When using the Stream operator to load data into temporal tables, the temporal qualifiers, such as CURRENT VALIDTIME and SEQUENCED VALIDTIME, must precede the DML statements, as in the following example.
APPLY
('SEQUENCED VALIDTIME INSERT INTO <target table> ... ;')
TO OPERATOR (STREAM_OPERATOR)
SELECT * FROM OPERATOR (<producer operator>);
When using an atomic Upsert, the temporal qualifier must precede the UPDATE statement, not the INSERT statement, as in the following example.
APPLY
('SEQUENCED VALIDTIME UPDATE <target table> SET ... WHERE ... ;',
'INSERT INTO <target table> ... ;')
INSERT FOR MISSING UPDATE ROWS
TO OPERATOR (STREAM_OPERATOR)
SELECT * FROM OPERATOR (<producer operator>);
