PHP Manual: Returns the last error found

Description

array oci_error ([ resource $resource ] )

Returns the last error found.

The function should be called immediately after an error occurs. Errors are cleared by a successful statement.

Parameters

resource: For most errors, resource is the resource handle that was passed to the failing function call. For connection errors with oci_connect, oci_new_connect or oci_pconnect do not pass resource.

Return Values

If no error is found, oci_error returns FALSE. Otherwise, oci_error returns the error information as an associative array.

**oci_error Array Description**
Array key	Type	Description
code	integer	The Oracle error number.
message	string	The Oracle error text.
offset	integer	The byte position of an error in the SQL statement. If there was no statement, this is 0
sqltext	string	The SQL statement text. If there was no statement, this is an empty string.
