Using SQL Server 2005. I have a stored prod that uses a temp table. I need to test at the start of the prod to see if the temp table is there. Using the following code at the start of my prod, but does not run.
IF exists(select * from ##TO_STATUS_TBL) DROP TABLE ##TO_STATUS_TBL
What is the best way to check and/or drop the temp table. Thank you, David
hello!! i am using a couple of temp tables for a select statement. i need to drop the tables only if they exist before using them, because if i don't drop, then i will get this error:
There is already an object named '#Tmp01' in the database.
and if i try to drop the tables for the first time i run the query, then i will get an error saying that i cannot drop a table that doesn't exist.
i have tried using this sentence:
IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp01') DROP TABLE #Tmp01 IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp02') DROP TABLE #Tmp02 IF EXISTS (SELECT * FROM sysobjects WHERE type = 'U' AND name = '#Tmp03') DROP TABLE #Tmp03
but it only seems to work with normal tables, since temp tables are not found in sysobjects.
What is the best way to drop a temp table if it exists? I am looking something similar to this: if exists (select top 1 * from #TableName) then drop #TableName else end
due to unavoidable reasons i had to use a ## temp table in a SP,
ie i had to dynamically create a table whose (number of)columns i come to know at runtime..
if i do thi ::set @sql = 'create #table....select some columns _ append varchar(10)'
then insert into #temp....temp is not valid here..so i used ##temp
now i need to explicitly drop it...also in catch block , i need to make a provision for droping it incase of an error in runnin proc...some kind os IF EXISTS drop ##temp.... as i dont know if it'll be created by that time or not..how do i do it..there is ofcource no entry in sysobjects....where is the entry for temp tables...tempdb dosent have system tables..!!
I have a query that's in development that uses several temp tables. In order to test the query repeatedly while it's being written I have the following code at the beginning to discard the temp tables. This allows the query can recreate the temp tables when called in the code. if object_id('tempdb..#temp1') is not null drop table #temp1 if object_id('tempdb..#temp2') is not null drop table #temp2 if object_id('tempdb..#temp3') is not null drop table #temp3 if object_id('tempdb..#temp4') is not null drop table #temp4 if object_id('tempdb..#temp5') is not null drop table #temp5
Even though this works, it takes multiple lines of code. One of my queries has to drop 12 temp tables, thus 12 lines of code. I have been experimenting with looping the above as follows:
declare @n as nvarchar(3), @table as nvarchar(10)
set @n = 1 while @n <= 5 begin
set @table = '#temp'+@n
if object_id('tempdb..#temp'+@n) is not null drop table @table
set @n = @n + 1 end
Unfortunately, the above does not work. It gives this error message: Server: Msg 170, Level 15, State 1, Line 5 Line 5: Incorrect syntax near '@table'.
I have also tried: declare @n as nvarchar(3), @dropstmt as nvarchar(25)
set @n = 1 while @n <= 5 begin
set @dropstmt = 'drop table #temp'+@n
if object_id('tempdb..#temp'+@n) is not null @dropstmt
set @n = @n + 1 end
This does not work either. It gives this error message: Server: Msg 170, Level 15, State 1, Line 5 Line 5: Incorrect syntax near '@dropstmt'.
Hi,I found this SQL in the news group to drop indexs in a table. I need ascript that will drop all indexes in all user tables of a givendatabase:DECLARE @indexName NVARCHAR(128)DECLARE @dropIndexSql NVARCHAR(4000)DECLARE tableIndexes CURSOR FORSELECT name FROM sysindexesWHERE id = OBJECT_ID(N'F_BI_Registration_Tracking_Summary')AND indid 0AND indid < 255AND INDEXPROPERTY(id, name, 'IsStatistics') = 0OPEN tableIndexesFETCH NEXT FROM tableIndexes INTO @indexNameWHILE @@fetch_status = 0BEGINSET @dropIndexSql = N' DROP INDEXF_BI_Registration_Tracking_Summary.' + @indexNameEXEC sp_executesql @dropIndexSqlFETCH NEXT FROM tableIndexes INTO @indexNameENDCLOSE tableIndexesDEALLOCATE tableIndexesTIARob
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.
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
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
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.
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.
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.
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.
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?
which one is smarter, where there is no indexing on the table which is really simple table delete everything or recreate table. I got an argument with one of my coworker. He says it doesnt matter i say do delete. Any opinions.
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?
Hi everyone, I'm fairly new to sql and right now I am struggling with a script. I am trying to extract data from a normal table into a temporary table, update it in the temporary table, then put it back into the normal table. I'll display my code, let me know what you think, any suggestions are appreciated. Thanks a lot.
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.
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?
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?
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: Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield2" could not be bound. Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield3" could not be bound. Msg 4104, Level 16, State 1, Line 2 The multi-part identifier "tempdb.dbo.#temp_table.tempfield4" could not be bound.
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'
