PDO::exec -- Execute an SQL statement and return the number of affected rowsVarovanie |
T�to funkcia je EXPERIMENT�LNA. Spr�vanie tejto funkcie, n�zov tejto funkcie a hoci�o in� zdokumentovan� o tejto funkcii sa m�e zmeni� bez pov�imnutia v bud�com vydan� PHP. Pou��vajte t�to funkcii na svoje vlastn� riziko. |
PDO::exec() prepares and executes an SQL statement in a single function call, returning the number of rows affected by the statement.
PDO::exec() does not return results from a SELECT statement. For a SELECT statement that you only need to issue once during your program, consider issuing PDO::query(). For a SELECT statement that you need to issue multiple times, prepare a PDOStatement object with PDO::prepare() and issue the statement with PDOStatement::execute().
PDO::exec() returns the number of rows that were modified or deleted by the SQL statement you issued. If no rows were affected, PDO::exec() returns 0.
