EXEC Dynamic Sql
May 13, 2003Running this dynamic sql construct gives me an error because somehow it does not accept my variable @table or it is recognised differently. If run directly no problem but apparently the single quotes are a problem.
Print @Table (db and table name: opms..transactions)
Select @sql = 'Select * From Payments where not exists (Select * from Hist Where TableName = ' + @Table + ' and sYear = '+ @Year + ' and sMonth = ' + @Month + ')'
Print @sql
EXEC (@sql)
opms..Transactions
Select * From Payments where not exists (Select * from Hist Where TableName = opms..Transactions and sYear = 2003 and sMonth = 12)
Server: Msg 1004, Level 15, State 1, Line 1
Invalid column prefix 'opms.': No table name specified
Any idea?

Dynamic SQL And EXEC
Aug 11, 2005Hello,
I'm trying to do something like the following, but it keeps complaining that I need to declare @max, even though I have (and it is of the same type as link_id).
EXEC('SELECT @max=MAX(link_id) FROM '+ @str1)
I've looked into sp_executesql but I'm not entirely sure how that functions. Any suggestions?
Exec Multiple Batches (GO) With Dynamic Sql
Jun 10, 2008Hello SQL Team!
I'm stuck at this problem for days and need help.
The problem is with the GO keyword. I know the GO causes the batch to get executed and all local variables are lost. But I can't seem to find a work around. I would like each stored procedure to get executed in different batches.
create table sql_cmd(cmd nvarchar(255))
insert into sql_cmd(cmd) values('exec user_sp param1,''param2'')
insert into sql_cmd(cmd) values('exec user_sp2 param1,''param2'')
declare @sql nvarchar(255)
declare c_sql cursor --small table peformance not a problem. Also open to other suggestions
for select cmd from sqlcmd
open c_sql
fetch next from c_sql
into @sql
while @@fetch_status = 0
begin
print @sql
exec sp_executesql @sql
GO
fetch next from c_sql
into @sql
end
Incorrect Syntax Near The Keyword 'EXEC' (Dynamic Sql Statement Error)
Nov 1, 2007Following is the stored procedure iam trying to create.Here i am trying to
First create a table with the table name passed as parameter
Second I am executing a dynamic sql statement ("SELECT @sql= 'Select * from table") that returns some rows.
Third I want to save the rows returned by the dynamic sql statement ("SELECT @sql= 'Select * from table") in the tablei created above.All the columns and datatypes are matching.
This table would be further used with cursor.
Now i am getting a syntax error on the last line.Though i doubt whether the last 3 lines will execute properly.Infact how to execute a sp_executesql procedure in another dynamic sql statement.ANy suggestions will be appreciated.
CREATE PROCEDURE [dbo].[sp_try]
@TempTable varchar(25)
AS
DECLARE @SQL nvarchar(MAX)
DECLARE @SQLINSERT nvarchar(MAX)

Can Exec Select But Can't Exec Sp
Oct 31, 2007I have two SQL Server 2000 (one is localhost, one is remote with VPN IP 192.168.5.4).
I can select * from [192.168.5.4].db.dbo.test but I can't exec [192.168.5.4].db..spAdd in localhost.
These select and sp is OK for 1 or 2 week without any problem,but it didn't work one day.
Can some one explain why?
Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns
Aug 25, 2007Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

SSRS 2005 - Email Report On Execution To Dynamic List With Dynamic Parameters = No Schedule
Nov 23, 2007Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.
So, is this possible using data driven subscriptions? Scenario is:
1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.
Any tips on how to get this working?
Thanks

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?
May 2, 2007If anyone could confirm...
SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?
T-SQL (SS2K8) :: How To Add Inline TVF With Dynamic Columns From CRL Dynamic Pivot
Mar 9, 2015I have tried building an Inline TVF, as I assume this is how it would be used on the DB; however, I am receiving the following error on my code, I must be missing a step somewhere, as I've never done this before. I'm lost on how to implement this clr function on my db?

Mixing Dynamic SQL With Non-Dynamic In Stored Proc
Mar 24, 2007I have a Stored Procedure for processing a Bill of Material.
One column on the Assembly Table is a Function Name that contains some busniess rules.
OK, now I'm doing a Proof of Concept and I'm stumped.
Huuuuh!
I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.
Note: The function just returns a bit.
So; here's what I had in mind ...
if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output
CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS
declare @SQL varchar(8000)
set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'
exec (@SQL)
GO
Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.
So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?
My many thanks to anyone who can solve this riddle for me.
Thank You!
Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.
------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
.

etc.

Dynamic Source And Dynamic Destination
Apr 15, 2008I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have

Exec Sql
Apr 28, 2006I need help understanding the syntax of the "exec sql" statement.
i am looking at code that build an sql string such as
sql="exec SOMETHING Session("id")"
or something like that.
then, there is
conn.execute(sql)
My question is the "SOMETHING" in the sql statement...is what? I know it is user defined (object or variable or such), but what exactly is it? i look through the rest of the code and don;'t see SOMETHING defined elsewhere.
i am not sure if i am asking the question right. i don't understand what the SOMETHING is doing, or why it is there.
in particular, the code i am examining is
sql="exec SurveyDelete "&"'" & Session("StudentID") & " ' "
conn.execute(sql)
i understand the this statement will delete a record, but how does it handle "SurveyDelete", how does it know what the is when it is not defined anywhere else in the code?

Mar 28, 2006Hi,
I have a written a SP to do indexdefrag to all user table indexes in a databases...I had to use dynamic sql so I can reuse this code for any DB...
declare @strsql varchar(500)
set @strsql = ' dbcc indexdefrag('+'''DBName'''+',554556545,3)'
exec (@strsql)
When I execute the above script, I immeaditely see the results in the query analyser like below:
Pages Scanned Pages Moved Pages Removed
------------- ----------- -------------
3 0 0
Looks like the indexdefrag did not happen since the logical fragmentation is still a high number like 30%.....
Just wondering whats goin on..
Thanks.

It appears that users do not have permission to execute xp_sendmail. I guess this is because it is executed on the master database. Is there a way I can give them permission to this stored proc?

Return A Value Using EXEC
Jan 12, 2004OK, I'm fairly new to SQL Server, but I know SQL and databases pretty well. I'm just starting to use the dynamic SQL feature of SQL Server (with EXEC), and am wondering how to return a scalar value from a dynamic SQL expression. I realize I can't use EXEC in a user-defined function, but I want to create a stored procedure with one OUTPUT variable so I can simulate a function. The following code does not work, because EXEC does not return a value:
CREATE PROCEDURE dbo.ExecFunction ( @ScalarSELECTString varchar(250), @@ReturnVal sql_variant )
set @@ReturnVal = ( exec @ScalarSELECTString )
go
So, I was wondering if someone might be able to suggest a way to re-write the above code to achieve the same effect. Thanks in advance.
