Why is there a limit of 8000 bytes on CLR Extension user defined types in SQl Server 2005?
We now have varchar(max), varbinary(max) and XML data types that are unlimited in size, byt UDT's are limited to 8000 bytes!.
This limitation is ruining a key project of mine!
Any ideas that MS may lift this limit?

I've been doing some reading on UDT's and have a question...
It was suggested in one of the pieces I read that you could create a UDT for, in their example, cities. And every table that had a reference to city could share this datatype. Now, my initial thought was "wow, what a great idea! I wouldn't have to remember the exact datatype for my primary keys (was it a char(5) or char(6)?) and have a "central depository" for my key datatypes.
So the first question is; what are the disadvantages of such a design?
And the second is; How do you update a UDT? If business requirements change and udt_city needs to be changed from varchar(30) to varchar(60), for example, what would be the way of echoing the change thoughout your database?
My gut reaction for the answers are
1) performance will decrease as effectively the dbms has to "parse" every insert/update to a UDT field in a different method.
2) create a new udt and alter any tables referencing the old one before dropping it.
What do we think?
Iam trying to create a geo-database.
For that i need to have a spatial data type called polygon which takes in values as int. so it can be declared as:
POLYGON(0 0, 100 0, 100 100, 0 100, 0 0)
How do i do that.
plz help.

Hi!
I have a question about creating a user defined type: I'd like to create a table of employee objects which include objects of the type employee_t. I used this structure before in Oracle 9i and would like to know how it can be done with MS SQL Server 2000 or 2005, preferably with Enteprise Manager/Management Studio. Below is an example.
CREATE TYPE employee_t AS OBJECT (
name VARCHAR(10)
jobDesc VARCHAR(15)
...
)
CREATE TABLE Employee of employee_t

I have a UserDefinedType that is Decimal(21,6)
The fields fltValorPendente e fltTotal are of this type. Field intSinal is an Integer.
I execute the following query:
SELECT
(intSinal * fltValorPendente) / fltTotal as Coef,
cast((intSinal * fltValorPendente) as decimal(21,6)) / fltTotal as CoefCast
into tmp
FROM tbl
Where fltTotal<>0
As a result, table tmp is created with the following structure:
CREATE TABLE [dbo].[tmp](
[Coef] [decimal](38, 6) NULL,
[CoefCast] [decimal](38, 17) NULL
) ON [PRIMARY]
How come both fields don't get the same precision?
I have a very simple SQL Server 2005 database, nothing fancy except that I use user-defined types (e.g., udt_Name = varchar(20)). I just set up a login for my first user, using Windows authentication, and gave her the following database access:
default schema = dbo
role = db_datareader
role = db_datawriter
Using SQL Server Management Studio, she can open any table; however, every column that is defined with a user-defined type appears with generic column headings (Expr1, Expr2 etc). And when she opens a table in design view, all columns with user-defined types have their Data Type field listed as "invalid type" rather than, say "udt_Name:varchar(20)". I browsed to the "User-defined Data Types" entry in Object Explorer, and it was empty.
In other words, it appears that she is unable to access the user-defined type aliases, even though she has read/write access to the database. As a very temporary work-around, I gave her membership in the database role "db_owner", but this is obviously not an ideal solution.
User-defined types are a great organizing tool and I don't want to have to redefine all my tables without them. What are my options?
Hi there
Can we have user defined data types in SSIS???

Is there a way to change the physical mapping of a user defined data type to the physical SQL Server datatype. It seems that once you create them, it is just about impossible to change it.
Thanks,

This is part of the codes of a stored procedure:
-- Create tables variables
DECLARE @_tab_PRNumList TABLE(
PRNum udt_PRNum
)
However, it cannot be compiled coz of this error:
Error 2715: Column or parameter #1: Cannot find data type udt_PRNum.
This user-defined data type is created in a user database only.
I tried to created the user-defined type into BOTH tempdb and master but same error.
How can i resolove it?
Or it is impossible to use user-defined datatype for table variable?
In the past,
i use this method:
CREATE TABLE #PRNumList (
PRNum udt_PRNum
)
and cerate udt_PRNum in tempdb only could solve it.
But now i want to use table variable.
It seems NOT work for my situation.
Any idea?
How can you tell which datatypes in a given database are user defined(with a query, not by looking in Enterprise Manager)? This is for SQLServer 2000.
View 2 Replies View RelatedHi all,I defined unsigned_int in my database, which uses unsigned_int_rangerule. The unsigned_int_range rule is defined as follows:@unsigned_int >=0 and @unsigned_int <=4294967295(4294967295 = 0xFFFFFFFF)The storage size is 4 bytes.One of the tables in the database contains a field that is of typeunsigned_int.When I try to add a new record into the table (ex: using the EnterpriseManager), it always fails in the unsigned_int field if I enter a valuegreater than 2147483647 (which is 0x7FFFFFFF) all the way to 4294967295(0xFFFFFFFF). The Enterprise Manager shows the following message:"The value you entered is not consistent with the data type orlength of the column, or over grid buffer limit."What is wrong here? The 4-byte storage should be good for any valuefrom 0 to 4294967295.Any help is appreciated.Thanks,Ken

I'm wondering, why CLR user-defined-types are case-sensitive in T-SQL?
When I create an udt with vb.net, e.g. udtPoint with properties X and Y and a method ToString(), I have to write udtPoint.X ..., udtPoint.x would raise an error. udtPoint.tostring() isn't working, too.
I like vb, because you don't have to remember whether syntax is upper or lower case. Same is with T-SQL, there's no difference between select * from table and Select * FROM Table. Intellisense would by great, but is not yet implemented .
I'd like to put this topic under suggestions (in my opinon it's a bug), what do you think about it?
Many thanks for your answers!

