T-SQL (SS2K8) :: Cannot Define Primary Key Constraint On Nullable Column But Column Not Null
Sep 30, 2014We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change
DECLARE@size varchar(5)--The new size of the column
DECLARE @TSQL varchar(255)--Contains the code to be executed
DECLARE @Object varchar(50)--Holds the name of the table
DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10)
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1
Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.

How To Drop Primary Key By Specifying Column Only?
Apr 24, 2007I checked column from xsd file which created from DataBase.
And before installing my application I will check any column in destination base whether have complete column or not.
And if there is any column which is not wanted column(not same as xsd structure)
I will delete it by creating sql command as follow "ALTER TABLE tableName DROP COLUMN column1, column2, ......"
and Execute it by program initialization.
So
I need delete it by run-time
However some column may be Primary Key with any reason
That's why I can't delete them by simple command
I expect to delete them by specific column instead of specific constraint name which is not sure name.
Please advise me....

View 1 Replies View RelatedDesignating An Identity Column When You Already Have Primary Key
Jan 13, 2007Hello --
Following normal practice, I have an autoincrementing identity column designated as primary key in my table. I have two other columns that should also contain unique values per record, but the Identity option is greyed out (in Management Studio) for all columns other than the primary key.
I'm enforcing this programmatically (in my C# code) at this point, but I'd like to back that up with a constraint in the database itself.
Any help is appreciated.

Getting Primary Key Column Names For All Tables
Sep 9, 1999I have a situation in which i have to get the last value stored in the Primary Key for all the tables. Based on this value i have to update another table which stores the Table names and the last Key value for the table. The values in this table are not correct therefore i have to update it now. I was trying to write a cursor for this but the only problem is i can't get to know how to get the column name on which the primary key is defined for all the tables, thru code.
I would appreciate if someone could help me out with this.
Problems With Computing A Primary Key Column
Sep 13, 2006hi !
Just started playing around with SQL 2000 and I createda sample table called 'actor' which has 4 columns
1. actorID
(formula= LEFT(NEWID(), 3)+ LEFT([actorFirst], 2) +
LEFT([actorLast], 2) + RIGHT(NEWID(), 3))
2. actorFirst
varchar(20) NOT NULL
3. actorLast
varchar(20) NOT NULL
4. actorName
(formula = [actorFirst] + ' ' + [actorLast]
Now my problem is that I want to set a primary key constraint on actorID but it doesn't let me because it the NULL check mark is automatically checked and I cannot check it off ... and I can't set a primary key on something which is allowed to be NULL....
I don't understand why 'actorName' column which is also calculated doesn't have that default NULL checked and locked ....
What am I doing wrong ? Please help ....
Creating Primary Key On Nullable Column
Feb 29, 2008Hello,
I am trying to recreate a primary key that I dropped in a table....
I'm using a statement like
ALTER TABLE temp WITH NOCHECK add CONSTRAINT PK__tempkey PRIMARY KEY CLUSTERED
(
num,
store
)
But apparently the "store" column was created without a "not null" and it let it create the PK during the table creation but now it won't let me add the PK with that nullable column..
Does anyone know how to get it to use that column to create a primary key after the initial table creation?
Here is the error i get
Cannot define PRIMARY KEY constraint on nullable column in table
