How do we do this in SS2k5?
in
EXEC(sqlstring)
sqlstring wants to pass back a resultset to the caller.
- Local temp tables are out of scope.
- Global temp table works but is a bad idea.
- Table variables not supported as OUTPUT parameters for EXEC.

I want to pass a database parm to enlarge the maxsize for around 500 databases. Here is the primary script:
--====================================
declare @stringData varchar(200),
@stringLog varchar(200),
@databaseName varchar(25),
@returnCodeSize int
select @databaseName = 'ABC'
select @stringData = 'alter database ' + @databaseName +
' modify file (name = ABC_Data, maxsize = 1500MB, FILEGROWTH = 10%)'
print @stringData
exec (@stringData)
It works in above way.
But it did not work if
I use @returnCodeSize =exec(@stringData)
how could I get a return code from this exec. I can't use cmdshell since it is not an external operating command.
thanks

Hello, I have been working around this issue, but couldn't yet find any solution.I have a stored procedure that calls a method to do a certain repetitive work.In this function, I have a dynamic query, which means, that I am concatinating commands to the query depending on the input of the function.for example, there is an input for a function called "Id"Inside the function, if Id = 111I need to add " and ID <> 1" and if Id has another value I need to add " and ID = c.ID" something like that.Now, inside the function, I need to return a value by executing the above @SQLString as follows:EXEC @SQLStringWhen I need is something likeEXEC @SQLString, @Total OutputReturn (@Total)Are there any ideas ?regards

Hello,
The SqlString variable; if a null value is assigned, will Value return the text null? Also, if I use another type such as SqlInt32, when I do ToString(), if the value is null, will it return the text null, so that it will work with a SQL string? I was wondering if that was the case.

I have the following query in sql 2005:
PROCEDURE [dbo].[uspInsert_Blob] (
@fName varchar(60),
@fType char(5),
@fID numeric(18, 0),
@bID char(3),
@fPath nvarchar(60)
)
as
DECLARE @QUERY VARCHAR(2000)
SET @QUERY = "INSERT INTO tblDocTable(FileName, FileType, ImportExportID, BuildingID, Document)
SELECT '"+@fName+"' AS FileName, '"+@fType+"' AS FileType, " + cast(@fID as nvarchar(18)) + " as ImportExportID, '"+@bID+"' AS BuildingID, * FROM OPENROWSET( BULK '" +@fPath+"' ,SINGLE_BLOB)
AS Document"
EXEC (@QUERY)
This puts some values including a pdf or .doc file into a table, tblDocTable.
Is it possible to change this so that I can get the values from a table rather than as parameters. The Query would be in the form of: insert into tblDocTable (a, b, c, d) select a,b,c,d from tblimportExport.
tblImportExport has the path for the document (DocPath) so I would subsitute that field, ie. DocPath, for the @fPath variable.
Otherwise I can see only doing a Fetch next from tblIportExport where I would put every field into a variable and then run this exec query on these. Thus looping thru every row in tblImportExport.
Any ideas how to do this?
Anyone know how to return a sql command from a sql server stored procedure using asp.net c# and sql server 2000?I'm trying to debug the stored proc and thought the easiest way would be to return the insert command and debug it in the query analyzer.Thanks.Doug.

If i have an SP called mySP that accepts one parameter @param
If I have a table of paramaters with only one column like this:
Param1
Param2
..
ParamN
How do I do if I want to execute the SP on all the table fields:
some thing like this:
Exec my SP 'Param1'
Exec mySP 'Param2'
...
Exec mySP 'ParamN'
I want that automatically since the parameters are going to be in a table called myTblParams
Notice that I don t want to pass all the parameters to the SP just once but only one value each time I execute the SP since mySP ccepts only one parameter.
Thanks a lot for guidelines
I like to use the table "Inserted" within exec(), but it doesn't work because the scope is different. Does anyone have some sort of solution to this problem?

Hi,
I'm trying to capture the value returned from sprocs. I stored the sproc name in the table and use cursor to run each sproc. Now the question is how can I capture and store the return value in a variable?
Here is the scenario:

count_A -- procedure, select count(*) from ...
count_B -- procedure, select count(*) from ...
count_C -- procedure, select count(*) from ...
here is my query:
----------------------------------------------------

DECLARE @count int
DECLARE cur CURSOR FOR
SELECT vchsprocname from table1
OPEN cur
FETCH NEXT FROM cur
into @vchsprocname
WHILE @@FETCH_STATUS = 0
BEGIN
exec @count = @vchsprocname -- I know I cannot do this, the vchsprocname cannot be variable. What else can I do?

