Using Variables In A Temp Table Name

May 4, 2000

I am trying to add a variable to a temporary table name. Throughout a stored procedure, I do a lot with this table. I delete, insert, update, and query this table. Is there a way to do the following without having to set the entire 'select * from ...' line as a variable? Below is what I am trying to accomplish. It all works until the select * line. Is there a way to accomplish what I am trying to do below?

Declare @table varchar(255),
@PassedID integer
set @passedID=5

set @table="test"+CONVERT(varchar(20), @passedID)

select * from @table

Thanks,
Jon

Table Variables Vs. Temp Tables

Mar 8, 2006

How do I know when to use a table variable, and when to use a temp table in my stored procedures? It seems that in most cases table variables are more efficient (in terms of execution time / CPU usage) but some of my stored procedures perform an order of magnitute better with temp tables instead.
Short of testing the stored proc both ways, how do I know what to do?
declare @Temp table
or
create table #Temp

Temp Tables Vs Table Variables

Dec 15, 2005

I am running SQL Server Best Practices on a SQL 2000database and it is recommending me to change the temptables inside SPs to table variables.I had read already in other places to use table variablesover temp tables. I also know I can't create indexes asI can on temp tables. Instead I'll have to create eithera primary key and/or a unique index on a table variable.One question I have is let's say I will be putting thousandsof records in a temp table, should i still choose a tablevariable over a temp table for this? Or is there arecommended limit where if I have to store certainnumber of records then it's better to store them ina temp table rather than a table variable? Or numberof records is not the factor to decide whether to usetemp tables or table variables?I would like to know when it's ideal or best to usetemp tables instead of table variables and vice versa.Thank you

Temp Tables Vs Temp Variables

Jul 20, 2005

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

Temp Table Vs Global Temp Table

Jun 24, 1999

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!!

Temp. Tables / Variables / Process Keyed Tables ?

Feb 22, 2008

I have 3 Checkbox list panels that query the DB for the items. Panel nº 2 and 3 need to know selection on panel nº 1. Panels have multiple item selection. Multiple users may use this at the same time and I wanted to have a full separation between the application and the DB. The ASP.net application always uses Stored Procedures to access the DB. Whats the best course of action? Using a permanent 'temp' table on the SQL server? Accomplish everything on the client side?

SQL Server 2012 :: Stored Procedures Compiles Even When There Is No CREATE TABLE For A Temp Table

Feb 11, 2015

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

INSERT INTO #tmp(dt)
SELECT GETDATE()

only on calling the proc does this give an execution error

Power Pivot :: Temp Table Or Table Variable In Query (not Stored Procedure)?

Jul 19, 2012

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.

Message: OLE DB or ODBC error. .... The current operation was cancelled because another operation the the transaction failed.

SQL Tools :: Adding Column To A Table Causes Copying Data Into Temp Table

Sep 23, 2015

If 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?

BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,

[Code] ....

The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.

Column Name Or Number Of Supplied Values Does Not Match Table Definition When Trying To Populate Temp Table

Jun 6, 2005

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.

Transact SQL :: Table Structure - Inserting Data From Other Temp Table

Aug 14, 2015

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.

I'm missing something before the JOIN command. The temp table needs to know which fields need be updated.

Transact SQL :: Insert Data From Temp Table To Other Table

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.

Rename Table After Loading Data Into Temp Table

Dec 19, 2007

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?


TIA,

A

Trigger- Dump 'inserted' Table To Temp Table

Jul 11, 2006

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?

Table Names In Stored Procedures As String Variables And Temporary Table Question

Apr 10, 2008

How do I use table names stored in variables in stored procedures?




Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000





I receive the error 'must declare table variable '@tablename''

I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.




Code Snippet

if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename




It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.

Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.

Heres the actual SQL query that produces the temporary table error.




Code Snippet
Select * into #temptableabcd from TableA

Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB

TRUNCATE TABLE TableA

Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB




The above coding produces

Msg 208, Level 16, State 0, Line 1

Invalid object name '#temptableabcd'.

Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?

Thanks for the help.

Global Temp Table Vs. Permanent Table Use

Dec 17, 2004

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?

Table Variable Versus #Temp Table

In 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?
