Transact SQL :: Select 1000 Rows At A Time From / Into A Large Temp Table?
May 12, 2015
I am using SQL SERVER 2008R2, not Denali, so I cannot use OFFSET FETCH Clause.
In my stored procedure, I am doing a SELECT INTO #tblTemp FROM... Working fine. This resultset is going to be used in an SSIS package which will generate a pipe-delimited .txt file... Working fine.
For recoverability sake, I am trying to throttle back on the commit chunks to 1000 rows per commit until there are no more rows. I am trying to avoid large rollbacks.
Q: Am I supposed to handle the transactions (begin/commit/rollback/end trans) when the records are being inserted into the temp table? Or when they are being selected form the temp table?
Q: Or can I handle this in my SSIS package for a flat file destination? I don't see option for a flat file destination like I do for an OLE DB Destination (like Rows per batch, Maximum insert commit size).
Iam attempting to generate files containing more than 1000 characters per line by outputting the results of a stored procedure via osql to a flat file. Osql (and isql) appear to force a newline after 1000 characters, even when specifiying a -w2000 parameter.
I have also tried to output the results of the stored procedure via DTS and this appears to do the same thing!
Does anybody know how to prevent osql (or isql) from forcing the newline?
I have a temp table with the following columns and data
drop table #temp create table #temp (id int,DLR_ID int,KPI_ID int,Brnd_ID int) insert into #temp values (1,2343,34,2) insert into #temp values (2,2343,34,2) insert into #temp values (3,2343,34,2)
[Code]....
I use the rank function on that table and get the following results
select rank() over (order by DLR_ID,KPI_ID,BRND_ID ) Rown,* from #temp
I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)
I want to create index for hash table (#TEMPJOIN2) to reduce the update query run time. But I am getting "Warning!
The maximum key length is 900 bytes. The index 'R5IDX_TMP' has maximum length of 1013 bytes. For some combination of large values, the insert/update operation will fail". What is the right way to create index on temporary table.
Update query is running(without index) for 6 hours 30 minutes. My aim to reduce the run time by creating index.
And also I am not sure, whether creating index in more columns will create issue or not.
Attached the update query and index query.
CREATE NONCLUSTERED INDEX [R5IDX_TMP] ON #TEMPJOIN2 ( [PART] ASC, [ORG] ASC, [SPLRNAME] ASC, [REPITEM] ASC, [RFQ] ASC,
In my database table has auto Identity file which is (1,1) But Its Increasing 1000 Some time 100 I don't Understand why It is happening in my every table.
IF NOT EXISTS (SELECT TOP 1 1 FROM dbo.syscolumns WHERE id = OBJECT_ID(N'dbo.Employee) and name = 'DoNotCall') BEGIN ALTER TABLE [dbo].[Employee] ADD [DoNotCall] bit not null Constraint DoNot_Call_Default DEFAULT 0 IF ( @@ERROR <> 0 ) GOTO QuitWithRollback END
It just takes a LOT of time in SQL Server Management studio. I have to cancel the query and cancelling takes a whole lot time. I am using SQL Server 2008.
I'm trying to fill a temp table whose columns are the same as another table plus it has one more column. The temp table's contents are those rows in the other table that meet a particular condition plus another column that is the name of the table that is the source for the rows being added.
Example: 'permTable' has col1 and col2. The data in these two rows plus the name of the table from which it came ('permTable' in this example) are to be added to #temp.
Data in permTable col1 col2 11, 12 21, 22
Data in #temp after permTable's filtered contents have been added
I have a table set of records. Its contains some customerID,SportsGoods,Price in different datetime. I want to add customer spent. If crossed 1000 means i have to show purchase time when it is crossed 1000. I need query without while and looping.
I have a few hundred users, maybe a dozen or two active at any given time, accessing the same database via ASP. The database has many tables, one being a very large orders table with a few million records, in which I have created a view against. A view only because I need to allow the user to filter quite extensively against the results. The users typically only need to view records for the last 30 days and results for each user might be five thousand records or less.
My question is this. Would I be better off writing each user's resultset to a temp table for that user's session and allow the filtering and sorting by the user go against that temp table and increase my hardware requirements to accomodate that. Possibly to the point of creating a database cluster. OR would I be better off leaving it as is where each users uses the same view.
FYI...each user may need visibility to only a hand full of fields, but over all the view must maintain many fields.
Any thoughts on this would be greatly appreciated. Thanks in advance.
I need to take a temporary table that has various times stored in a text field (4:30 pm, 11:00 am, 5:30 pm, etc.), convert it to miltary time then cast it as an integer with an update statement kind of like:
Update myTable set MovieTime = REPLACE(CONVERT(CHAR(5),GETDATE(),108), ':', '')
how this can be done while my temp table is in session?
So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?
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.
I have a table with a couple hundred billion records (sql server 2005). When I do a select count(*) from tblx -- it takes this side of forever. Is it possible to count partitions and then add them up to make it faster?
How I could improve the performance for count(*) of this huge table. Note: if the partition idea sounds viable -- what would that look like?
