Transact SQL :: Using EXEC To Execute A Formula Stored In A String
May 31, 2005
Basically, I have a table with a column that stores mathematical formulas in string format. When my UDF is executed, it needs to select an appropriate formula from this table and evaluate it using values that are stored in local variables.
Look at the example below:
Suppose I have a string named @vcFormula that contains the following:"@dVar1 + @dVar2 / @dVar2"Now suppose I have a variable named @dVar1 that contains a value of 1.0, and variable @dVar2 contains a value of 2.5. I can use the REPLACE function to change my original string to look like this:"1.0 + 2.5 / 2.5"
Now I want to execute this string and find the numeric result, placing it in a variable named @dResult. The following works, but presents a problem:CREATE TABLE #Result (dResult decimal(20, 10))INSERT #Result EXEC('SELECT ' + @vcFormula)SELECT @dResult = dResult FROM #ResultThe problem with using this method comes from the fact that I need to be able to evaluate @vcFormula from within a user-defined function, but temporary tables are not allowed inside UDF's.
So I attempted to change the temporary table above into an instance of the TABLE data type. This didn't work either because EXEC cannot be used to populate instances of the TABLE data type. Then I came up with the bright idea to put the code above in a SP and call the SP from the UDF, but of course UDF's are not allowed to call SP's. Specifically, is there any way to execute a command/formula that is contained within a string other than by using EXEC?

In 'MyTable' I have the following columns...
TotalNumber (numeric)
Weighting (numreric)
Hours (numeric)
Minutes (numeric)
Formula (nvarchar)
'Formula' column stores a literal string of the formula that may include some, none or all of the previous columns or be NULL.
Here are some examples of the actual strings it stores...
Weighting*Hours
Weighting+(TotalNumber*Hours)
Weighting*Hours)+(TotalNumber*2)
etc etc
All I want to do is create a UDF that will evaluate these strings as math formula and return the value depending on the values of the other columns in the row.
Bear in mind that there may not be a string formula at all for some rows, in which case the value of teh Hours column alone should be the result.
I can do this in vb using the 'Replace' function but am having difficulty in translating it over to T-SQL.
Here is the vb version i use in Ms Access...
getFormula(strDutyType As String, dblTotalNumber As Double, dblWeightingAs Double, dblHours As Double, dblMinutes As String, strFormula As Variant)
If IsNull(strFormula) Or strFormula = "" Then
getFormula = dblHours
Exit Function
End If
'Create the expression string with literal values
strExpression = Replace(strFormula, "TotalNumber", _
CStr(dblTotalNumber), , , vbTextCompare) _
strExpression = Replace(strExpression, "Weighting", _
CStr(dblPF), , ,vbTextCompare)
strExpression = Replace(strExpression, "Hours", _
CStr(dblHours), , , vbTextCompare)
strExpression = Replace(strExpression, "Minutes", _
CStr(dblMinutes), , , vbTextCompare)
'Evaluate the math of the literal expression
getFormula = Eval(strExpression)
-----------
Many Thanks

Hi everybody, I would like to know if it's possible to execute a stored procedure, passing it parameters, using not CommandType.StoredProcedure value of sqlcommand, but CommandType.Text.
I tried to use this:
sqlCmd.CommandType = CommandType.Text
sqlCmd.Parameters.Add(sqlPar)
sqlCmd.ExecuteNonQuery()
With this sql command:
"exec sp ..."
I wasn't able to make it to work, and I don't know if it's possible.
Another question:
if it's not possible, how can I pass a Null value to stored procedure?
This code:
sqlPar = new SqlParameter("@id", SqlDbType.Int)
sqlPar.Direction = ParameterDirection.Output
cmd.Parameters.Add(sqlPar)
sqlPar = new SqlParameter("@parent_id", DBNull)
cmd.Parameters.Add(sqlPar)
doesn't work, 'cause I get this error:
BC30684: 'DBNull' is a type and cannot be used as an expression.
How can I solve this?
Bye and thanks in advance.
P.S. I would prefer first method to call a stored procedure ('cause I could call it with 'exec sp null' sql command, solving the other problem), but obviusly if it's possible...=)
Sorry for grammatical mistakes.

