Hi,
I have a table which has around 50,000 rows.
Can I delete the rows older than one year?
If no, Can I delete the last 25,000 rows (older rows) from the table?
Can you assist me with the SQL Statement to do this?
Thanks

I have a backup job that has failed.
The database size is 20.6 GB and the Transaction logs are 135MB
The amount of disk space I have left is 3.65MB. Which I know is not going to work.
However on the maintenance plan it is suppose to remove files older than 1 day.
I am wondering if a job works like this:
Step 1 create backup file
Step 2 Create Transaction Log Back up
Step 3 Delete old backup file
Step 4 Delete old Transaction log back up
Which tell me I would need to have double amount of disk space to accommodate 2 20 GB backup file and 2 135MB Transaction log file.
Is this correct??
Also is there a way that I can have step 3,4 done first.

I am using the backup task and backing up a database but want to delete all backup files older than 5 days old. I am using the file task for this and have built the path in a variable but am trying to use a wildcard for the time. I am getting illegal character in path. How can I go about this.
I currently have E:MSSQL.1MSSQLBackupdatabasename_backup_20070309*.bak in my input variable and am trying to delete the file databasename_backup_200703091532.bak
hello there,
what is the code to Delete all rows in a Table????
thanks in advance
I need to delete some specific rows in Table1
int1 must have the value 1
int2 must have the value 1
int3 must have the value 0
and now we get to the difficult part - first character in the field [Cost No] have to be different from the letter 'B'. [Cost No] have the datatype varchar(20)
I expected the code to look something like this:
DELETE Table1
FROM Table 1
WHERE ([Int1] = 1) AND ([Int2] = 1) AND ([Int3] = 0) AND ((LEFT([Cost No]), 1) <> 'B')
But I get this error message:
The left function requires 2 arguments
What am I doing wrong and what should the right code look like?
i have 6 read only tables that every night all the data gets dumped and a new updated copy of the data is copied over. the tables range from 500,000 rows to almost 4 million. i have indexes set up on the fields i use to query against. my questions are
1.since i dump all the data every night and replace it, do i need to rebuild the indexes every night or is that done after the data is reentered?
2.i want to use a fill factor on the table since it is read only, but will dumping the data every night and reinputting it have adverse affects with a fill factor?
3.should i be shrinking the database or defragging it everynight cause of my data dumps and reloads?
thanks in advance

How can I quickly delete thousands of rows in a table (SQL2000) according a query and without blowing up the log file? For instance executing the query:
Delete from transactions
WHERE transactiondatestamp < DATEADD (m,-4,GETDATE())
increases my log file to almost 6GB before job was done an normal size was re-obtained. In addition it took a long to time to get the job done.
With the command truncate table I cannot use query unfortunately but this would be faster.
Anyone has an idea?

I have an SQL tables [Keys] that has various rows such as:
[ID] [Name] [Path] [Customer]
1 Key1 Key1 InHouse
2 Key2 Key2 External
3 Key1 Key1 InHouse
4 Key1 Key1 InHouse
5 Key1 Key1 InHouse
Obviously IDs 1,3,4,5 are all exactly the same and I would like to be left with only:
[ID] [Name] [Path] [Customer]
1 Key1 Key1 InHouse
2 Key2 Key2 External
I cannot create a new table/database or change the unique identifier (which is currently ID) either. I simply need an SQL script I can run to clean out the duplicates (I know how they got there and the issue has been fixed but the Database is still currently invalid due to all these duplicate entires).
Any help would be greatly appreciated.

hi there!
I have encounter the problem when trying to delete the rows..with the error message

