Here is the scenario. I'm working with two tables:
Contact1
Conthist
Contact1 contains basic contact information and conthist contains history records for those contacts. Conthist can hold many records related to a single contact1 record.
The link between the two tables is a column called accountno.
I'm trying to delete any records in conthist that have an accountno that does not exist in contact1. The queries that I've tried keep returning conthist records that do actually have a matching accountno.
I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..
I must admit I dont know all that much about SQL, which is why I hope someone can show me the light. I have a script almost finished, however I have no idea how to have it trim database entries that are older than, say, 90 days. Any ideas?
I have a table with a load of orphaned records (I know... poor design) I'm trying to get rid of them, but I'm having a brain cramp.
I need to delete all the records from the table "Floor_Stock" that would be returned by this select statement:
SELECT FLOOR_STOCK.PRODUCT, FLOOR_STOCK.SITE FROM PRODUCT_MASTER INNER JOIN FLOOR_STOCK ON PRODUCT_MASTER.PRODUCT = FLOOR_STOCK.PRODUCT LEFT OUTER JOIN BOD_HEADER ON FLOOR_STOCK.PRODUCT = BOD_HEADER.PRODUCT AND FLOOR_STOCK.SITE = BOD_HEADER.SITE WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND (PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))
I was thinking along the lines of:
DELETE FROM FLOOR_STOCK INNER JOIN (SELECT FLOOR_STOCK. PRODUCT, FLOOR_STOCK.SITE FROM PRODUCT_MASTER INNER JOIN FLOOR_STOCK ON PRODUCT_MASTER. PRODUCT = FLOOR_STOCK.PRODUCT LEFT OUTER JOIN BOD_HEADER ON FLOOR_STOCK. PRODUCT = BOD_HEADER. PRODUCT AND FLOOR_STOCK.SITE = BOD_HEADER.SITE WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND (PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))) F ON FLOOR_STOCK. PRODUCT = F. PRODUCT AND FLOOR_STOCK.SITE = F.SITE
... but Sql Server just laughs at me: "Incorrect Syntax near the keyword INNER"
I have a couple SQL tables that have been appended to daily over the last two years. There is now about 50,000,000 records in the table. Does anyone know the fastest way to delete records before a certain date to shorten these tables? Delete queries and everything else I've tried is taking way too long.
Apparently, deleting 7,000,000 records from a table of about 20,000,000 is not advisable. We were able to take orders at 8:00AM, but not at 7:59.
So, what's the best way of going about deleting a large number of records? Pretty basic lookup table, no relationships with other tables, 12 or so address-type fields, 4 or 5 simple indexes. I can take it down for a weekend or night, if needed.
DTS the ones to keep to another table, drop the old and rename the new table? Bulk copy out, truncate and bring back in? DTS to text, truncate and import back? Other ways?
Never worked with such a large table and need a little experienced guidance.
My Web Host does not provide administrative privilages to the SQL server I have access to. I would like to delete tens of thousands of records from two of my tables without writing to the Transaction Log. Is what I'm trying to do is delete these records quickly without utilizing any of the alotted space my web host has set aside for my transaction log (they give me 50 mb and I go way over that when I run a DELETE statement)
I need a sql statement to delete duplicate records.
I have a college table with all colleges in the nation. I noticed that all of the colleges were listed twice. How do I delete all of the duplicate records.
Here is my table. Colleges ------------------- schoolID - smallint NOT NULL, schoolName - varchar(60) NULL
Can someone help me out with the sql statement??? I'm running SQL Server 6.5.
Hi All, I am having one table named MyTable and this table contains only one column MyCol. Now i m having 10 records in it and all the records are duplicate ie value is 7 for all 10 records.
It is something like this,
MyCol 7 7 7 7 7 7 7 7 7 7
Now i m trying to delete 10th record or any record then it gives me error "Key column information is insufficient or incorrect. Too many rows were affected by update."
What should i do if i want only 4 records insted 10 records in my table? How do i delete the 6 records from table?
I have a problem where records in underlying tables of a dataview are being deleted (seemingly at random)
For example.
