I have a query that is:
SELECT DISTINCT DepotIo.Depot2Guid AS Depot1Guid, Depot2.Title, NULL AS Depot2Guid
FROM DepotIo
JOIN DepotIoDetail ON DepotIo.Guid = DepotIoDetail.DepotIoGuid
JOIN dbo.GetUserDepot(#UserGuid) AS Depot2 ON DepotIo.Depot2Guid = Depot2.Guid
JOIN Item ON Item.Guid = DepotIoDetail.ItemGuid
WHERE DepotIo.Company = #Company AND (DepotIo.Branch = #Branch)
But I want to when #Branch is not null, comes to WHERE condintion part and when it's value is null, relinquish it.. Like this :
WHERE DepotIo.Company = #Company AND (CASE #Branch
WHEN IS NOT NULL THEN DepotIo.Branch = #Branch)
what's true command ??
This is usually handled using or:
WHERE DepotIo.Company = #Company AND
(DepotIo.Branch = #Branch OR #Branch IS NULL)
You can use CASE WHEN as follows:
(CASE WHEN #Branch IS NOT NULL
THEN CASE WHEN DepotIo.Branch = #Branch THEN 1 ELSE 0 END
ELSE 1 END = 1)
Cheers!!
If I understand the question, this should do it.
If DeDepotIo.Branch is not nullable. This will relinquish rows where #Branch<>DeDepotIo.Branch, but not when #Branch is NULL.
WHERE DepotIo.Company = #Company AND (ISNULL(#Branch, DeDepotIo.Branch) = DeDepotIo.Branch)

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);
I'm working on a stored procedure that is a select query. Under the WHERE clause I am filtering the return results to return only if there is a PageTitle= 'STA'
Here is am example of my query :
#InputCountryId INT,
#InputIndustryId INT
AS
BEGIN
SELECT
r.IdCountry,
r.IdIndustry,
r.PageTitle,
r.IndustryName
From dbo.Reports r
WHERE
r.IdCountry = #InputCountryId
r.IdIndustry = #InputIndustryId
r.PageTitle = 'STA'
END
The ending condition r.PageTitle I would like it to be applied ONLY IF InputCountry = 1 if not; do not include the filter.
I've attempted this by including a CASE. I am having a syntax error any time I try and introduce this case. Is this something that is possible? Am I implementing it incorrectly?
Here is an example of the stored proc with the CASE included.
#InputCountryId INT,
#InputIndustryId INT
AS
BEGIN
SELECT
r.IdCountry,
r.IdIndustry,
r.PageTitle,
r.IndustryName
From dbo.Reports r
WHERE
r.IdCountry = #InputCountryId
r.IdIndustry = #InputIndustryId
CASE WHEN #InputCountryId = 1 THEN
r.PageTitle = 'STA'
END
END
Try it this way:
WHERE
r.IdCountry = #InputCountryId and
r.IdIndustry = #InputIndustryId and
(#InputCountryId <> 1 or r.PageTitle = 'STA')
You dont need case statement. You can use OR clause
WHERE
r.IdCountry = #InputCountryId
r.IdIndustry = #InputIndustryId
(#InputCountryId != 1 OR r.PageTitle = 'STA')
this only filters PageTitle with STA when InputCountry is 1
I can't test with your data, but here is a CASE in a WHERE clause that works.
DECLARE #Variable INT = 3
SELECT GETDATE()
WHERE 1 =
CASE
WHEN #Variable = 1 THEN 1
WHEN #Variable = 3 THEN 1
WHEN #Variable = 5 THEN 1
ELSE 0
END
I'm new in sql server and I have WHERE clause like this:
WHERE[D].[IsLocked] = 0
AND(#StartDate IS NULL OR ISNULL([TA].[ModifiedDate], [TA].[CreationDate]) >= #StartDate)
AND(#EndDate IS NULL OR ISNULL([TA].[ModifiedDate], [TA].[CreationDate]) <= #EndDate)
AND((CASE WHEN[T].[TaskStatusId] = '09E02513-00AD-49E3-B442-A9ED2833FB25'
THEN 1 ELSE 0 END) = #Completed)
AND((#FilterEmpKey IS NULL AND[TA].[EmpKey] = #CurrentEmpKey)
OR (ISNULL([TA].[ModifiedAssignedBy], [TA].[AssignatedBy]) = #FilterEmpKey
AND[TA].[EmpKey] = #CurrentEmpKey))
But now I want to add if conditional in order to add more filters at the end of query like:
IF(#FilterEmpGuid IS NOT NULL)
AND[TA].[EmpKey] = #CurrentEmpKey
AND[TA].[AssignatedBy] = #CurrentEmpKey
AND[TA].[EmpKey] = #FilterEmpKey
But I get:
The multi-part identifier [TA].[EmpKey] could not be bound
What am I doing wrong?
IF conditionals are only for use outside sql queries, such as in procedures etc.
In a query itself you are limited to AND, OR and CASE statements, so you will need to rewrite your IF conditional for this:
AND (#FilterEmpGuid IS NULL
OR (
[TA].[EmpKey] = #CurrentEmpKey
AND[TA].[AssignatedBy] = #CurrentEmpKey
AND[TA].[EmpKey] = #FilterEmpKey
))
You could move the additional filter options into a scalar function.
If you know the additional fields that may be filtered, you may be able to get away with something like:
CREATE FUNCTION dbo.ExtendFilter(
#column_value VARCHAR(50), #param_value VARCHAR(50)
)
RETURNS BIT
AS
BEGIN
DECLARE #return BIT = 1; -- default RETURN to 1 ( include ).
IF ( NULLIF( #param_value, '' ) IS NOT NULL )
BEGIN
-- compare the column's value to the param value
IF ( #column_value <> #param_value )
SET #return = 0; -- don't include this record.
END
RETURN #return;
END
GO
And then use it like:
WHERE
{ other WHERE stuff }
AND dbo.ExtendFilter( [TA].[EmpKey], #CurrentEmpKey ) = 1
AND dbo.ExtendFilter( [TA].[AssignatedBy], #CurrentEmpKey ) = 1
AND dbo.ExtendFilter( [TA].[EmpKey], #FilterEmpKey ) = 1
Mind you this is just an example. You'd want to check #pram_value for NULL, etc...

And I keep getting the error
Column 'Users.EnglishName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Please help!
Like the message states, you need to group by the EnglishName column unless it is used in an aggregate function(Max or sum or likewise).
The issue is evident from your error message. Use GROUP BY in case of aggregate functions.
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
