ingres_error - Get a meaningful error message for the last error generated
SYNOPSIS
string ingres_error ([resource $link])
DESCRIPTION
Returns a string containing the last error, or NULL if no error has occurred.
If a $link resource is passed to ingres_error(3), it returns the last error recorded for the link. If no link is passed then
ingres_error(3) returns the last error reported using the default link.
The function, ingres_error(3), should always be called after executing any database query. Calling another function before ingres_error(3)
is called will reset or change any error message from the last Ingres function call.
PARAMETERS
o $link
- The connection link identifier
RETURN VALUES
Returns a string containing the last error, or NULL if no error has occurred.
