I have two fields CourseID and Erpid in table.
CourseID has identity property with integer datatype.
I need to add a default value for Erpid column which will show a value like 'A' + CourseID column. Erpid is Varchar column.
How can I use Convert function in default constraint?
Thanks!
In the code below I want the table to refuse inserts that are duplicate IDs, Users, Addresses and Days. InsertDateTime is a date which has precision to the second. I know I cannot use a primary key without creating another column that converts InsertDateTime to day precision.
With the code below I get an error. Can convert not be used in a constraint? And if so, is there another way that I can do what I'm trying to do without creating a seperate column?
ALTER TABLE exampletable
ADD CONSTRAINT unique_submit
UNIQUE (ID, User, Address, convert(varchar(),InsertDateTime,112))
Hi,I see the following in Books Online: CONSTRAINT--Is an optional keywordindicating the beginning of a PRIMARY KEY, NOT NULL, UNIQUE, FOREIGNKEY, or CHECK constraint definition...But I have a table column defined as follows:[MONTH] [decimal] (2, 0) NOT NULL CONSTRAINT[DF__TBLNAME__MONTH__216361A7] DEFAULT (0)My question: Is "DEFAULT" a constraint, or is it called something else?Thanks,Eric

A few weeks ago a client asked me to add a column to a table so Icreated this script:ALTER TABLE dbo.tblIndividual ADD fldRenewalStatus BIT NOT NULLCONSTRAINT fldRenewalStatus_Default DEFAULT 0Now they want to change it from a BIT to an INT, to store an enum.Fair enough. However, no matter how much I wrangle with a script, Ican't find a reliable way to alter the column. I've mixed and matchedthe following and nothing seems to work:EXEC sp_unbindefault 'tblIndividual.fldRenewalStatus'DROP DEFAULT DF_tblIndividual_fldRenewalStatusALTER TABLE tblIndividualDROP CONSTRAINT fldRenewalStatus_DefaultALTER TABLE tblIndividualDROP COLUMN fldRenewalStatusGOALTER TABLE tblIndividualADD fldRenewalStatus int NOT NULLCONSTRAINT fldRenewalStatus_Default DEFAULT 0Thoughts?ThanksEdward

I have a table set up called tbl_DailySummary_new. In that table I have a column called €˜RevType€™ char(2) NOT NULL Default €˜00€™. I'm trying to populate this table from another table called tbl_DailySummary. The RevType column in tbl_DailySummary allows null values (and has them). When I attempt to insert all records from tbl_dailysummary into tbl_DailySummary_new, I get the following error message:
Msg 515, Level 16, State 2, Line 1
Cannot insert the value NULL into column 'RevType', table 'TxnRptg.dbo.tbl_DailySummary_new'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Why dosen€™t the default constraint on the RevType column in the new table pick this up?
Thank you for your help!

Troops,
I'm a software developer trying to hack my way thru a SQL script to increase the size of a column. The column has a constraint on it that won't allow the alter unless its dropped.
Alter command:
ALTER TABLE dbo.QueueBack ALTER Column QBQueue varchar(4) NOT NULL
Message response:
Msg 5074, Level 16, State 1, Line 10
The object 'DF__QueueBack__QBQue__76818E95' is dependent on column 'QBQueue'.
Msg 4922, Level 16, State 9, Line 10
ALTER TABLE ALTER COLUMN QBQueue failed because one or more objects access this column.
So, my script drops the default constraint, alters the column size and then adds the constraint back. The problem is that the constraint does NOT appear to be the same as it was prior. I can run the Alter command on the column and it will allow me to change the size of the column... where it prohibited me from doing such before. How do I restore the default constraint so it is exactly the way it was before I dropped it?
Thx,
Stretch

Okay, maybe I'm getting ahead of myself.
Using SQL Server Express, VWD and .net 2.0 I've figured out how to drop a Table Column Constraint or Default Value/Binding and then Create it again using a stored procedure. What I can't figure out is how to retrieve that column's constraint value and write it to, say a label, in an aspx page, simply for reference. Is it possible? In this case the Data Type of the column is money.
I'm using it to perform a calculation to a column with a value that the user inserts into another column. (Column1(user input) minus Column2(with Default Value) = Column3(Difference). I just want to read Column2's Default Value for reference so I know whether to change it or not.
I can't seem to get the syntax correct for ALTERing an existing column with a default constraint. I've been to Help and BOL. There are examples that show how to use the ALTER command to add a column with a default constraint but not how to do it on an existing column.
Any help would be appreciated.

