fbsql_errno — Returns the error number from previous operation
$link_identifier
= ?
) : intReturns 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.
link_identifier
Um identificador de link FrontBase retornado porfbsql_connect() ou fbsql_pconnect().
Se opcional e não especificado a função tentará localizar um link aberto ao um servidor FrontBase e se nenhum link for encontrado será tentado criar um como se fbsql_connect() fosse chamado sem argumentos.
Returns the error number from the last fbsql function, or
0
(zero) if no error occurred.
