One of the primary uses of Interactive SQL is to browse table data. Interactive SQL retrieves information by sending a request to your database server. The database server, in turn, looks up the information, and returns it to Interactive SQL.
After you execute a SELECT statement, the result set appears on the Results tab in the Results pane. By default, row numbers appear to the left of the result set.
The database server creates schema locks on tables that you view in Interactive SQL, even if you do not modify the table.
However, you can configure Interactive SQL to attempt to release the database schema locks it creates when it displays your result set. To do so, in Interactive SQL, click Tools » Options » SQL Anywhere, and click Automatically Release Database Locks.
When this option is selected, after you execute a statement that returns a result set, Interactive SQL checks if your connection has any uncommitted changes in the database. If none exist, then Interactive SQL releases your schema locks; otherwise, Interactive SQL does not release your schema locks. That is, Interactive SQL does not release your schema locks if you have any uncommitted changes to the database.
