The Query-language option
Use the Query-language option to enter, modify, save, retrieve, and run SQL statements. DB-Access retains the statements, if any, in the editor. These statements are called the current statements.
Use the Query-language option to:
- Learn SQL and SPL.
For example, use the Query-language option to practice the examples in the HCL Informix® Guide to SQL: Tutorial.
- Create and alter table structures as an alternative to the DB-Access Schema Editor.
- Select, display, add, update, and delete data.
The SQL menu has the following options.
Option | Purpose |
---|---|
New | Clears current statements and positions cursor in SQL editor. |
Run | Runs current SQL statements. A message is displayed or the data that is retrieved by a query is displayed with the number of rows retrieved. |
Modify | Allows you to modify current SQL statements in SQL editor. |
Use-editor | Starts a system editor so that you can modify current statements or create new statements. Use-editor is interchangeable with New and Modify. |
Output | Redirects Run-option output to a file, printer, or system pipe. |
Choose | Lists SQL command files so that you can choose a file to run or modify. |
Save | Saves current SQL statements in a file for later use. |
Info | Shows table information, such as columns, indexes, privileges, constraints, triggers, status, and fragmentation strategy. |
Drop | Deletes a specified SQL command file. |
Exit | Returns to main menu. |
