DAC for MySQL™

Direct Access Components for MySQL
Microolap Direct Access Components for MySQL and Delphi/C++ Builder (also known as MySQLDAC) is a Borland Delphi/C++Builder component set for direct connect to MySQL database server. DAC for MySQL allows you to create Delphi/C++Builder applications without BDE, ODBC, ADO and without libmysql.dll.

DAC for MySQL Components:

TMySQLDatabase provides discrete control over a connection to a single database in a database application.
Use TMySQLDatabase when a database application requires any of the following control over a database connection:
  • Persistent database connections;
  • Customized database server logins;
  • Transaction control;
  • Single-value queries.
TMySQLTable encapsulates a database table.
Use TMySQLTable to access data in a single database table. TMySQLTable provides direct access to every record and field in an underlying database table. TMySQLTable can also work with a subset of records within a database table using ranges and filters.
At design time, create, delete, update, or rename the database table connected to a TMySQLTable by right-clicking on the TMySQLTable and using the pop-up menu.
TMySQLQuery encapsulates a dataset with a result set that is based on an SQL statement.
Use TMySQLQuery to access one or more MySQL tables in a database using SQL statements.
TMySQLQuery component is useful because it can:
  • Access more than one table at a time (called a "join" in SQL).
  • Automatically access a subset of rows and columns in its underlying table(s), rather than always returning all rows and columns.
  • Access multi-resultset queries.
TMySQLUpdateSQL applies cached updates on behalf of queries or stored procedures that can't post updates directly.
Use a TMySQLUpdateSQL object to provide SQL statements used to update read-only datasets represented by TMySQLQuery component. A dataset is read-only either by design or circumstance. If a dataset is read-only by design, the application itself does not provide a user interface for updating data, but may institute a programmatic scheme behind the scenes. If a dataset is read-only by circumstance, it indicates that the MySQL returned a read-only result set. This usually happens for queries made against multiple tables. Such queries are, by SQL-92 definitions, read-only.
TMySQLStoredProc provides functionality for using stored procedures in MySQL.

TMySQLStoredProc works with two types of stored procedures: with or without a result set (for the first type use Open() method or set Active property to True, for the second - use ExecProc() method).

When the procedure name is put in the ProcedureName property, the component fetches information on parameters of the procedure from the server and puts it in the Params property according to parameters' types. This component provides full support of IN, OUT and INOUT parameters.
TMySQLDirectQuery is component for high-speed (3-4 times faster then with TMySQLQuery component) data fetching. But it is not TDataset compatible.
TMySQLBatchExecute component can execute SQL scripts containing more than one SQL statement.
TMySQLMacroQuery is the descendant of TMySQLQuery component and supports all of its properties, methods, events, and functionalities. The difference is in Macros and MacroChar properties which help to modify SQL script text in design-time and run-time with easy.
TMySQLMonitor monitors dynamic SQL passed to the MySQL server.
TMySQLDump allows to get SQL script with a dump of a DataBase.
This script can be executed on another MySQL server by TMySQLBatchExecute component.
TMySQLTools component allows to run MySQL diagnostic and repair operations such as Repair, Check, Analyze, Optimize, Backup and Restore.
TBDE2MySQLDAC class is intended for the easy conversion of BDE Database Objects into DAC for MySQL Database Objects.
