ingres_error

(PECL ingres:1.1-1.4.3)

ingres_error — Gets a meaningful error message for the last error generated

说明

string ingres_error ([ resource $link ] )

Returns a string containing the last error, or NULL if no error has occurred.

If a link resource is passed to ingres_error() it returns the last error recorded for the link. If no link is passed then ingres_error() returns the last error reported using the default link.

The function, ingres_error(), should always be called after executing any database query. Calling another function before ingres_error() is called will reset or change any error message from the last Ingres function call.

参数

link: The connection link identifier. If not specified, the last opened link is used.

返回值

Returns a string containing the last error, or NULL if no error has occurred.
