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 may 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.
User Comments
If you want installation-language-neutral (that is, always in English) error reporting that is more descriptive than the numerical error codes, you may wish to convert the names of the constants from mysqld_error.h into text strings.
