I need to move data from Intel_Data table into Intel_MainDataTable table into sql Server. I have following query

SQL

INSERT INTO Intel_MainDataTable 
    SELECT * 
    FROM Intel_Data
    WHERE Intel_MainDataTable.id != Intel_Data.id

C#

But this code gives errors, it says that Intel_MainDataTable.id donn't exists. Both Tables have same fields. They are identical. Who can help me to write correct this query ?

No it isn't working. It says: The multi-part identifier "Interl_MainDataTable.id" couldn't be found

Solution 2

Try:

INSERT INTO newtable
SELECT * FROM oldtable
WHERE oldtable.id not in
(select id from newtable)

Or

INSERT INTO newtable
SELECT * FROM oldtable
WHERE NOT EXISTS
(SELECT * from newtable where id=oldtable.id);
