You can display tables for only one user at a time. When you click a different user
name, PeriSQL:
• removes the tables for the previous user from the display
• writes the new user’s tables to the scrolling list
• titles the scrolling list with the new account name
PeriSQL Columns
When you select a table, PeriSQL displays the set of columns for that table below the
table objects list. The title of the scrolling list identifies the selected table.
You can display the columns for up to four tables at one time; PeriSQL labels each list
with the appropriate table name. Each list contains a fixed set of columns.
• Select a column to include it in the SQL command.
• You can select multiple columns from one or more of the displayed tables.
• To deselect a column, click it again.
The columns of a table describe the attributes of the data residing in the table. Each
column has a name and specific characteristics.
