Question

Does anyone have any idea how to construct a select statement querying a temp table that contains the following data:

Code    |Col1     | Col2| Col3
----------------------------------------
ABCD    |AAASTRING|NULL |  NULL
ABCD    |NULL     |BBBSTRING |  NULL
ABCD    |NULL     |NULL |  CCCSTRING

… that will merge the results as follows?

Code    |Col1   | Col2 | Col3
---------------------------------------
ABCD    |AAASTRING| BBBSTRING | CCCSTRING

Your help would be greatly appreciated!

Try this:

SELECT
    Code,
    MAX(Col1) AS Col1,
    MAX(Col2) AS Col2,
    MAX(Col3) AS Col3
FROM your_table
GROUP BY Code
