well i have 2 table one name detcom and another entcom stored in DB1 the key for both to join on is lets say A, B, C . I need to check if there are records based on the key A, B, C of both table where C EQUALS to '80_300_113' and if there are delete them and then grab data from another
database named DB2 on same server (same instance) wich contains the same tables entcom and detcom and insert all the data from those tables into the same tables in DB1 based on the key and where C = '80_300_113'
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table. The makeid and orderdate belong to the OrderDetails table. The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
I have 3 tables, with this relation: tblChats.WebsiteID = tblWebsite.ID tblWebsite.AccountID = tblAccount.ID
I need to delete rows within tblChats where tblChats.StartTime - GETDATE() < 180 and where they are apart of @AccountID. I have this select statement that works fine, but I am having trouble converting it to a delete statement:
SELECT * FROM tblChats c LEFT JOIN tblWebsites sites ON sites.ID = c.WebsiteID LEFT JOIN tblAccounts accounts on accounts.ID = sites.AccountID WHERE accounts.ID = 16 AND GETDATE() - c.StartTime > 180
I need to delete records from one table base on criteria from another table. The example below from the Northwind database shows exactly what I want to do. I want to delete the records from the employee table who a terrorityID of 30346 in the EmployeeTerritories table.
Can someone tell me how to write a delete statement that will delete the rows returned from the following SQL Statement? The sql statement will return one employee name. I would lke to delete that one employee from the employee table and I haven’t been able to figure out how to do it.
////////// Sql Statment SELECT dbo.EmployeeTerritories.EmployeeID, dbo.EmployeeTerritories.TerritoryID FROM dbo.EmployeeTerritories INNER JOIN dbo.Employees ON dbo.EmployeeTerritories.EmployeeID = dbo.Employees.EmployeeID WHERE (dbo.EmployeeTerritories.TerritoryID = N'30346') ////////// end of sql statement
What is the logic of the below DELETE statement?It deletes all records where the file_modified column value is smaller then the maximum value in the same column, but not crystal clear how...
delete a from Staging a left join (select max(file_modifieddate) as file_modifieddate from Staging) b on a.file_modifieddate = b.file_modifieddate where b.file_modifieddate is null
I have a table with a large number of records that I need to delete, before attempt to perform the delete I also archived the records to another table.
So I need to delete all of these selected records stored in the archive table from the main table. I can now reference all the records that qualify for the delete in the main table by performing a join on the archive table like so:
select * from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
So all the records check out to be the ones I'd like to perform a delete on but I just can't figure out how to perform a delete of the records with little or no change to the existing query.
Obviously something like this won't work:
delete from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
Though it would be nice if it did.:D
So my question is how would I use the existing query with some modification to delete only the records that this query returns. I've tried selection of records in the main table based on the existing records in the archive table but it can return a higher number of records than what I know is expected. I actually need the join specified to be in place to do it.
In SQL Server 2000/2005 (not CE) I can use the following T-SQL statement to delete orphaned rows from a table:
DELETE GroupsMembers FROM GroupsMembers LEFT OUTER JOIN Groups ON GroupsMembers.GroupID = Groups.ID WHERE Groups.ID IS NULL
SQL Server CE does not seem to support combining the JOIN statement with the DELETE statement. Is this correct? If yes, is there any alternative statement that could be used to accomplish the same thing?
Hi,I would like to delete a record from a table on the condition that a corresponding ID is located in another table, ie. deleting an email message if the user ID is listed as a recipient in a recipient table etc. Here is my SQL statement: DELETE FROM id_email_message WHERE (id_message IN (SELECT id_message FROM recipients WHERE id_user = 324) AND message.id_message_status = 2) OR (id_message IN (SELECT id_message FROM message WHERE id_owner = 324 and id_message_status = 2)) The problem is the multiple select statements paired with the delete statement is too much overhead for the server and I always get a timeout server error (at least that's what I'm guessing, the error page and tracing isn't much helpful). Is there a more efficient way to do this?Thanks.Eitan
Hello there... I'm creating a ASP.net Web Application and storing all my data in SQL database.I'm trying to create a Stored Procedure to Delete info from a table:- I have 3 tables: A, B and C: A's primary key is aID and has no foreign key B's primary key is bID and has 1 foreign key: aID (linking this table to table A); C's primary key is cID and has 1 foreign key: bID (linking this table to table B);- As you can see, all 3 tables are linked (A to B and B to C)I want to be able to DELETE all info from C only by giving aID, is this possible in SQL? I can retrieve the info easily through a SELECT statement and using an INNER JOIN (*). I also know how to do solve this by coding it in C# but I'd have to create some unnecessary variables and more than 1 Stored Procedure when it's probably possible to do all in one!* SELECT cID FROM C INNER JOIN B ON B.bID = C.bIDWHERE A.aID= whateverIf anyone knows the solution to my problem, please don't hesitate :p Thanks,SuperJB
hi, i want to delete some records from my table if there is more then 150 records (it should always be max 150records, it can be less and then it shouldent delete anything), so when it goes over to 151 records i want to delete the oldest record, so i get the new record + 149 old records, is there a simple way to do this?