CREATE TABLE [Employee] (Id int, Name varchar(50)) CREATE TABLE [Company] (Id int, Name varchar(50)) CREATE TABLE [EmployeeCompany] (CompanyId int, EmployeeId int)
CREATE VIEW [dvEmployee] AS SELECT * FROM [Employee] INNER JOIN [EmployeeCompany] ON [Employee].[Id] = [EmployeeCompany].[EmployeeId]
CREATE TRIGGER [dvEmployeeUpdate] ON [dbo].[dvEmployee] INSTEAD OF UPDATE AS BEGIN UPDATE EmployeeCompany SET Status = INSERTED.Status FROM EmployeeCompany, INSERTED WHERE EmployeeCompany.CompanyId = INSERTED.CompanyId AND EmployeeCompany.EmployeeId = INSERTED.EmployeeId END
Because the column [Status] is a t-sql keyword, does the fact that the trigger contains the line "SET Status = ..." without saying "SET [Status] = ..." mean that I could lose records in the EmployeeCompany table?
Reason I'm asking is we have an already designed database that is littered with columns named the same as sql keywords (almost every table has a [Status] column, and there are many [Password] columns). When using a dataview on these tables, triggers exist that aren't putting the [] around these column names (the same as my dvEmployeeUpdate trigger above), and somehow we are seemingly randomly losing records. It is very rare, and they are getting completely deleted, and it seems to be the tables that contain the keyword columns and are used in dataviews with instead of triggers that don't put [] around the column names. Nowhere in any trigger or stored procedure is there a DELETE FROM on these tables, and the software running on the database uses only the data views, and doesn't directly access the underlying tables.
I've been going through all of the code adding the [], but my question is simply whether or not anyone has heard of this causing the deletion of any records, or whether there may be something else going on that I should be looking into?
help me out on this one. i have 2 text boxes in my page. user enter any number in those two text boxes. i slect that many record randomly from my main table, and put it into two another tables. now the problem is coming in how to delete those records which were randomly selected from main table in main table. for eg main table contains srNo. UswerID 1 abcd 2 trtr 3 tret 4 yghg 5 jjhj
user enters in text box1 '2' and in text box2 `1' so total of 3 random records are selected and put it into two another table say
table1 sr.no UserID 2 trtr
and table2 contains
sr.no. userid 3 tret 5 jjhj
now i want to delete these records which are sr.no 2,3,5 from the main table. how do i do it as user can enter any number in the text box.so writing multiple delete statements would not be possible. how do i write statements or help me with logic.
Hi I wanted to do a delete rows from a group of table. These tables have a common column UserID. I heard that there is something called ondelete cascade. But I don't know how to set it up and utilise it. Could someone tell me how to do it. Or point me to a tutorial which shows how to do it. Thanks
I have a database that is used to store a lot of data. We load the data on adaily basis, several thousand records per day. The Log file is not needed,so whats the best way to delete the records in it and reduce the sizeThanksDerrick
Hi, i need the suggestion here in very familiar db situation ..i have a main table and a primary key of that table is used in many other table as foreign key.If i am deleting a record in a main table,how do i make sure that all the corresponding record in the associated tables,where that foreign key is used, gets deleted too?What are my options?Thanks
Hello all, I have a DTS package set up to import a text file on a daily basis. I need to dump the data in 2 table after 7 days of the last import .this is the code that I have Delete From TblTemp date(Day(-7), CurrentStamp). But for some reason it deleting the data right after it imports it. And it doesn't delete anything out of the other table.
I have a function that opens a connection to an SQL database, issues a SELECT command, and reads the records with an OleDbDataReader. As the records are read, any that match certain criteria are deleted with a DELETE command. Simplified example code is shown below:
Dim dbCmd As OleDb.OleDbCommand = New OleDb.OleDbCommand() dbCmd.Connection = New OleDb.OleDbConnection(UserDbConnString) dbCmd.CommandText = "SELECT * FROM [User] ORDER BY UserID" dbCmd.Connection.Open() Dim reader as OleDb.OleDbDataReader = dbCmd.ExecuteReader(CommandBehavior.CloseConnection) While reader.Read() If reader("SomeColumn") = SomeCalculatedValue Then Dim dbCmd2 As OleDb.OleDbCommand = New OleDb.OleDbCommand() dbCmd2.Connection = New OleDb.OleDbConnection(UserDbConnString) dbCmd2.CommandText = "DELETE FROM [User] WHERE UserID = " + reader("UserID") dbCmd2.Connection.Open() dbCmd2.ExecuteNonQuery() dbCmd2.Connection.Close() End If End While reader.Close()
This code worked well with an MS Access database, but when I changed to SQL Server, I get a database timeout error when attempting to do the DELETE. I suspect the reason is that the connection the reader has open has the record locked so it cannot be deleted.
