Case When Conditions
Oct 14, 2014
I have the following:
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 THEN A2.ValStr END) AS TYPE_DOCUMENT
This works not perfect. In many cases I have more then one row and my query takes the max value of column Valstr. Thats is not exactly what I want. I'd like to have the value of Column Valstr of the row where column Vernum has the maximum value.
I've tried many things like:
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 AND A2.Vernum=test THEN A2.ValStr END) AS TYPE_DOCUMENT
OR
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 AND A2.Vernum=MAX(A2.Vernum) THEN A2.ValStr END) AS TYPE_DOCUMENT

I need to update many rows in some table. I've made such SQL query:
UPDATE [%TableName%]
SET [%FieldName%] = CASE
WHEN ID = 1 THEN '1'
WHEN ID =2 THEN '2'
....
END;
[%FieldName2%] = CASE
WHEN ID = 1 THEN '1'
WHEN ID = 2 THEN '2'
....
END;
WHERE ID IN {1, 2, ...}
Are there some limitations for CASE operator? How many "when - then" conditions can I include in query?

My question is fairly simple. When I join between two tables, I always use the ON syntax. For example:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
No problems there. However, if I then decide to further filter the selection based on some trait of the UserRole, I have two options: I can add the condition as a WHERE statement, or I can add the condition within the ON block.
--Version 1:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
WHERE
UserRoles.Active = 'TRUE'
-- Version 2
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId
AND UserRoles.Active = 'TRUE')
So, the question is, which is faster/better, if either? The Query Analyzer shows the two queries have the exact same execution plan, which makes sense, since they're both joining the same tables. However, I'm wondering if adding the condition in the ON statement results in fewer rows the JOIN statement initially needs to join up, thus reducing the overall initial size of the results table before the WHERE conditions are applied.
So is there a difference, performance wise? I imagine that if Users had a thousand records, and UserRoles had 10 records, then the JOIN would create a cartesian product of the two tables, resulting in 10,000 records in the table before the WHERE conditions are applied. However, if only three of the UserRoles is set to Active, would that mean that the resulting table, before applying WHERE conditions, would only contain 3000 records?
Thanks for whatever information you can provide.

How can I change my T-SQL text editor from text sensitive to text insensitive?

Jan 6, 2005
Hello:
I have created an SQL server table in the past on a server that was all case sensative. Over time I found out that switching to a server that is not case sensative still caused my data to become case sensative. I read an article that said you should rebuild your master database then re-create your tables. So after rebuilding the master database, a basic restore would not be sufficient? I would have to go and manually re-create every single table again?
Any suggestions?

We need to install CI database on CS server, and there are some issueswith stored procedures.Database works and have CI collation (Polish_CI_AS). Server hascoresponding CS collation (Polish_CS_AS). Most queries and proceduresworks but some does not :-(We have table Customer which contains field CustomerID.Query "SELECT CUSTOMERID FROM CUSTOMER" works OK regardless ofcharacter case (we have table Customer not CUSTOMER)Following TSQL generate error message that must declare variable @id(in lowercase)DECLARE @ID INT (here @ID in uppercase)SELECT @id=CustomerID FROM Customer WHERE .... (here @id in lowercase)I know @ID is not equal to @id in CS, but database is CI and tablenames Customer and CUSTOMER both works. This does not work forvariables.I suppose it is tempdb collation problem (CS like a server collationis). I tried a property "Identifier Case Sensitivity" for myconnection, but it is read only and have value 8 (Mixed) by default -this is OK I think.DO I MISS SOMETHING ????

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

I have a table
CREATE TABLE [dbo].[CmnLanguage]( [Id] [char](2) NOT NULL CONSTRAINT PkCmnLanguage_Id PRIMARY KEY, [EnglishName] [varchar](26) NOT NULL, [NativeName] [nvarchar](26) NOT NULL, [DirectionType] [smallint] NOT NULL, [IsVisible] [bit] NOT NULL, [CreatedDateTime] [datetime] NOT NULL DEFAULT GETDATE(), [ModifiedDateTime] [datetime] NULL)
We will use these 3 queries
select * from CmnLanguage where IsVisible = 0select * from CmnLanguage where IsVisible = 1select * from CmnLanguage
I want to make a method which handles these queries.
But at the back end on Stored Procedures
We have to write 3 queries
Which I don't want to do.
I want to minimize the queries and conditions
and want to just write one for these 3
Can any one do it?

