Use the Options section to specify how the Column Generator stage operates.

Column method

Select Explicit if you are going to specify the column or columns you want the stage to generate data for. Select Schema File if you are supplying a schema file containing the column definitions.

Column to generate

When you have chosen a column method of Explicit, this property allows you to specify which output columns the stage is generating data for. Repeat the property to specify multiple columns. You can specify the properties for each column using the Parallel tab of the Edit Column Meta Dialog box (accessible from the shortcut menu on the columns grid of the output Columns tab). You can use the Column Selection dialog box to specify several columns at once if required.