The SQL connection string I am using is something like this:
UserDbConnString = "Provider=SQLOLEDB; Server=(Local); User ID=userid; Password=password; Database=dbname"
The connection string I used for MS Access included the property "Mode=Share Deny None". I wonder if there is some similar way to tell SQL Server to allow editing of records that are open for reading with an OleDbDataReader.
I wrote a script to archive and delete records rom a table back in 2005 and 2009.
I can't seem to get the syntax right. Any sample script to simply archive and delete records?
This is what I have so far.
DECLARE @ArchiveDate Datetime SET @ArchiveDate = (SELECT TOP 1 DATEPART(yyyy,Call_Date) FROM tblCall ORDER BY Call_Date) --SELECT @ArchiveDate AS ArchiveDate DECLARE @Active bit

I've got a table with a unique column, "id". I've got the id values of about 300,000 records. These records need to be DELETEd from this table. Is there a way to do this in batch? I can't imagine the only way to do it is:
DELETE FROM Table WHERE id = 1 OR id = 2 OR id = 3... OR id = 300000

I am having problems with my sql merge replication. Whenever a user syncs up to my main database, most of their records are deleted instead of being merged. Or the records on the main database are inserted and it replaces the whole table with the records on the remote laptops. Is there a way to prevent this from happening? Someone please help me.

I managed to find the 'Deleting Duplicate Records' from SQLTeam.com (thanks, by the way!!).. I managed to modify it for one of my tables (one of 14).
-- Add a new column
Alter table dbo.tblMyDocsSize add NewPK int NULL go
-- populate the new Primary Key declare @intCounter int set @intCounter = 0 update dbo.tblMyDocsSize SET @intCounter = NewPK = @intCounter + 1
-- ID the records to delete and get one primary key value also -- We'll delete all but this primary key select strComputer, strATUUser, RecCount=count(*), PktoKeep = max(NewPK) into #dupes from dbo.tblMyDocsSize group by strComputer, strATUUser having count(*) > 1 order by count(*) desc, strComputer, strATUUser
-- delete dupes except one Primary key for each dup record deletedbo.tblMyDocsSize fromdbo.tblMyDocsSize a join #dupes d ond.strComputer = a.strComputer andd.strATUUser = a.strATUUser wherea.NewPK not in (select PKtoKeep from #dupes)
-- remove the NewPK column ALTER TABLE dbo.tblMyDocsSize DROP COLUMN NewPK go
drop table #dupes
Now that I've got that figured out, I need to write the same thing to fix the other 13 tables (with different column info)- and I'll need to run this daily.
Basically I've put together some vbscript that gathers inventory data and drops it into an MSDE db (sorry - goin for 'free' stuff right now). Problem is it has to run daily so that I'm sure to capture computers that turned on at different times etc which ever-increases my database 'till I bounce off the 2GB limit of MSDE.
So the question is, what would be the best way to do this? Can I put the code into a stored procedure that I can execute each day?
I have a query that is executing properly but i want to delete the results of the query. I am trying to do it but i am messing up somewhere in the syntax
Can anybody help me out with this problem? Below is the query DELETE FROM DPT_NEW_BINS WHERE( Select BIN,LEFT(ACCT_NUM_MIN,16), LEFT(ACCT_NUM_MAX,16), ISO_CTRY_CD, REGN_CD ,PROD_TYPE_CD FROM DPT_NEW_BINS o WHERE EXISTS (SELECT BIN,LEFT(ACCT_NUM_MIN,16), LEFT(ACCT_NUM_MAX,16), ISO_CTRY_CD, REGN_CD ,PROD_TYPE_CD FROM DPT_temp_NEW_BINS i WHERE o.ACCT_NUM_MIN = i.ACCT_NUM_MIN AND o.ACCT_NUM_MAX = i.ACCT_NUM_MAX))
