Answer:

True

Explanation:

Subquery can not return more than one (multiple) column, because the output can be compared with one column.

For example;

  • SELECT * From Table1 WHERE Column1 IN (SELECT ColumnA FROM Table2)

is a correct statement where

  • SELECT * From Table1 WHERE Column1 IN (SELECT ColumnA,ColumnB FROM Table2)

gives an error.