Hi guys,
I have this problem. I want to add a new primary key to a table but i want the name of the contstraint to be generated by the system. I have this TSQL code.
ALTER TABLE TableTest
ADD CONSTRAINT PRIMARY KEY (C1)
Reading the BOL, it says that if you don't supply a name for the constraint it generates one. But I get this error "Incorrect syntax near the keyword 'PRIMARY'".
If I add a name to the constraint, it works fine.
I'm using SQL Server 2000
Thanks

I have a default constratint on DateColumn getdate()-1
I have used enterprise manager to update it to yesterday's date everyday.
I would like to have a SQL which can check for the date in the system
or even a trigger which checks when the date changes the constraint is updated itself. If this is not possible I would like to have a stored procedure which I will schedule to run as a job everyday once.
So if today 6/12/2006, the default value in the Datecolumn should be
6/11/2006.
This gives me a error, i tried but could not fix the bug.
Alter Table TABLE_NAME
Alter Constraint DF_DATECOLUMN

I cannot figure out how to add a default constraint to an existing column. The syntax I'm using is :
ALTER TABLE table_name WITH NOCHECK
ADD CONSTRAINT column_name DEFAULT (0)
This gives me a syntax error.
The column was originally added with a default constraint of 1 to a 2.6 million row table.
I dropped the existing constraint and need to add the new default constraint of 0 for that column.
Anyone have any ideas? Thanks in advance.
I need to alter the datatype of a column from smallint to decimal (14,2) but the column was originally created with the following:
alter my_table
add col_1 smallintNot Null
constraint df_my_table__col_1 default 0
go
I want to keep the default constraint, but i get errors when I try to do the following to alter the datatype:
alter table my_table
alter column col_1 decimal(14,2)Not Null
go
Do I need to drop the constraint before I alter the column and then rebuild the constraint? An example would be helpful.
Thx
What are the tables are having the Default Constraint those table's Script the User can't generate but remaining tables He/She can generate,If i want DENY he/she to do not generate the script those are not having the DF Constraints what should i do.....

Are there any vices to using default constraints on all columns in your table.
For example an Int that defaults to 0
or a char or varchar that defaults to ''
I know that 0 and Null are not the same thing. But if your programs don't have the concept of NULL then you have to convert the NULL to zero.
So, DEFAULT CONSTRAINTS on every column. Is it good or Bad?
Thanks

I have this function in access I need to be able to use in ms sql. Having problems trying to get it to work. The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String Dim strReturn As String If IsNull(strField) = True Then strReturn = "" Else strReturn = strField Do While Left(strReturn, 1) = "0" strReturn = Mid(strReturn, 2) Loop End If TrimZero = strReturnEnd Function

I've a Problem with a Function called by different users.
I want the different callers to query a table in their own default Schema.
So if i refence the full Path [Schema].[Tablename] it works Properly.
If i just Use the [Tablename] for reference it fails.
The function was created with EXECUTE AS CALLER option ;
if I call it with dynamic SQL i retreive the error-message

does anybody know a solution for this problem?

Hi, I have found some ways on using Convert() function for SQL server. But i do not understand some of them.
Example:
CONVERT(VARCHAR(10),column name,108)
What is the 108 for? I see some with 120 and 101. I tried all but only 108 is working for me the way I want..but i do not understand what is that for actually. Can anyone explain it to me? Thank you.

Hi all,
I have found an interesting problem with Convert function. When you Use this function to Convert Datetime to varchar and if the date happens to be 01/01/2000 or higher it return nothing. here is an Example.
CREATE TABLE ABC (Id int, Datein Datetime NOT NULL Default getdate())
GO
INSERT INTO ABC VALUES(1,'12/31/1999')
INSERT INTO ABC VALUES(2,'12/31/1999')
INSERT INTO ABC VALUES(3,'12/31/1999')
GO
SELECT *
FROM ABC
WHERE CONVERT(varchar,DateIn,101) < '01/01/2000'
-- This query returns Nothing
SELECT *
FROM ABC
WHERE DateIn < '01/01/2000 00:00:00'
AND DateIn > '12/30/1999 23:59:59'
-- this Query return the 3 row that it is suppose to.
Is there a Fix for this problem that any one know of.
