Exec In A Function

Oct 15, 2004

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.

Thanks much

Exec Sproc In A Update Function

Feb 5, 2004

Folks

Here is a query which updates certain values. GetAddress is another
sproc which returns addrId. I have to pass certain values ie
strAddress1 strCity .....intZip4 values in the sproc GetAddress and execute the update query. In doing so it says GetAddress in
not a recognized function name. Is the syntax correct to exec sproc
GetAddress.


update Persons
set
Persons.strLastName=H.strLastName,
Persons.strNameSuffix=H.strNameSuffix,
Persons.lngHomeID= GetAddress (H.strAddress1,strAddress2,H.strCity,H.strState,H. strZip,H.intZip4),
Persons.lngMailID= GetAddress(H.strAddress1,strAddress2,H.strCity,H.s trState,H.strZip,H.intZip4)
from ALSHeadr H
where Persons.lngSSN=H.lngFedTaxID



FYI I can post GetAddress sproc but it is working properl.
I just want to know how to pass the values in ALSHeadr table into
the sproc.


Thanx

How To Return The Result Of An EXEC From A Function

Sep 21, 2007

Hi,

I am trying to find a way to return the result of an EXEC(*sqlstring*) from a function. I can return the tsql but not the result of an execute.

This is my function:

ALTER FUNCTION [dbo].[ReturnPickItemValue]
(
-- Add the parameters for the function here
@TypeID int,
@CaseID int
)
RETURNS varchar(max)
AS
BEGIN
-- Declare the return variable here
DECLARE @RTN varchar(max)

IF(SELECT IncludeDates FROM TBL_LU_PICK WHERE PickTypeID = @TypeID) = 1
BEGIN
SET @RTN = 'SELECT PickItem I +
CASE D.IsStartDateEstimated
WHEN 0 THEN CAST(StartDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsStartDateEstimated, 0) as varchar)
END +
CASE D.IsEndDateEstimated
WHEN 0 THEN CAST(EndDate as varchar)
ELSE CAST(dbo.ReturnEstimatedDate(D.IsEndDateEstimated, 1) as varchar)
END

FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_PICK P ON P.PickItemID = I.PickItemID
LEFT JOIN TBL_PickDates D ON D.PickID = P.PickID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND P.CaseID = ' + CAST(@CaseID as varchar)
END
ELSE
BEGIN
SET @RTN=
'SELECT I.PickItem
FROM TBL_LU_PICK L
INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND CaseID = ' + CAST(@CaseID as varchar)
END


RETURN @RTN

END



Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.

I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.

Anyone with any ideas?

Exec

Jul 22, 2003

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?

Thanks

Exec In My Sp

Nov 1, 2007

I am trying to create a awkward sp, just need to know if i can do this somehow, here i piece of the code...

create procedure IM_SP_TrPreProc /*@TableName Varchar(255),*/ @SystemFileName Varchar(255)

---------------------------------------------
--Param1 = Tablename
--Param2 = Systemfilename
---------------------------------------------

as

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!!

------------------------Set Statements using @TableName Var------------------------------------------

Set @DSNo = 'select distinct DataSupplierNo from ' + @TableName
Set @SumUnits = 'select sum(Units) from ' + @TableName
Set @SumValue = 'Select sum(Value) from ' + @TableName

------------------------------------------------------------------------------------------------------

Insert into TransactionMaster([FileName],DataSupplierNo,ImportFileRecordID,FileLoadDate,
UnitsSum,ValueSum,RecordCount)

Select(@Filename),(exec(DSNo)), ................

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...

Exec Sql

Apr 28, 2006

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.

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?

EXEC

Mar 28, 2006

Hi,

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.

Pass Output Of A Function To Another Function As Input

Jan 7, 2014

I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...

I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.

Exec And Sprocs

Nov 7, 2000

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.

EXEC Dynamic Sql

May 13, 2003

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

Any idea?

How To Allow Use To Exec Xp_sendmail

Sep 20, 2004

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)

Return A Value Using EXEC

Jan 12, 2004

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:

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.
