mysql_stmt_error(MYSQL_STMT *stmt)
For the statement specified by stmt,
mysql_stmt_error() returns a
null-terminated string containing the error message for the
most recently invoked statement API function that can succeed
or fail. An empty string ("") is returned
if no error occurred. Either of these two tests can be used to
check for an error:
if(*mysql_stmt_errno(stmt))
{
// an error occurred
}
if (mysql_stmt_error(stmt)[0])
{
// an error occurred
}
If the failed statement API function was
mysql_stmt_close(), do not
call mysql_stmt_error() to
obtain error information because
mysql_stmt_close() makes the
statement handler invalid. Call
mysql_error() instead.
The language of the client error messages may be changed by recompiling the MySQL client library. You can choose error messages in several different languages.
