T-SQL (SS2K8) :: Check Constraint On Multiple Columns
Jul 25, 2014
I have a case where if the Id field is a specific value, I don't want to allow null in another field, but if the Id value <> a specific value, null is ok.
In the example below, inserting the first record should succeed, the second should succeed, and the 3rd should fail. Right now the 2nd two fail. I gotta be missing something easy, but I can't figure it out.
USE tempdb
GO
IF OBJECT_ID('tempdb.dbo.CheckConstraintTest') IS NOT NULL
DROP TABLE tempdb.dbo.CheckConstraintTest;
CREATE TABLE CheckConstraintTest
[Code] .....

I keep thinking this can be done in one query:UPDATE H
SET Phone1 = NULL
FROM Dialer.dbo.Agentless_Hold H
INNER JOIN Dialer.dbo.PhoneLookup D ON H.Phone1 = D.Phone;
UPDATE H
SET Phone2 = NULL
[Code] ....
I need to NULL any phone number in the Hold table where the number is in the Lookup table.

I'd like to first figure out the count of how many rows are not the Current Edition have the following:
Second I'd like to be able to select the primary key of all the rows involved
Third I'd like to select all the primary keys of just the rows not in the current edition
Not really sure how to describe this without making a dataset
CREATE TABLE [Project].[TestTable1](
[TestTable1_pk] [int] IDENTITY(1,1) NOT NULL,
[Source_ID] [int] NOT NULL,
[Edition_fk] [int] NOT NULL,
[Key1_fk] [int] NOT NULL,
[Key2_fk] [int] NOT NULL,
[Code] .....
Group by fails me because I only want the groups where the Edition_fk don't match...

I have two tables table1 and table2. I want to check a value from table1 against 4 different columns in table 2. What would be the most optimized way to do this. I came up with this SQL but it runs forever.
select * from table1 a
where
(a.id in (select orig_id from table2 where exctn_dt >= '01-OCT-14')) or
(a.acct_intrl_id in (select benef_id from table2 where exctn_dt >= '01-OCT-14')) or
(a.acct_intrl_id in (select send_id from table2 where exctn_dt >= '01-OCT-14')) or
(a.acct_intrl_id in (select rcv_id from table2 where exctn_dt >= '01-OCT-14'));

Can you update data from multiple tables in the same UPDATE statement, by joining those tables in a CTE ?
For example, this fails:
DECLARE @UPDCATE_COUNT AS int = 100000;
WITH COMBINED_TABLES AS (
SELECT TOP (@UPDATE_COUNT) T.UpdateID, T.IS_UPDATED, U.[Description]
FROM dbo.Table1 AS U
INNER JOIN dbo.Table2 AS T
[code]....

I'm in the process of trying to identify duplicate contacts. I doing this for millions of contacts and have gotten stuck and could use some elegant solutions!
The business rule is this:
Any contact that has the same name, phone and email address are the same contact
Any contact that has the same name, and email address are the same contact
Any contact that has the same name, email address, but different phone are a different contact.
Any contact that has the same name, email address, and a blank phone can be the same contact as one that has the same name, email address, and has an email address
Rank by the DataSource_fk. 1 being the highest
Put another way:
If 3 contacts have the same name, 2 have phone '1112223344' and all three have the email address 'johndoe@gmail.com' they are the same contact and the lowest DataSource_fk should be ranked the highest.
I've used the Row_number over (Partition by) in the past, but am unsure how to deal with the blanks in email and phone.
DROP TABLE [dbo].[TestBusinessContact];
GO
CREATE TABLE [dbo].[TestBusinessContact]
(
[TestBusinessContact_pk] INT IDENTITY(1,1)NOT NULL,
[Business_fk]INT NOT NULL CONSTRAINT DF_TestBusinessContact_Business_fk DEFAULT(0),
[Code] ......

I have multiple databases in the server and all my databases have tables: stdVersions, stdChangeLog. The stdVersions table have field called DatabaseVersion which stored the version of the database. The stdChangeLog table have a field called ChangedOn which stored the date of any change made in the database.
I need to write a query/stored procedure/function that will return all the database names, version and the date changed on. The results should look something like this:
DatabaseName DatabaseVersion DateChangedOn
OK5_AAGLASS 5.10.1.2 2015/01/12
OK5_SHOPRITE 5.9.1.6 2015/01/10
OK5_SALDANHA 5.10.1.2 2014/12/23
The results should be ordered by DateChangedOn.

I am trying to find a way to add into a table a flattened (comma seperated list) of email addresses based on the multiple columns of nformation in another table (joined by customer_full_name and postcode.
This is to highlight duplicate email addresses for people under the same customer_full_name and Postcode.
I have done this using a loop which loops through concatenating the email addresses but it takes 1minute to do 1000. The table is 19,000 so this isn't really acceptable. I have tried temp tables, table variables and none of this seems to make any difference. I think that it is becuase i am joining on text columns?
Create table #tempa
(
customer_Full_Name varchar(100),
Customer_Email varchar(100),
Postcode varchar(100),
AlternateEmail varchar(max)NULL
)
insert into #tempa (customer_full_name,customer_email,postcode)
[code]....

In SQL Server 2000, I want to apply a check constraint on a column type varchar that it is not duplicated. Could someone help me out with this?
Also, should I just make this column the primary key instead of an identity field being the primary key?
What is the performance difference by applying the constraint rather then just making it the primary key?

