fbsql_errno
(PHP 4 >= 4.0.6, PHP 5)
fbsql_errno — Returns the error number from previous operation
Description
int fbsql_errno
([ resource $link_identifier
] )
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.
Parameters
-
link_identifier
-
A FrontBase link identifier
returned by fbsql_connect() or
fbsql_pconnect().
If optional and not specified,
the function will try to find an open link to the FrontBase server and if no
such link is found it will try to create one as if
fbsql_connect() was called with no arguments
Return Values
Returns the error number from the last fbsql function, or
0 (zero) if no error occurred.
Examples