Hi
I've used a temporary table in the stored procedure
I've created it as DECLARE @Temp TABLE (id INT)
in select clause I've used this temp table through the joins..
But I've also used a varchar variable to store my criteria...
which I'm building in the stored procedure
so inorder to use it in the where clause I used
EXEC ('SELECT ....................
FROM @Temp T
LEFT OUTER JOIN ...
LEFT OUTER JOIN ...
WHERE ' + @Criteria )
Unfortunately this is not working.
Giving the errror
Must declare the variable '@TempT'.
I had to use Temporary table using #, which I feel is really waste of memory...
Is there a way by which I can use my Table variable in the EXEC statement.
Thanks In advance

First, sorry about my poor english.
I have a database which above 6 gb data and i have droped all table in my database.
I try to restore from log file but my database is set to simple backup and auto shrink so log file doesn't help anymore.
I have used some software to recovery from log file too but useless.
My only hope right now is mdf file.
Please help me. How could i restore my mdf file to state before i droped tables.

I wanted to insert the result-set of a Exec(@sqlcommand) into a temp table. I can do that by using:
Insert into #temp
Exec(@sqlcommand)
For this to accomplish we need to define the table structure in advance. But am preparing a dynamic-sql command and storing that in variable @sqlcommand and the output changes for each query execution. So my question is how to insert/capture the result-set of Exec(@sqlcommand) into a temp table when we don't know the table structure.
I have a temporary table with multiple records and a Stored Procedure requiring a value. In a Stored Procedure, I want to loop through records in the table and use the value from each record read as input to another Stored Procedure. How do I do this?
View 7 Replies View RelatedHello,
Can anyone shed some light on why the following:
declare @str varchar(2000)
set @str = 'SELECT * INTO #TmpTable FROM FormHistory'
exec (@str)
SELECT * FROM #TmpTable
gives the following error:
Invalid object name '#TmpTable'.
This is a very cutdown version of what I am trying to achieve so it might not seem obvious why I am writing it into a string and using exec but in the real code I do need to do this. I have cut it right back to try to get to the bottom of why this doesn't work. I suspect the # in the string is causing the problems.
Thanks for any help

In working through some examples, sometimes I will see this pattern for receiving messages: What is the purpose of the "nested" WAITFOR (RECEIVE? What is this actually doing? Is it receiving the same message in both RECEIVE?
WAITFOR (
RECEIVE @dh = [conversation_handle],
@message_type = [message_type_name],
@message_body = CAST([message_body] AS NVARCHAR(4000))
FROM [Queue]), TIMEOUT 1000;
WHILE @dh IS NOT NULL
BEGIN
IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
BEGIN
RAISERROR (N'Received error %s from service [Target]', 10, 1, @message_body) WITH LOG;
END
END CONVERSATION @dh;
COMMIT;
SELECT @dh = NULL;
BEGIN TRANSACTION;
WAITFOR (
RECEIVE @dh = [conversation_handle],
@message_type = [message_type_name],
@message_body = CAST([message_body] AS NVARCHAR(4000))
FROM [Queue]), TIMEOUT 1000;
END
COMMIT;
Other times I will see this pattern for receiving messages: Why do a RECEIVE TOP(1) instead of just a RECEIVE?
WAITFOR(RECEIVE TOP(1)
@conversationHandle = conversation_handle,
@messageTypeName = message_type_name,
@messageBody = message_body
FROM [Queue]), TIMEOUT 1000;
And other times I will see this pattern for receiving messages: What is the purpose of RECEIVING into an in-memory table when you can just process the message directly?
WAITFOR(RECEIVE
queuing_order,
conversation_handle,
message_type_name,
message_body
FROM [Queue]
INTO @tableMessages), TIMEOUT 1000;
IF (@@ROWCOUNT = 0)
BEGIN
COMMIT;
BREAK;
END
What is the difference between the three approaches from an architectural and performance perspective? I need to process messages as fast as possible and I'm not sure why or when each should be used. Also, does the timeout have any impact on how FAST messages will be processed, or is it exactly what it says - a timeout - if a message is not found within the period then the procedure will break?
HI
I am trying to set up a stored procedure to retrieve to 20 messages from a queue into a table to implement a batched process. I have the following code in a stored procedure.
WAITFOR (
RECEIVE top (20) -- get batched so that we can process same listid once
message_type_name,
message_body, -- the message contents
conversation_handle -- the identifier of the dialog this message was received on
FROM dbo.target
into @PayloadData
), TIMEOUT 3000 -- if the queue is empty for three second, give UPDATE and go away
However, the stored procedure is only retrieving 1 message at a time from the queue. Did I miss some other setting

