Inserting data in oracle DB using oci_8
. Sample query to insert string with special characters or quotes
update TABLENAME set COMMENTS = 'As per Mark's email dated 28-Feb-2015 - Bill Gates & Team's effort' where ID = 99;
To insert/update
$query = 'update TABLENAME set COMMENTS = '$_POST[comments]';
$result = customexecute($new_query);
public function customexecute($query)
{
$resutlt = parent::customquery($query);
return $resutlt;
}
public static function customquery($query)
{
try{
$stmt = oci_parse($conn, $query);
oci_execute($stmt,OCI_COMMIT_ON_SUCCESS);
oci_commit(db_singleton::getInstance());
oci_free_statement($stmt);
}catch (Exception $e)
{
print_r($e);
}
}
Executing it on ORACLE DB it says SQl command not properly ended.
Looked into Parameterized queries
mentioned here but not able to integrate it succesfully.
$query = 'UPDATE tablename SET field = :field WHERE id = :id';
$stmt = oci_parse($oracleConnection, $query);
oci_bind_by_name($stmt, ':field', "The field value with 'apostrophes' and so");
oci_bind_by_name($stmt, ':id', '125');
$result = oci_execute($stmt);
I can pass :bind_comments
in my query which is in my controller. But $stmt
resides in my db_singleton file (general for all DB queries) and can not pass seperately for a individual query.
How can I sanitize user input or do not allow data to be used in creating SQL code
