it's unclear
if companyid=1 and companyid<>1 then there is no meaning to write this condition because it will always goes to false part...this cond. will never true

i have a customer a/c that will map with another table and pull the data but one column should be update like if it match with condition 1 the display value 1 , if it match with condition 2 then display with value2. if it satisfy with condition 1 and condition 2 then values 3

Aarti Meswania 6-May-13 6:14am

then you should use inner case statements
e.g.
select table1.id,
case when companyid=1 and CompanyId<>1 then 'c'
Else
case when companyid=1 then 'd'
else
'e'
end
end as flag
from table1 join table2 table1.id=table2.id

1. solution

SQL

SELECT t1.id, [flag] = CASE
    WHEN companyid=1 THEN 'c'
    WHEN companyid=2 THEN 'd'
    WHEN companyid=3 THEN 'e'
    WHEN companyid=4 THEN 'f'
    WHEN companyid=5 THEN 'g'
    ELSE 'h'END
FROM table1 AS t1 INNER JOIN table2 AS t2 ON t1.id=t2.id

2. solution:

SQL

SELECT T.* 
FROM (
    SELECT t1.id, 'c' AS [flag]
    FROM table1 AS t1 INNER JOIN table2 AS t2 ON t1.id=t2.id
    WHERE companyid = 1
    UNION ALL
    SELECT t1.id, 'd' AS [flag]
    FROM table1 AS t1 INNER JOIN table2 AS t2 ON t1.id=t2.id
    WHERE companyid <> 1 AND IntField=5
    UNION ALL
    SELECT t1.id, 'c' AS [flag]
    FROM table1 AS t1 INNER JOIN table2 AS t2 ON t1.id=t2.id
    WHERE companyid = 1 AND IntField=9 AND TextField='CP'
) AS T
