here's an example of what I am trying to do.
--Exec Database.Employees
--Use Database
--Go
--Create PROCEDURE AEM.TempTable
--AS
--BEGIN
--Select * into #emptemp From Database.Employees
--End
--Select * From #emptemp
Is something like this possible? I can get the EXEC to run the "Select * into #emptemp From Database.Employees" statement, but when I try to use the temp table it doesnt see it.
Let's say that I have a stored proc that is assigned to a service broker queue and is constantly running while it waits for messages in said queue. When a message comes in on the queue, the stored proc creates a table variable based off of the contents of the message and performs various operations with the data. Since the stored proc is constantly running, do the contents of this table variable ever truly get emptied? Should I be deleting the contents of the table variable at the end of the operation to ensure that stale data doesn't persist?
View 5 Replies View RelatedI've recently started a new position and our production box. Contains a procedure that uses 30 + temp tables. I'm currently not in a position to change this as it's production and I would have to be granted a window to re-design.
However the tempDb is showing some strange activity.
If a table is created #CarrierService (CarrierServiceID,DeliveryZoneID,CollectionZoneID) for example
Once the procedure is called It will appear in the tempDB with the session info appended as expected
#CarrierService________________________________________________________2C78E45A
However once the session has ended the above table will get dropped and a new one created
#2C78E45A, I now have 7000 of these different Tables in the TempDB
When I Interrogate this using
SELECT o.name, o.create_date,o.modify_date , c.Name,C.Column_Id
FROM tempdb.sys.Objects o
Inner join tempdb.Sys.Columns c
ON o.object_id =c.Object_ID
WHERE o.type ='U'
I get the Following results
name create_date modify_date object_id name
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CarrierServiceId

For finding size values of temp database:
select * from sys.master_files -
size column value here is 1024 for .mdf,size here for .ldf is 64
select * from tempdb.sys.database_files -
size column value here is 3576 for .mdf,size here for .ldf is 224
Why is there a difference and not the same. size columns in the above 2 tables for temp db's do they represent different values ?
1) "Deferred compile" recompile event occurs because of deferred name resolution. In other words, an object referred to in the statement does not exist at compile time. Later, when the object does exist, it requires a recompile of the statement so that it can create an optimal execution plan. One example of when a deferred compile will occur is if a temporary table is used in a batch and does not exist when the first statements in the batch are compiled.

do you have a general rule of thumb for breaking a complex query into temp tables? For someone who is not a sql specialist, a query with more than a few table joins can be complex. So a query with 10+ table joins can be overwhelming for someone who is not a sql specialist.
One strategy is to break a problem into pieces so to speak by grouping together closely related tables into temp tables and then joining those temp tables together. This simplifies complex SQL and although not as performant as one big query it's much easier to understand. So do you have a general rule of thumb as far as a threshold for the number of joins you include in a query before you break the query into temp tables?
Hi,
I need to pass a table name and id to a function and return a row count
I need to use EXEC or SP_EXECUTESQL to run dynamic SQL
It wont work in functions. Following is my function
alter FUNCTION [dbo].[GetRowCount] (@TblName NVARCHAR(25) , @Itemid INT)
RETURNS INT
AS BEGIN
DECLARE @RowCnt INT
set @RowCnt = 0
DECLARE @Sqlstring nvarchar(2000)
set @Sqlstring = 'SELECT @RowCnt = COUNT(*) FROM ['+ @TblName +'] WHERE Itemid = '+ convert(varchar(10),@Itemid)
EXEC @Sqlstring
RETURN @RowCnt
END
while executing this I get the following error ....
"Only functions and extended stored procedures can be executed from within a function." and "Incorrect syntax near the keyword 'EXEC' "
does anyone have any ideas of this ?
Thanks.

