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.
