How to convert a column header and its value into row in sql?
sql, sql-server-2008
Solution
Maybe something like this:
Test data
DECLARE @T TABLE(Col1 INT, Col2 INT, Col3 INT)
INSERT INTO @T
VALUES (1,1,1)
Query
SELECT
*
FROM
(
SELECT
t.Col1,
t.Col2,
t.Col3
FROM
@T AS t
) AS SourceTable
UNPIVOT
(
Value FOR Col IN
(Col1,Col2,Col3)
) AS unpvt
Output
1 Col1
1 Col2
1 Col3
Problem
I have a table with columns say `col1, col2, col3`. The table has many rows in it. Let's assume `val1, val2, val3` is one such row. I want to get the result as ``` Col1, Val1 Col2, Val2 Col3, Val3 ``` That is 3 rows - one for each column and its value. I am using SQL Server 2008. I read about pivots. Are pivots a way to solve this problem? Can someone route me to some examples or solutions how to solve this problem? Thanks a lot
