Running 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
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?
Hello 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
Following 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.
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. http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1
Hi, 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.
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?
I 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?
Error: Msg 156, Level 15, State 1, Procedure clrDynamicPivot, Line 18 Incorrect syntax near the keyword 'external'. CREATE FUNCTION clrDynamicPivot ( -- Add the parameters for the function here @query nvarchar(4000), @pivotColumn nvarchar(4000),
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

I've looked up Books Online on Dynamic Cursor/ Dynamic SQL Statement.
Using the examples given in Books Online returns compilation errors. See below.
Does anyone know how to use Dynamic Cursor/ Dynamic SQL Statement?

I 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
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.
When I use EXEC in a stored procedure ( after building complex option logic) it produces an returns an error of 'Access denied' on the underlying tables. All objects are dbo owned and execute permission has been given to all users. Can ant one help? Rob
When using a SP for getting a recordset is there any issues with using exec like in: rs.open "exec spWhatever"... Should I use rs.open "spWhatever" or does it really matter performance wise on the SQL server?

I 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.
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?
Hi, I have an sql query like this :DECLARE @TableName varchar(200), @ColumnName varchar(200), @EmployeeID varchar(200), @Result varchar(200);SET @TableName = 'Customer';SET @ColumnName = 'First_Name';SET @CustomerID = 28;-- This line return ErrorSET @Result = EXEC ('select' + @ColumnName + ' from ' + @TableName + ' where Recid = ' + @CustomerID + '');Print @Result; I am pretty sure the SELECT statement in EXEC will only return 0 or 1 record. But how to capture result from EXEC? Thanks
is it possible to have a sproc with a input parm of a column name and have this column name be inserted into an exec statement that runs and provides the output as a OUTPUT parm instead of a result set?
i can get the sproc to take the column name as a parm, run the exec, but cannot figure out how to assign the "dynamic sql" output to a OUTPUT variable instead of returning the result set.

But the @@ERROR will return 0 as it was a successfull execution of EXEC(@SQL) .
So How can I retrieve the error value 15008 in a variable ..?
I have a stored proc that assigns a value to a field based on user input from an Access front end.
The last part of the stored proc sends an email if certain conditions are met.
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?
The users are getting this message:
EXECUTE permission denied on bject 'xp_sendmail', 'database master', owner 'dbo'.(#229)
I am creating a dynamic query and using exec to execute it inside of a function. This query will return only one value. How can I get the value the query returns into a variable?
Functions can not call stored procedures, and they can not use temporary tables.
OK, 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:
