An introduction to a conditional grouping clause in the SELECT statement.

A HAVING clause is valid when coded as part of a seed statement.

HAVING is never valid when coded as part of a recursive statement.

See Teradata Vantage™ - SQL Data Manipulation Language, B035-1146 for complete documentation of the HAVING clause.

having_condition
one or more conditional Boolean expressions that must be satisfied by the results groups.
You can use aggregate operators in a HAVING condition.
You cannot specify a SAMPLE clause within a subquery predicate within a HAVING clause.
You cannot specify BLOB, CLOB, UDT, or Period columns in the HAVING condition.
HAVING condition filters rows from a single group defined in the select expression list that has only aggregate results, or it selects rows from the group or groups defined in a GROUP BY clause.
