I want to add new primary key into existing table which already has a primary key. But,I do not want to remove the old primary key, since there are many records and the old primary key also have relationship with other table
When I am using this query:
alter table hem154
add indexNO uniqueidentifier default newid()
alter table hem154
add CONSTRAINT pk_hem154_indexNo PRIMARY KEY (PK_indexNO)
go
Note:
Hem154 ~ Table name
indexNo ~ Column Name
I get this runtime error:
Msg 1779, Level 16, State 0, Line 1
Table 'hem154' already has a primary key defined on it.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
How to add a primary key for existing column in the table
View 8 Replies View RelatedWe want to add a new int identity column as a primary key to an already existing table that has a primary key on Guid. Here is the DDL:
CREATE TABLE [dbo].[VRes](
[VResID] [uniqueidentifier] NOT NULL,
[Mes] [varchar](max) NOT NULL,
[PID] [uniqueidentifier] NOT NULL,
[Segt] [int] NOT NULL,
[code]....
Also we currently have 3 million rows on this table. Is having an integer column as identity column and primary key better or shd I consider using BigInt?
Hi everyone,How do I set a primary key on an existing column using SQL statements? I have column persID of type int in table employees. How do I correctly apply the ALTER command to change persID type to INT IDENTITY(1,1) NOT NULL? Thanks in advance
View 5 Replies View Relatedhi guys,
just a question regarding database design
i have a table with an auto-generated primary key but the problem is this:
say i have 4 records,so logically they'll be numbered 1 to 4.so the problem is whenever i delete all records and add new ones,the numbering will start from 5 and not 1 again.
how do i remedy this?
thanx

Hi all, please help. I m trying to create an "empty" table from existing table for the audit trigger purpose.
For now, i am trying to create an empty audit table for every table in a database named "pubs", and it's seem won't work.
Please advise.. Thanks in advance.
Here is my code:
Code Snippet
USE pubs
DECLARE @TABLE_NAME sysname
DECLARE @AUDIT_TABLE VARCHAR(50)
SELECT @TABLE_NAME= MIN(TABLE_NAME) FROM INFORMATION_SCHEMA.TABLES
WHERE
TABLE_TYPE= 'BASE TABLE'
AND TABLE_NAME NOT LIKE 'audit%'
AND TABLE_NAME!= 'sysdiagrams'
AND TABLE_NAME!= 'Audit'
AND TABLE_NAME = 'sales'
WHILE @TABLE_NAME IS NOT NULL
BEGIN
SELECT @TABLE_NAME= MIN(TABLE_NAME) FROM INFORMATION_SCHEMA.Tables
WHERE TABLE_NAME> @TABLE_NAME
AND TABLE_NAME = 'sales'
SELECT @AUDIT_TABLE = 'Audit'+''@TABLE_NAME''
SELECT * INTO @AUDIT_TABLE
FROM @TABLE_NAME
TRUNCATE TABLE @AUDIT_TABLE
ALTER TABLE @AUDIT_TABLE ADD UserAction Char(10),AuditStartTime Char(50),AuditUser Char(50)
SELECT @TABLE_NAME= MIN(TABLE_NAME) FROM INFORMATION_SCHEMA.Tables
WHERE TABLE_NAME> @TABLE_NAME
AND TABLE_TYPE= 'BASE TABLE'
AND TABLE_NAME!= 'sysdiagrams'
AND TABLE_NAME!= 'Audit'
AND TABLE_NAME NOT LIKE 'audit%'
END

i have 2 tables (both containing the same column names/datatypes), say table1 and table2.. table1 is the most recent, but some rows were deleted on accident.. table2 was a backup that has all the data we need, but some of it is old, so what i want to do is overwrrite the rows in table 2 that also exist in table 1 with the table 1 rows, but the rows in table 2 that do not exist in table one, leave those as is.. both tables have a primary key, user_id.
any ideas on how i could do this easily?
thanks
Hello,
I'd like to create a temporary table with the same schema as an exiting table. How can I do this without hard coding the column definitions into the temporary table definition?
I'd like to do something like:
CREATE TABLE #tempTable LIKE anotherTable
..instead of...
CREATE TABLE #tempTable (id INT PRIMARY KEY, created DATETIME NULL etc...
I'm sure there must be a simple way to do this!
Many thanks,

I am using the DTS wizard and having problems importing excel into an existing table.
Problem is that various column in excel are defined as double in the wizard but in my db table it is defined as an integer.
How do I get around this issue so the data types in excel can match up accordingly to my defined data type in my db table?
The wizard does a bad job of guessing the correct data type.
I have heard of using a staging table to import from excel and using that as my source to import into my existing table.
I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?
Code:
SELECT Student_ind.StudentFirstName, Student_ind.StudentLastName, Student_ind.[Student ID], People_tbl.[Family ID], People_tbl.FirstName,
People_tbl.LastName, People_tbl.[Parent ID]
FROM People_tbl RIGHT OUTER JOIN
Student_ind ON People_tbl.[Family ID] = Student_ind.[Family ID]
WHERE (People_tbl.LastName = @Enter_LastName) AND (People_tbl.FirstName = @Enter_FirstName)
Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.

