A string that describes the error. An empty string if no error occurred.
Example Example 1. Object oriented style
<?php /* Open a connection */ $maxdb = new maxdb ( "localhost" , "MONA" , "RED" , "DEMODB" ); /* check connection */ if ( maxdb_connect_errno ()) { printf ( "Connect failed: %s\n" , maxdb_connect_error ()); $maxdb -> query ( "CREATE TABLE temp.mycity LIKE hotel.city" ); $maxdb -> query ( "INSERT INTO temp.mycity SELECT * FROM hotel.city" ); $query = "SELECT name, zip FROM temp.mycity ORDER BY name" ; $stmt = $maxdb -> prepare ( $query )) { /* drop table */ $maxdb -> query ( "DROP TABLE temp.mycity" ); /* execute query */ $stmt -> execute (); printf ( "Error: %s.\n" , $stmt -> error ); /* close statement */ $stmt -> close (); /* close connection */ $maxdb -> close (); ?>
Example 2. Procedural style
<?php /* Open a connection */ $link = maxdb_connect ( "localhost" , "MONA" , "RED" , "DEMODB" ); /* check connection */ if ( maxdb_connect_errno ()) { printf ( "Connect failed: %s\n" , maxdb_connect_error ()); maxdb_query ( $link , "CREATE TABLE temp.mycity LIKE hotel.city" ); maxdb_query ( $link , "INSERT INTO temp.mycity SELECT * FROM hotel.city" ); $query = "SELECT name, zip FROM temp.mycity ORDER BY name" ; $stmt = maxdb_prepare ( $link , $query )) { /* drop table */ maxdb_query ( $link , "DROP TABLE temp.mycity" ); /* execute query */ maxdb_stmt_execute ( $stmt ); printf ( "Error: %s.\n" , maxdb_stmt_error ( $stmt )); /* close statement */ maxdb_stmt_close ( $stmt ); /* close connection */ maxdb_close ( $link ); ?>
The above examples would produce the following output:
Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
Error: POS(23) Unknown table name:MYCITY.
