there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.
Background: Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem: There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations. Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be along the lines of: a) Remove the Foreign Key references b) Copy the table structure, and make a new temp table, adding the column c) Copy the data over d) Add the FK relations, that used to be in the first table, to the new table e) Delete the original f) Done?
The questions are: a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'. b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant? c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance] ON [dbo].[tbl_attendance] AFTER DELETE AS
[code]...
When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.
I have two tables that are related by keys. For instance,Table employee {last_name char(40) not null,first_name char(40) not null,department_name char(40) not null,age int not null,...}Employee table has a primary key (combination of last_name and first_name).Table address {last_name char(40) not null,first_name char(40) not null,street char(200) not null,city char(100) not null,...}Address table has a primary key (combination of last_name, first_name andstreet in which (last_name, first_name) reference (last_name, first_name) inemployee table.Now I want to delete some rows in Address table based on department_name inEmployee table. What is sql for this delete?I appreciate your help. Please ignore table design and I just use it for myproblem illustration.Jim
I need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).
Table1 columns are: table1Id; Name. Table2 columns include Table2.table1Id which is the foreign key to Table1.
What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?
I have contract table which has built in foreign key constrains. How can I alter this table for delete/ update cascade without recreating the table so whenever studentId/ contactId is modified, the change is effected to the contract table.
Thanks
************************************************** ****** Contract table DDL is
create table contract( contractNum int identity(1,1) primary key, contractDate smalldatetime not null, tuition money not null, studentId char(4) not null foreign key references student (studentId), contactId int not null foreign key references contact (contactId) );
I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from) Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID) Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z FROM dbo.Table2 DELETE FROM dbo.Table1 WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a FROM dbo.Table2 DELETE FROM dbo.Table1 WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.

A table was created in version 6.5 that has 2 blank spaces and a slash '/' in it's name (i.e. Item Type w/Groups). This was done in error and now the table cannot be dropped or renamed and dropped.
Does anyone know how I can delete this table? Please let me know.
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.
SQLLY challenged be gentle --Trying to create code that will drop a table using a variable as theTable Name.DECLARE @testname as char(50)SELECT @testname = 'CO_Line_of_Business_' +SUBSTRING(CAST(CD_LAST_EOM_DATEAS varchar), 5, 2) + '_' + LEFT(CAST(CD_LAST_EOM_DATE AS varchar),4)+ '_' + 'EOM'FROM TableNamePrint @testname = 'blah...blah...blah' (which is the actual tablename on the server)How can I use this variable (@testname) to drop the table?

--Foreign IDs = FID --generated IDs = GID Then I try a simple single row DELETE
DELETE FROM MyCompany.Employee WHERE EmployeeGID= 39
Well this might look like a very basic error: I get this Error after trying to delete something from Table €œEmployee€?
The DELETE statement conflicted with the REFERENCE constraint "FK_Branch_ManagerFID". The conflict occurred in database "MyDatabase", table "myCompany.Branch", column 'ManagerFID'.
Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €œBranch€? entry, basically each entry in €œbranch€? and €œEmployee€? is child of each other which makes things more complicated.
My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €œON DELETE CASCADE€? or something?
lets say i have 100 employees on Table A and I have 10 employees on Table B. I want to delete all the employees in Table A that are in Table B. Delete From TableA Where EmpNum = (Select EmpNum From TableB)The above SQL wont work but i am looking for something similar. any ideas?
In general we cannot delete a table if it refers another table. But in the process of backup and restore, we need to delete all the tables, so we have return an asp.net function...
Dim Datatable As String Dim ds As New DataSet ds = gDatabase.ExecuteQuery(" select Table_Name from Information_schema.Tables where Table_type='TABLE'") If ds.Tables.Count > 0 Then If ds.Tables(0).Rows.Count > 0 Then Dim dr As DataRow Dim da As SqlCeDataAdapter Dim Cmd As String For Each dr In ds.Tables(0).Rows Datatable = dr.Item("Table_name") Cmd = "Delete from [" & Datatable & "]" gDatabase.ExecuteNonQuery(Cmd) Next End If End If
we got an error like
"Msg 4712, Level 16, State 1, Line 1 Cannot truncate table 'Electricalworks' because it is being referenced by a FOREIGN KEY constraint. "
how to override these errors, if we have to delete all the tables. We have about 200 tables.
I have two tables; Table A id, name 101, jones 102, smith 103, williams 104, johnson 105, brown 106, green 107, anderson
Table B id, name, city, state

