can any one help me on how can I create a query output using the row data on the source table as a header on my output. Please see below for illustration.
E.G.
Row Data:
+-----------+----------+ | colHeader | value | +-----------+----------+ | Header1 | value 1 | +-----------+----------+ | Header2 | value 2 | +-----------+----------+ | Header3 | value 3 | +-----------+----------+
Output:
+-----------+-----------+-----------+ | Header1 | header2 | Header3 | +-----------+-----------+-----------+ | Value 1 | value 2 | Value 3 | +-----------+-----------+-----------+
Is it possible??
Here is my MySQL script. I don’t think if is it the right way. Is there any idea on how could i arrive on the above output?
SELECT t1.value AS `Header1`, t2.value AS `Header2`, t3.value AS `Header3` FROM (SELECT * FROM table1 WHERE colHeader='Header1') t1 JOIN (SELECT * FROM table1 WHERE colHeader='Header2'3) t2 JOIN (SELECT * FROM table1 WHERE colHeader='Header3') t3;

Method 1
How about this??
SELECT GROUP_CONCAT(if(colHeader = 'Header 1', value, NULL)) AS 'Header 1', GROUP_CONCAT(if(colHeader = 'Header 2', value, NULL)) AS 'Header 2', GROUP_CONCAT(if(colHeader = 'Header 3', value, NULL)) AS 'Header 3' FROM myTable;

Note, you will need GROUP BY
statement when there are more data of ids as shown below in Demo 2.
