I am trying to change a column from a decimal(18,2) to a decimal(18,3). What is the SQL command to alter this table?
SQL Command:
alter table TableName
alter column ColumnName decimal(18,3) [null]
the above command is right ?
Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
IF EXISTS (SELECT * FROM SYS.COLUMNS WHERE NAME =N'Case_Escalated__c' AND OBJECT_ID = OBJECT_ID(N'[Case]'))
begin
alter table [Case] alter column Case_Escalated__c bit null
print 'Case_Escalated__c altered sucessfully for [Case]'
end
Msg 1792, Level 16, State 1, Line 3
Alter table 'Case' failed because the added fixed column might cause existing data to go beyond the maximum allowable table row size of 8060 bytes.
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
View 1 Replies View RelatedI have existing table which is having Set Quoted Identifier Off and Set Ansi Null

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 have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon

Question: Why would I not be able to import an Access 97 table inwhich some records have null values in fields that allow null values?Wouldn't the table's design be imported first, bringing the columns'"allow nulls" attribute with it?I'm dealing with both text and numeric columns. Not all columnscontaining nulls cause an error.Thanks,Bob C.

Dear Members,
I extracted data from a flat file using SSIS package and load them into destination table. One column contains no data. Data type of that column is varchar(9). I want to display "NULL" values in that column.
I used LOOK up transformation and used the following query.
SELECT PassThroughRouting =

But it gives a error message.
Does any body can help me?

Hi,

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

I have two tables 1) tblCustomer (ID, Name, City) 2) tblemp (ID, NAME, Dept.ID, tblcustomer.ID)
Both the tables have ID as PKA emp can be either assigned a) All customers b)single customer c) NO customer
Pls note:- there will never be 2 or 3 customer linked to emp (my actuall requirement tables are different but to explain i am using the above tables)
I know how to assign single customer......but had problem how to link all customers and "no customer"
Please tell me if the following solution is right?1) I will manually insert a record in tblCustomer with id 0 as " all customers" and will not allow the user to delete it 2) store null in FK if it is "no customer"
Also please tell me is it ok to store one more value in tblCustomer as -1 and take it as "No customer"
I have a DDL in the Employee page which should be displaying the names of allthe customers with 2 extra values "ALL CUSTOMERS" and "SELECT" Select is the default value in DDL which says "NO CUSTOMER" selected yet

I have a table with data in two columns, item and system. I am trying to accomplish is we want to compare if an item exists in 1, 2 or all systems. If it exists, show item under that system's column, and display NULL in the other columns.
I have aSQL Fiddle that will allow you to visualize the schema.
The closest I've come to solving this is a SQL pivot, however, this is dependent on me knowing the name of the items, which I won't in a real life scenario.

SELECT distinct system, item FROM test

Hi,
I have a data transform from a flat-file to a SQL server database.
Some of the flat-file fields have NULL values. The SQL table I'm
importing into does not allow NULL values in any field, but each field
has a Default value specified.
I need to have it so that if a null value comes across in a field using
the data transform, it takes the table default on import. I could of
sworn I had this working a few days ago, but I get errors now that
state I'm violating table constraints. Has anyone done this before?
Thanks

Why can't I use:
Alter table myTable alter myCol int not null default(0)

Hello,
What is the Datatype for NULL ? How SQL Server stores NULL ? I have seen many discussions on this. Some say's that NULL will be considered as character type, then what about NULL value comes in a number column ?
Another article say's NULL is untyped. It don't have any type. Which one is correct ? Will there any difference for NULL in SQL Server and Oracle ?
Any help would be appreaciated
I have a table with a TEXT column that allows nulls.
Now I need to change it, and make it NOT NULL, but I Can't
ALTER TABLE BUSINESS_UNIT_LANG
alter column VISION text not null
And I get:
Server: Msg 4928, Level 16, State 1, Line 1
Cannot alter column 'VISION' because it is 'text'.
Is it impossible to make a text column NOT NULL when it accepts NULLS ?
All rows and columns are populated, in consequence there isn't any col with null values
Any idea?
Thanks!
I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

I'm using a table to hold data that I can pass back to the original form page and re-populate the fields that were not validated correctly. The stored procedure either inserts or updates the record in the temp table I've created.
So, currently, as I'm testing, I'm just passing empty values to all the parameters and the @state parameter is failing and throwing the error.
I've double checked that the table has the state column set to integer datatype
The column is set as follows:
Name datatype length Allow Nulls
----------------------------------------------
State int 4 checked
I have tried setting the default value for every column to Null in the table and then also not using a default value. Either way, I still recieve the same error?
Not sure what else to look at?
It seems the problem might be that instead of a null value being passed to the parameter that it is actually empty. Can passing an empty value to a column of datatype integer cause this problem? If so, is there a way to correct it?
Thanks for any help.
i have a little confusion...
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(CONVERT(DATE,@name),'')
Result: 1900-01-01
But..
DECLARE @name varchar(30)
SET @name = NULL
SELECT ISNULL(@name,'')
Does NULL inherit a datatype after convert?
