The table structure is like this;
 slp_no  doc_type    clearing Date          ui               batch_no

 So for my result set I would want                
                 
  slp_no  doc_type    clearing_Date             ui            batch_no

   1       3        2021-03-25  2021032571350010008500002     7135001-000850

What I have tried:

SELECT * FROM IMG_PDC_OUTWARDCLEARING AS T1
WHERE 1=1 AND 
(BATCH_NO = '7135001-000850') AND (CLEARING_DATE = '2021-03-25') 
UNION
SELECT *
FROM IMG_PDC_OUTWARDCLEARING AS T2
WHERE 1=1 
AND (BATCH_NO = '7135001-000850') 
AND (DOC_TYPE = '2')

That SQL doesn't look like you thought too much before writing it: why does it include "WHERE 1=1 AND ..." given that it will always resolve to TRUE?

Where is the BATCH_NO? It doesn't appear in the table data you show at all.

Same thing for CLEARING_DATE?

How do you expect your IN condition to work at all, when it returns every column from the matching rows of the same table?

Stop guessing, think about your actual data - and I'm going to assume it doesn't look like your sample data because of the questions above - and think about what actually decides which rows you should return.
We have no idea what you are trying to do, but it's possible that you need to look at the DISTINCT keyword: SQL SELECT DISTINCT Statement[^] - but at the moment, we can't help you based on what you have given us.
