T-SQL (SS2K8) :: Update With Case Statement Not Working?
May 29, 2014
I have a situation where I want to update a column if and only if it is null.
UPDATE Employee
SET VEmployeeID = CASE WHEN E.VEmployeeID IS NULL
THEN ves.VEmployeeID
END
FROM Employee E
INNER JOIN VEmployeeStaging VES
ON E.EID= VES.EID
But what happens is when I run the procedure every other time I run it, it changes everything to null. The other times it puts the VEmployeeID in.
So what is happening is the times when it is not null (where it is not supposed to do anything) it puts a null in. The next time it works.

I am using a PIVOT function to obtain the Invoice Values, but they appear in different currencies so need to perform a case function.
But am struggling with the syntax;
This fails a syntax check with
Msg 156, Level 15, State 1, Line 33
Incorrect syntax near the keyword 'Case'.
[Code]....

I am trying to use this logic into a query:
Select P.S,E.S,E.R
from Pack P(nolock)
join Exp E on P.Id=E.O
on E.R is null
case when E.R is not null then ''
else ''
end
where P.s='PLT000044'
I have to query two conditions joining the tables. when E.R is NULL and when E.R is not null. but the value is coming from the join between the 2 tables :P and E.

I have a population split between two vendors. One gets last names between A and R, the other the rest. Now, on a given date vendor 1 gets everybody.
I can accomplish this with a case statement on the upper range (R or Z), but it seems I should be able to do this without testing at all after the turnover date.
A small bit of the code:
declare @get_date datetime = convert(char(10),getdate(),101)
select top 10 pt.pt_id, pt.last_name
fromsmsmir.mir_acct a join smsmir.mir_pt pt on (a.src_sys_id = pt.src_sys_id
and a.pt_id = pt.pt_id
and a.from_file_ind = pt.from_file_ind
[Code] ....
Seems I should be able to not test the last name after the turnover date, but I can't figure out how.

I am a junior dba not a developer. So I'm just trying to get use to write code in T-SQL.
Anyways, I have a table which is dba.dbhakyedek.
Columns are
dbname, username, class_desc, object_name, permission_name, state_desc
I have statement
select case
when class_desc='OBJECT_OR_COLUMN' then 'GRANT '+permission_name+' ON '+'['+left(object_name,3)+'].'+'['+substring(object_name,5,len(object_name))+ '] TO '+username
WHEN class_desc='DATABASE_ROLE' THEN EXEC sp_addrolemember N'object_name', N'MC'
end
from dba.dbhakyedek
where username='MC'
This statement was running successfully until exec sp_addrolemember thing. I just learned that i can't call a sp in select case but i couldnt figure out how to do it.

I was given the task to come up with a result set based on certain criteria:
Please add one row for each offer code
1) Opt-in rate by offer code: This can be calculated by dividing XXX Inventory with lead / XXX Inventory (A)
The report should read something like below:
Example result set:
Log Date: OfferLetter OfferCode DailyCount
2014-07-20 A XXX Inventory (A) 108
2014-07-20 A XXX Inventory with lead 54
2014-07-20 A XXX Inventory Opt-in Rate: 50%
There are 12 different groupings and OfferLetter A is just one of them.
Below is the code that is written to date:
DECLARE @Start datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 8), 0)
DECLARE @End datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1) + 1, 0)
DECLARE @Today datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1), 0);
SELECTDT.OfferCode, DT.OfferCodeDesc
INTO#tempOfferCodes
[Code] ....
The issue I'm having is that the values I need to divide by are in fact, a result set from the CASE statement. It's been a long time since I've done anything like this.

I am trying to use a date comparison in a statement using the year statement as well. Here is what I have:
Case [LastHireDate]
When YEAR([LastHireDate]) < Year(@EndYearlyDate) then '12'
When Month([LastHireDate]) = '1' then '12'
When Month([LastHireDate]) = '2' then '11'
When Month([LastHireDate]) = '3' then '10'
When Month([LastHireDate]) = '4' then '9'
[Code] ....
When I am looking at it [LastHireDate] is showing that red line underneath. The < symbol has a red line and @EndYearlyDate has a red line. I can not seem to get them to clear and am, wondering what I am missing. When I execute the error comes up that it does not like the < sign in there.
Here is the full piece that the Case resides in:
Insert _Test
SELECT
EmpNo,
PersonIdNo,
REPLACE(PersonTaxIdNo,'-',''),
LastName,
FirstName,

i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END
What is the best way to script this

I would like to update a decimal column in a temporary table based ona set of Glcodes from another table. I search for a set of codes andthen want to sum the value for each row matching the Glcodes.