I want to move an existing table from another.
Example
B.mdf dbo.xx to C.mdf dbo.xx
B.mdf dbo.xx has records - I created a script and install the script for C.mdf dbo.xx
C.mdf dbo.xx is empty -
All I need now is to populate the records from B.mdf dbo.xx to the empty C.mdf dbo.xx
I was telling I could do a cut and paste to copy the dbo.xx
Thank you in advance.

Hi all,I have an existing table(Several actually) that I want to add a columnor two or three. I need to have, I think, at least two columns. Onefor Created date and believe this is a no brainer in that I just addthe column and set the default to getdate(). Two, for tracking amodified date of the row of data. I want to keep it simple. What do Ido to track the modify date of a row in SQL Server 2005? Anytime anydata changes on a row update the update column? Is a trigger the onlyway to accomplish this task?Another column could be used to track who changed it. Is there a neatway to determine username, machine name, MAC address or any othermethod? I pretty wide open on this one as I am not sure what I want touse here.TIA!!!

How do you alter the table to use the new partition (I know ALTER TABLE is in there but BOL doesn't give a valid example with the move option)? I can create the partition but I want to apply it to an existing table with no partition?
Thanks
I need sql script that can generate 'Create Table' definition including primary and foreign constraints for the table already existing in SQL server 2000.
Please do not refer me to the utilities or commercial software, I need only the sql script.
thanks
Hi Forum,
I am currently implementing RDA Pulls and Pushes. Both worked fine for me, except when I try to pull a certain table twice. I read that in order to pull the table a second time I must drop it on the client.
My original approach was to use a select statement with a where criterium in the pull statement (e.g. SELECT * from tblPhonebook where Pulled = 0), then set Pulled to 1 and pull again later.
My understanding of RDA was that I use the where criterium to filter the data at the server side and simply append that data at the client side.
Can I simply append data in some way or do I really have to drop the table on the client side every time I pull?
Regards

Hi
I'm trying to Create a new Table from existing table in Q/Analyzer. I figured it would be something like this:
CREATE TABLE newTable AS(SELECT * FROM OldTable);
but i keep getting
Server: Msg 156, Level 15, State 1, Line 1Incorrect syntax near the keyword 'AS'.
also.. is there another method of doing this, something like
INSERT INTO newTable(SELECT * FROM OldTable);
and it creates the table ( newTable ) for u if it doenst already exist??
Cheers!!!

hi,
i have a table with data in the following format (dont ask why it was done this way, its not something i can change)
so my table looks like this:
point :timestamp :value
_________________________
var1 11:00 5
var2 11:00 2.3
var3 11:00 21
var1 12:00 5.2
var2 12:00 2.4
var3 12:00 18
and so on.
i would like to have my data rearranged to look like the following:
timestamp :var1 value :var2 value :var3 value
________________________________________________
11:00 x y z
12:00 a b c
....
i am working with my database in a c sharp application. so if anyone does come up with a solution for this maybe keep that in mind so that i can discuss how to impliment it in the code.
thanks guys.

View 2 Replies View RelatedI went to look at the connection string previously entered for a dataset created in a new report, and am not seeing anything intuitive for bringing up the associated datasource dialog box that was used to enter name, type and connection string. I'm also noticing nothing intuitive for deleting an existing dataset. How do you do these two very simple things in an existing project? I dont see the dataset in solution explorer, I see it only in the text box on the data tab and in a limited kind of way on the dataset view where the columns show and maint is allowed mostly on the columns only. I tried hilighting the dataset here and hitting the delete key to no avail.

I would like to restore database using RESTORE DATABASE ... REPLACE command.
If database exists already and has any open connections this command will fail.
I would like to close all existing connections to specific database before running RESTORE DATABASE ... REPLACE command.
I can do closing from Management Studio using checkbox "Close Existing Connection" when deleting database. Actually I need to do the same but from script.
Please advice me how to do it.
Thanks in advance,

I have a table for blog comments I want to add a column that counts the number of comments for each article.
existing table looks like this:
CommentID
ArticleID (FK)
commentAuthor
authorEmail
comment
commentDate (getDate())
I would like to add a column that counts the number of total comments for each article.This will give me what I want using the VS query tool:
"SELECT COUNT(comment) AS Expr1 FROM UserComments WHERE (articleid = @articleid)"
But can I add that to the table somehow so it does it automagically???
