you use INNER JOIN on column DeptIdSELECT e.EmpId, e.Empname, d.DeptNameFROM Employee e INNER JOIN Department d ON e.DeptId = d.DeptId

| I dont want records. In the above example just to make reader understand my problem i had given a sample. In practical there may be 20-30 columns in my table. The output that i am expecting is just as EmpId EmpName DeptName (No records). |

| Hi. The output which i am looking should look like EmpId EmpName DeptName. thats it. Nothing more. The query should eliminate empid and manid because they are common in both the table. |
