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

3. Select the macro and click Edit.
4. In the Presets tab select Lookup tables preset.
5. Select the column for matching records and click Next.
6. Define the parameters if needed.

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'