I was wondering if anyone had a suggestion as to how to delete duplicate rows from a table. I have been doing this:
SELECT * INTO TempUsersNoRepeats
FROM TempUsers2
UNION
SELECT * FROM TempUsers3
This way I end up with a total of four tables (the fourth table being the original Users table) and I was hoping that there was a way that I could do this all within the the original Users table and not have to create the three TempUsers tables.
Thanks,
Ron
Hi Guys!
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times
WHERE EXISTS (
SELECT 1
FROM
Users
WHERE
(A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND
((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
What gives? What am I doing wrong here?
Hi,
I export one table to Excel using Export Wizard. Second time I have used this creator I have checked option "Delete rows in destination table" because table already exists in Excel file.
During execution I get an error:
"Error 0xc002f210: Preparation SQL Task: Executing the query "DELETE FROM 'MyTable'" failed with following error: " and here is my translation from my language: "Deleting data from linked table is not supported by this version of ISAM"
I have also saved this package to a file and here is the full connection string to my Excel file:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsprzemekPulpitmyfile.xls;Extended Properties="EXCEL 8.0;HDR=YES";
Few days ago I have been using SQL2000 on the same machine and the same export was working properly.
Any suggestions?
Thanks.

I have a table 300+GB. it holds 10 years of Data. I need to delete 5 years of data and put it to another server so I can have more space.
If I delete 5 years of data, Transaction log gets so huge and size of the database even gets bigger because of the .ldf file which even gets bigger! I think I can shrink the log file and the data file. Is this the best way to do it?
I have deleted nearly 30 million rows from a table. But however when I used the sp_spaceused command to calculate the data occupied by the table I don't see any difference in the data size of the table. In fact the data has increased to few MBs after the deletion, but not much.

Hi ,
I have a scheduled job which does an text file import in my database . The data gets appended in my table every day from this import job .
Since my table is growing every day , i want to truncate the table after the data has been collected for three months i.e 90 days . The table will be empty and the new data will flow in through the import .
Any thoughts how to do it through query and schedule it ???
Thanks
I have a table with approx 5 million rows and 36 columns. It takes approx
4 minutes to delete 1 row. The table has 3 indexes in addition to it's primary key and has twelve foreign key constraints. We are still using sequel 7.
There is a backup run every night as part of the nightly maintenence that
reorg/reindexes and checks the database integrity. Any thoughts?
Thanks
Hi i'm a learner of sql,
i need help in deleting rows from a table that have multiple occurences of a value.
the table has a column named product_id , i need to find out what rows have the product_id value repeated ( i.e not distinct)
how do i do that help please.
I have an issue that I don't know how to figure out.
I have a table that has a list of files in it. This table also has GUIDs associated with each file.
Some of these files were found in the emporary internet files folder on the systems scanned.
I want to remove all rows where the file path contains emporary internet files
The problem is that there are other tables where the file GUIDs are referrenced.
So when I try this:
DELETE FROM osScanFile
WHERE (FilePath LIKE '% emporary internet files\%')
I get an error saying that "The DELETE statement conflicted with the REFERENCE constraint "blah blah blah". ...
Basically there are rows in other tables that reference the rows I'm trying to delete in this table.
So how do I get it to delete not only the rows with the search criteria in it but also all rows from all other tables where the rows are linked?
Thanks,
Terry
I have a csv file that I need to import daily into a SQL Server 2005 table. Much of the table contents could just be overwritten with the new csv file, however there are a set of Rows within the table that need to be appended to , rather than overwritten.
There is no Primary Key in the csv file that can be used.
I'm not sure this is the best approach, but what I have been trying to do, is append the entire csv file to the existing table, and then go back and delete the duplicates.
When I run the Delete, it does delete the majority of the records, but leaves a couple hundred behind. The number left behind varies with each run, can't seem to identify a pattern here. Running the Delete a second time does clean up the rows left behind in the first execution of the Delete, and gives the result I want.
Any thoughts as to why this needs to be run twice? Or is a better approach available?
Here is my code -
SELECT [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time], dupcount=count(*)
INTO temppkgactions
FROM pkgactions
GROUP BY [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time]HAVING count(*) > 1
DELETE TOP (SELECT COUNT(*) -1 FROM dbo.temppkgactions WHERE dupcount > 1 )
FROM dbo.pkgactions
DROP TABLE temppkgactions

