Hi, I wanna know is there any advantage of perf gain when using Derived Tables over Temp Tables, advice me which one is better to use. Can I create Indexes and Insert/Update records into Derived Tables.

When I import data I first import it from a text file into a table ofit's own, then using some logic insert some of the records into apermanent table.I am considering having the table that the data from the text file isplaced in being there all the time and just clearing it out after I dothe import, or creating it and after using it then drop it, or using atemporary table.What are the advantages of a temporary table as opposed to creating aregular table and dropping it after use?

In a table-valued UDF, does the UDF use a table variable or a temp table to form the resultset returned?
i am inserting something into the temp table even without creating it before. But this does not give any compilation error. Only when I want to execute the stored procedure I get the error message that there is an invalid temp table. Should this not result in a compilation error rather during the execution time.?
--create the procedure and insert into the temp table without creating it.
--no compilation error.
CREATE PROC testTemp
AS
BEGIN
INSERT INTO #tmp(dt)
SELECT GETDATE()
END
only on calling the proc does this give an execution error
I don't know if it's a local issue but I can't use temp table or table variable in a PP query (so not in a stored procedure).
Environment: W7 enterprise desktop 32 + Office 2012 32 + PowerPivot 2012 32
Simple example:
declare @tTable(col1 int)
insert into @tTable(col1) values (1)
select * from @tTable
Works perfectly in SQL Server Management Studio and the database connection is OK to as I may generate PP table using complex (or simple) queries without difficulty.
But when trying to get this same result in a PP table I get an error, idem when replacing table variable by a temporary table.

View 2 Replies View RelatedIf on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?

Hello,
I am receiving the following error:
Column name or number of supplied values does not match table definition
I am trying to insert values into a temp table, using values from the table I copied the structure from, like this:
SELECT TOP 1 * INTO #tbl_User_Temp FROM tbl_User
TRUNCATE TABLE #tbl_User_Temp
INSERT INTO #tbl_User_Temp EXECUTE UserPersist_GetUserByCriteria @Gender = 'Male', @Culture = 'en-GB'
The SP UserPersist_GetByCriteria does a
"SELECT * FROM tbl_User WHERE gender = @Gender AND culture = @Culture",
so why am I receiving this error when both tables have the same
structure?
The error is being reported as coming from UserPersist_GetByCriteria on the "SELECT * FROM tbl_User" line.
Thanks,
Greg.
Below is my table structure. And I am inserting data from other temp table.
CREATE TABLE #revf (
[Cusip] [VARCHAR](50) NULL, [sponfID] [VARCHAR](max) NULL, GroupSeries [VARCHAR](max) NULL, [tran] [VARCHAR](max) NULL, [AddDate] [VARCHAR](max) NULL, [SetDate] [VARCHAR](max) NULL, [PoolNumber] [VARCHAR](max) NULL, [Aggregate] [VARCHAR](max) NULL, [Price] [VARCHAR](max) NULL, [NetAmount] [VARCHAR](max) NULL,
[Code] ....
Now in a next step I am deleting the records from #revf table. Please see the delete code below
DELETE
FROM #revf
WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2
[Code] ...
I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:
SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],
[Code] ....
If my above statement is wrong . Where i can improve here? And actually i am getting 4 rows difference.
Hello
Is it possible to insert data into a temp table with data returned from a stored procedure joined with data from another table?
insert #MyTempTable
exec [dbo].[MyStoredProcedure] @Par1, @Par2, @Par3
JOIN dbo.OtherTable...
I'm missing something before the JOIN command. The temp table needs to know which fields need be updated.
I just can't figure it out
Many Thanks!

I think this is a very simple question, however, I don't know the
answer. What is the difference between a regular Temp table
and a Global Temp table? I need to create a temp table within
an sp that all users will use. I want the table recreated each
time someone accesses the sp, though, because some of the
same info may need to be inserted and I don't want any PK errors.
thanks!!

Hi!
What is the difference in performance if I use a Temp-table or a local-table variable in a storedprocedure?
Why?
//Daniel
I want to insert the data from temp table to other table. Only condition is, it needs to sorted based on tool number and tool date. For example if we have ten records for tool number 1000, it should be order by tool number and then based on tool_dt. Both tables doesn't have any primary keys. Please find below my code. I removed all the unnecessary columns for simple understanding. INSERT INTO tool_summary (tool_nbr, tool_dt) select tool_nbr, tool_dt from #tool order by tool_nbr, tool_dt...But this query is not working as expected. Data is getting shuffled.

WE have a job that loads data from an Oralce DB into our SQL Server 2000 DB twice a day. The schedule has just changed so that now there is a possibility of having my west coast users impacted when it runs at 5 PM PST and my east coast users impacted when it runs at 7 AM EST. As a workaround, I have developed a DTS package that loads the data into temp tables instead of the real tables. IE. Oracle -> XTable_temp instead of Oracle -> XTable. The load sometimes takes about an hour to an hour and a half to load, so this solution works great, but I want to then lock the table, delete it and rename the temp table to table X. The pseudo code would be:
Begin Transaction
Lock Table XTable
Drop XTable
Alter Table XTable_temp rename to XTable
Release Lock XTable
End Transaction
Create XTable_temp
I see two issues with this solution. 1) I think if I can lock XTable that the lock would be released when the table is dropped and the XTable_temp was being renamed. 2) I can't find a command to rename a table.
Any ideas on a process that might help?

