If a <parameter>link</parameter> resource is passed to
|
|
<function>ingres_error</function>, it returns the last error recorded for
|
|
the link. If no link is passed then <function>ingres_error</function>
|
|
returns the last error reported using the default link.

The function, <function>ingres_error</function>, should always be called
|
|
after executing any database query. Calling another function before
|
|
<function>ingres_error</function> is called will reset or change any
|
|
error message from the last Ingres function call.
