I have table fieldstatus where field and flag column are there.

In this table field contains the list of fields from table mstchvs.
Now here there is flag column which contains 1 or 0.


If i write select * from mstchvs
I get all the column names.

But i want to list those columns where field=0 in fieldstatus table.

i,e

select (column names from fieldstatus table where flag=0) from mstchvs

Assuming field contains a comma-delimited list of field(s), and using dynamic-SQL:
DECLARE	@SQL varchar(max)

SELECT	@SQL = 'select ' + field + ' from mstchvs'
FROM	fieldstatus
WHERE	flag = 0

EXEC(@SQL)

Assumes there are multiple rows that have flag = 0, field contains a single value; build a comma-delimited field-list for the dynamic SQL, and execute:
DECLARE	@SQL varchar(max)

SELECT	@SQL =	'select'
		+ Stuff((	SELECT ', ' + field AS [text()] 
				FROM	(	SELECT DISTINCT field
						FROM	fieldstatus
						WHERE	flag = 0
					) x
				For XML PATH ('')),1,1,'') 
		+ ' from mstchvs'

EXEC(@SQL)