Folks,
I'm having some real problems using the OR condition in a very simple SQL statement and could use your help or insight on where the problem lies, or perhaps a workaround.
I have a large flat table in a SQL 7 database with 10 million + records called "HISTORY". I have not installed either service pack 1 or 2. I'm attempting to run a query that references the following four fields which are all non-clustered keys:
EQUIPMENT_NO TEXT 12
CHASSIS_IN TEXT 12
CHASSIS TEXT 12
SVC_DATE_TIME SMALLDATETIME
Here's the SQL statement:
SELECT * FROM HISTORY WHERE (HISTORY.EQUIPMENT_NO = 'XYZ123' OR HISTORY.CHASSIS = 'XYZ123' OR HISTORY.CHASSIS_IN = 'XYZ123') AND SVC_DATE_TIME >= '01/15/00 00:00:00 AM' AND SVC_DATE_TIME <= '02/28/00 23:59:59 PM'
ORDER BY EQUIPMENT_NO
This query takes 11 min. 5 sec. inder the Query Analyzer and ultimately returns the 31 desired records.
If you remove the SVC_DATE_TIME criteria, about 350 records are returned in a matter of seconds. I've also tried variations on the date syntax such as '01/15/00', etc. with no change in the amount of time to execute.
Other queries such as a simple AND condition combining EQUIPMENT_NO and SVC_DATE_TIME are snappy.
Are there known problems/bugs with "OR" conditions in queries that anyone is aware of, particularly with parentheses; am I composing this query incorrectly? Is there some alternate syntax that would work as expected? I can't see where the query shouldn't execute quickly as expected, particularly with all indexed fields involved. I'm stumped! Lend me your expertise. Thanks much.

Hai frns small help needed.
I have a table called sample and i have the following requirement. i.e i need sum(credit) group by ssn no.
One special condition is as follows:
For each distinct ssn if "flag" has the same CX value,then out of all the records with the same CX value, the highest "credit" value is added to the sum for that "ssn" and the rest are ignored.
If while adding "credit" to the sum and if "credit" value is equal to zero then "sum" value is used for summing else "credit" value is used.
Can any one help me out in trying this logic. I have tried but i could'nt able embed the conditions inbetween the Sql statetment.
Here is the query is used
select * from sample
idssncreditflagsem
11010C90
21014C93
31014.5C92
41013.5C11
51024.2C33
61030C12
select ssn,flag,sum(case credit when 0 then sem else credit end) as sum from sam2
group by ssn,flag
ssn flag sum_val
101C13.5
103C12.0
102C34.2
101C98.5
The above output is wrong one.
Expected output
101 4.5+3.5=8.0
102 4.2
103 2.0
Any help would be appreciated
Regards,

-- Prepare test data
CREATE TABLE #table

How can I compare dates with conditions. I only want to Mark C where the difference between adm_datetime and prevsep_datetime is <= 1 otherwise E as well
where datediff(MINUTE,tg.adm_datetime,tg.pre_sep_date)< =1 ??
is it correct ? where should I put this to implement correctly ?

1. Are stored procedures WITH ENCRYPTION slower than the ones withoutencryption?2. Should i put most restrictive conditions first or last in WHERE? Inwhich order does MSSQL execute conditions? Or MSSQL determents whatwould be best and does not bother with the way i sorted conditions?for example:SELECT *FROM [users]WHERE[user_id] = 1 AND[baned] = 0Is "[user_id] = 1" or "[baned] = 0" going to be executed first?

I am trying to do a select with the closest match.
Code Snippet
CREATE TABLE [#Person]
(
[PersonId] tinyint IDENTITY(1,1) NOT NULL
,[Height] char(2) NOT NULL
,[Weight] char(3) NOT NULL
,[Age] varchar(3) NOT NULL
,[HairColor] varchar(7) NOT NULL
,[EyeColor] varchar(7) NOT NULL
);
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('71', '150', '23', 'Brown', 'Blue');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('70', '190', '22', 'Blonde', 'Brown');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('69', '140', '20', 'Black', 'Brown');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('65', '150', '21', 'Brown', 'Green');
SELECT * FROM [#Person]
WHERE
([Height] > '66' AND [Height] < '72')
AND ([Weight] > '150' OR [Weight] < '180')
AND ([Age] > '20' OR [Age] < '25')
AND ([HairColor] IN ('Brown', 'Blonde', 'Black'))
AND ([EyeColor] IN ('Blue', 'Brown', 'Green'));
DROP TABLE [#Person];
This simple example works great. But what if I wanted everybody who met 4 of the 5 conditions? I tried to think of a counting solutions, and then order by the count but I could quite get there. Any help would be greatly appreciated. My live data is actual sales records with 20 some odd record types. I am hoping any solutions I find will scale well.

