DBTester offers 6 functions. You can use them directly in your test cases:

1. DB_Connect: Opens a database connection linking the data through the specified OBDC DSN name. DB_Connect returns a connection handle which can be used on other DBTester functions. SQL statements can be submitted to the database. For example: con = DB_Connect("dsn=dsn_name")

2. DB_Disconnect: Closes the database connection represented by the speficied connection handle. All resources related to this connect are also released. For example: DB_Disconnect(con)

3. DB_ExecuteSql: Sends the specified SQL statement to the specified database connection for execution. DB_ExecuteSql returns a query result handler which can be used by the DB_FetchNext function. For example: res = DB_ExecuteSql(con, "SELECT * FROM ...")

4. DB_FetchNext: Retrieves the next row from the specified query result handler. For example: DB_FetchNext(res, col1, col2, col3, ...)

5. DB_FetchPrevious: Retrieves the previous row from the specified query result handler.

6. DB_FinishSql: Closes the specified query result handler. For example: DB_FinishSql(res)
