Access this window from the Table/Joins tab of the Query Builder.
This shows you the tables and joins in your query, and has some further options not possible from the GUI window.
Tables can have a table-id, which is an short name for referencing the table. The table-id is also referred to as the “correlation name”. Using table-ids makes the SQL less voluminous and easier to read.
If a table appears twice in the query, it is essential to have a table-id to distinguish which of the two instances of the table you are referring to.
AQT will by default generate a table-id for the tables. To change this, click in the Table Id column and enter/amend the value. Then hit Enter or click elsewhere to effect the change.
The Options Tab allows you to set a number of options about how this table-id is generated.
This allows you add a new table to your query.
After adding a new table to the query, you will be asked to specify a join for this table.
See the topic Using Table Expressions for a description of this.
This allows you to delete a table from the query.
These are discussed in the topic Creating or Modifying Joins
