Database Guide


Database definition classes

The database definition classes provide a means for defining queries, stored procedures, connection specifications, and logon specifications. These classes store the information that you use to access connected databases.

AbtDatabaseConnectionSpec
Associates a connection alias with a database manager and a specific database. Connection aliases provide a means of creating database applications independent of specific database names. This independence enables you to develop and test an application with one database, for example, and then switch to a different database for production use without having to redefine your queries.

AbtDatabaseLogonSpec
Associates a user ID, password, and database server with an alias.

AbtQuerySpec
Defines SQL statements to be passed to a database management system by the database connection classes.

AbtStoredProcSpec
Defines stored procedures and the input and output parameters to passed with them