I need to delete records from Table A that are not in Table B. My front end is writen in .net and I am using Data Access Layer along with a Business Logic Layer for data interaction.
I have tried at least seven variations of joining, right outer join, left outer join resulting in wiping our the entire table or nothing at all; not to mention deleting the record that ought to remain and keeping the record that needs to be deleted!
In my BLL I tried to capture the rowsAffected for the deletion by using-without success.
Dim rowsAffected As Integer = Adapter.ID_Deletion(ID)
A user table in a database has somehow been marked as a system table. Is there any way, short of dropping and rebuilding the database to remove this table?
I've a table with a size of ~4G and 6million rows in SQL server 2005. Deleting all rows from it it takes closer to an hour and uses ~20G of transaction log. I wasn't able to truncate it due to FK's, but should I not be able to truncat it by disabling FKs - how can I do that? Or how can I expedite this delete because it;s annoying to let server use 20G log for 4G table. My DB recovery model is set to SIMPLE (for minimum logging)
I have a table in a SQLEXPRESS database that I read in C# app. It supposed to have only two rows but a number of fields with Float or Int type parameters. It is a tedious process to tune them all up in the app. The table is used for storage, naturally.
For some reason, I won't go into I ended up with having 3 rows in this table at this point. This third row is identical to the first one in the values of all fields. It happened because I deleted a column that made these rows not unique and after that the trouble began. Before deletion of that column I had 4 rows, then I deleted the 3rd one and row #4 moved in place of #3.
For the life of me I cannot delete this 4th row no matter what I do. It gives me an error:
No rows were deleted. Problem occured while deleting row1 (sic!, I am trying to delete row #3 in fact). The row values updated or deleted either do not make the row unique or they alter multiple rows (2 rows).
Good grief! This is why I am trying to delete this row!
It does not allow me to edit the fields to change the values to make them not unique. The same error pops up. It does not allow me to change the values of the first row which is identical to the third one.
It is not the first time this happened. I had it once or twice before. Back then I had to truncate the table and enter new values from scratch I am kind of tired of doing it.
Can someone help me with how I should set the relationship in my address tables and how they will affect the deleting of a client? So, if I have: tblClients ClientID tblClientAddresses AddressID tblClientAddressLinks AddressID, ClientID Currently I have them set as a 1-M from tblClients to tblClientAddressLinks and a 1-M from tblClientAddresses to tblClientAddressLinks If I try and delete a client and there address is shared wont this go very wrong? So here is what happens when I try and delete a client: The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClients". The conflict occurred in database "DBSQL2", table "dbo.tblcLIENTAddressLinks", column 'clientID'.The statement has been terminated. Here is what happens when I try and delete an address: The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClientAddresses". The conflict occurred in database "DBSQL2", table "dbo.tblClientAddressLinks", column 'Address_ID'.The statement has been terminated.
I need to restrict delete from one table by any user of SQL. How can we do this? This is our master table and we dont want any one to delete data from this table.
Hi, I have a database that stores monthly nameed tables for historical data, but after a time (could be 1,2,3 months or on request) I need to be able to delete the oldest table. The tbale name format is ?????_mm_yyyy. Is there a MIN statement that could work on the create date? Any T-SQL statements that would help me on my way would be great Thanka!
Is there any way to delete an unwanted row on a table with 300 or more constraints with less modifications to contraints? Or is there any other way that can remove the unwanted row without much risk? Dropping the constraints is possible but re-adding the constraints may not be possible because the create constraint statements are not known. And readding the constraints may take time because the database physical size is around 1GB... Please help
How can I erase all data from every table in a SQL Server 7.0 database and leave all constraints and relationships in tact? I'm wanting to have just the structure or frame work with no data in any table. There are over 130 tables so I need to automate this. Any Suggestions?
:confused: Urgent!! Hi there. I use MS SQL server. I would like to separate the data from one table to two tables refer to two reference tables and the following conditions:
Let say these two reference tables are called: Table A & Table B
Group A: 1. Same date in Table A & Table B 2. Same ID in Table A & Table B (ID is not unique) 3. Same name in Table A & Table B (Name is not unique)
Combine all of these three conditions for unique identifier.
I used the following SQL code to separate the required data that match the above conditions to the new table. (Code) select a.Project, a.Site, a.S_number, a.Field_ID, a.Method, a.Analyte, a.Result, a.Units, a.Qualifier, a.Dilution_Factor, a.Reporting_limit, a.Recovery_, a.Matrix, a.CAS_Number, a.Sample_Date, a.Received_Date, a.Prep_Date, a.Analysis_Date, a.Batch_ID, a.Data_Package_num_SDG, a.Lab_Sample_ID, a.Lab into APPL_union_exist from APPL_union_update a, Before_01012004_report b where a.Field_ID = b.[Field Sample] and a.Sample_Date = b.Collected and a.Analyte = b.Analyte
However, I don't know how to delete the data that copied to the new table in original table, or separate that to the new table. Wish someone can help me. Thanks a lot
