I am just learning about temp temps using Iteration, how do I clear the contents of the #temp table because when I re-run the query I get the following error:
Msg 2714, Level 16, State 6, Line 6
There is already an object named '#mytemp2' in the database.
I have a real table with an identity column and a trigger to populate this column.
I need to import / massage data for data loads from a different format, so I have a temp table defined that contains only the columns that are represented in the data file so I can bulk insert.
I then alter this table to add all the other columns so that it reflects all the columns in the real table. I then populate all the values so that this contains the data I need.
I then want to insert into the real table pushing the data from the temp table, however this gives me errors stating that the query returned multiple rows.
I specified all the columns in the insert grouping as well as on the select from the temp table.
ANY thoughts / comments are appreciated. This is beginning to drive me nuts.

I have a Database that is set to Simple Recovery mode.
It is not clearing the log and the transaction log is growing.
I thought that it would clear the log upon checkpoint?
How can I force the Transaction Log to clear since NO-TRUNCATE is no longer available?
I am using MSSQL 2000 and trying to debug a stored procedure that has a #temp table in it. I am using the .NET SQL debugger and I would like to display or view the contents of the #temp table while debugging. Does anyone know how to do this?
View 1 Replies View RelatedHaving issues with a table clearing out properly which is causing problems in the program.
By design there should only be one row in this table which updates with the most current record. However on this one system the table does not clear/update like it is supposed to, and instead starts adding multiple rows.
I have tried truncating the table but the problem does not resolve itself. Does anyone have any ideas as to why this might be happening?
Thanks!

View 2 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"?

I have an application that I am working on that uses some small temptables. I am considering moving them to Table Variables - Would thisbe a performance enhancement?Some background information: The system I am working on has numeroustables but for this exercise there are only three that really matter.Claim, Transaction and Parties.A Claim can have 0 or more transactions.A Claim can have 1 or more parties.A Transaction can have 1 or more parties.A party can have 1 or more claim.A party can have 1 or more transactions. Parties are really many tomany back to Claim and transaction tables.I have three stored procsinsertClaiminsertTransactioninsertPartiesFrom an xml point of view the data looks like this<claim><parties><info />insertClaim takes 3 sets of paramters - All the claim levelinformation (as individual parameters), All the parties on a claim (asone xml parameter), All the transactions on a claim(As one xmlparameter with Parties as part of the xml)insertClaim calls insertParties and passes in the parties xml -insertParties returns a recordset of the newly inserted records.insertClaim then uses that table to join the claim to the parties. Itthen calls insertTransaction and passes the transaction xml into thatsproc.insertTransaciton then inserts the transactions in the xml, and alsocalls insertParties, passing in the XML snippet

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

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.

I have tables in my database, tblNames1, tblNames2, tblNames3, and a main addresses table (currently empty). Once I've imported the address data I need to match the addressIDs in the names tables to the Primary ID in the address table based on the values of a field CompanyName (which is common to all the tables) My issue is that I have a huge CSV file with the master address information but obviously SQL server needs to assign foreign keys so the names tables can linked to corresponding rows in address table. It's a a many to 1 relationship as their will be one address with multiple name entries. All the names are normalized so everything can be matched up...
View 9 Replies View RelatedHi All,I have come up against a wall which i cannot get over.I have an sql db where the date column is set as a varchar (i know, should have used datetime but this was done before my time and i've got to work with what is there). The majority of values are in the format dd/mm/yyyy. However, some values contain the word 'various'.I'm attempting to compare the date chosen on a c# .net page with the values in the db and also return all the 'various' values as well.I have accomplished casting the varchar to a datetime and then comparing to the selected date on the .net page. However, it errors when it comes across the 'various' entrant.Is there anyway to carry out a select statement comparing the start_date values in the db to the selected date on the .net page and also pull out all 'various' entrants at the same time without it erroring? i thought about replacing the 'various' to a date like '01/01/2010' so it doesn't stumble over the none recognised format, but am unsure of how to do it.This is how far i have got: casting the varchar column to datetime and comparing. SELECT * FROM table1 WHERE Cast(SUBSTRING(Start_Date,4,2) + '/' + SUBSTRING(Start_Date,1,2) + '/' +SUBSTRING(Start_Date,7,4) as datetime) '" + date + "'"Many thanks in advance!
View 7 Replies View RelatedIn a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?
I could deploy across my environment, which is a mix of 2008R2/2012 servers, to give some information on log files. Running into a silly issue right off the bat. The table that DBCC LogInfo() conjures out of magic is different between the two. In 2012 it gained the RecoveryUnitID column. So I'm trying to write some logic to create a temp table based on which version is running. I would like to avoid a global temp table if possible. Here's what I've tried:
sp_executesql creates a table outside of the scope of my session:

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?
Using a string of IDs passed into a stored procedure as a VARCHAR parameter ('1,2,100,1020,') in an IN without parsing the list to a temp table or table variable. Here's the situation, I've got a stored procedure that is called all the time. It's working with some larger tables (100+ Million rows). The procedure passes in as one of the variables a list of IDs for the large table. This list can have anywhere from 1 to ~100 IDs passed to it.
Currently, we are using a function to parse the list of IDs into a temp table then joining the temp table to get the query:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] .....
The problem we're running into is that since this proc gets called so often, we sometimes run into tempDB contention that slows this down. In my testing (unfortunately I don't have a good way of generating a production load) swapping the #table for an @table didn't make any difference which makes sense to me given that they are both allocated in the tempDB. One approach that I tried was that since the SELECT query is pretty simple, I moved it to dynamic SQL:
CREATE PROCEDURE [dbo].[GetStuff] (
@IdList varchar(max)
)
AS
SET NOCOUNT ON
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
[Code] ....
The problem I had there, is that it creates an Ad Hoc plan for the query and only reuses it if the same list of parameters are passed in, so I get a higher CPU cost because it compiles a plan and it also causes the plan cache to bloat since the parameter list is almost always different. Is there an approach that I haven't considered that may get the best of both worlds, avoiding or minimizing tempDB contention but also not having to compile a new plan every time the proc is run?
Everytime I run the load packages that I have built into the MDS staging the tables, in MDS_Staging, get cleared down and then repopulated. When the MDS database gets new data it appends it and does not clear down the data that is already in the database and is there fore hold duplicate rows.
Is there a way of truncating the tables in the MDS database before populating again with the new data from the MDS_Staging database so as to not hold duplicate rows?

Now, a couple of problems, after the table is created and populated, I cannot find it in my list of tables, even after "refreshing".
I checked to ensure that it exists using the query analyzer and it does so I know the table is being created.
Also, I cannot see the table using crystal reports, connecting etc...... Can I not access a temporary table from 3rd party applications? I have crystal reports 7.0 professional.
Any ideas?

Hey,
I am in the process of modifying some stored procedures that currently do not use temp tables. For this modification I am required to make the stored procedures use temp tables. There are several UDF's within this stored procedure that will need to use the temp tables, and this is where in lies the problem. Does anyone know of a work around that would allow UDF's to use temp tables, or does anyone know of alternate methods instead of temp tables that wouldn't involve too much change?
Thanks
