I need to include columns to an index after creating it. So I need to replace this command
CREATE INDEX
[INDEX01] ON [TABLE01] (Column01, Column02, Column03)
INCLUDE (Column04, Column05, Column06, Column07)
with
CREATE INDEX
[INDEX01] ON [TABLE01] (Column01, Column02, Column03)
and somehow include necessary columns after this command.
Could you help me, please?

You cannot change the columns in an index using an ALTER INDEX statement, so what you will have to do is:

DROP INDEX INDEX01

CREATE INDEX INDEX01 .. with the columns you wish the index had

I hoped I can make it without dropping.

Thanks for the answer.

Use ALTER INDEX to perform the following maintenance tasks for a Text index:

Rename the index.

Rebuild the index using different preferences. .

Resume a failed index operation (creation/optimization). .

Process DML in batch (synchronize). .

Optimize the index. .

Add stopwords to the index. .

Yes that is what I did. Recreated the indexes. Fortunately I don't have to do it too often so it's a good solution for me. Thanks.
