Have you looked at using OPENQUERY or OPENROWSET to access remote data via Linked Servers? This is fast and easy for small volumes of data.

If you’re talking large volumes of data it may be faster (and much easier on the indexes of your destination server) if you use BCP.EXE to dump the data from your source servers in “native format”, transfer it with ftp/scp/rsync, and then BULK INSERT/BCP.EXE to read it back in on the destination server. This is how I used to move millions of rows of IP traffic flows between servers.

Good luck.

Hi Hitech,

The exec() statement does not work that way. When using exec() with brackets it will not return a scalar value, unlike “exec @Result = someStoredProcedure”

You can still use the result set than comes back from exec(), though, like this:

declare @sqlStr nvarchar(max)
declare @myVar varchar(max)
declare @myTable varchar(max)
declare @totalValue int

set @myTable = ‘tableName’
set @myVar = ‘columnName’

set @sqlStr = ’select fooBarBaz=sum(‘ + @myVar + ‘) from ‘ + @myTable
print @sqlStr
declare @tempTable table (fooBarBaz int)
insert @tempTable exec(@sqlStr)
select @totalValue = fooBarBaz from @tempTable
print @totalValue

As you can see, though, it’s very messy having to go through a temporary table to hold the result set.

Thanks in advance….

SET @SQL=’DELETE ‘+@TABLENAME+’ WHERE profile_id=’+@EMPID+’ AND assignment_id= ‘+@ID
EXEC(@SQL)
END

whem i am trying to execute it it is giving error
i tried like this
exec SP_TEMANAGMENT_DELETEDOCUMENT_FROM_REPORTS 400,36,’emp_assignment’

Basic flow is to pull a set of connection information about various servers, then work through each set making a call to a standard stored procedure which moves and transforms the data to its final resting spot in the reporting database.

I need to keep security in mind and manual configuration, hence the choice to pull connection information for data sets that are maintained and create a connection to each server. Each server is configured and setup the same and contains the same database and fields.

Is there a way to send dynamic connection information into a stored procedure or other object to move the data or am I limited to using a coded (perl, .net, php) script to make the connections and execute the same set of code?

I posted simple query so that anybody can understand. My original query is

SELECT ISNULL(NULL, EXEC (‘BEGIN
EXEC Inferred_CreateDimPatientMember 1
SELECT PatientKey FROM KeyMapPatientView WHERE CphPatientID = 1 END’))

I know your Tip1 and Tip2 can work but those are not helpful in my case because I want to get an output in single sql statement.

So In my above query I am expecting to have output as PatientKey.

Thanks
Hitesh Savalia.

how about this ?
SELECT ISNULL(NULL, 1)

Output : 1

– Why dont you try any one of this,

Tip 1:

if exists ( select cola from table1 where cola is null)
begin
set @sql = execute dynamic sql parameter, with output parameter

set cola = output value from above dynamic sql
end

Tip 2 :
select
case when cola is null then another_value
from table1

Please post complete question, what is your requirement, what is that you are trying to execute ?

~IM

SELECT ISNULL(NULL, EXEC(‘SELECT 1′))

Expected output is 1

If we run only EXEC(‘SELECT 1′) then it works.

Please let me know what should I use?

Thanks,

To assign values dynamically we need to use sp_executesql procedure. The N’ is mandatory as the parameter should be converted to NText.

USE [MyDB]
GO
/****** Object: StoredProcedure [dbo].[selectedSortedOutput] Script Date: 01/27/2009 11:02:27 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[selectedSortedOutput](@sortColname nvarchar(50))
As
declare
@FName nvarchar(50),
@Sql nvarchar(1500);
begin
set @Sql = ’select @FName=FirstName from Customer order by ‘ + @sortColname;
exec sp_executesql @Sql,N’@FName nvarchar(50) OUTPUT’, @FName OUTPUT;
Print @FName;
end;

@whereclause =’ And username=”admin”’

In above statement, multiple single quotes are used.

@tablename varchar(50),
@whereclause varchar(max)
AS
BEGIN

DECLARE @sqlquery varchar(5000)

SET @sqlquery = ‘SELECT * FROM ‘+@tablename+’ WHERE 1=1 ‘+@whereclause

EXEC(@sqlquery)

END

Suppose,
@tablename = BuyerMaster
@whereclause = And username=admin

It give an Error “Invalid column name admin”

How can I put admin in single quotes as I am getting the values from ASP.NET page.

Please Help Me,
Please.

Thanking You,
Rahul

how to fill SQL varaible if using a statement inside in EXEC command line eg.

DECALRE @Value bigint
SET @Value = EXEC (‘SELECT COUNT(ID) FROM Table’)
SELECT @Value

Is this is possible in this way to capture return value from concatenated statement…or there is other way to do it.

in short what i want is to fill up a variable by return value from exec statement and not from simple select query statement.

thanks if u help me…

How can I execute a stored procedure stored on instance A on instance B? The Variable is a database name of instance B.

Can somebody help me?

Thx

Thanx in advance.

You should not need GO Statement in EXECUTE.

If you need something like that use semi-comma.

How to use a GO Statement in a dynamic SQL Query.

declare @strsql varchar(max)

SELECT @strsql = ‘ Stmt1
GO
Stmt2
GO’

EXECUTE (@strsql)

This gives an error : Incorrect syntax near GO.

>EXEC (’Use pubs’)
That command would change the database within the EXEC() command. Any additional commands would use the pubs database.

Basically the command executed within EXEC() has its own context.

EXEC (‘Use pubs’)

The command is successfull but the database setting didnot change when I execute in Query Analyzer?
