I need to convert this select in a delete.

SELECT FROM [HEDIS_DATA].[dbo].[VISIT_IN] P1

INNER JOIN (SELECT * FROM [HEDIS_DATA].[dbo].[VISIT_IN]
) Pl1
ON Pl1.[CLAIM_ID]= SUBSTRING(P1.CLAIM_ID,CHARINDEX('R',P1.CLAIM_ID)+1,LEN(P1.CLAIM_ID))

WHERE LEFT(P1.[CLAIM_ID],1)='R'

please any help

Be sure to have a backup and then try this:

DELETE P1
FROM [HEDIS_DATA].[dbo].[VISIT_IN] P1
INNER JOIN (SELECT * FROM [HEDIS_DATA].[dbo].[VISIT_IN] ) Pl1
ON Pl1.[CLAIM_ID]= SUBSTRING(P1.CLAIM_ID,CHARINDEX('R',P1.CLAIM_ID)+1,LEN(P1.CLAIM_ID))
WHERE LEFT(P1.[CLAIM_ID],1)='R'

No, you're never too old to Yak'n'Roll if you're too young to die.

actually there's no need for derived table after inner join as you're anyways selecting all the columns from it

Yes, you're right - eagleeye

DELETE P1
FROM [HEDIS_DATA].[dbo].[VISIT_IN] P1
INNER JOIN [HEDIS_DATA].[dbo].[VISIT_IN] Pl1
ON Pl1.[CLAIM_ID]= SUBSTRING(P1.CLAIM_ID,CHARINDEX('R',P1.CLAIM_ID)+1,LEN(P1.CLAIM_ID))
WHERE LEFT(P1.[CLAIM_ID],1)='R'