I want to pass the 'inserted' table from a trigger into an SP, I think I need to do this by dumping inserted table into a temporary table and passing the temp table. However, I need to do this for many tables, and don't want to list all the column names for each table/trigger (maintenance nightmare).
Can I dump the 'inserted' table to a temp table WITHOUT specifying the column names?
I need to decide what is better to use: global temp table ( I can't use local one) or permanent table in SQL 2000 stored procedures. I extract data from linked server table and update several tables on our server.
Those procedures scheduled to run every 3 hours.
Another question: for some reasons when I used global temp table, I wasn't able to schedule multi steps with every step executing one of the stored procedures.I think global temp tables should be visible to other stored procedures, right?
Your suggestions?

Hi All,Hope someone can help me...Im trying to highlight the advantages of using table variables asapposed to temp tables within single scope.My manager seems to believe that table variables are not advantageousbecause they reside in memory.He also seems to believe that temp tables do not use memory...Does anyone know how SQL server could read data from a temp tablewithout passing the data contained therein through memory???Is this a valid advantage/disadvantage of table variables VS temptables?
View 2 Replies View RelatedIn a previous post "Could #TempTable within SP cause lock on tempdb?" http://forums.microsoft.com/msdn/showpost.aspx?postid=2691763&siteid=1
It was obvious that we have to limit the use of #Temp table to a minimum. Let assume that some of the temp tables are really difficult to replace and we have to live with them.
Would it be easier on tempdb if the #TempTable is replaced by a table variable? Or do they all end up in tempdb?
Thanks in advance for any help.
I am trying to update a table in one database with data from a temporary table which i created in the tempdb.
I want to update field1 in the table with the tempfield1 from the #temp_table
The code looks something like this:
Use master
UPDATE [dbname].dbo.table
SET [dbname].dbo.table.field1 = [tempdb].dbo.#temp_table.tempfield1
WHERE ( [dbname].dbo.table.field2= [tempdb].dbo.#temp_table.tempfield2
AND [dbname].dbo.table.field3= [tempdb].dbo.#temp_table.tempfield3
AND [dbname].dbo.table.field4= [tempdb].dbo.#temp_table.tempfield4)
I get the following error:

Hi all,
I am querying a table in oracle, the server connection to the Oracle database is determined by a criteria. Though how can I put the results from the oracle query into a temp table ?
This is the code i'm using for the query:
DECLARE @cmd VARCHAR(500)
declare @Year varchar(25)
set @Year = '2006'
DECLARE @Link VARCHAR(100)
DECLARE @Table VARCHAR(100)
select @Link = Server from tbl_Conn where Area='Floor'
select @Table = Target_Table from tbl_Conn where Area='Floor'
SET @cmd =
'
select * from OPENQUERY
(
' + @Link + ',
''
UPDATE '+ @Table +'
SET TARGET_VALUE = '+@Value+'
WHERE Date = '+@Year'
''
)
'
EXEC (@cmd)
How do I put the executed results into a TEMP table ?
Rgds,
I have read alot of articles saying that we should use Table variable for small volume of data, Temp table for large volume of table.
However, how to determine small and large??? Willing for your comment and answer..
Hello all.
I have a temp table called #JOB which i know contains data (i can select from it and it shows about 30 rows). The problem is when i am trying to update another table with the contents of the temp table...........query analyser tells me no rows have been updated.
here is the code i am using:
UPDATE JOB
SET JOB.JOB_REF = #JOB.JOB_REF
FROM #JOB
Does anyone have any ideas where i am going wrong? Cheers in advance.

Two point to discuss
1) Temp table, variable table and derived tables,
they all seem same to me. Is there any big difference among them.
Also, if I do have the tables avaiable, so now I don't think I have to create any of the temerory tables,
since I can use the
WITh mystatement ( )
Select * from mystatmment
I think if I have to use any of the temperory tables , only time when I have to just create some tables to test some values on in it rather then using the real table in the database.
2) And not only that I use the CTE for that but for any sub query whereever apply, i would like to forget about the IN, Exit or = in the correlated queries but would use whereever I can use the "Joins"
I would like other point of view on that.
Thanks
Hi,
I have built a database for a university project, but am having trouble with the SQL syntax for inserting derived data from a calculation into a table. At present my SQL is;
INSERT INTO MemberPayment (TotalCharge) VALUES ( [Total] )
SELECT ((MileageHistory.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) + ((MileageHistory.MileageCountry * Vehicle.EmissionsPerGramUrban) * 0.05) AS 'Total'
FROM [NeuCar].[dbo].[MileageHistory] JOIN [NeuCar].[dbo].[Vehicle]
ON MileageHistory.Registration = Vehicle.Registration
JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName
WHERE Member.UserName = 'wenger1' AND (MileageHistory.[Date] >= CURRENT_TIMESTAMP - 30);
Would anybody be able to point out where I am going wrong? I would very much appreciate any advice,
Kind regards,
Chima
I got an error as follows:
Derived table 'A' is not updatable because a column of the derived table is derived or constant.
when I tried to run this query:
update A set MonthsUnbilled =99999888
FROM (select MonthsUnbilled from dbo.vw_MasterView
WHERE (RecordID =8377396)) A
This is a simplified query in order to pinpoint the culprit. I know I don't need to use a derived table if the real query is this simple.
Thanks in advance!