What I'm trying to do is delete a user and all their related information within the other tables. I'm not wanting to delete the table, just one column with that user and their related information. So my Primary_Key is UserID within the table [alumni] and my three Foreign_Keys are CommentID, PhotoID, and AlbumID within the tables [comments], [photos], and [albums]. Here is some of the code that I have:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:SoderquistString %>"
DeleteCommand="DELETE FROM [alumni] WHERE [UserID] = @UserID"
SelectCommand="SELECT [UserID], [UserName], [FirstName], [LastName], [State] FROM [alumni] WHERE ([State] = @State)">
<DeleteParameters>
<asp:Parameter Name="UserID" Type="Int32" />
</DeleteParameters>
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="state" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
The users are set up in GridView form. Is there some type of DELETE command that I need to be writing that is different than the one above? I have tried adding onto the following DELETE statment:
DeleteCommand="DELETE FROM [alumni] WHERE [UserID] = @UserID
DELETE FROM [photo] WHERE [UserID] = @UserID;
DELETE FROM [album] WHERE [UserID] = @UserID;
DELETE FROM [comment] WHERE [UserID] = @UserID;
...but that doesn't work...and doesn't look right. I would really appreciate anyones suggestions or help that you may be able to provide. Thank you!

I have problem in deleting duplicate rows. I have a identity column in my table, if I try to use correlatted sub query with Delete command it gives error.
The other problem I have is I have a date column in my table and update that column with current date and time. If use a query to fetch a records on a particular day , it does not return any rows
select * from rates where ch_date >='02/11/99' and ch_date<='02/11/99'
If I use convert also there is some other problems. Is there any way to force date checkings to be done excluding time.
Thanks
This is an imaginary problem while discussing ROWID in ORACLE.
Consider a table without primary key, unique key, uniuqe index.
A row has inserted into the table many times.
I want to delete all but one dulicated rows. With any 'where' clause all rows(duplicated)
will be deleted. In ORACLE i can achieve this using ROWID as follows:
Delete from Table_name
where < all column values >
and ROWID <> ( Select max(rowid) from Table_name where < all column values > )
How can this be achieved in MS SQL Server 6.5 ?
According to Dr. Codd's Golden rules for RDBMS one is that
One should be able to reach each data value in the database by using
table name, row idenfication value and column name.
Does MS SQL Server 6.5 satisfy this requirement ?
Also How many of Dr. Codd's 13 Golden Rules for RDBMS does MS SQL Server 6.5
Satisfy? Which doesn't ?
Any discussion about Codd's Rules is welcome.

I have two tables. Table 1 contains a distinct ID(3,4,5). Table 2 contains multiple ID's(3,3,3,3,3,4,4,4,5,5,5). I want to be able to use a join. If an ID is found in table 2, remove all entries of it. Any ideas? Thanks...
delete b.id
from table1 a join table2 b on a.id = b.id
In my database, I have a table "tbl_c_extract" that consists of 4 columns that look the following. I'm looking at a daily batch of around 4000 records, of which 150 are likely to be duplicates.
Emp_No varchar(255), Proprietary_ID varchar(255), LeaveDateActual datetime
123456, E123456, 2014-09-27 00:00:00.000
213832, E123456, 2099-12-31 00:00:00.000
213836, E123456, 2014-01-31 00:00:00.000
In the example above, I need to remove 2 of the entries, leaving only the one that with the maximum leave date. In this case, those without a leave date have the 2099 entry.
Using CTE works exactly as I want it to, however SQL Server Agent doesn't seem to like the use of CTE..
Code:
WITH CTE (Proprietary_ID, LeaveDate, RN)
AS
(
SELECT Proprietary_ID, LeaveDate,
ROW_NUMBER() OVER(PARTITION BY Proprietary_ID ORDER BY Proprietary_ID, LeaveDate) AS RN
FROM tbl_c_extract
)
DELETE
FROM CTE
WHERE RN > 1

View 4 Replies View RelatedHi,
I've deleted a bunch of rows from my table.. So far about 500k from a 9 million row table.. This table is hit frequently
I think maybe my indexes are a mess? Its so slow every page is timing out .. im now urgently trying to figure something out to resolve ..
ive done UPDATE STATISTICS on the table .. now its probably best I run some command on the indexes directly?
Any help very much appreciated.. !!!
