Qore MysqlSqlUtil Module Reference  1.4.1
MysqlSqlUtil Module

MysqlSqlUtil Module Introduction

The MysqlSqlUtil module provides a high level API for working with MySQL database objects.

Usually this module is loaded on demand from the SqlUtil module, however to use this module directly, use "%requires MysqlSqlUtil" in your code.

All the public symbols in the module are defined in the MysqlSqlUtil namespace

This module requires the mysql binary module for communication with MySQL databases

Schema Management on MySQL

Type Mapping

Column types are mapped from Qore types as follows:

MySQL Column Type Mappings

Generic Type Name MySQL Type Used
float double
number decimal
string varchar
date datetime
binary varbinary
bool tinyint
SqlUtil::BLOB mediumblob
SqlUtil::CHAR char
SqlUtil::CLOB mediumtext
SqlUtil::NUMERIC decimal
SqlUtil::VARCHAR varchar

To use other types, use the "native_type" column description option with the native MySQL type name instead (under the "driver" and "mysql" keys for schemas supporting multiple databases).

NOT NULL Constraints on MySQL

MySQL currently does not support firing "before insert" or "before update" triggers before constraints are checked, so in other databases where a trigger will set a default value for a column when a NULL is inserted, MySQL will raise an error if there is a NOT NULL constraint on the column.
