Options

• Join type
  Specify whether you want to use an inner join, left outer join, or full join.

• Swap Inputs
  Switch the order between inputs by using the Swap Inputs button. This selection may be useful with the Left outer join option.

• Input
  For each column that you want in the merged output, first select from the list of available inputs.

Inputs are displayed in two separate tables. Select columns to include in the output. Drag columns to create a join between the tables. To delete a join, select it and then press the DELETE key.

• Input Column
  Select a column to include in the merged output from the list of available columns on the selected input.

• Output Alias
  Type an alias for each output column. The default is the name of the input column; however, you can choose any unique, descriptive name.
