ingres_errsqlstate

(PECL ingres:1.1-1.4.3)

ingres_errsqlstate — Gets the last SQLSTATE error code generated

说明

string ingres_errsqlstate ([ resource $link ] )

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

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

返回值

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