Hi all,
In my SQL Server Management Studio Express (SSMSE), I executed the following sql code suuccessfully:
--insertNewRocord.sql--
USE shcDB
GO
CREATE PROC sp_insertNewRecord @procPersonID int,
@procFirstName nvarchar(20),
@procLastName nvarchar(20),
@procAddress nvarchar(50),
@procCity nvarchar(20),
@procState nvarchar(20),
@procZipCode nvarchar(20),
@procEmail nvarchar(50)
AS INSERT INTO MyFriends
VALUES (@procPersonID, @procFirstName, @procLastName, @procAddress,
@procCity, @procState, @procZipCode, @procEmail)
GO
EXEC sp_insertNewRecord 7, 'Peter', 'Wang', '678 Old St', 'Detroit',
'Michigon', '67899', 'PeterWang@yahoo.com'
GO
=======================================================================
Now, I want to insert a new record into the dbo.Friends table of my shcDB by executing the following T-SQL and Visual Basic 2005 codes that are programmed in a VB2005 Express project "CallshcDBspWithAdoNet":
--Form1.vb--
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Public Class Form1
Public Sub InsertNewFriend()
Dim connectionString As String = "Integrated Security-SSPI;Persist Security Info=False;" + _
"Initial Catalog=shcDB;Data Source=.SQLEXPRESS"
Dim connection As SqlConnection = New SqlConnection(connectionString)
connection.Open()
Try
Dim command As SqlCommand = New SqlCommand("sp_InsertNewRecord", connection)
command.CommandType = CommandType.StoredProcedure
EXEC sp_insertNewRecord 6, 'Craig', 'Utley', '5577 Baltimore Ave',
'Ellicott City', 'MD', '21045', 'CraigUtley@yahoo.com'
Console.WriteLine("Row inserted: " + _
command.ExecuteNonQuery().ToString)
Catch ex As Exception
Console.WriteLine(ex.Message)
Throw
Finally
connection.Close()
End Try
End Sub
End Class
===========================================================
I ran the above project in VB 2005 Express and I got the following 5 errors:
1. Name 'EXEC' is not declared (in Line 16 of Form1.vb)
2. Method arguments must be enclosed in parentheses (in Line 16 of Form1.vb)
3. Name 'sd-insertNewRecord' is not declared. (in Line 16 of Form1.vb)
4.Comma, ')', or a valid expression continuation expected (in Line 16 of Form1.vb)
5. Expression expected (in Line 16 of Form1.vb)
============================================================
I know that "EXEC sp_insertNewRecord 6, 'Craig', 'Utley', '5577 Baltimore Ave',
'Ellicott City', 'MD', '21045', 'CraigUtley@yahoo.com' "in Line 16 of Form1.vb is grossly in error.
But I am new in doing the programming of T-SQL in VB 2005 Express and I am not able to change it.
Please help and advise me how to correct these problems.
Thanks in advance,
Scott Chang

There is a column in a table that has values like '23 + 45 + 63', '2 + 54 - 22'... and so on. I want to get the result of this formula as float like 131, 34... and so on. Is that possible with a SELECT statement. I tried:
SELECT CAST('23 + 45 + 63' AS FLOAT)
Didn't work.

