SQL Server error 120 occurs when you don’t specify enough columns in your INSERT list when using a SELECT list for the values to insert.
It happens when you use a SELECT list in your INSERT statement, but the SELECT list doesn’t return as many columns as you’re specifying with the INSERT.
This is easy to fix. Simply make sure the number of columns match between your INSERT and SELECT list.
Here is the example of the code that cause the error.
INSERT INTO OrdersLatest ( OrderId,OrderDate,OrderDesc ) SELECT OrderId,OrderDate FROM OrdersMarch;
Output:

You can fix this by correcting it.
INSERT INTO OrdersLatest ( OrderId,OrderDate,OrderDesc ) SELECT OrderId,OrderDate,OrderDesc FROM OrdersMarch;
You can use less columns this would depend on whether or not we have any NOT NULL constraints on the destination table.
