Dec 7, 2004
I've this Stored procedure on a SQLserver 2000 SP3:
SELECT *,CASE immagine WHEN NULL THEN 0 ELSE 1 END AS hasImage
FROM Squadre WHERE squadra = @squadra
this is a flag that returns if the image field is present or not..
i've a lot of this type of stored procedures.. but this one returns me an error..
---------------------------
Microsoft SQL-DMO (ODBC SQLState: 42000)
---------------------------
Errore 306: The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
---------------------------
OK
---------------------------

When I created a CASE statement (This is at work, Pat:)) it is about 30-40 lines long. I gave it a name and set the name = to the case statement:
ie,
SELECT fieldname1 =
CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END
, fieldname2
, fieldname3
FROM tablename1
GROUP BY CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END, , fieldname2, fieldname3
etc.
The long CASE statement in my GROUP BY is awkward to me. Is this the only way to do it? I tried using the fieldname1 but it comes back as an invalid field name and asks for the "expression".
Regards,
Dave

I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.
Say I have a table called myTable with columns col1,col2,col3,
Here's what I'm trying to do
with myCTE AS
(
Select
col1
,col2
,col3
,row_number() over (order by
case when(@DIR = 'ASC') then
case when @COLTOSORTBY='col1' then col1 asc
when @COLTOSORTBY='col2' then col2 asc
else col3 asc
end
else
case when @COLTOSORTBY='col1' then col1 desc
when @COLTOSORTBY='col2' then col2 desc
else col3 desc
end
end
from myTable
)
Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.
Thanks.

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.

Hi all,
How do i execute a stored procedure in the THEN CLAUSE of my CASE STATEMENT? Av been getting errors since.
Here is my code:
Alter PROCEDURE sp_getTxn (
@m1 int = Null,
@txn int = Null,
@p2 int = Null,
@amt int = Null,
@pAccountno varchar(50) = 'Null',
@DAcct int = Null,
@Balance Decimal(19,4) = NULL OUTPUT,
@pBalance Decimal(19,4) = NULL OUTPUT,
@RowsReturned smallint = NULL OUTPUT )
AS
SET NOCOUNT ON
select CASE
WHEN @m1 = 200 THEN case
when @txn = 00 then ('exec dbo.CustOrderHist (@CrAcct int)')
when @txn = 01 then ('exec dbo.Sp_withdrawal')
when @txn = 31 then exec dbo.CheckBalance(@pAccountno varchar(50), @pBalance Decimal(19,4) OUTPUT)
when @txn = 38 then ('exec dbo.Sp_StatementOfAcct')
END
END
WHEN @m1 = 420 THEN case
when @txnType = 00 then ('exec dbo.Sp_reversal')
when @txnType = 01 then ('exec dbo.Sp_reversal2')
when @txnType = 31 then ('exec dbo.Sp_reversal3')
END
END
SET @Balance = @pBalance
Print @Balance
Or is there an alternative to the above CASE statement that is easier and faster?
Thanks

I have been trying to get the following Selects to work using a case expression in the order by section.
I know I can easily separate out the two statements but I want to do a select using the case statement below ;
however, I keep getting error 16 --"Order by items must appear in the select list if the statement contains a union.
If remove the case statement and put order by "internalID desc" I receive no errors. Moreover, when I take out the union statement and execute the two select statements with each including the case expression it runs as planned.
Can anyone tell what the problem is here? I have combed the web looking for an answer, but it seems that the statement is valid.
Thanks
J
declare @date
set @date = '2001'
select internalID from section_data_v3
union
select internalID from section_data_v4
order by
case when (@date = '2001') then internalID end desc

I am trying to write a Procedure in SQL 2005 that retreives a list of rows from the database. I pass to the procedure sorting parameters. This procedure works fine for all of the fields that I enter in the Order By, except for one.
The field that does not work is a varchar(500) field (named Description).
I am not sure what the problem is.
The error that I am getting is:

Hi,
I have a concern about adding a new field to a table with image field - which is huge.
Will there be a problem with some databases, where they have a hard time locating data correctly after such a large field?
Previously this happened to me, and what was advised to put all the big fields at the end of the table.
Thanks.

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

Is it possible to view this binary data.
I would like a default blank gif to be returned if no image is uploaded.

Dim bytesReceived As Long = DBContent.GetBytes(0, 0, Doc, 0, Doc.Length)
Dim encoding As ASCIIEncoding = New ASCIIEncoding

Hi,
does anyone know a way, using native SQL, to store a result of a query in an image field of a certain table.
The case is we have a selfmade replication to communicate with several SQL servers in stores, this replication is over a telephone line. So we collect all the data using SQL statements and store them in a separate table as an image field. This is done know through a Delphi application that streams the resultset to a image field.
Thanks in advance,

I am creating a document management systems using asp. I have beenresearching the different ways of handling the documents such as using thefile system and storing the path in the db, and actually storing thedocument in the db. I like the idea of storing it in the database muchbetter because I can allow users to manage documents themselves (I alreadyhave the code in place to do it if I decide), having a central system withthe ability to add my own document properties by adding fields to the table,security, and backups. I have found that most think it is better to storethe path due to performance issues and the rate the db can grow. I havelooked at our current system in access and we have a total of 4400 documents(of which probably 25% are in the database but don't actually exist anymorein the file system, one hangup about the file system) since 1988. Thiscomes to about 300 documents added each year. The other thing is the issuewith the size of the db. I don't see a whole lot of difference with thisissue because it is going to take up space in your file system too, althoughthe file system may be more efficient at storing them. I would say that 95%of our docs are under 1 mb in size and done in ms word.The last thing is using full-text search capabilities in SQL Server. I needto be able to search the contents of the field.Is there other issues around storing documents in the db to consider besidesthe above?
