When you create scripts for a PowerBuilder application, you can use embedded SQL statements in the script to perform operations on the database. The features supported when you use embedded SQL depend on the DBMS to which your application connects.
When you use the Informix IN9 database interface to connect to a database, you can use embedded SQL in your scripts. You can embed the following types of SQL statements in scripts and user-defined functions:
Transaction management statements
Non-cursor statements
Cursor statements
Database stored procedures
The Informix database interfaces use the Informix application programming interface (API) to interact with the database.
When you use embedded SQL, PowerBuilder makes the required calls to the API. Therefore, you do not need to know anything about the Informix API in order to use embedded SQL in PowerBuilder.
