Data Definition Files

A data definition file (also called SQL script) is a text file that contains SQL statements. You can execute it in the Interactive SQL window of the IBConsole. To create, open or modify data definition files, you can use a text editor such as Notepad.

It is often convenient to create a data definition file rather than typing each statement, because the text editor provides you with an editing environment and the script provides a reusable record of what was entered. In practice, most data definition is done using data definition files.

The CONNECT Statement

Every SQL script must begin with a CONNECT statement. The CONNECT statement specifies a complete path to the database, a user name, and a password. However, if you connect to a database beforehand, you may omit the CONNECT statement when executing an SQL script in the Interactive SQL window.

If you do specify a connect statement, make sure to modify the values accordingly. The SQL scripts that accompany this tutorial begin with the following CONNECT statement:

CONNECT 'C:\ProgramData\Embarcadero\InterBase\gds_db\examples\database\TUTORIAL.IB'
USER 'TUTOR' PASSWORD 'tutor4ib'

Before executing a script with the above CONNECT statement, do one of the following:

  • Comment-out the statement (see Comment for more information).
  • Modify the path.
