sqlanywhere_errorcode
Prototype
int sqlanywhere_error( [ resource link_identifier
] )
Description
Returns the error code of the most-recently executed SQL Anywhere
PHP function. Error codes are stored per connection. If no link_identifier is
specified, then sqlanywhere_errorcode returns the last error code where no
connection was available. For example, if you are calling sqlanywhere_connect
and the connection fails, then call sqlanywhere_errorcode with no parameter
for the link_identifier to get the error code. If you want to get the
corresponding error message use the sqlanywhere_error function.
Parameters
link_identifier A link
identifier that was returned by sqlanywhere_connect or sqlanywhere_pconnect.
Returns
An integer representing a SQL Anywhere error code. An error code of
0 means success. A positive error code indicates success with warnings. A
negative error code indicates failure.
Example
This example shows how you can retrieve the last error code from a failed SQL
Anywhere PHP call.
$result = sqlanywhere_query( $conn, "SELECT * FROM table_that_does_not_exist" );
if( ! $result ) {
$error_code = sqlanywhere_errorcode( $conn );
echo "Query failed. Reason: $error_code";
}
