fbsql_errno

(PHP 4 >= 4.0.6, PHP 5, PHP 7)

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.

인수

link_identifier

fbsql_connect()나 fbsql_pconnect()가 반환한 FrontBase 연결 식별자.

선택적이고 지정하지 않았을 때, 함수는 FrontBase 서버로 열려있는 연결을 찾고, 찾지 못하면 fbsql_connect()를 인수 없이 호출했을 때처럼 연결을 시도합니다.

반환값

Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.
