Discussion
We use the SQL construct COLUMNS(*) to determine the number and type of columns in a table.
Answer: B
Correct answer: False
There is no such SQL construct. The number and type of columns in a table are found by querying the system catalog or the information schema, or by using a product-specific command such as DESCRIBE or sp_columns. COUNT(*) does exist and counts rows, which is probably what the invented name is meant to echo.
