Reseeding Temporary Tables Or Table Data Types With Identity Column
Feb 17, 2006
Hi,
I have a indexing problem. I have a sequence that needs to has a index number. I want to use a table data type and have a working sample BUT I cannot reseed the table when needed. How do I do this.
This works only for the first ExitCoilID then I need to RESEED.
Here is my code:
DECLARE
@EntryCoilCnt AS INT,
@ExitCoilID AS INT,
@SubtractedFromEntyCoilCnt AS INT
DECLARE
@ExitCoilID_NotProcessed TABLE
(ExitCoilID int)
INSERT INTO @ExitCoilID_NotProcessed
SELECT DISTINCT ExitCoilID
FROM
dbo.TrendEXIT
where
ExitCoilID is not null and
ExitCnt is null
order by
ExitCoilID
DECLARE
@ExitCoilID_Cnt_Index TABLE
(ExitCoilID int, ExitCnt int IDENTITY (1,1))
IF @@ROWCOUNT > 0
BEGIN
DECLARE ExitCoilID_cursor CURSOR FOR
SELECT ExitCoilID FROM @ExitCoilID_NotProcessed
ORDER BY ExitCoilID
OPEN ExitCoilID_cursor
FETCH NEXT FROM ExitCoilID_cursor
INTO @ExitCoilID
WHILE @@FETCH_STATUS = 0
BEGIN
INSERT INTO @ExitCoilID_Cnt_Index
SELECT ExitCoilID
FROM dbo.TrendEXIT
WHERE
ExitCoilID = @ExitCoilID
ORDER BY
EntryCoilID, Cnt
select * from @ExitCoilID_Cnt_Index
--truncate @ExitCoilID_Cnt_Index
--DBCC CHECKIDENT ('@ExitCoilID_Cnt_Index', RESEED, 1)
FETCH NEXT FROM ExitCoilID_cursor
INTO @ExitCoilID
END
CLOSE ExitCoilID_cursor
DEALLOCATE ExitCoilID_cursor
select * from @ExitCoilID_Cnt_Index
END --IF @@ROWCOUNT <> 0

declare @last int
select @last=max(empid) from Table_1

Hi,
I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.
thanks.

I have Two Database that exist on Two seperate servers. The two database contain same schema and contains tables and columns of same name. Some tables have slight differences in terms of data types or Data type lenght.
For example if a Table on ServerA has a column named - CustomerSale with Varchar (100, Null) and a table on ServerB has a column named CustomerSale with Varchar (60, Null), how can i find if other columns have similar differences in all tables with the same name and columns in the two servers.
I am using SQL Server 2005. And the Two Servers are Linked Servers
What Script can i use to accomplish this task. Thanks

I have a stored procedure which gets data from several tables in database A and inserts them into the same tables in database B. Before the inserts are done, the data in database B is removed currently by using the TRUNCATE statement.
Unfortunately these tables are now being used for replication and you cannot TRUNCATE a table used for replication.
The issue is that these tables contain an Identity column each and using DELETE means the Identity columns will be incremented from the last value each time. I do not want this to happen.
Is there any way of reseeding an Identity column without using the DBCC CHECKIDENT statement because I do not want the procedures to run under the "sa" context if a DBCC statement was to be incorporated into the stored procedure with a DELETE statement?
many thanks for help

Hi All.
I'm writing a Test Suite up for a client and currently I'm working on some Tests that assert the state of the database before and after various persistence opertions. The client uses identity columns for their keys so they are involved in the asserts. To ensure the identity values are easy to assert, each test reseeds them to the required value prior to running the persistence operation.
This works well almost all of the time except just after running the DDL to create the tables for the test suite (Which our continuous integration server does every time it runs the suite).
What looks to be happening is if a reseed call occurs for a new table that has never had an insert then the the value given to the reseed function (rf) is used as the identity value for the first insert for that table. In all other cases it's rf + 1.
I.e.
Case A)
DDL run, table never had an insert:
DBCC CHECKIDENT ('table', RESEED, 0);Then the first insert into the table will have value identity value 0
Case B)
Normal run table has had > 0 inserts.
DBCC CHECKIDENT ('table', RESEED, 0);In this case the next insert will have identity value 1
Is this behaviour correct? If it is can anybody suggest a means of detecting the special first case?
Thanks for your help

Whenever I import (or even append from another table) data to a table that has an Identity column, I get an error: Cannot insert NULL values in Identity column.
Isn't the Idenity column supposed to incement automatically without me having to provide a value? Using INSERT provides an Identity value automatically, using import however doesn't.
How can I overcome this problem? (I now delete and recreate the Identity column - really BAD practice!)
Thank you.

