Using the SQL Genie

Description

The SQL Genie helps you write SQL expressions. This page contains some pointers on how to use it.

The SQL Genie helps you write SQL expressions. To start the SQL Genie:

  1. Create a SQL::Connection object and open a connection to AlphaSports.mdb.

  2. Pass the SQL::Connection object to the SQL_Query_Builder() function. 

    dim qry as C
dim conn as SQL::Connection
conn.open("{A5API=Access,FileName='C:\Program Files\a5v8\MDBFiles\Alphasports.mdb',UserName='Admin'}")
qry = sql_query_builder(conn)
    This opens the SQL Genie and displays its Tables tab.

  3. Click Add Table to display the Add Table dialog.

  4. Select "Customer" and click OK. When you return to the SQL Genie, you will see the start of your SQL expression in the SQL window.