I've below value in a column with data type - TEXT

This text value has some special characters in it. and I could not paste the exact value as this text box is not allowing me to do so. So, for reference I've attached a screenshot (Capture.png) of the value.
I want to fetch last two values from this text i.e. 25 and 06. (It can be anything like 56R,06T but will be the last two values separated by comma)...
I have an exec() statement in a stored procedure:
Code:
exec('insert into foo

Getting this error when running the stored procedure:
Code:
Could not locate entry in sysdatabases for database 'bar'. No entry found with that name.
How do I force SQL Server to recognize the function's name?
Thanks.
I'm using MS SQL Server 2005.
I want to simulate a table, using a Multi-statement Table-Value User-Defined Function, but I need the function build the SQL statement from scratch each time so I can dynamically define values like the table it references. The only way I know how to run the query after it has been defined in this manner is to run an EXEC command. However I'm getting an error basically saying that the EXEC command is off limits in a User Defined Function.
The Exsact Error is:
>[Error] Script lines: 1-108 ------------------------
Invalid use of side-effecting or time-dependent operator in 'EXECUTE STRING' within a function.
Is there some way to get around this limitation of User Defined Functions. Or perhaps a way to simulate the functionality of Multi-statement Table-Value User-Defined Functions in a Store Procedure, specifically the ability to run where statements, or transform the data on the fly without re-writing the Stored Procedure every time.
The code I’m trying to run is below.
(Note: The code works as a stored procedure, so I'm sure that the core of the statment is correct)

View 1 Replies View RelatedHi all,
Looking at BOL for temp tables help, I discover that a local temp table (I want to only have life within my stored proc) SHOULD be visible to all (child) stored procs called by the papa stored proc.
However, the following code works just peachy when I use a GLOBAL temp table (i.e., ##MyTempTbl) but fails when I use a local temp table (i.e., #MyTempTable). Through trial and error, and careful weeding efforts, I know that the error I get on the local version is coming from the xp_sendmail call. The error I get is: ODBC error 208 (42S02) Invalid object name '#MyTempTbl'.
Here is the code that works:SET NOCOUNT ON
CREATE TABLE ##MyTempTbl (SeqNo int identity, MyWords varchar(1000))
INSERT ##MyTempTbl values ('Put your long message here.')
INSERT ##MyTempTbl values ('Put your second long message here.')
INSERT ##MyTempTbl values ('put your really, really LONG message (yeah, every guy says his message is the longest...whatever!')
DECLARE @cmd varchar(256)
DECLARE @LargestEventSize int
DECLARE @Width int, @Msg varchar(128)
SELECT @LargestEventSize = Max(Len(MyWords))
FROM ##MyTempTbl
SET @cmd = 'SELECT Cast(MyWords AS varchar(' +
CONVERT(varchar(5), @LargestEventSize) +
')) FROM ##MyTempTbl order by SeqNo'
SET @Width = @LargestEventSize + 1
SET @Msg = 'Here is the junk you asked about' + CHAR(13) + '----------------------------'
EXECUTE Master.dbo.xp_sendmail
'YoMama@WhoKnows.com',
@query = @cmd,
@no_header= 'TRUE',
@width = @Width,
@dbuse = 'MyDB',
@subject='none of your darn business',
@message= @Msg
DROP TABLE ##MyTempTbl
The only thing I change to make it fail is the table name, change it from ##MyTempTbl to #MyTempTbl, and it dashes the email hopes of the stored procedure upon the jagged rocks of electronic despair.
Any insight anyone? Or is BOL just full of...well..."stuff"?

Somewhere i read..that in SQL Server...usage of Built-in Functions on Columns, makes query optimizer to ignore indexes on that column...!
So lets say we have table EMP with Emp_id and Emp_Name....
Also we have Non-Clustered index on Emp_Name.
So following query would NOT use Non-Clustered index on Emp_Name column.
SELECTLEFT(emp_name, 3) as emp3
FROMdbo.EMP
Is this true? i am using SQL Server 2008.
I have a dynamic sql which uses Pivot and returns "technically" variable no. of columns.
Is there a way to store the dynamic sql's output in to a temp table? I don't want to create a temp table with the structure of the output and limit no. of columns hence changing the SP every time I get new Pivot column!!
what are some common techniques for ensuring an isolated temp table scope? For example, if 2 different sprocs happen to crud a temp table with the same name? I'm guessing that big SQL shops establish a standard for this early on to avoid conflicts between sprocs.