Hi all,
I had a problem in a stored proc when I was using table variables in SQL Server 2005. I fixed the problem by changing them to temporary tables. It works now but I really want to understand why I had to do what I did. Here's the situation:
Had a stored proc that cached quite a bit of data (100-200k records with 7 columns) into a table variable. Then, it looped through this and returned a result set. The table this procedure was querying, then caching, was highly transactional. After about 2 or 3 users were hitting the same area at once, the procedure locked. If there were no locks, it executed very fast. However, it usually timed out (due to this locking).
After researching, I see that your usually better off sticking with temp tables for large amounts of data - but the primary explanation I hear for this is that you can index it. However, it also seems that the temp table will perform read-locking as its an actual physical table, whereas the table variable will not. Therefore, because there's no locking and its entirely in memory, the table variable is often the better choice. This is confusing me though because the problem I was experiencing was some sort of locking - which I thought would have been less likely with table variables.
The only other thought I had is that the table variables (if there were several of them existing at once due to several users executing the same procedure), were causing some kind of memory limit to be hit, making the database wait until some more memory became available.
Sorry for the long post, but I'd really like to know if anyone else has had these issues and what the cause might be.
Thanks,
Mike

I've created a stored procedure that creates and uses a temporary table with a computed column. I want the computed column to call a user-defined function(UDF) that I've created. Here's an example:
CREATE PROCEDURE [dbo].[usp_Proc]
(
@Date datetime
)
AS
BEGIN
--Drop the temp table if it still exists so reports come out accurate
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[#temp]') AND type in (N'U'))
DROP TABLE #temp;
--Create the temp table for use in this stored procedure
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[#temp]') AND type in (N'U'))
CREATE TABLE #temp (
[ID] INT PRIMARY KEY IDENTITY(1,1),
[Column1] NVARCHAR (30) DEFAULT ('XXXX-XXXXX'),
[Column2] INT DEFAULT (0),
[Column3] INT DEFAULT (0),
[Column4] INT DEFAULT (0),
[Column5] as ([Column2] + [Column3] + [Column4]),
[Column6] as (dbo.FunctionName('5381', [Column1]))
)
--Insert data
INSERT INTO #temp([Column1], [Column2], [Column3], [Column4])
SELECT 'String', 1, 2, 3
--Perform more calculations
<snipped...>
SELECT * FROM #temp
DROP TABLE #temp
END
This is an example of the function:
CREATE FUNCTION [dbo].[FunctionName]
(
-- Add the parameters for the function here
@Type nvarchar(4),
@Quantity int
)
RETURNS Money
AS
BEGIN
RETURN (cast((SELECT ([Value] * cast(@Quantity as int)) FROM tblTable WHERE [ID] = @Type) as Money))
END
The error message I'm getting after I've created both the stored procedure and the UDF is when calling the stored procedure. Here it is:
Msg 4121, Level 16, State 1, Procedure usp_Proc, Line 13
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.FunctionName", or the name is ambiguous.
There's no way the function name is ambiguous. Is it even possible to do what I'm trying to do or am I just calling it the wrong way?

I have a temporary table (@tblResults) that has 4 columns that need to be populated with a calculation made from columns held within 2 other tables.
Joins
@tblResults tr JOIN dbo.MarketPrice mp
ON tr.Item = mp.Item
AND tr.[Month] = mp.[Month]
AND tr.[Year] = mp.[Year]
AND mp.[Date] BETWEEN tr.LatestStartDate AND tr.PriorEndDate
[code]....
Where the 2 dbo.MarketPrice and dbo.MillDifferentials date fields are NOT equal, the last (chronologically) dbo.MillDifferentials.Diff value should be used (or '0' if no previous value found).
so expected results where @tblResults.Id = 1:
The dbo.MarketPrice.Price value of '2014-10-29' should be combined with the dbo.MillDifferentials.Diff value of '2014-10-06' - this produces the combined Max value of 184.50
The dbo.MarketPrice.Price value of '2014-04-28' should be combined with the dbo.MillDifferentials.Diff value of '2014-04-28'
The dbo.MarketPrice.Price value of '2014-01-22' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20'
The dbo.MarketPrice.Price value of '2014-01-21' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20' - this produces the combined Min value of 111.50
The dbo.MarketPrice.Price value of '2014-01-04' should be combined with '0.00' if there is no matching or previous dbo.MillDifferentials.Diff value OR the top 1/max (most recent) dbo.MillDifferentials.Diff value if a record is found before the specified @tblResults.LatestStartDate

I'm in the process of converting a rather huge VSAM database into a set of SQL tables.
I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME).
I load the files using Import Export Data and it makes the tables with such column names as col001, col002, col003, etc... and always sets the data types to varchr(255).
And I have to cut and paste the data names from the manframe side to the server side (and the data types to.)
So, is there an easier way to do this? Or am I doomed to cut-n-paste my days away...
Thanks for any help.

