ingres_errsqlstate

(PECL ingres >= 1.1.0)

ingres_errsqlstateGet the last SQLSTATE error code generated

说明

ingres_errsqlstate ([ resource $link ] ) : string

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

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

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

参数
