can someone please help to put the below query in the liquibase syntax:
delete from test_table t1
where exists (select emails from test_table t2
where t2.emails=t1.emails
and t2.rowid< t1.rowid);
----------

I think only way to achieve this is put it inside a sql tag
<sql >delete from test_table t1
where exists (select emails from test_table t2
where t2.emails=t1.emails
and t2.rowid< t1.rowid)
</sql>

I have this code:
SELECT
ZONE_NAME,
ORG_ID,
ORG_SHORT_NAME,
XMSSN_USE
FROM TABLEZ
;
UPDATE TABLEZ
SET TABLEZ.BILL_CYCLE = '1-DEC-2020 4' WHERE (SELECT TABLEZ.XMSSN_USE WHERE TABLEZ.XMSSN_USE=224)
But it doesn't seem to execute. What could be the problem?
You have 2 different query sentences. You should use ; after first query and then write the update query.
Also you need to use some field on the where clause, your where is empty.

You can double-check you're getting the right rows by commenting out the first line.
Here's an example with a procedure on db<>fiddle.

I have a table where the name is like "id,name" and I know the id portion and I need to get all the rows from the table by giving that id. The ID is always unique for the table. I've tried selecting the table out from information_schema.tables and I can get the table selected but then can't figure out how to get the data from it.
You're looking to use AS (alias):
SELECT test1.id AS id_test1, t2.id AS id_test2
FROM table1 AS test1
INNER JOIN table2 AS t2 ON (...)
