ingres_errsqlstate — Get 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
link- The connection link identifier
返回值
Returns a string containing the last SQLSTATE, or NULL if no error has occurred.
