Hi,

Try like as follows....

SQL

SELECT T1.id,
    CASE WHEN (EXISTS (SELECT 1 FROM table2 WHERE ID=T1.ID AND companyid=1) AND
               EXISTS (SELECT 1 FROM table2 WHERE ID=T1.ID AND companyid<>1) ) THEN 'Both'
        WHEN (EXISTS (SELECT 1 FROM table2 WHERE ID=T1.ID AND companyid=1)) THEN 'C'
        WHEN (EXISTS (SELECT 1 FROM table2 WHERE ID=T1.ID AND companyid<>1)) THEN 'D'
    END
FROM table1 T1
