Question

I have the SQL below and want to update the managerNTID with @managerNTID only if the users DB record has StopManagerOverride value of 0, if it is set to 1 on the record then I don’t want to update this field:

UPDATE ee
SET 
    MangerId        = CASE ee.ShopManagerOverride
                            WHEN 0 THEN @MangerId
                            ELSE ee.MangerId
                          END
    ,ManagerNTID        = CASE ee.ShopManagerOverride
                            WHEN 0 THEN @managerNTID
                            ELSE ee.ManagerNTID
                          END
    ,NTID               = @NTID
    ,FirstName          = @FirstName
    ,LastName           = @LastName
    ,FullName           = @FullName
    ,ReportingGroup     = @ReportingGroup
    ,DistinguishedName  = @DistinguishedName
    ,IsActive           = 1
    --,StopManagerOverride= 1
    ,LastUpdate         = GETDATE()
    ,UpdateBy           = @UpdateBy
FROM dbo.Employees ee
    Inner Join dbo.Employees e ON e.NTID = ee.NTID
WHERE ee.NTID = @NTID

Thoughts on how to make this one field in the update have an inline condition?

edit: i am almost there, just need to resolve some ambiguous columns now. my eyes are red from this already.

You could try something like this – if the ShopManagerOverride is set to 1, update it to the parameter value passed in, otherwise update it to the value it already has (I’m also assuming your field is really ManagerId – not MangerId – right??):

UPDATE 
    dbo.Employees
SET 
    ManagerId = @ManagerId,
    ManagerNTID = CASE e.ShopManagerOverride
                     WHEN 1 THEN @managerNTID
                     ELSE e.ManagerNTID
                  END,
    NTID = @NTID,
    FirstName = @FirstName,
    LastName = @LastName,
    FullName = @FullName,
    ReportingGroup = @ReportingGroup,
    DistinguishedName = @DistinguishedName,
    IsActive = 1,
    LastUpdate = GETDATE(),
    UpdateBy = @UpdateBy
FROM
    dbo.Employees e 
WHERE 
    e.NTID = dbo.Employees.NTID
    AND dbo.Employees.NTID = @NTID

Untested, straight and “free hand” from my brain – hope I got the syntax right! Try it – does it work, does it do what you’re looking for??