Hi,
I'm just starting off in SSIS and have a question that I can't find an answer to...
I'm loading in a number of files (in separate Data Flows) and performing some transformations on them before merging them back together. What I'm not sure about is what I should be doing with the data at the end of each of my "Import Data From XXXX Flat File" Data Flows. Am I better off using OLE DB Destinations (or SQL Server Destinations) and saving this intermediate data to temporary tables, or am I better off using a Raw File Destinations and saving this intermediate data to files? Or is there, perhaps, a better option that I'm currently unaware of?
If the Raw File Destination is the way to go, then isn't there a maintenance issue with cleaning up all the files created? And will there not be a management issue to ensure that there is sufficient disc space available on the drive you are saving to?
I'm a bit confused and overwhelmed by SSIS at the moment, so any help would be much appreciated!
Thanks in advance,
Lawrie.

I have a requirement of creating nested tables in SQL server. how to create them. Just to give a background I am trying to move the RDBMS from oracle to SQL server.
Structure of tables is as follows. I have table 'Employees' with address as one of the column. I have one more table with columns Street, Town, Dist, State. When I query the table 'Employees' I should see the attribute name and values of all the columns in address table in address column.
Employees: with columns: ID, FirstName, LastName, dept, gender, dob, address
Address (Nested table): with columns : Street, Town, Dist, State
This was done in oracle using Nested tables and user defined data types. what is alternative for this in SQL server. How can I achive this requirement in SQL server.

Please help
We have an application written in MS Access. The tables are linked to a SQL 2000 database.
The problem is that sometimes insert a new record in a table freezes and times out after a while without anything has happened.
When installing the application the *mdb file is copied over to the C drive and an ODBC connection is written to the registry.
The application is used by many in the company.
We have problems on tables defined with IDENTITY columns. Can this be our problem and how can we solve it?

I am able to use user data types for creating local temporally tables in store procedures, but I receive an error at run-time about the user data type.
Msg 2715, Level 16, State 7, Procedure SP_SAMPLE_TEST, Line 4
Column, parameter, or variable #1: Cannot find data type D_ORDER_NUMBER.
The same user data type is used as parameters in several other store procedures, and they work perfect. It is also used in several table definitions.
What am I doing wrong?

I'd like to select data out of an oracle table, and UPDATE a sybase table. So far I've got as far as the following:
1. create a package
2. add 2 connection managers, set retainsameconnection=true on both just to be sure.
3. add an executesql command which creates a temporary table
create table #temp_wm ( instru_id int)
4. add a dataflow task with:
i) an oledb source with a select statement: "select instru_id from mytable"
ii) an oledb destination with open rowset: #temp_wm
added an external column called instru_id in the inputs and outputs tab
when i run, the create temp table task work, the select works, but the insert into fails. If I change the select statement to:
"select instru_id from mytable where 1=0" it all executes fine.
So everythings copacetic as long as i don't need to actually insert any real records = brilliant!
1. HAS ANYONE OUTTHERE SUCCESSULLY USED SSIS TO INSERT DATA INTO A SYBASE TEMPORARY TALBE - MAYBE ITS JUST NOT POSSIBLE??
2. Any idea how I can fix my setup?
I'm usign Sybase ASE OLE DB Drivers
Note: i also tried ## temp tables, no difference.
This is the error output.
[OLE DB Destination [255]] Error: An OLE DB error has occurred. Error code: 0x80004005.
[OLE DB Destination [255]] Error: The "input "OLE DB Destination Input" (268)" failed because error code 0xC020907B occurred, and the error row disposition on "input "OLE DB Destination Input" (268)" specifies failure on error. An error occurred on the specified object of the specified component.

I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types. For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything. I guess I could walk through the interface and try different data types, but if a list exists, that would be better.

When replicating a table which has an identity column I get the error: "Procedure cp_insert_tblname expects parameter @C1, which was not supplied.". The stored procedure appears to be called without any parameters so my insert stored procedure does not work. I know I'm missing something basic here!! Do I have to add the field names when telling replication to use a custom stored procedure. If not, how do arguments get passed to my SP, as globals somehow?
Any info greatly appreciated!!
