Merge Tables preset
Selecting preset
Switch the page to the edit mode.
Insert the Table Transformer macro and paste the tables or the macros outputting tables within the macro body.
Select the macro and click Edit.
In the Presets tab select Merge tables preset and click Next.
Define the parameters if needed.
Save the macro and the page.
The default SQL query works with no need to change it:
When the columns have the same column labels (look here to learn what query to use when the column labels differ)
When the columns are both in the same or in the different orders
SQL query explanation
In the SQL query tab in the macro browser you can find the default query:
SELECT * FROM T*
SELECT * outputs all columns from source tables. Replace the asterisk with a comma separated list of column labels in single quotes to output only these columns in the merged table:
SELECT 'Name', 'Age' FROM T*
FROM T* gets data from all tables within the macro body. Replace the asterisk with the number of the table to use the particular table only:
SELECT 'Name', 'Age' FROM T1
SQL query when the column labels differ
If you want to merge tables with different column labels, use this query example that outputs the column Job from the second table as the column Position:
SELECT * FROM T1 UNION SELECT *, 'Job' AS 'Position' FROM T2

SQL query explanation
In the SQL query tab in the macro browser you can find the default query:
SELECT * FROM T1 OUTER JOIN T* ON T1.'Name' = T*.'Name'
SELECT * outputs all columns from source tables. Replace the asterisk with a comma separated list of column labels in single quotes to output only these columns in the merged table:
SELECT T1.'Name', T1.'Age', T2.'Certification' FROM T1 OUTER JOIN T* ON T1.'Name' = T*.'Name'
OUTER JOIN T* looks up all tables. You can also use other functions:
- OUTER JOIN outputs all rows from all tables even if there are no matches.
- JOIN outputs only those rows, that have matches.
- LEFT JOIN outputs all rows from the first table even if there are no matches.
- RIGHT JOIN outputs all rows from the second table even if there are no matches.
ON T1.'Name' = T*.'Name' is the matching criteria. The rows in the merged table should match on the column Name.
SQL query when the column labels differ
If you want to join tables with different labels of columns for matching, use this query example. The rows in the joint table should match by the column Id for Table 1, # for Table 2, N for Table 3:
SELECT T1.'Id', T1.'Full name', T2.'Login', T3.'Personal space', T3.'Create space', T3.'Confluence admin', T3.'System admin' FROM T1 JOIN T2 ON T1.'Id' = T2.'#' JOIN T3 ON T1.'Id' = T3.'N'
SQL query when joining tables with chain look up
If you want to merge two tables by one criterion and the third table by another criterion, use this query. Table 1 matches Table 2 by Login or name, then Table 3 matches them by Level:
SELECT T1.'Full name', T2.'Level', T3.'Personal space', T3.'Create space', T3.'Confluence admin', T3.'System admin' FROM T1 JOIN T2 ON T1.'Login' = T2.'Name' JOIN T3 ON T2.'Level' = T3.'Level'

The following view options are available in the Table Transformer macro:
- Show/Hide source data
- Show result as plain text
- Export to CSV button
- Export to PDF button
- Export to Word button
