Combine data from multiple columns into a single column using Microsoft Access SQL


You can achieve it by using the UNION SQL query as in the following example:

SELECT field_1[, field_2,…]
FROM table_1[, table_2,…]
UNION [ALL]
SELECT field_a[, field_b,...]
FROM table_a[, table_b,…];

Pertinent to your case, it should look like the following:

SELECT col1
FROM table_1
UNION
SELECT col2
FROM table_1
UNION
SELECT col3
FROM table_1;

If it is possible, merge those images beforehand in your graphic editor of choice. If you can only do it in runtime, you will either h

Collapsing values from multiple rows into a single row of generated columns
You could look into playing with the PIVOT statement, but I'm not so sure you'll get exactly what you're after. However, this would also work: SELECT MAX(CASE x WHEN 1 THEN y END) AS c1, MAX(CASE x WHEN 2 THEN y END) AS c2, MAX(CASE x WHEN 3 THEN y END) AS c3 FROM @t
