Modify Table Structure Via Stored Procedure(?)

Jun 9, 2008

Our ERP vendor is helping us migrate from one version of their product to another. In the new version, they have added some columns and changed a few data types in several existing tables.

They sent us a list of the modifications that were necessary, which we did (painstakingly) by hand. But, for other reasons the update failed and we have to start anew.

This got me thinking: is there any way to do this kind of update via a script/stored procedure? I don't have their exact changes handy, but it was stuff like the table "inmast" needs a column of varchar(50) called "lotc" added to it, and the "intime" table needs the datatype of columns "Mon" "Tue" "Wed" changed from text to varchar(50), stuff like that.

Is it possible to do stuff like that in a SP?

Joining Two Tables To Modify A Tree Structure With More Information

Jul 30, 2007

I’m trying to create a modified catalog tree out from two tables in sql

The catalog is created from two tables.

Table 1 has the lowest level and is showing the connection with the item and the lowest ItemGroup. It also shows the connection with the MainCatalog

MainCatalogId, ItemGroupId, ItemId

Example data:

(sorry for the tabs that won't work)
MainCatalogIdItemGroupIdItemId
715063823
715073824
715093825
715093826

The catalog structure is in table 2. Here are the connections between the different


ItemGroupId, ParentId

Example data:

ItemGroupIdParentId
15061365
15071365
15091364
13641066
13651066
1066NULL

To be able to use create the tree structure and not getting the result set to big, I need it to look something like this:

ItemGroupIdItemIdLevel 2 level 3Level4
1506 3823136510667
1507 3824136510667
1509 3825136410667
1509 3826136410667

I have tried many ways, but I’m not getting the result I want.

Hope this was understandable, and that someone has an idea if this is manageable


Thanks :)

Make Sql Function To Modify Data Like Sql Procedure To Improve Code Structure And Readability.

Aug 27, 2007

Now Sql Function can not modify data as Sql Procedure like other database, it's very troublesome at most case!
in most case, Sql Function is used to improve code structure then it can be maintanced easy! BUT only because it can not modify data, there are 2 troublesome way:

1. Make all callers in the path from Sql Functions to Sql Procedure. and the coder will cry, the code will become very
confusional , and very difficult to maintance.

2. Divide the Sql Function into a thin CLR wrapper to call a Sql Procedure, can only use another connection, BUT can not be in the same transaction context And the code is ugly and slow.

You should not give limitation to Sql Function, should just limit the using context of Sql Function!

The sql code is more difficult to read and maintance than norm code(C#), then the improving code structure and readability should be one of your most important task, that's why microsoft!

Database Automatically Creates Xxx_Temp Table While Modifying / Updating Table Structure .

Dec 16, 2007

Hello friends,

I am new to the SQL Server 2005 development.

From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.

Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,

"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".

where xxx is the table name.

I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.

Thanks in advance. Any help will be appreciated.

Aug 14, 2015

Below is my table structure. And I am inserting data from other temp table.

CREATE TABLE #revf (
[Cusip] [VARCHAR](50) NULL, [sponfID] [VARCHAR](max) NULL, GroupSeries [VARCHAR](max) NULL, [tran] [VARCHAR](max) NULL, [AddDate] [VARCHAR](max) NULL, [SetDate] [VARCHAR](max) NULL, [PoolNumber] [VARCHAR](max) NULL, [Aggregate] [VARCHAR](max) NULL, [Price] [VARCHAR](max) NULL, [NetAmount] [VARCHAR](max) NULL,

[Code] ....

Now in a next step I am deleting the records from #revf table. Please see the delete code below

DELETE
FROM #revf
WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2

[Code] ...

I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:

SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],

[Code] ....

If my above statement is wrong . Where i can improve here? And actually i am getting 4 rows difference.

Modify Table To Turn OFF Autoincrement ID

Oct 4, 2013

I've a table with an ID column, it is an auto increment id column that increases by 1.

ID
--
9724
9725

When my webhost restarts SQL, or some other random act of God, this ID jumps by 1000. Today it leapt from 9725 to 10725, which just doesn't work for me. It results in my having to upload the last known good copy of the database.

