This error message appears when you try to INSERT a row into a table and there are more columns in that table than you have supplied in the VALUES clause.
CREATE TABLE #t
, c2 INT
INSERT INTO #t (c1, c2) VALUES(1)
As you can see in the above example the table #t contains the column c1 and c2. In the INSERT statement which is intended to affect both columns c1 and c2, however, there is only 1 value supplied. In order to successfully run the INSERT statement, you need to correct either the column list or the VALUES list. Both must contain exactly the same number of arguments.