Hi guys,
I have a large text that can have some ENTER character inside of it. The problem is that the text must be inserted into a txt file in a single row. So what I need is to find those ENTER character and replace them with a space so as to have the whole string in one row.
How can I build that formula in derivide column?
Thanks for your help

Hi There
Ok i have a piece of test ddl sql that is written to a varchar(max) column. Entered by a user.
GO's and missing semi colons seem to break it, if you try to execute it with EXEC or sp_executesql, however the sql can be executed on Management Studio as is, so how can i execute it as is successfully?
In a nutshell i retreive the DDL sql from the column into a nvarchar(max) variable called @SQL , and i need to execute it.
I have tried:
EXEC(@SQL) and sp_executesql @SQL, both return the error , incorrect syntax near 'GO'.
The problem is obviously i have to have the go statements, in order to create some fo the ddl objects correctly. But EXEC and sp_executesql do not like that. I also found that semi colons are required after every statement.
The sql is as follows:
--===============================================================================
--DDL script
CREATE LOGIN TEST_LOGIN WITH PASSWORD = 'Whatever!@(!';
CREATE USER TEST_USER FROM LOGIN TEST_LOGIN;
CREATE TABLE TEST_TABLE (Column1 int NULL);
GRANT INSERT ON TEST_TABLE TO TEST_USER;
CREATE CLUSTERED INDEX TEST_INDEX ON TEST_TABLE (Column1);
GO
CREATE PROCEDURE TEST_PROCEDURES
AS
SELECT GETDATE();
GO
CREATE VIEW TEST_VIEW
AS
SELECT * FROM TEST_TABLE;
GO
--ALTER DDL
ALTER VIEW TEST_VIEW
AS
SELECT GETDATE() AS 'DATE';
GO
ALTER PROCEDURE TEST_PROCEDURES
AS
SELECT * FROM TEST_TABLE;
GO
--DROP DDL
DROP INDEX TEST_TABLE.TEST_INDEX;
DROP TABLE TEST_TABLE;
DROP VIEW TEST_VIEW;
DROP USER TEST_USER;
DROP LOGIN TEST_LOGIN;
DROP PROCEDURE TEST_PROCEDURES;

I'm looking for a way to refer to a package variable within any
Transact-SQL code included in either an Execute SQL or Execute T-SQL
task. If this can be done, I need to know the technique to use -
whether it's something similar to a parameter placeholder question
mark or something else.
FYI - I've been able to successfully execute Transact-SQL statements
within the Execute SQL task, so I don't think the Execute T-SQL task
is even necessary for this purpose.

Hello all,
I am running a package on a 64-bit server using the 32-bit dtexec. It contains an embedded Execute DTS 2000 package. I deployed the package to the server using the sa account. I set up a SQL Agent job that runs under an account that should have complete admin privileges. The network guys tell me that Legacy components have been installed (although I believe that shouldn't be necessary because SSIS is installed). This is SQL Server 2005, SP2.
When I execute this job, I receive this error message:
Executed as user: Domainuser. ...age Utility Version 9.00.3042.00 for 32-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved.

Hi All,
I am using SQL Server 7 Beta 3 and I am having trouble with using a variable
in an EXEC statement.
I have a stored procedure that is designed to retrieve a serial
number from a table and then increment it by one(1) and return the
original serial number to the calling function.
As long as the table name is hardcoded the following code works fine:
CREATE PROCEDURE IncrementSerialIDNo
(@serial_num_temp varchar(15), @serial_num_output varchar(15) output)
AS
BEGIN TRANSACTION
BEGIN
SELECT @serial_num_temp = tblSerialNo.SerialNo
FROM tblSerialNo
SELECT @serial_num_output = @serial_num_temp
UPDATE tblSerialNo
SET tblSerialNo.SerialNo =
CONVERT(varchar(15),(CONVERT(integer,@serial_num_t emp ) + 1))
IF (@@error = 0)
COMMIT TRANSACTION
ELSE
ROLLBACK TRANSACTION
END
RETURN
However, if I change the table name to a variable that is passed to the
stored procedure as a argument, I need to use the EXEC statement.
My problem is that for the EXEC statement to work I need to escape the
variables and I run into a problem with the " = " ( equal sign ).
Example:
DECLARE @SerialTable as varchar(30), @CompanyNo as varchar (3)
SELECT @CompanyNo = `001`
SELECT @SerialTable = `tblSerialNo` + @CompanyNo
EXEC ( `SELECT ` +@serial_num_temp + `= SerialNo FROM ` +
@SerialTable )
Following is the error message that I keep getting:
Server: Msg 170, Level 15, State 1
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax
near `=`.
No amount of testing with different qoutes or doublequotes and such,
have made any difference.
I have tried numerous variations on the above SELECT statement with the
same end result of the error on the "=" sign.
I cannot seem to assign one variable to another using the "=" (equal sign)
in an EXEC statement.
Does anyone have example code of using the equal sign to assign one variable
to another in an EXEC statement or can someone point me in the right direction?
Thanks in advance for any and all help.