When does the DELETE statement physically deletes the records? For example, if I execute the DELETE statement and in the middle of the execution I understand that it is wrong. What will happen if I stop it? Will it delete the records partially? I think the deletion happens when the full statement is done but need an expert answer. Thank you.
Hi what do i need to add to this stmt to delete the result ? --------------- select ct_cust1_text01,ct_address,ct_cust1_text09,count(*)from TABLE_NAME group by ct_cust1_text01,ct_address,ct_cust1_text09 having count(*) > 1 ---------
i have tried delete * from TABLE_NAME where (select...)
Hello I am trying to delete a row from one table and I expected it to also be removed from the subsequent child tables, linked via foreign and primary keys. However, when I tried to delete a row in the first table I saw this error: DELETE FROM [dbo].[Names_DB]WHERE [LName_Name]=N'andrews' Error: Query(1/1) DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_LName_Name'. The conflict occurred in database 'MainDB', table 'Category_A', column 'LName_Name'. I went to the very last table in the sequence and I was able to delete the row without problems, but it did not effect any of the other tables. Please advise. I need to make many changes in these tables, should I use a trigger instead, if so what is the code to trigger each table? I am new to triggers. Thanks Regards Lynn
Hi! I am deleting some records from the database and at the same time inserting them into a new table. I am doing all this with sql querries. How can that be done with triggers. Basically on the delete, i'd like to insert the affected records. Thanks! James
Hey guys... I am trying to tidy up my code a bit and have one SQL command (Sub class) to call when needing to insert, update, delete and select. I have got one class I am testing with that delete from a table support_ticket and then calls RunSQL() again to delete the corresponding tickets in Support_Reply. however it only seems to want to delete from one table at a time...as i commented out the first sql and it worked and the second fires...but if the first one is active it doesnt fire. Do anyone on the forum know why this has happened?
Sub DeleteUserTicket(sender as Object, e as EventArgs) Dim strSQL1 = "DELETE FROM Support_Ticket WHERE (TicketID = " & txtticketID & ")" RunSQL(strSQL1) strSQL1 = "DELETE FROM Support_Reply WHERE (TicketID = " & txtticketID & ")" RunSQL(strSQL1) End Sub 'One class to run the sql statements for the entire page this will reduce in repetitve code as well as reduce code size Sub RunSQL(strSQL) Dim objCmd As SqlCommand Dim sqlConn = New SqlConnection(strConn) objCmd = New SQLCommand(strSQL, sqlConn) objCmd.Connection.Open() 'Check that the rows can be deleted if not then return a error. Try
objCmd.ExecuteNonQuery() response.redirect("ticketsystemtest2.aspx") Message.InnerHtml = "<b>Ticket " & txtticketID & " Closed</b> <br/>" Catch ex As SqlException If ex.Number = 2627 Then Message.InnerHtml = "ERROR: A record already exists with " _ & "the same primary key" Else
Message.InnerHtml = "ERROR: Could not update record, please " _ & "ensure the fields are correctly filled out <br>" & ex.Message & " " & ex.Number Message.Style("color") = "red" End If End Try objCmd.Connection.Close() sqlConn = nothing objcmd = nothing End Sub
One of our developers just deleted a ton of records- is there any way we can recover this data? (we can't use a backup since a ton of changes were made since we last backed up)
i am having problem running a simple delete statement against a table. it just hangs is there anything i should look at? the table has 4 primary keys and the index makes up of the 4 keys and ideas?
i viewed the delete statement with the execusion plan and this is what i saw.
delete -> index delete/delete -> sorting the input -> table delete/delete -> Top -> Index scan.