Hi,
I want to create a trigger that that is invoked when a certain condition is fulfilled. For instance:
I have 2 tables, PS and US with similar table structure. PS table contains a column called 'status'. Whenever the status column is updated from 2 to either 23, 24, 25 or 26, a new row, which contains the same data within the updated row of PS, will be inserted into the table US.
Can this be done? Thanks in advance.

Every time you visit a forum, the viewcount is changed, therefore raising the trigger and dropping my cache object. How do i make it so that the trigger is only fired if I update the Title or Description field? ALTER TRIGGER [dbo].[sp_Forums_Topics_AspNet_SqlCacheNotification_Trigger] ON [dbo].[sp_Forums_Topics] FOR INSERT, UPDATE,DELETE AS BEGINSET NOCOUNT ONEXEC dbo.AspNet_SqlCacheUpdateChangeIdStoredProcedure N'sp_Forums_Topics'
END

I can't figure this out for the life of me. Wanted to know if it's possible to select certain date conditions in a query, then later reference those conditions and to only select the max of them.
I need to do this dynamically as I do not know what the max value is. I've provided an example below:
Select var1
From table1
where
(
(Date1 = '11/30/2005')
OR
(Date1 = '12/31/2005')
)
and Date1 = (Max of previously selected values e.g. '12/31/2005')
What I can't figure out is how to dynamically retrieve the max of 11/31/2005 and 12/31/2005. Any ideas are greatly appreciated.

I have an issue accumulating a value based on certain conditions:
I need to sum up the days column as you can see table below. The sum is based on the StartNewFlag.
When the flag is 1, I need to start a new sum from zero, else I need to accumulate to the previous rows.
CREATE TABLE #foo
(
ItemID int,
StartDate datetime,
EndDate datetime,
StartNewFlag bit,
[Code] ....
My Results must look like one of the following tables (either one would work, however the second one is preferred)
Result 1:
ItemID StartDate EndDate StartNewFlag Days TotalDays
1 2015-07-01 00:00:00.000 2015-07-05 00:00:00.000 1 4 5
1 2015-07-08 00:00:00.000 2015-07-09 00:00:00.000 0 1 5
1 2015-07-11 00:00:00.000 2015-07-15 00:00:00.000 1 4 11
1 2015-07-18 00:00:00.000 2015-07-21 00:00:00.000 0 3 11
1 2015-07-22 00:00:00.000 2015-07-26 00:00:00.000 0 4 11
OR
Result 2:
ItemID EndDate TotalDays
1 2015-07-09 00:00:00.000 5
1 2015-07-26 00:00:00.000 11

I have a table where when an employee works LEAVE1 and LEAVE2 paycodes on the same day then in the new column called 'FLAG' we need to put a 1 for LEAVE1 and a 2 for LEAVE2, when these paycodes are not there on the same day then flag will be NULL as for other paycodes.
Tried using the CASE statements but it always puts a 1 or 2 for the respective paycodes regardless of the fact whether they were together on the same day or not.
WITH SampleData (PERSON,TRANSACTDATE, STARTDATE, END_DATE, IN_PUNCH,OUT_PUNCH,HOURS, PAYCODE) AS
(
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '06:00','09:00','3', 'REG1' UNION ALL
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '09:00','13:00','4','REG2' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '09:00','13:00','4','LEAVE1' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '14:00','16:00','2', 'LEAVE2'UNION ALL
SELECT 1234,'08/05/2015','08/05/2015','08/05/2015', '08:00','09:00','1', 'LEAVE1'UNION ALL
SELECT 4553,'08/05/2015','08/05/2015','08/05/2015', '08:00','09:00','1', 'REG1'UNION ALL
SELECT 4553,'08/05/2015','08/05/2015','08/05/2015', '10:00','12:00','2','LEAVE2'
)
