PDO::errorInfo() returns an array of error information about the last operation performed by this database handle. The array consists of the following fields:
Element | Information |
---|---|
0 | Generic PDO error code corresponding to one of the PDO_ERR_* constants. |
1 | Driver-specific error code. |
2 | Driver-specific error message. |
PDO::errorInfo() only retrieves error information for operations performed directly on the database handle. If you create a PDOStatement object through PDO::prepare() or PDO::query() and invoke an error on the statement handle, PDO::errorInfo() will insert an error code of PDO_ERR_NONE into the first element of the returned array. You must call PDOStatement::errorInfo() to return the error information for an operation performed on a particular statement handle.
上の例の出力は以下となります:
Error: a requested database object does not exist. Driver-specific error code: -204 Driver-specific message: [SQLExecute: -204 [IBM][CLI Driver][DB2/NT] SQL0204N "DB2INST1.BONES" is an undefined name. SQLSTATE=42704 [SQL State 42S02] (..\pecl\pdo_odbc\odbc_stmt.c:80)] |