My host says they can't change the 1000 row buffer, MS apparently doesn't deem this an issue, and I'm quite frustrated. I used to be able to modify certain settings in SQL since I was using an SQL 2008 database under SQL Management Console but since my host upgraded to 2012, and I'm running XP, there is no forward compatibility and many options are no longer possible (eg. modifying a column, now it has to be done via clicking query and entering a SQL command rather than just right clicking on the column)

So long story made short... is there a way to modify my table (named "places") to turn OFF the autoincrement Id and perform a simple means to figure out the next possible value?

example:
id, place, locstion, gps, v2, v3, v4, comment
================================================
9720, Bill's House, Toronto, 43.4453, y, n, c, This was a good place to eat
9721, Dime a Dozen, Cambridge, 42.4453, n, e, d, A good place to take photos

I'd have to pull the highest value of ID (+1 to it) and then do a standard INSERT into places (id, place, location, gps, v2, v3, v4, comment) values (9722, etc...)I guess my concern is if the autoidentity is turned off, will SQL allow a new value to be entered via INSERT? I'm also using the @@identity to find the last known ID when I want to direct the user to the entry that they've just created and I don't know what that # is just yet. Would the @@identity still work?

ALTER / MODIFY / OverWrite Table?

Apr 10, 2008

Hi all I was wondering how to do an ALTER command on a Table but without specifying Column Names but rather attempting to overwrite the Table itself with the new fields specified? For instance if I have Table_1 consisting of the following fields:

IDFirstNameSurname

Then use the following ALTER command:




Code Snippet
ALTER Table Table_1
(
ID Int,
FirstName VarChar(50)
)
This would then drop Surname from the Table and leave only ID and FirstName inside it. Is this possible? I have been searching google but can't seem to find what I am looking for.

Thank for comments + suggestions. Regards, Onam.

Read, Modify Table (locking) Question

Feb 3, 2006

I am quite new to MS SQL, and I want to read rows from a todo table, andwhen a row has been processed, I want to delete that row.Ages ago in MySQL I would probably have locked the table, select, processa row, delete a row, unlock the table.I have been reading through the documentation from MS SQL, but it's notclear what exactly I should do.Since I want to lock only one table in the select (the others just providedata, and are not modified), what's a good solution?--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

Open Table With Query To Modify Data

Jul 23, 2007

In Enterprise Manager, I would right click on the table, choose Open Table and Query where I could select specific records and (most importantly) could alter data in a record by deleting the text, adding or over-typing.



In 2005 Server Management Studio I just cannot figure how to do this. I'm guessing that I need the 'Script Table as' option but then what?



I have managed to open selected data using the New Query and then Design Query in Editor, but the results only appear in a kind of view form and I cannot seem to alter any of the data entries, I get dotted lines around the selected field.



Please help, it seemed so much easier in 2000!

How can I setup a table structure for the diagram shown in the attached bitmap?

1) I need to create a product using labour and materials.
2) I need to create hardware using labour and materials.
3) I need to be able to include some hardware in some products.
4) Some materials in the product are made of a culmination of materials. E.G., Concrete is made of sand, stone, and cement.

Any suggestions?

So far I have :


USE NORTHWIND

Product varchar(50)
)

go

ALTER TABLE tbProducts
ADD CONSTRAINT tbProducts_pk PRIMARY KEY (ProductID)
GO

Manpower int NULL DEFAULT(0),
Hours float NULL DEFAULT(0.0)
)

GO

ALTER TABLE tbProductLabour
ADD CONSTRAINT tbProductLabour_pk PRIMARY KEY (fkProductID, fkLabourCode)

GO

ALTER TABLE tbProductLabour
ADD CONSTRAINT tbProductLabour_Product_fk FOREIGN KEY (fkProductID)

GO

CREATE TABLE tbHardware (

Hardware varchar(50)
)

go

ALTER TABLE tbHardware
ADD CONSTRAINT tbHardware_pk PRIMARY KEY (HardwareID)
GO


CREATE Table tbHardwareMaterials (
fkHardwareID int NOT NULL,
fkMaterialID int NOT NULL,
Quantity Float NOT NULL
)

GO
ALTER TABLE tbHardwareMaterials
ADD CONSTRAINT tbHardwareMaterials_pk PRIMARY KEY (fkHardwareID, fkMaterialID)
GO

ALTER TABLE tbHardwareMaterials
ADD CONSTRAINT tbHardwareMaterials_fk FOREIGN KEY (fkMaterialID)
REFERENCES tbMaterials (MaterialID)

GO
ALTER TABLE tbHardwareMaterials
ADD CONSTRAINT tbHardwareMaterials_Hardware_fk FOREIGN KEY (fkHardwareID)
REFERENCES tbHardware (HardwareID)
GO

CREATE TABLE tbHardwareLabour (
fkHardwareID int NOT NULL,
fkLabourCode char(2) NOT NULL,

)

GO

ALTER TABLE tbHardwareLabour
ADD CONSTRAINT tbHardwareLabour_pk PRIMARY KEY (fkHardwareID, fkLabourCode)

REFERENCES tbLabour (LabourCode)

GO

ALTER TABLE tbHardwareLabour
ADD CONSTRAINT tbHardwareLabour_Product_fk FOREIGN KEY (fkHardwareID)
REFERENCES tbHardware (HardwareID)
GO



This table structure does not include anything about accounts and item 4) making materials from 1 or more other materials (E.G., Concrete).

