Creating and editing Sybase Adaptive Server temporary tables

You can create and edit temporary tables in the Database painter, SQL painter, or DataWindow painter when you use the PowerBuilder SYC native driver to connect to an ASE database. Temporary tables persist for the duration of a database connection, residing in a special database called “tempdb”.

You add a temporary table to the tempdb database by assigning a name that starts with the # character when you create a new table in a PowerBuilder painter. (Temporary tables must start with the # character.)

After you create a temporary table, you can create indexes and a primary key for the table. If you define a unique index or primary key, you can execute INSERT, UPDATE, and DELETE statements for a temporary table. Selecting Edit Data from the pop-up menu of a temporary table retrieves data that you store in that table.

NoteStandard catalog query limitations When you click Refresh from the pop-up menu for the Tables node in the Database painter or the Objects view of the DataWindow painter, the list of tables displays temporary tables even though they exist only in the tempdb database. However, once you refresh table definitions from the database, the Objects view can no longer list the index or primary key information of the temporary tables, and the Layout view can no longer display that information graphically.
