const char *mysql_stmt_error(MYSQL_STMT *stmt)
Description
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. This means the following two tests are equivalent:
if (mysql_stmt_errno(stmt))
{
// an error occurred
}
if (mysql_stmt_error(stmt)[0])
{
// an error occurred
}
The language of the client error messages many be changed by recompiling the MySQL client library. Currently you can choose error messages in several different languages.
Return Values
A character string that describes the error. An empty string if no error occurred.
Errors
None.
