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!
I have the following tables in my DB
Employee table - This table has EmployeeID, Name, DOB.
EmployeeDesignation table - 1 Employee can have many designations with each having an effective date. There is no flag to indicate which among multiples is the current entry. You can only figure it out by the newest/oldest EffectiveDate. I want to get the most recent and the oldest for each employee.
EmployeeSalaryHistory table - Structure/Design is similar to EmployeeDesignation table. I want to get the starting salary and current salary for each employee.
I want my query to output me the following fields...
EmployeeID
EmployeeName
EmployeeDOB
EmployeeStartingDesignation
EmployeeCurrentDesignation
EmployeeStartingSalary
EmployeeCurrentSalary
Here is a piece of code to generate sample data sets
DECLARE @Employee TABLE (EmployeeID INT, EmployeeName VARCHAR (100), EmployeeDOB DATE)
INSERT @Employee VALUES (101, 'James Bond', '07/07/1945'), (102, 'Tanned Tarzan', '12/13/1955'), (103, 'Dracula Transylvanian', '10/22/1967')
DECLARE @EmployeeDesignation TABLE (EmployeeID INT, Designation VARCHAR (100), EffectiveDate DATE)
INSERT @EmployeeDesignation VALUES (101, 'Bond Intern', '01/01/1970'), (101, 'Bond Trainee', '01/01/1975'), (101, 'Bond...James Bond', '01/01/1985')
[Code] ....
Currently, I have a query to get this done which looks as below. Since I have more than 8K employees with each having multiple Designation and Salary entries, my query is taking forever.
selecte.EmployeeID, e.EmployeeName, e.EmployeeDOB,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate) EmployeeStartingDesignation,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate Desc) EmployeeCurrentDesignation,
[Code] ....
Hi seniors
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.

Hello:
Need some serious help with this one...
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.
Thanks!

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
DELETE FROM Broker_Rates
WHERE (Broker_Rates.BID <> Broker.BID)
Thanks

View 3 Replies View RelatedI have a database that keeps track of pledges, scheduled reminders, and payments.
A user sets up a pledge and then sets up a schedule for reminders to be sent for each payment of the pledge.
Pledge table - PledgeID,PledgeDate,PledgeAmount,etc...

Hi,
I have a base query that will return the ID, StartDate and Code for all IDs. I SELECT only for Codes 5 and 9. For most of the IDs I return a record for both a Code 5 and Code 9. They will have different dates however. How could I select from this base query one record for each ID with the oldest date? The items in yellow are the ones that I would want to return to a report in SSRS. Is there a way to put this data in a temp table and read through it to compare IDs and grab the one with the older date?

I may have one or several files in a folder that act as source files.
How do I loop through the folder, picking the oldest dated file according to its 'Date Modifield' attribute.
Do I have to use a Script Task or similar as I can't seem to find a way to do it with normal tasks.
If so, does anyone have example code.
Thanks

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 a table that I need to delete the oldest date. I thought I could just do an update statement saying...
Delete T_BreakDown
where Date = MIN(Date)
But that doesn't work.
'****************************************************************************
Cmd.CommandText = "Drop Table Raj"
Cmd.ExecuteNonQuery()
Cmd.CommandText = "Select * Into Raj From XXX"
Cmd.ExecuteNonQuery()
'**************************************************************************
This generates error that Table already exist.
If Wait 1 sec then execute statement then it works fine.
Thanks in Advance

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.
Any ideas on what I am doing wrong here?
I have this table:
with actividades_secundarias as (
select a.*, r.Antigo, r.Novo, rn = row_number()
over (PARTITION BY a.nif_antigo, r.novo ORDER BY a.nif_antigo)

((select
[Code] ....
I want to make a delete statement like this:
select * into #table1 from actvidades_secundarias where rn>1
Delete from act_secundarias where act_secundarias.nif_antigo = #table1.nif_antigo and act_secundarias.cod_cae = #table1.cod_cae
But it seems that I cant delete like this.
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.

Using sqlServer management studio 2005
My Tables are something like this:
--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]
-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]
--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?
Thanks

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

ds = gDatabase.ExecuteQuery(" select Table_Name from Information_schema.Tables where Table_type='TABLE'")

For Each dr In ds.Tables(0).Rows
Datatable = dr.Item("Table_name")
Cmd = "Delete from [" & Datatable & "]"
gDatabase.ExecuteNonQuery(Cmd)

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!

Good evening everyone,I have a problem with deleting a record in a table.
I have the table:

I have inserted many Employees and when i do select they work fine.
The problem is with Delete e.g. i want to delete the Employee with Eid = 12 i do:
Delete from Employee where shop_id = '12'
and it says
