How do you alter a table to set a column which is currently int, to int not null?
I have already set all values to either 0 or 1.
Why can't I use:
Alter table myTable alter myCol int not null default(0)
I get a syntax error on the word default. If I remove "default(0)" then the command executes ok, but my Inserts don't work because there's no default value.
the Table columns is like this NO ProductNo Area In Out1 0001 US NULL NULL2 0002 UK NULL Y3 0003 FR Y NULL 4 0004 FR Y NULL5 0005 UK Y NULL I have Query get the result belowArea Count In&OutUS 1UK 2FR 2 the Area is Group By by Area and the Count columns is counting how many recoreds Table for each Areathe problem is the column "In & OUt'I have to make sure if the "In" or "Out" is Null , if one of them is Null the plus 1 so the result would like I have Query get the result belowArea Count In&OutUS 1 1 UK 2 1 FR 2 0 which syntax I can use for the problem? I just think maybe I can use IsNULL?but I have no idea how to wirte a query ...can you give me a hint? thank you
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;

I have a stored procedure that adds constraints from a variable: ALTER procedure [dbo].[addMyConst](@txtAuto_ourlim money OUTPUT,@txtGen_ourlim money OUTPUT)ASEXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_auto_ourlim DEFAULT ' + @txtAuto_ourlim + ' FOR Auto_ourlim')EXECUTE('ALTER TABLE [dbo].[tbl1] ADD CONSTRAINT DF_Gen_ourlim DEFAULT ' + @txtGen_ourlim + ' FOR Gen_ourlim') This works fine unless one of the variables is null or empty. Then I get the error: "Incorrect syntax near the keyword 'FOR' Evidendly SQL Server Express sees "....DEFAULT + + FOR..." but I don't know. I've fiddled with this a long time and haven't a clue how to fix it. Any help would be appreciated. Thanks, Steve
how can you alter a table so that you can add a default value whenever the field is NULL? for example, whenever the table is brought up in a query, NULL is replaced with UNKNOWN
Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'. ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO
I have existing table which is having Set Quoted Identifier Off and Set Ansi Null
Now I want to change those setting so Is there any alter statement for the same?
Also Let's say At my database level If those settings are off and If I convert it to ON then It is not taking effect on existing tables SP which are already build.
I ran this query against the pubs database and it runs successfully
ALTER TABLE publishers ALTER COLUMN state CHAR(25)
I change the table & field names for my db as follows: ALTER TABLE customquery ALTER COLUMN toclause CHAR(25)
and run against my database and I get the following error - Incorrect syntax near 'COLUMN'.
My column name is correct - I don't know why it would run fine against pubs, but not my db. I do not have quoted identifiers turned on. I have tried using [] around my column name [toclause], but that didn't change anything. Any help would be appreciated. Thanks.
I have a table with a column defined thus: LOCNumber Varchar(100) in atable called Bookdata.If I execute ALTER TABLE BookData ALTER COLUMN LOCNumber varchar(100)on the table, does any work get done on the table and column?Or does SqlServer know that the column is already varchar(100) andnothingneeds to be done?If it does do some work, how do you tell it not to run this as it isalready a varchar(100) column. Right now my program just blindly doesthis ALTER TABLEstatement regardless of any conditions. Is this a potential problem?Thanks for any help.
In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST SELECT '2014-09-30','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-29','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-28','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' GO INSERT INTO ##TEMP_TEST SELECT NULL,NULL,NULL,NULLÂ
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column.

I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

How can you rename a column in a table (from c# code, preferrably from a SQL script command) without deleting the column and re-creating it with a new name?
Hi I had a text type not null column which i wanted to change to a null column.Writing a simple alter statement gave me an eror cannot change text type column so i tried to rename the original column create a new column with the same name and allowing nulls on it and then copying the contents of the renamed column to the new column and finally deleting the renamed column. EXEC sp_rename 'TableName.ColumnName', 'ColumnName_old', 'COLUMN'ALTER TABLE TableName ADD ColumnName text NULLUPDATE TableName SET ColumnName = ColumnName_oldALTER TABLE TableName DROP COLUMN ColumnName_old However when i tried to execute these statements in query analyser on the Update statement it gave me the error that ColumnName_old does not exist. However then I tried to execute these queries one by one I was able to do that. Can anybody tell me whats causing the queries to not be executed all at once without giving the ColumnName_old does not exist error cause I wanted to run them on live dbs.
