I am trying to make a query in mysql to get any column that has a specific value for a specific row. In Mysql we can get rows based on any specific value of a column.
I have a table like this:
+----+------------+------------+---------------+---------------+---------+----------------+--------- | ID | MSISDN | MissedCall | SponsoredCall | AdvanceCredit | ACvalue | SuitablePackId | AutoTimeStamp | +----+------------+------------+---------------+---------------+---------+----------------+---------------------+ | 1 | 9944994488 | 1 | 0 | 1 | 0 | 1 | 2014-09-18 10:42:55 | | 4 | 9879877897 | 0 | 1 | 0 | 0 | 2 | 2014-09-18 10:42:55 | +----+------------+------------+---------------+---------------+---------+----------------+---------------------+
What I need is that when I select a row based on MSISDN, it should return all the column names of that row with a fixed value (e.g. 1).
Therefore, in the above table, MSISDN = 9944994488 should return
MissedCall AdvanceCredit SuitablePackId
What I tried is:
SELECT COLUMN_NAME as names FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'bi' AND TABLE_NAME = 'useranalysisresult'
This returns the column names of the table. But how to get column name with specific value. Thanks for your help in advance.

The comment is too long.
SQL queries return a fixed set of columns. You cannot change settings on a row basis. You can use prepared statements to do what you want, although this may seem like a mysterious approach.
You can return a column containing values concatenated together. Something like this:
select concat_ws(',', (case when MissedCall = 1 then 'Missed Call' end), (case when SponsoredCall = 1 then 'Sponsored Call' end), . . . ) from useranalysisresult;This will generate a list in a single column of the flags that are set.