Hi.
I have been trying to find a solution to this for some time now. Was wondering if some1 had done is earlier and has a solution.
I have a 2 server machines.
Namely: ServerOne and ServerTwo
ServerOne (main server, On 1 machine.)
Table - Foofoo
ServerTwo (secondary server, on another machine)
Table - Booboo
I want to be able to link these two servers and work with them.
At the moment I do something like this.
NB. My Stored Procedure is on ServerOne
declare @server varchar(100)
Select @server=Servername from ServerOne.systemsettings where name='secondary'
-- @server is not equal to 'ServerTwo'
declare @str varchar(8000)
set @str = '
select *
from Foofoo f
join ' + @server + '.myDB.dbo.Booboo b on b.id = f.id '
exec(@str)
My problem is that this works fine but I do not like working with long strings and then executing them at the end.
I have also been told that SQL's performance on this is not entirely that well as normal select's would be.'
Another thing that could be used is SQl's own linked servers method but apparently out system was designed some time ago and a lot of things have been developed around the current technic.
Our server names also change quite frequently making hadcoding server names difficult.
Using the string exec convention also hides from sql when you do a dependency search of a particular table.
Is there a way I can save the server name on @server and then just add it to the select stmt without using the long stringing idea.
Any feedback with ideas and solutions will be greatly appreciated.
Bhit.

I am trying to make up a SQL string which will be executed with the Exec command
I want to add a return column that is not in the table, and the table columns:
something like
Select @Ten As Ten, @Tablename.* From @Tablename (
where @Ten has an integer value. )
The statement was originally:
select @SQL = 'select * from ' + @TempName
exec (@SQL)
which had no problem. Then I needed to add an extra column of static data to all the returned rows, and confusion !!!!!

<<Select Replace(Keyword,',',' ') AS Keyword, SICCode From zlk_SICCodeKeyword Where Keyword like 'real%' order by Keyword >>

Hey guys, needless to say I'm new at this.
What I'm trying to accomplish is to execute a SQL string via exec and inside it set the value of a local variable. I understand that I cannot do this the way I'm currently doing it because an Executed string runs in a scope of its own so local variables are invisible. And sure enough this is the error I get. So how do I make this work?
Code snip:
declare @ErrMessage as varchar(1000)
set @Sql = 'if exists ( select * from ' + @TargetTable + ' where (' + @ValueField + '=' + '''' + @NewValue + ''''
set @Sql = @Sql + ' and ' + @TagField + '= ' + '''' + @Tag + '''' + '))' + @CRLF
set @Sql = @Sql + 'set @ErrMessage = ''Insertion could not be performed. ' + @NewValue + ' is already an entry in the table. '''
So what I want is check if a certain table has entries...what table? I don't know, there are tens that this check will apply to. And if that tavle has an entry that satisfies the where clause then assign the appropriate error message to @ErrMessage.
I understand sp_executesql might do the trick because it allows passing local params back and forth.
Any ideas on how to make this work? I appreciate the effort.