Hi,
I am trying to write an update query to update rows in one table.
Structure of Table1:
SocialSecurityNumber Varchar(9) -- Primary Key
Name Varchar(30)
Structure of Table2 :
SocialSecurityNumber Varchar(9)
Name Varchar(30)
Table 1 contains:
Row1: "123456789" Sally
Row2: "999999999" Bill
Row3: "333333333" Alex
Table 2 contains:
Row1: "123456789" <NULL>
Row2: "123456789" <NULL>
Basically I want to update the name column in Table 2 (based on the SocialSecurityNumber column) so that after
the update Table 2 will contain:
Row1: "123456789" Sally
Row2: "123456789" Sally
------------------------------------------------------------
First I tried:
UPDATE Table2
INNER JOIN Table1 ON Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
SET Table2.Name = Table1.Name
WHERE Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
This works in Access but not it SQL Server 7.0.
------------------------------------------------------------
Then I tried:
UPDATE Table2
INNER JOIN Table1 ON Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
SET Table2.Name = Table1.Name
Again this works in Access but not it SQL Server 7.0.
------------------------------------------------------------
Finally I tried:
UPDATE Table2, Table1
SET Table2.Name = Table1.Name
WHERE Table2.SocialSecurityNumber = Table1.SocialSecurityNumber
This also did not work.
------------------------------------------------------------
Is there any way to write this update statement without cursors?
Thanks.

I have the following update statement, which when executed, updates zero rows. However, if I replace the first two lines with a SELECT * , I will get records. Can somebody tell me why?
UPDATE [DW_DatamartDB]. [dbo].[FactLaborDollars]
SET [LaborBudget_USD] = Week1
FROM [DW_StagingDB].[ETL].[Transform_FactLaborBudget] BUDGET JOIN
[DW_StagingDB].[ETL].[Transform_FactLaborDollars] LABOR ON
Labor.Location_Code = Budget.Location_Code
JOIN [DW_DatamartDB]. [dbo].[DimDate] DATE ON
Date.FiscalWeekOfPeriod = Labor.FiscalWeekOfPeriod AND
Date.FiscalPeriodOfYear = Labor.FiscalPeriodOfYear
WHERE Labor.FiscalYear = CAST(SUBSTRING(DATE.Date_Code,1,4) AS NVARCHAR(50)) AND
Budget.FiscalYear = CAST(SUBSTRING(DATE.Date_Code,4,1) AS NVARCHAR(50)) AND

I've got the following update statement:
UPDATE ISSUE_ACTIONS
SET BAE_FLAG = 2
WHERE IA_ISSUE_NO = 399
AND IA_SEQUENCE = 20
The fields BAE_FLAG, IA_ISSUE_NO, and IA_SEQUENCE are all of the type int.
When I run this code inside of my windows app (C#),
cmd3.CommandText = "UPDATE ISSUE_ACTIONS " +
"SET BAE_FLAG = 2 " +
"WHERE IA_ISSUE_NO = 437 " +
"AND IA_SEQUENCE = 13";
try
{
cmd3.ExecuteNonQuery();
}
catch (Exception e)
{
throw (e);
}
I get a timeout error:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The statement has been terminated.
But when I run the SAME statement from Query Analyzer, it executes without a problem.
Has anyone run into this issue before? How do I get around this?
The CommandTimeout property of cmd3 is set to the default because this is not a complex query and should not take more than .5 seconds to execute.

