In the Columns list, select the columns you want to include in the SELECT clause. You can select one or more columns, or none.

You can use the Columns pop-up menu to select or deselect multiple columns in the list.

The list shows the columns in each of the tables and views you have selected in the Tables/views list. The column names are fully qualified, and take the following form <table or view name>.<column name>.

For the SELECT statement to be valid, you must include at least one column or computed column in the SELECT clause.

If SELECT * is selected, Columns is not available.