Newbie problem: Working with SQL Server 2000 (web admin), I have a table named OrderItems created with this query:
CREATE TABLE dbo.OrderItem
(fkOrderID int NOT NULL,
fkMenuItemID int NOT NULL,
ItemSize nvarchar(50) NOT NULL,
ItemName nvarchar(50) NOT NULL,
Quantity int NOT NULL,
LineValue money NOT NULL)
I have created a second table that will contain summary data (total quantity for each item):
CREATE TABLE dbo.OrderItemTotal
(fkMenuItemID int NOT NULL,
ItemName nvarchar(50) NOT NULL,
TotalQuantity int NOT NULL)
I want to draw the fkMenuItemID and ItemName directly from the OrderItem table and have the TotalQuantity column dynamically sum the total number of items for each fkMenuItemID so that as orders are added, the OrderItemTotal table is automatically updated.
This sort of thing is easy in a spreadsheet using formulas, so I assume that there must be comparable methods in T-SQL. From browsing the archives I get the sense that I may need a calculated formula within a stored procedure. This is what I have so far, which does not contain a calculated formula for the TotalQuantity column.
CREATE PROCEDURE dbo.usp_InsertOrderItemTotal
@MenuItemID int,
@ItemName varchar(50),
AS
INSERT INTO OrderItemTotal
VALUES(@MenuItemID, @ItemName)
Am I on the right track with my thinking? Where do I go from here? Any help with this would be greatly appreciated.

Hi,
I have written a stored proc to bulk insert the data from a data file.
I have a requirement that i need to insert the data into a table of which the name is not known. I mean to say that the table name will be passed as a parameter to the stored proc. And also i need to insert the date that will also be passed as the parameter to the stored proc
The follwing statement works fine if i give the table name directly in the query
Code Snippet
DECLARE @LastUpdate varchar(20)
SET @LastUpdate = 'Dec 11 2007 1:20AM'
INSERT INTO Category
SELECT MSISDN, @LastUpdate FROM OPENROWSET( BULK '\remotemachinedatafile.txt',
FORMATFILE = '\remotemachineFormatFile.fmt',
FIRSTROW = 2) AS a
To satisfy my requirement ( i.e passing the table name dynamically , and the date) , i have formed the query string ( exact one as above ) and passing it to EXEC statement. But its failing as explained below
Code Snippet
@Category - Will be passed as a parameter to the stored proc
DECLARE @vsBulkSQL VARCHAR(MAX)
DECLARE @LastUpdate varchar(20)
SET @LastUpdate = 'Dec 11 2007 1:20AM'
SELECT @vsBulkSQL ='INSERT INTO '+ @Category + ' SELECT MSISDN, ''' + @LastUpdate +''' FROM OPENROWSET ' + '( BULK ' + '''' + '\remotemachinedatafile.txt'+ ''''+ ' ,' +
+ ' FORMATFILE ' + '=' + ''''+ '\remotemachineFormatFile.fmt'+ ''''+ ',' +
' FIRSTROW ' + '=' + '2' + ')' + ' AS a'
Print @vsBulkSQL - This prints the folliwing statement
INSERT INTO Category SELECT MSISDN, 'Dec 11 2007 1:20AM' FROM OPENROWSET ( BULK '\remotemachineDataFile.txt' , FORMATFILE ='\remotemachineFormatFile.fmt', FIRSTROW =2) AS a
Exec @vsBulkSQL - This statement gives the following error
The name 'INSERT INTO Sports SELECT MSISDN, 'Dec 11 2007 1:20AM' FROM OPENROWSET ( BULK '\remotemachineSecond.txt' , FORMATFILE ='\remotemachineFormatFile.fmt', FIRSTROW =2) AS a' is not a valid identifier.
Can any one please point out where am i doing wrong? Or do i need to do anything else to achive the same

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.

How do I use a @variable to hold on value return from an exec ('string command') statement.
Example for:
declare @OldID int

set @db = 'DBNAME'
set @OldOwner = 'USERNAME'
select @cmd = 'select uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
exec (@cmd)
How can I use @OldID to hold on UID return from this statement.
When I try use:
select @cmd = 'select @OldID = uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
then I'm getting a error message: @OldID not declare.