Any hints how to incorporate these outstanding items?

Structure Table ..

Dec 13, 2007

I'm new in creating tables. and I was asked to create table(s) to capture information using SQL server 2005 (express edition)

please read below and share your thoughts and opinions o what's the efficient and best way to structure the tables.

I need to capture user's input daily and every hour, text can be from 20-100 characters, and my company is expecting to have 50,000+users in the future...Also the hrs's text can be stored for max 120 days, after that data would be deleted from the table(s)
An example is put all together, (not sure if it is the right and efficient way)

An example is put all together, (not sure if it is the rigth and effectient way) and if database would support that.. and if it will be fast enougth to search for data

(table structure) - (example with 3 users)
userId | timestap | message
1 12/12/2007 10:00 some message
1 12/12/2007 11:00 some message
1 12/12/2007 12:00 some message
1 12/12/2007 13:00 some message
1 12/12/2007 14:00 some message
2 12/12/2007 10:00 some message
2 12/12/2007 11:00 some message
3 12/12/2007 12:00 some message
3 12/12/2007 13:00 some message

Best Structure For The Table

Feb 11, 2008



Hi,
I have one field "Status" with 15 different types of values. Like 1, 2, 3, 4 .. 15.
Now this Status field contains the values like this:
Id Status
1 1,2
2 3
3 1,2,3
4 13,15

What is the best way to organize this information in SQLServer table?
My idea is Create one table with the following volumns: ID, Status1, Status2, Status3, ... Status14, Status15.

Now the above data look like this:
Id Status1 Status2 Status3 ... Status13 Status14 Status15
1 1 1 0 0 0 0
2 0 0 1 0 0 0
3 1 1 1
4 0 0 0 1 0 1

So, In future If they add new column they can easily add column like status16.
And status table look like this
Status
StatusID Description
1 a
2 b
..
15

Thanks in advance

Transactional Repln,how To Modify The Width Of A Column Of A Table Which Is Replicated

Aug 3, 2006

Hi All,
Is there a way by which we can modify the width of a column of a table which is being replicated without touching the ongoing transactional replication? This is for MSSQL2000 Transactional Replication.

I know (and successfully tried) that we can add a column to a table and that gets propaged to the replicate database and indeed the added column gets reflected there. How to add a column? sp_repaddcolumn or Right Click on the Publication-Properties and it shows a button to Add a Column.

This is what I have tried for modifying the width of a column of a table participating in Transactional Replication from varchar(10) to varchar(100)

MH (source) -> MH1 (Replicate)

The column €œcol1€? had width of varchar(10) and this was altered to varchar(100).


insert into MH..test_mh values(4,'abcdeabcdefff')

select * from MH1..test_mh

exec sp_dropsubscription @publication = N'MH', @article = N'test_mh', @subscriber = N'UKPBDRMTST2', @destination_db = N'MH1'
go

exec sp_droparticle @publication = N'MH', @article = N'test_mh'
go

alter table test_mh alter column col2 varchar(100) null OR

MH1..sp_help test_mh

exec sp_addarticle @publication = N'MH', @article = N'test_mh', @source_table = N'test_mh'
go

exec sp_addsubscription @publication = N'MH', @article = N'test_mh', @subscriber = N'UKPBDRMTST2' , @destination_db = N'MH1'
go


Needless to say, help would be apreciated -

Question On Table Structure

Jun 24, 2007

 All,On my aspx page i have 2 sets of checkboxlists, each with a number of items and i am storing that info in my db. currently i have my table set up this way: InfoID--PK autoUserID-intCheckBoxList1ID-intCheckBoxList2ID-int  So a user can select more than 1 item in each checkbox, so this table will contain multiple user-ids and each id from the respective checkboxes. My question is, is there a better way to store this data? I hope this is clear, any input would be greatly appreciated.Thank you.
