DISTINCT can be used with aggregates: COUNT, AVG, MAX, etc.
DISTINCT operates on a single column. DISTINCT for multiple columns is not supported.
Having clause is used to filter group.
The HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.
The HAVING clause is used to restrict the results returned by the GROUP BY clause.

Explanation:
Statement 1 (S1): SQL query SELECT count(distinct *) From EMP will generate error:
- The statement is false because the correct syntax for counting distinct values in SQL is "SELECT count(distinct column_name) FROM table_name". Using "*" as a parameter for the distinct keyword will not generate an error but may not provide the desired result.
Statement 2 (S2): 'Having' clause is used to filter groups:
- The statement is true. The HAVING clause is used in SQL along with the GROUP BY clause to filter groups based on a specified condition. It is used to apply a filter to the result set after the grouping has been done.
Therefore, the correct mapping for the statements would be:
- a) TF
- b) FF
- c) FT
- d) TT
The correct answer is option 'D' as both statements are evaluated individually as true and false respectively.
