Only Update Table if Field is NULL - sql

I have this query which is working OK
UPDATE Master
SET Closed = Date(),
Status = 'Closed',
[Closure Reason] = 'Not on Extract'
WHERE NOT EXISTS ( SELECT 1
FROM Extract
WHERE Master.Case = Extract.Case
);
I need to amend it to add another criteria, ie ONLY do the update if the value of Master.[Closure Reason] is NULL
But this gives a syntax error:
UPDATE Master SET Closed = Date(), Status = 'Closed', [Closure Reason] = 'Not on Extract'
WHERE [Closure Reason] = "" AND
WHERE NOT EXISTS (SELECT 1
FROM Extract
WHERE Master.Case = Extract.Case
);
I've tried using IS NULL rather than = "" to no avail.
What is wrong with it please?


UPDATE Master SET Closed = Date(), Status = 'Closed', [Closure Reason] = 'Not on Extract'
WHERE [Closure Reason] IS NULL
AND NOT EXISTS (SELECT 1
FROM Extract
WHERE Master.Case = Extract.Case
);
You can't add multiple WHERE clauses, you need to use the AND. If your requirement is "ONLY do the update if the value of Master.[Closure Reason] is NULL", then check for NULL, not for an empty string.


You need to remove the second where before not exists.
UPDATE Master SET Closed = Date(), Status = 'Closed', [Closure Reason] = 'Not on Extract'
WHERE [Closure Reason] = "" AND
NOT EXISTS (SELECT 1
FROM Extract
WHERE Master.Case = Extract.Case
);


You need to add a AND conditional operator instead of having two WHERE clauses like
WHERE NOT EXISTS (SELECT 1
FROM Extract
WHERE Master.Case = Extract.Case
)
AND [Closure Reason] IS NULL;

SQL Where clause based on Status

Declare #Status nvarchar(25) = Null
Select * From Products
Where Type = 1
And
If Status is null, Don't add clause(means return all)
If Status = 'C', Add Status = 'Completed'
If Status = 'U', Add Status = 'Uncompleted'
How can I do this?

Don't call your variable the same as your column
Declare #MyStatus nvarchar(25) = Null
Select * From Products
Where Type = 1
AND (
(MyStatus is null)
OR (MyStatus = 'C' AND Status = 'Completed')
OR (MyStatus = 'U' AND Status = 'Uncompleted')
)

It would be better to simply assign the desired value to your #Status variable then you can simply check for equality -
where Type = 1 and (#status = status or #Status is null);

Your Merge Statement looks correct. This error is mostly seen in Azure Synapse. Make sure your target table is hash distributed to avoid this error.

Query to get worksheet manager hierarchy for a parameter in BI-publisher

The parameter has two values direct reports and indirect report.
I have tried:

Subquery returned more than 1 value. Update Select Minus

I have the following update scrpit..
UPDATE LIMRA_Retail_Current
SET AnnualizedWOExcessPremium = (SELECT
ISNULL(ul.AnnualizedWOExcessPremium, 0)-
isnull((select iul.AnnualizedWOExcessPremium
from dbo.LIMRA_Retail_Current iul
where ul.Distribution = iul.distribution
and ul.company = iul.company
and ul.Year = iul.year
and ul.Quarter = iul.quarter
and iul.Market = 'Retail'
and replace(ul.Product, 'Universal Life', 'Index Universal Life') = iul.product
),0) UL_MINUS_IUL
FROM dbo.LIMRA_Retail_Current UL
WHERE ul.Product like 'Universal Life%'
AND ul.Market = 'Retail')
How can I update the column AnnualizedWOExcessPremium using ALL the values of UL_MINUS_IUL. I want to use ALL the values in my update.

Looks like your sub select just needs a SUM:
(SELECT
SUM(ISNULL(ul.AnnualizedWOExcessPremium, 0)- isnull((select iul.AnnualizedWOExcessPremium )
from dbo.LIMRA_Retail_Current iul
where ul.Distribution = iul.distribution
and ul.company = iul.company
and ul.Year = iul.year
and ul.Quarter = iul.quarter
and iul.Market = 'Retail'
and replace(ul.Product, 'Universal Life', 'Index Universal Life') = iul.product
),0) UL_MINUS_IUL

How to assign a NULL value with a CASE statement?

I'm trying to assign a NULL value when another field is NULL using a CASE statement.
So far this is what I got:
UPDATE PunchintervalFinal
SET INDTTIME_LUNCH = (SELECT CASE
WHEN PunchintervalFinal.INDTTIME2 IS NULL THEN
NULL
END
FROM PUNCHBRIDGE A
WHERE A.EMPLOYEE = PunchintervalFinal.EMPLOYEE
AND A.PUNCHDATE = PunchintervalFinal.PUNCHDATE
AND PunchintervalFinal.EMPLOYEE = '500018')

This should do what you are trying to do:
UPDATE PunchintervalFinal
SET INDTTIME_LUNCH = NULL
FROM PunchintervalFinal
INNER JOIN PUNCHBRIDGE A ON A.EMPLOYEE = PunchintervalFinal.EMPLOYEE
WHERE PunchintervalFinal.EMPLOYEE = '500018'
AND A.PUNCHDATE = PunchintervalFinal.PUNCHDATE
AND PunchintervalFinal.INDTTIME2 IS NULL
