
In the following example, we count the number of rows in a table, turn off AUTOCOMMIT mode on a database connection, delete all of
the rows in the table and return the count of 0 to prove that the rows have been removed. We then issue db2_rollback(3) and return
the updated count of rows in the table to show that the number is the same as before we issued the DELETE statement. The return to
the original state of the table demonstrates that the roll back of the transaction succeeded.
<?php
$conn = db2_connect($database, $user, $password);
if ($conn) {
$stmt = db2_exec($conn, "SELECT count(*) FROM animals");
$res = db2_fetch_array( $stmt );
echo $res[0] . "
";
// Turn AUTOCOMMIT off
db2_autocommit($conn, DB2_AUTOCOMMIT_OFF);
// Delete all rows from ANIMALS
db2_exec($conn, "DELETE FROM animals");
$stmt = db2_exec($conn, "SELECT count(*) FROM animals");
$res = db2_fetch_array( $stmt );
echo $res[0] . "
";
// Roll back the DELETE statement
db2_rollback( $conn );
$stmt = db2_exec( $conn, "SELECT count(*) FROM animals" );
$res = db2_fetch_array( $stmt );
echo $res[0] . "
";
db2_close($conn);
}
?>
The above example will output:
7
0
7