Is it possible to use CASE statement with INSERT /UPDATE statement?this is what i am trying to do
i have a table like this
Field1 Field2 Field3 FieldType1 FieldType2 FieldType3
1-when there is no data for a given combination of Field2 and Field3,i need to do "insert".i.e the very first time and only time
2-Second time,when there is already a row created for a given combination of Field2 and Field3,i would do the update onwards from there on.
At a time value can be present for only one of the FieldType1,FieldType2,FieldType3) for insert or update
I am passing a parameter to the stored procedure,which needs to be evaluated and wud determine,which field out of (FieldType1,FieldType2,FieldType3)has a value for insert or update .this is what i am trying to do in a stored procedure
CREATE PROCEDURE dbo.StoredProcedure
( @intField1 int, @intField2 int, @intField3 int, @intFieldValue int , @evalFieldName varchar(4) )So i am trying something like
CaseWHEN @evalFieldName ="Fld1" THENINSERT INTO TABLE1 (Field2,Field3,fieldType1,FieldType2,FieldType3)values (@intField1,@intField2,@intField3,@intFieldValue,cast(null as int) fld2 ,cast(null as int) fld3)
CaseWHEN @evalFieldName ="Fld2" THENINSERT INTO TABLE1 (Field2,Field3,fieldType1,FieldType2,FieldType3)values (@intField1,@intField2,@intField3,cast(null as int) fld1 ,@intFieldValue,cast(null as int) fld3)
CaseWHEN @evalFieldName ="Fld3" THENINSERT INTO TABLE1 (Field2,Field3,fieldType1,FieldType2,FieldType3)values (@intField1,@intField2,@intField3,cast(null as int) fld1 ,cast(null as int) fld2,@intFieldValue)
END
similar trend needs to be followed for UPDATE as well..obiviousely its not working,gives me synatax error at case,when,then everywher.so can someone suggest me the alternative way?..i am trying to avoid writing stored procedure to insert/update for each individual fields..thanks a lot

I have used the below update query. However, its updating only the first value. Like its updating AB with volume when c.Type = ABC, similarly for CD. Its not updating based on the 2nd or the next case condition.
Â
Update XYZ Set AB = a.Amt * (CASE WHEN c.Type = 'ABC'Â THENÂ (c.volume)
 WHEN c.TYPE = 'DEF' THEN (c.volume)
 WHEN c.Type = 'GHI' THEN (c.volume)
 Else 0
 END),
 CD = CASE WHEN c.Type = 'MARGIN' THEN '4105.31'
 WHEN c.Type = 'ABC' THEN '123.1'
 WHEN c.Type = 'DEF' THEN '234.2'
WHEN c.Type = 'GHI' THEN '567.1'
END
 from table1 a join table2 b
 on a.Cust = b.Customer
 join table3 c
 on b.account = c.account and b.channel =c.channel
Why its not working properly? But if i use Select statement instead of update query its working properly.

I'm trying to generate an update statement based off select statement results. A very basic example,
SELECT ListID FROM DListing WHERE Status = 2Results return 3 rows.
1234
2345
3456
How can I take those results and turn them into WHERE criteria for UPDATE statement?
Generated UPDATE statement should look like this.
UPDATE DListing SET Status = 1 WHERE ListID IN (1234,2345,3456)
I have started by creating a temp table to hold my SELECT results, but I don't know how to get those results into format for IN condition. Right now I get 3 UPDATE statements with 1 ListID in each IN condition.
CREATE TABLE #TempStatusUpdate(ListID INT)
INSERT INTO #TempStatusUpdate
SELECT ListID FROM DListing WHERE Status = 2
SELECT 'UPDATE DListing SET Status = 1 WHERE ListID IN (' + CONVERT(VARCHAR(30),ListID) + ') AND Status = 2'
DROP TABLE #TempStatusUpdate

it posts and the page loads but the data is still the same in my datagrid. what could be wrong with this simple statement... i've tried testing the statement above with constant values of the correct type but i don't think that matters because the SqlCommand() accepts a string only anyways.. doesn't it?

I am trying to create a stored procedure that will take a text value passed from an application and update a table using the corresponding integer value using a CASE statement. I get the error: Incorrect syntax near the keyword 'SET' when I execute the creation of the SP. What am I missing here? This looks to me like it should work. Here is my code.

I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table
set target_column =
case
when source_column_1= 'ABC'then 'XYZ'
when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.

Only diff is SET clause and 1 Where condition.
So i am trying to combine 2 Update statements into 1 and trying to avoid visit to same table twice.

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
Thanks,
Jason

Hi All,
I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance.
My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code:
Insert into myTblA
(TblA_ID,
mycasefield =
case
when mycasefield = 1 then 99861
when mycasefield = 2 then 99862
when mycasefield = 3 then 99863
when mycasefield = 4 then 99864
when mycasefield = 5 then 99865
when mycasefield = 6 then 99866
when mycasefield = 7 then 99867
when mycasefield = 8 then 99868
when mycasefield = 9 then 99855
when mycasefield = 10 then 99839
end,
alt_min,
alt_max,
longitude,
latitude
(
Select MTB.LocationID
MTB.model_ID
MTB.elevation, --alt min
null, --alt max
MTB.longitude, --longitude
MTB.latitude --latitude
from MyTblB MTB
);
The error I'm getting is:
Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works.
I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.