Hello Guys,
I really need you help to debug this query.
OBJECTIVE:THE QUERY SHOULD GIVE ME THE FIELDS I MENTIONED IN THE FIRST QUERY WITH THE CONDITIONS BELOW.
CONDITION 1: RateReview field should have yesterday's date
CONDITION 2: Email will be send to customer only once so Customer_GUID is UniqueIdentifier
CONDITION 3: Customer shouldnt' have opted to get out from receiving any email so Termination field should be NULL
ONe Customer can have many transwactions
Is there any way i write the code specifying that no email should be sent more than once evereven if customer buys 10 tickets.
Only one email sent so i need to specify that if this email has gone to particulare CUSTOMER_GUID then Ignore that record and
do not send any email. This would be done by some tool known as StrongMail.

View 1 Replies View RelatedI built a system where I am sending batches of messages using a single conversation. I want to pull these messages out of my queue using Service Broker. I may have more than one batch sitting in the queue waiting to be picked up, so....
In my SSIS package i started by getting a unique list of conversation_handles where the message type is my end of batch message ( should only be one per batch). Then I used the foreach loop construct thinking I could pass the conversation_handles around and into the data flow.
In the data flow I want to pull all of the messages at once. It looks like the receive statement is designed to do this with the concept of using a table variable.
So I built this SQL to use in for the SQL Command of my OLE DB Source. It gives me this error "Syntax error, permission violation, or other nonspecific errorr"
declare @messages table ( conversation_handle uniqueidentifier, message_type_name sysname, message_body xml );
receive conversation_handle, message_type_name, message_body
from dm.[consultant queue]
into @messages
where conversation_handle = ?
select conversation_handle, message_type_name, message_body
from @messages
If I change it to this, by removing the passed parameter and looking up what should be the same value that I am passing in then it works.
declare @ch uniqueidentifier;
declare @messages table ( conversation_handle uniqueidentifier, message_type_name sysname, message_body xml );
select top 1 @ch = conversation_handle
from dm.[consultant queue]
where message_type_name = 'BatchEnd'
order by queuing_order;

where conversation_handle = @ch
select conversation_handle, message_type_name, message_body

It just seems that SSIS, or OLE DB, don't want to pass parameters into a block of SQL that is executing this receive command. Has anyone else done something similar to what I am doing here? Any ideas on how to resolve this?
Obviously by using SSIS I want to work on the whole batch at once and not iterate message by message. Right now I just don't like the idea that I am getting the conversation_handle twice and possibly getting a different batch of messages to process.
Thanks!
I followed an example using the AdventureWorks database to set up a simple messaging test on one database:
Code Block
-- We will use adventure works as the sample database
USE AdventureWorks
GO
-- First, we need to create a message type. Note that our message type is
-- very simple and allowed any type of content
CREATE MESSAGE TYPE JobRequest
VALIDATION = NONE
GO
-- Once the message type has been created, we need to create a contract
-- that specifies who can send what types of messages
CREATE CONTRACT JobRequestor
(JobRequest SENT BY INITIATOR)
GO
-- The communication is between two endpoints. Thus, we need two queues to
-- hold messages
CREATE QUEUE RequestorQueue
CREATE QUEUE ReceiverQueue
GO
-- Create the required services and bind them to be above created queues
CREATE SERVICE Requestor
ON QUEUE RequestorQueue
CREATE SERVICE Receiver
ON QUEUE ReceiverQueue (JobRequestor)
GO
-- At this point, we can begin the conversation between the two services by
-- sending messages
DECLARE @conversationHandle UNIQUEIDENTIFIER
DECLARE @message NVARCHAR(100)
BEGIN
BEGIN TRANSACTION;
BEGIN DIALOG @conversationHandle
FROM SERVICE Requestor
TO SERVICE 'Receiver'
ON CONTRACT JobRequestor
WITH ENCRYPTION=OFF, LIFETIME= 600;
-- Send a message on the conversation
SET @message = N'Hello, World';
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE JobRequest (@message)
COMMIT TRANSACTION
END
GO
-- Receive a message from the queue
RECEIVE CONVERT(NVARCHAR(max), message_body) AS message
FROM ReceiverQueue
-- Cleanup
DROP SERVICE Sender
DROP SERVICE Receiver
DROP QUEUE SenderQueue
DROP QUEUE ReceiverQueue
DROP CONTRACT HelloContract
DROP MESSAGE TYPE HelloMessage
GO
This all works fine but if I run the section that creates the message and then copy the RECEIVE section to a new query window and execute it, nothing is returned. If I run the RECEIVE section within the same query window it returns the 'Hello World' message as expected. I am new to Service Broker and so am assuming that I am missing something obvious!!
