fbsql_errno
(PHP 4 >= 4.0.6, PHP 5)
fbsql_errno — Returns the error number from previous operation
설명
int fbsql_errno
([ resource $link_identifier
] )
Returns the numerical value of the error message from previous FrontBase operation.
Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno() to retrieve the error code. Note that this function only returns the error code from the most recently executed fbsql function (not including fbsql_error() and fbsql_errno()), so if you want to use it, make sure you check the value before calling another fbsql function.
반환값
Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.
