THEN 'Q1' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('2', '3', '4') THEN 'Q2' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('5', '6', '7')
THEN 'Q3' ELSE CASE WHEN DATEPART(m, GETDATE()) IN ('8', '9', '10') THEN 'Q4' END END END END + '.dbo.all_data' EXECUTE sp_executesql @Query, N'@level tinyint', @level = 35
Can anybody please help on this.

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.

IF NOT EXISTS (SELECT TOP 1 1 FROM dbo.syscolumns WHERE id = OBJECT_ID(N'dbo.Employee) and name = 'DoNotCall')
BEGIN
ALTER TABLE [dbo].[Employee] ADD [DoNotCall] bit not null Constraint DoNot_Call_Default DEFAULT 0
IF ( @@ERROR <> 0 )
GOTO QuitWithRollback
END
It just takes a LOT of time in SQL Server Management studio. I have to cancel the query and cancelling takes a whole lot time. I am using SQL Server 2008.

Hi Everyone,
I have a simple webform with a text box with multiline enabled and a submit button, in vb.net. Inside the text box, when you are typing text with let's say adding carriage returns, spaces etc. How to i save the text to a database? By that, i mean, how to i declare the column in my database, varchar, text ...?
Also, when retrieving the saved text back to the textbox, will it keep the formatting because that's what i am trying to do? Or, what is the best way to keep text formatting in a database?
Thanks for the help,
Kevin

Hi,
I have a little bit of a problem I cannot seem to figure it out. Is it possible to write a Select statement that contains a WHERE column_name > desired_numeric_value
The tricky part it that the column is of CHAR type and can contain numeric grades ranging from 0-100 or the letter I for Incomplete.
My SQL was working perfect when this column contained only numbers as soon as a record with I was added I get the following error:
Character to numeric conversion error
This report will be used to find students who have failing grades. Thanks for any help!

I'm new to SQL server and am in the process of converting an Access Db to SQL.
What I'd like to happen is for the current date and an Autonumber generated as soon as the user enters a value in another field. This was fairly straightforward in Access. When I try to set the default in design table (inSQL), the date() is not available. After a little research I came up with CREATE DEFAULT and Bind column commands, Global variables, etc.
I have a couple of questions for anyone that might know:
Is there an easier way than this to create default values in a table? AND,
Would I also have to bind columns for Table lookups? For example, if I wanted a price to be returned after the product ID was entered (Automatic in Access if relationship/form setup properly), would I have to bind the column? Or would it happen automatically?

HiI have a table that currently has 466 columns and about 700,000records. Adding a new DEFAULT column to this table takes a long time.It it a lot faster to recreate the table with the new columns and thencopy all of the data across.As far as I am aware when you add a DEFAULT column the followinghappens:a) The column is added with a NULL propertyb) Each row is updated to be set to the DEFAULT valuec) The column is changed to NOT NULL.However, adding the column as NOT NULL with the DEFAULT seems to take alot longer than if I do steps a) - c) separately.When I say a long time, adding just a single DEFAULT column takesaround 6 hours. Surely it should not take this long?There is a trigger on this table but disabling this does not seem tomake much difference.Can anybody give me any advice on the use of DEFAULT columns please?When should they be used, benefits, disadvantages, alternatives etc.Also should it really take as long as it is taking or is there aproblem with my setup?If I am honest I can't see why DEFAULT columns should be used as thevalues could always be inserted explicitly via the applicationThanks in Advance.Paul

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

Hi guys/ladies I'm still having some trouble formatting a select statement correctly.
I am using a sqldatasource control on an aspx page. It is connecting via odbc string to an Informix database.
Here is my select statement cut down to the most basic elements.
SELECT commentFROM informix.ipr_stucomWHERE (comment > 70)
The column "comment" contains student grades ranging from 0-100 and the letters I, EE, P, F, etc. Therefore the column is of a char type. This is a problem because I cannot run the above statement without hitting an alpha record and getting the following error
"Character to numeric conversion error"
How can I write this statement where it will work in the datasource control and have it only look at numeric values and skip the alpha values?
I have tried case with cast and isnumeric... I don't think that I have the formating correct.
I have also used:
WHERE (NOT (comment = ' I' OR comment = ' EE' OR comment = ' NG' OR comment = ' WP' OR comment = ' WF' OR comment = ' P' OR comment = ' F'))
This works but is very clunky and could possibly break if other letters are input in the future. There has to be a better way.I am sorry for my ignorance and thanks again for your help.

I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.
The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?
Thanks.

Well here's one of those excruciatingly simple obstacles:
In SQL Server 2005 (Mgmt Studio): according to BOL, the syntax to set a default value for an existing column is:
ALTER TABLE MyCustomers ALTER COLUMN CompanyName SET DEFAULT 'A. Datum Corporation'
However, when I Check:
alter table CommissionPayment alter column Amount Set Default 0
I get the error message:
"Incorrect syntax near the keyword 'Set'."
No other combinations of this syntax work.
Help! What am I missing?

Hi,I have an application up and running. I need to add a new column to one of the tables which is currently being used - would adding a new column change or cause errors in the current application? e.g. if the table is being accessed by selecting * from table, will adding a new column cause an error? If there is any circumstance where an error would be caused by adding a new column, I will have to create an entirely new table. If I have to do this - how do I get a column in the new table to have the same values as a column in the old table? Can I create a computed column where column=oldcolumn? Thanks,Jon

I have a UDF that returns a char(10) random value. This runs fine when calling it directly via Query Analyzer, Stored Procs, etc.
I now want to create a new column in a table (via the Table Designer) and want to set the default value to the function. I have entered dbo.f_myfunction() for "Default Value", but I get an error:
Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Could not create constraint. See previous errors.
[Microsoft][ODBC SQL Server Driver][SQL Server]SqlDumpExceptionHandler: Process 51 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
The function is in the same database as the table. This is all on my local database where I am the admin.
I have also tried database.dbo.f_myfunction(), but I get an Invalid Object error.
Any help would be appreciated. Thank you,
JLM
