Can I Have Exec(...) Statements Within A Transcation ?
Sep 17, 2004
Is the following T-SQL correct, in which I am trying to make sure that th effect of 3 stored procedures gets reversed in case of an error ? I know if in place of stored procedures I had action queries like 'ActionQry1', 'ActionQry2' and 'ActionQry3' then the transaction logic would work. But will it work even if exec(....) statements are there in the transaction ? Each stored procedure is made up of an action query.
I am writing a stored procedure to select some information from two tables and I would also like to Execute a function using the userid information from the processing in the where clause of the Select statement. Is the syntax below possible?? If yes, could you please help me understand exactly what I may be doing wrong here.. If no, can you please help with better syntax. Thanks in advance
SELECT M.UserID, M.FullName, (EXEC calcPoints M.UserID) as 'UserPoints' FROM MissionUsers M LEFT OUTER JOIN MissionUserInfo MU ON M.UserID = MU.UserID WHERE M.EMAIL = @UserEmail
I have two databases lets call them A & B, they reside in two PCs, each pC has its own C/C++ program working with A or B, Two PCs are linked by PPP (for example), but the link is not permonent available, the link is only available at certain time period, for example, at midnight.and the link is only last certain period, during this period, A & B will do the transcation replica( just heard about that!) to make them identical, A=B.
Now are my questions.
(1) Can database use dial up modem itself ? For PC program it is not the problem, but I am not sure whether MS SQL server database can be configured to do such job automatically ?
(2) Can database have awareness of whether the link is available or not ? For example A is dialing modem, and B realize that there is a incoming call.
(3) Once link is established, how two databases start to do the transcation replica ? Does SQL server has such ability to do this automatically ?
(4) Can database notice PC program that changes has occured ? so PC program can process it, see display new data.
I have to post this problem again because I didn't get the correct way.
I have SQL Server 2000 on client (Windows XP) and server (Windows 2003). DTC is running on both side. There is a transcation like,
BEGIN TRAN INSERT MyTable SELECT * FROM MyView COMMIT
MyView get data by:
SELECT * FROM OPENDATASOURCE ('SQLOLEDB', 'Data Source=PROD;UserID=DBDev;Password=WORLDWID').PRODD ata.dbo.CService
PROD is the production server.
When I run this query, there is the error message,
Server: Msg 8501, Level 16, State 1, Line 2 MSDTC on server 'PROD' is unavailable. Server: Msg 7391, Level 16, State 1, Line 2 The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction. OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d01c].
I am talking to SQL Server CE through LINQ to SQL in Visual Studio 2008. I have a table that uses location information as the primary key. The state associated with the location may change so sometimes I add new records and sometimes I update existing records. Before adding records to the table I verify that no existing record exists with the same primary key.
When I query against SQL Server Compact 3.5, I don't pick up records in the active transaction. I thought that the previous version of SQL Server CE did pick up records in the active transaction.
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?
declare @TableName Varchar(255);--Just For Testing---DELETE!! declare @Filename varchar(255); --Store Distinct filename declare @DSNo Varchar(255);-- Use 'set' to execute Var TableName declare @SumUnits Varchar(255); --Use 'set' to calculate sum of units declare @SumValue Varchar(255); Set @TableName = 'TrDs01' -- Testing Only--DELETE!!

Just the Bold and underlined bit "exec(DSNo)"..... is this doable in some way? can i use exec to retrieve the value to insert to data supplier. As far as i know i have to do it like this because im using a variable as the table name...
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.
I found this statement in BOL and it didn't make it to work.Is anybody out there who ha the same problem? Database is MASTER. USE master EXEC ("USE pubs") SELECT * FROM authors
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 am seeking an expert help for the following issue, please find the code am using first ...the problem mentioned below that... ---------------------------------------------- DECLARE ,@DBName VARCHAR(128) ,@LoginName VARCHAR(128) ,@SQL VARCHAR(2000)
EXEC(@SQL) IF @@ERROR <> 0 PRINT @@ERROR ELSE BEGIN PRINT 'Revoked database access of [' + @LoginName + '] from the database ['+ @DBName +'] PRINT @@ERROR END --------------------------------------------------------------
Suppose I am trying to REVOKE a database access which not exist iw will give me a mesage like , Server: Msg 15008, Level 16, State 1, Procedure sp_revokedbaccess, Line 36 User 'Loginname' does not exist in the current database.
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'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?
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:
Code is really not important. Any sys SP can replace the above code.
I am getting the following error Msg 8164, Level 16, State 1, Procedure sp_MSload_tmp_replication_status, Line 80 An INSERT EXEC statement cannot be nested.
I have seen the following link which discuss this issue, http://www.sommarskog.se/share_data.html But there is no solution there.
I tried with sp_executesql and EXEC(), but unable to get the result. Can anyone put some light?

How to exec the following function from my select statement and get my return value:-
ALTER FUNCTION [dbo].[fn_qty] (@qty decimal (10,4), @price decimal (10,4), @pieces int, @mpt int=0)
returns decimal (10,4)
AS begin declare @totamt decimal (10,4) if @pieces = 0 begin SET @totamt = (@QTY * @price) end else begin SELECT @mpt = (SELECT case mpq when 1 then 10 when 2 then 100 else 100 end FROM ims.parm) SET @totamt=(((FLOOR(@QTY)*@PRICE))+(((@qty-FLOOR(@QTY))* @mpt)/@pieces)*@price) end return @totamt end
I can exec the function as exec command as follows:- exec @totamt( erpinv.dbo.fn_qty 3.5,6,24 )
Hello, I am very, very new to the world of SSIS and from a totally different platform (iSeries), learning, digging and finding golden nuggets as I go.
Two questions please.
Question One:
I am presently encountering the following exception.
SSIS package "DW.CUST_CNCL_ORD.dtsx" starting. Error: 0xC00291E2 at BP Parter Exec SQL, Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_Rowset". Task failed: BP Parter Exec SQL Warning: 0x80019002 at DW CUST_CNCL_ORD: The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. SSIS package "DW.CUST_CNCL_ORD.dtsx" finished: Failure.
Try as I do to find information regarding this exception, I am not able to. Can anyone share their wisdom on this topic?
Question two:
Is there a book that you may recommend that will contribute to my learning this new platform and evironment? I presently have the SQL Server 2005 integration services book.
Thank you in advance for any information you may provide.
