Question

I have two tables, TableA and TableB

TableA has 9 fields
TableB has 7 fields

There are 2 fields (id and name) that are identical in both tables, is there a way to select ONLY these two fields from TableA and insert them into TableB?

I have looked at the INSERT INTO… SELECT method using this statement:

INSERT INTO TableB
SELECT id, name
FROM TableA
WHERE id = 1

But I get the following error:

#1136 - Column count doesn't match value count at row 1

I assume this error is not allowing me to insert only 2 fields into the table? If so, is there a way around this or an alternative method?

Thanks

Try:

INSERT INTO TableB(id, name)
SELECT id, name FROM TableA where id = 1;

One would have to assume that the column names in TableB match TableA otherwise you would need to put in the right names.