}
Working environment: Visual Studio 2005 SP1, MS SQL 2005 SP1 + Hotfix.
I have somw tables like Product, Sales, Customer.
I used UDTs like ProductCode = nvarchar(30)
CustomerCode= nvarchar(15)
How can I modify my UDTs ?Is there any quick way for that ?

Hello is there a way to change the owner of a user defined data type in sql2000? If so help is appreciated
View 1 Replies View RelatedHello,
Does anybody know an easy way to change User Defined Data Types ownership to “dbo”, without dropping dependent objects?
I know that there is a st. proc sp_changeobject owner, but it does not deal with this particular db objects. Is there a similar st.procedure or script that would do the same operation?
Thank you
We have a database that originally had all objects owned by a vendor id. We are in the process of changing the ownership to 'dbo' and wish to remove the vendor id but have found there are a few user defined datatypes that are also owned by this vendor id. How can I change the ownership of them to 'dbo'? They are currently being used in some of the tables. I tried the sp_changeobjectowner but that doesn't work for these.
thanks for any advice!
I have a table RequestUtility with 3 columns Vendor, name, system. I want to call this table from BizTalk so that I send multiple vendors and will get corresponding Vendor, name and system for that. As I need to send multiple vendors at the same time I have created a User-Defined Table type VendorNames with a single column Names. and have written a SP :
ALTER PROCEDURE [dbo].[GetName]
 -- Add the parameters for the stored procedure here
 @vendorN VendorNames ReadOnly
AS
 -- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
 SET NOCOUNT ON;
   -- Select statements for procedure here
 SELECT * from dbo.RequestUtility where Vendor IN (SELECT Names from @vendorN)
This is working fine when the value for vendor is present in the table. But if the value is not present it is not returning any thing. But, my requirement is that for example vendor is Dummy which is not present in the table so it should return
Vendor  Name System
Dummy NULL  NULL
But currently it is not returning anything.
I have a requirement of creating nested tables in SQL server. how to create them. Just to give a background I am trying to move the RDBMS from oracle to SQL server.
Structure of tables is as follows. I have table 'Employees' with address as one of the column. I have one more table with columns Street, Town, Dist, State. When I query the table 'Employees' I should see the attribute name and values of all the columns in address table in address column.
Employees: with columns: ID, FirstName, LastName, dept, gender, dob, address
Address (Nested table): with columns : Street, Town, Dist, State
This was done in oracle using Nested tables and user defined data types. what is alternative for this in SQL server. How can I achive this requirement in SQL server.

I'm trying to import some data from an Excel 2007 file into a SQL table. I created the Source Connection Manager and an OLE DB Source Data Flow Component which uses it. (Correct me if I'm wrong, but I can't use the Excel Source because of the version of Excel the file is saved in.) The outgoing Data Flow Path thinks some of the fields being imported should be of type float, when in fact they have alpha characters in them.
The fields in the database are defined as varchars.
A Data Conversion Transform doesn't seem right because I need the data to come out of the source as string data (which it actually is in the Excel file). Even if I convert it to string on the way to the destination, I would still be missing the original alpha characters.
How/Where do I change it (Source Connect Manager, OLE DB Source Data Flow Component, something else) to correctly identify the field's type?
TIA,
Christy
This question is around how we can get the data types and lengths populated into the flat file source columns.
In Connection Manager, you have your flat file defined. You can choose "Suggest Types...", and the minimum lengths and correct data types will be returned from within the data in the flat file.
Is there some way to automate this data type definition, but coming from the other direction (coming from the destination table that we are loading)?
For example, you have mapped the columns that will be loaded. Can you then reverse engineer the data types and lengths for the columns in the flat file from the destination table?
TIA

how can i identify the function is user defined or the system defined function....................
Our server has integrated security setup, upon startup of the server,

Does anyone know if a sprocs parameter has a size limit? For example if you're passing in a XML document to a sproc - could that call fail based upon the size of the XML document? Consider memory a non-issue.

Hi.
I have a service on a server which contains Sql Server Express.
this service adds documents to the database to allow full text search features.
From some reason, the index crashes and than it writes to the ErrorLog file, the errorlog jumps to 20GB(!) causing the server to crash.
How can :
1. limit the size of the error log.
2. find out why the log jumps to this size (I can't open the error log file ofcourse...)
Thanks!