SELECT * FROM relations INNER JOIN paths ON relations.path = paths.path_id WHERE (paths.links = '161') AND (relations.node1 = 162) OR (paths.links = '161') AND (relations.node2 = 162) OR (paths.links = '162') AND (relations.node1 = 161) OR (paths.links = '162') AND (relations.node2 = 161) OR (paths.links LIKE '162%') AND (relations.node1 = 161) OR (paths.links LIKE '%162') AND (relations.node2 = 161) OR (paths.links LIKE '161%') AND (relations.node1 = 162) OR (paths.links LIKE '%161') AND (relations.node2 = 162) OR (paths.links LIKE '%161;162%') OR (paths.links LIKE '%162;161%') ORDER BY relations.node1
Don't pay attention to the 161 and 162 things, is just test data, now my problem is that I want to transform that into a DELETE statement, but I can't find the right way to do it, so far I managed to do something like:
PHP Code:
DELETE relations FROM relations INNER JOIN paths ON relations.path = paths.path_id WHERE (paths.links = '161') AND (relations.node1 = 162) OR (paths.links = '161') AND (relations.node2 = 162) OR (paths.links = '162') AND (relations.node1 = 161) OR (paths.links = '162') AND (relations.node2 = 161) OR (paths.links LIKE '162%') AND (relations.node1 = 161) OR (paths.links LIKE '%162') AND (relations.node2 = 161) OR (paths.links LIKE '161%') AND (relations.node1 = 162) OR (paths.links LIKE '%161') AND (relations.node2 = 162) OR (paths.links LIKE '%161;162%') OR (paths.links LIKE '%162;161%')
But that would delete only from the relations table and not from the paths table. I need to delete from both tables.
I need to delete the following records (from enrollment_fact):
SELECT a."STU_SID", a."SCHOOL_YEAR", a."DATE_SID", a."LOC_SID" FROM "dbo"."ENROLLMENT_FEX2" b, "dbo"."LOCATION_DIM" c LEFT OUTER JOIN "dbo"."ENROLLMENT_FACT" a on c."LOC_SID" = a."LOC_SID" WHERE b."LOC_KEY" = c."LOC_KEY" and a."DATE_SID" between b."MIN_DATE" and b."MAX_DATE"
This is the approach (excuse the misuse of the concat function, but you get the idea)
DELETE FROM "dbo"."ENROLLMENT_FACT" WHERE CONCAT (a."STU_SID", a."SCHOOL_YEAR", a."DATE_SID", a."LOC_SID") IN ( SELECT DISTINCT CONCAT (a."STU_SID", a."SCHOOL_YEAR", a."DATE_SID", a."LOC_SID" ) FROM "dbo"."ENROLLMENT_FEX2" b, "dbo"."LOCATION_DIM" c LEFT OUTER JOIN "dbo"."ENROLLMENT_FACT" a ON c."LOC_SID" = a."LOC_SID" AND a."DATE_SID" BETWEEN b."MIN_DATE" AND b."MAX_DATE")
Hi,My question is : CREATE TABLE t1 (c1 INTEGER, c2 INTEGER, c3 DECIMAL(15,0 )) INSERT INTO t1 VALUES (1, 2, 3.0) How can i define a SQL commend will cause C1 to be decremented each time a row is deleted from the T2 table? Thanks !
I have a rather tricky SQL delete query I’m trying to perform, preferably without cursors. I have the following data set, where I want each of the first changes to the status.
So given the above data set I would want to delete the following IDs: 3, 5, 6, 7, and 8. As they not the first in order. The problem is that while I can get isolate and save first instance of each status (in this case 1, 2, and 4), I can’t get the what I want. Is there a SQL way of accomplishing this.
i have problem to discuss regarding delete statement. Due to the bad design of application i have added some duplicate values in table. i have fixed the issue for new insert but how to delete my old bad id. i have table having three column,
ID1 ID2 ID3 101 2 3 102 2 3 103 2 4 104 3 4
in my case first two record are duplicate i want to keep first one and delete the other.
I have duplicate rows of data with the exact same data, for multiple sets of data.For example,
1 Fred Flintstone 1 Fred Flintstone 2 Barney Rubble 2 Barney Rubble etc...
If I use the delete and where command, it will delete both rows and I want to keep one of them. I don't want to copy down each one and re insert as there are too many columns for each one and there are too many rows also.I was thinking of a delete row-number command in a where statement. but tried multiple forums and its not working.
i am creating an insert based on a select statement -- i need to delete the row from the select statment table after it has been inserted
something like
insert into table_insert(value1, value2) (select table_exclude_id, value1, value2 from table exclude) delete from table_exclude where table_exclude_id in "the select statement"