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
i have temp table name "#TempResult" with column names Memberid,Month,Year. Consider this temp table alredy has some rows from previuos query. I have one more table name "Rebate" which also has columns MemberID,Month, Year and some more columns. Now i wanted to insert rows from "Rebate" Table into Temp Table where MemberID.Month and Year DOES NOT exist in Temp table. MemberID + Month + Year should ne unique in Temp table
I have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2 select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.
USE [BB] GO /****** Object: Trigger Script Date: 24/07/2015 3:41:38 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
I pulled some examples of using a subquery pivot to build a temp table, but cannot get it to work.
IF OBJECT_ID('tempdb..#Pyr') IS NOT NULL DROP TABLE #Pyr GO SELECT vst_int_id, [4981] AS Primary_Ins, [4978] AS Secondary_Ins,
[code]....
The problems I am having are with the integer data being used to create temp table fields. The bracketed numbers on line 7-10 give me an invalid column name error each. In the 'FOR', I get another error "Incorrect syntax near 'FOR'. Expecting '(', or '.'.". The first integer in the "IN" gives me an "Incorrect syntax near '[4981]'. Expecting '(' or SELECT". I will post the definitions from another effort below.
I wanted to insert the result-set of a Exec(@sqlcommand) into a temp table. I can do that by using:
Insert into #temp Exec(@sqlcommand)
For this to accomplish we need to define the table structure in advance. But am preparing a dynamic-sql command and storing that in variable @sqlcommand and the output changes for each query execution. So my question is how to insert/capture the result-set of Exec(@sqlcommand) into a temp table when we don't know the table structure.
I have an Access app. that I am migrating the DB portion (queries, tables) to SQL server. I need to create a temp table that lasts as long as the user has the Access FE app. open. Idea is that the temp table stores the user's parameters (used for filtering data entry forms and report). The parameters allow the app. to only show the user his data (cannot view other users data). The SP shown below works OK, it creates a ##Temp table and updates it with the parameters sent by Access FE app. The issue I am having is that as soon as the SP finishes the ##Temp table is removed. I thought of using a regular table, but, I am currently testing this migration in my local SQL server instance, as soon as I move the database to production environment, then users will not be able to create tables as permissions are only read/write.
USE [Work_Allocation] GO /****** Object: StoredProcedure [dbo].[spUser_Parameters_update] Script Date: 9/30/2015 12:27:42 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[spUser_Parameters_update]
We have upgraded our SQL 2008 server to 2012 last month. i've noted since then that many tables that have auto increment primary key bigint field increases by 1 like it should, then for some reason it jumps up by 1000 or even 10000? i have seed adn auto increment set to 1 but doesnt effect it. Is there anything that could be causing the next value to jump that much?
i need to add a datetime column to an exisitng table that has like 1.2 million records and its being accessed frequently but i cant afford to stop the db at all
whenever i do : alter table mytable add Updated_date datetime
it just takes too long and i have to stop executing the query after a couple of mins I am running sql express 2005 sp2. db size is over 3 gb but still under the 4 gb limit
can u plz advice on how to add this column. its urgent!!
The following batch does not compile. It works for real tables but not temp tables. I need to get this to work. Any ideas? Thanks.
code ------------------- IF 1 = 1 --IF CONDITION BEGIN SELECT * INTO #TEMP FROM TABLE1 END ELSE BEGIN SELECT * INTO #TEMP FROM TABLE2 END -------------------- Error Msg Msg 2714, Level 16, State 1, Line 7 There is already an object named '#TEMP' in the database. --------------------
Below is a simplified table & dataset to illustrate a problem I'm experiencing with a more complex one.
Code Block
create table #test( recno smallint PRIMARY KEY, value decimal (18,2))
insert into #test values (1, 3.57) insert into #test values (2, 5.32) insert into #test values (3,6.29) insert into #test values (4, 9.25) insert into #test values (5, 0.84)
Method 1: I tried inserting rows from #test into a temp table (#table) as follows
Code Block
declare @n as nvarchar(3) set @n = 1 while @n <= (select count(recno) from #test) begin exec (' insert into ##table select *, originalrecno = (select recno from #test where recno = '+@n+') from #test' ) set @n = @n + 1 end However, this yields an error message:
Code Block
Server: Msg 208, Level 16, State 1, Line 2 Invalid object name '##table'. Note - you can comment out the insert into ##table line above to view the results that I'm trying to put into ##table.
Method 2: next I tried explicitly creating ##table & rerunning the loop containing the insert
declare @n as nvarchar(3) set @n = 1 while @n <= (select count(recno) from #test) begin exec (' insert into ##table select *, originalrecno = (select recno from #test where recno = '+@n+') from #test' ) set @n = @n + 1 end This worked - it inserted the data from the select statements in the loop into ##table.
create table #datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) ); insert into #datatable exec ('select * from datatable where id = 1') select * from #datatable
I still want to retrieve the data and present it in the software's presentation layer but I still want to remove the temp table in order to reduce performance issue etc.
If I paste the code DROP
TABLE #datatable after insert into #datatable exec ('select * from datatable where id = 1')
Does it gonna work to present the data in the presentation layer after removing the temp table?
The goal is to retrieve the data from a stored procedure and present it in the software's presentation layer and I still need to remove the temptable after using it because I will use the SP many time in production phase.