I have an existing table with field ZIPCODE defined as VARCHAR(5).
I want to add a check constraint to allow only number from 0 to 9.
This is what I did but it gave me error:
alter table test
with check
add constraint ck_test
check (zip between '0' and '9')
error:
ALTER TABLE statement conflicted with COLUMN CHECK constraint 'ck_test'.
The conflict occurred in database 'lahdProperty', table 'test', column 'Zip'.
What did I do wrong. Thanks for your help.

Hi, i want to put a check constraint on one of my tables to make sure that a member doesn't get loaded into the same usergroup twice. Could anyone please help me with this.
Here is some sample code:
Code Block
DECLARE @MyTable TABLE (ID INT IDENTITY(1,1), MemberID INT, ClientID INT, UsergroupID INT)
INSERT INTO @MyTable VALUES (123456, 211, 3054) -- Member gets loaded twice
INSERT INTO @MyTable VALUES (123456, 211, 3054)
INSERT INTO @MyTable VALUES (123456, 211, 3055) -- Same Member as the top but into ---- a different usergroup which is correct
INSERT INTO @MyTable VALUES (215489, 376, 2017)
INSERT INTO @MyTable VALUES (987512, 345, 2237)
INSERT INTO @MyTable VALUES (235479, 333, 1158)
INSERT INTO @MyTable VALUES (354985, 333, 1158)
SELECT * FROM @MyTable
The problem i have is that if a member is loaded into the same usergroup twice then the sites crash on the web applications and the member can't get into his profile page.Unfortunately i don't know which one of the 1000 stored procedures are used to access this table so that i could just change the query to SELECT TOP 1.
However i think that it will be better practive to just put a check contraint on the table and avoide the whole problem.
However 1 member can belong to multiple usergroups.
Any help will be greatly appreciated.
Kind Regards

In our database we have an indexed field that is using unique values, so in the index we turned on the unique property. Now with some changes we made in the application this value can be Null (could not be Null in the past). When we have more as 1 value having value Null we get an exception of unique key violation.
Therefor we want to make an check constraint the checks if the value allready exists when the value is not Null.
Is this possible and how can it be done?

Hi,
I am trying to enforce a rule that only one record in a table can have status 'Active'. I'd like to do this with CHECK constraint rather than trigger. I know SQL server doesn't support subqueries such as :
alter table add constraint chk_OnlyOneActive CHECK (1=(select count(*) from mytable where status='Active'))
Is there any workaround for this?
P.S. I tried using UDF like this:
alter table add constraint chk_OnlyOneActive CHECK (dbo.NumActiveRecords()=1)
and it works for insert - I am not able to insert a second "Active" record, but for some reason doesn't work for update - I am able to update existing record to status "Active" and end up with two or more Active records in the table.
Thank you.

I am creating a check constraint on a field (GRID_NBR) for values between 1 & 99. I am a little confused on creating the expression for it (Books online is vague).
Can I use the following expression: GRID_NBR BETWEEN 1 AND 99
Or do I have to use: GRID_NBR > 0 AND GRID_NBR < 100
Thanks!

Hi
I have a table with 3 columns in it. The ID column has a datetime data type.
Does anyone know how to apply a check constraint on this field so that the same month cannot be entered twice.
For example the field has the following data in the field
26/04/2008
27/05/2008
26/06/2008
25/07/2008
A user then tries to enter the value 20/05/2008, I would like the check constraint to block this value being entered due to the fact that a item with the same month value has already been entered.
Is this possible?
Thanking you in Advance!!!

Hi
I have created a table which contains date periods. It has 3 fields all with DateTime data types. These fields being ID, BeginDate, and EndDate. The ID field will hold a date indicating what month the reord is for, ie 01/03/2007 being March or 05/04/2007 being April. The BeginDate will contain the beginnig date for the financial month and EndDate for the financial month.
I am trying to apply a check constraint on the ID field so that combaination of a month and year can only be entered once, ie. if 01/03/2007 already exists in the table then 03/03/2007 cannot.
Is this possible?
Thanking you in advance!

I need to create a check constraint for an email column/field, where the field must contain an "@" symbol. Does sql (oracle or SQL in general) let you do this.
1. Tried myself:
ALTER TABLE Q_Customer
ADD CONSTRAINT Q_chk_Cus_email CHECK (Cus_email LIKE '%@%');
...but
ORA-02293: cannot validate (C3267304.Q_CHK_CUS_EMAIL) - check constraint violated
2. Tried from a forum: alter table Q_CUSTOMER
add constraint Q_Chk_cus_email check (Cus_email like '%_@__%.__%')
...but
ORA-02293: cannot validate (C3267304.Q_CHK_CUS_EMAIL) - check constraint violated

I want to incorporate a Check constraint within a trigger, based on this but im struggling with the coding.Assuming that is an Alphanumeric field you should be checking what value is in the alphanumeric column from inserted, comparing it with whatever is in the AMGR_User_Fields_Tbl to see if there’s a duplicate and then raising the error...This is my Trigger:
ALTER TRIGGER [dbo].[DUPLICATES]
ON [dbo].[AMGR_User_Fields_Tbl]
FOR INSERT, UPDATE
AS
DECLARE @Alphanumericcol VARCHAR (750)
-- This trigger has been created to check that duplicate rows are not inserted into table.
-- Check if row exists
SELECT @Alphanumericcol
FROM Inserted i, AMGR_User_Fields_Tbl t
[code]....

Hi there,
My problem should be fairly simple. Say i have a small table with 2 columns, employee_id and department_id. I want to create a check constraint so that no more than 4 employee_id can be associated with department_id and the user is warned if he/she is trying to do so. Can anyone advise me on how to do it?
Regards,
