Using IPAddress Object In A User Defined Data Type
Sep 29, 2006
Im trying to use a .NET IPAddress in my UDT. i create the assembly, but i get this error when i try to create the type in SQL Server:
Type "IPAddress.IPAddressUDTType" is marked for native serialization, but field "address" of type "IPAddress.IPAddressUDTType" is not valid for native serialization.
From what i understand about the IPAddress object in .NET it is serializable. what am i doing wrong
( note, im just doing this for research purposes and not planing to use the UDT)

what are the advantages of using user-defined data types in SQL Server?
for example,
you may have Customer Number Cust_Num varchar(10)
you can create a user-defined data type like this:
udt_CustNum
so now your table creation script for Custome table become:
Cust_Num udt_CustNum
however, once the user-defined data type is referred by other tables.
it cannot be changed/deleted.
So, i wonder what are the good reason of using udt instead of fundamental data types. (built-in datatypes)
the only good thing i think is about:
the abstract naming of the data type.
you may have other key fields like Supplier Number which is varchar(12)
instead of u have to remember varchar(10) for customer and varchar(12) for supplier
u just to remember udt_CustNum for customer and udt_SuppNum for supplier.
what do u think?

Hi GuysWonder if you could help me.Basically I produce an accounts package that uses a SQL 2000 DB as theRDBMS. I always instruct users to login as 'sa' and the relevantpassword when doing an update to my program, as sometimes I need to dodatabase changes for new stuff.Found that one of my users has not only logged in with their loginname (in this case Edward), but have also made this login a 'db owner'so that when I created 2 new user-defined data types they belong toEdward rather than dbo.This must have happened a long time ago, but now that they want tomove Edward round the roles and/or delete him from a copy of thedatabase that they have, they can't because he's the owner of theseuser-defined types.This brings me to the reason for my post, how can I change the ownerfrom Edward to dbo for these data types? I found an article ontechnet of how to do this, but when it suggests changing myuser-defined type to standard format it doesn't seem to work.Any ideas?RgdsRobbie

Hi,
I created a user-defined datatype in Microsoft SQL server using the Enterprise Manager. But, I am not able to find options to edit this data type. There are options to delete but not for editing an existing user defined data type.
Can any one help me how to edit this user defined datatype ?
Also, are there any better ways to create and manage user defined data types in MS SQL ?
Thanks in advance ..

What is 'COLLATE SQL_Latin1_General_CP1_CI_AS'? I am new to
SQLServer, and couldn't find much information on the Web. Also,
I am trying to understand user defined data types. For example,
In the following example, what is '[Price_DT]' data type? and how would
it be referenced at the time of 'INSERT'.
CREATE TABLE [dbo].[Dist_Orders_Master_Index] (
[SubTotal] [Price_DT] NOT NULL ,
[Tax] [Price_DT] NOT NULL
) ON [PRIMARY]

I have several stored procedures with parameters that are defined withuser defined data types. The time it takes to run the procedures cantake 10 - 50 seconds depending on the procedure.If I change the parameter data types to the actual data type such asvarchar(10), etc., the stored procedure takes less that a second toreturn records. The user defined types are mostly varchar, but someothers such as int. They are all input type parameters.Any ideas on why the stored procedure would run much faster if notusing user defined types?Using SQL Server 2000.Thanks,DW

Hi,
After upgrading to MSSQL 2005 we have stored procedures which get this error:
Msg 2715, Level 16, State 7, Procedure prc_sel_accruals, Line 37
Column, parameter, or variable #15: Cannot find data type umoney.
The user data type is defined in the database. I tried recompiling the SP, which suucceeds but then fails on execution.
The SP works under SQL2000. Is there anything we need to do after the conversion?

Hi,
I am using VS2005 C# + sql server 2005 Express edition.
I need to using a database that uses my own defined data types to define its tables columns.
I already have designed a Database projact and create the new UDT as follows:
Create a new Database project in the Visual C# language nodes.
Add a reference to the SQL Server 2005 database that will contain the UDT.
Add a User-Defined Type class.
Write code to implement the UDT.
Select Deploy from the Build menu.
Now I need to ask some quistions:
1- When I try to add a new query to a table that contains my new data type in its columns,if I try to exexute the query the next message appears:
'Execution of user code in the .Net framework is disabled. Enable "clr enabled" configuration option'.
How can I doing that??
2- I need to use that database - which has the new data type - in a traditional ' Visual C# Windows Application' instead of 'Database', but:
when I try to add a new Data Source that contains the tables that have the new data types in its definitions, the next message appears:
'<AyaDatabase.dbo.MyNewUDTTable>
User-defined types(UDTs)are not supported in the Dataset Designer.'
So, how can I resolve that problem??
please help me.
Thanks in advance for any help.
Aya.

Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:
1/4/2006:1/10/2006
which would mean the time period from 1/4 to 1/10.

A common request for enhancement to applications is to "make thisfield bigger". I know I've been caught with increasing a field size,and then spending hours debugging because another stored proc has avariable or temp table that uses the field defined as the originalvarchar size. SQL Server just truncates to fit the data into thesmaller varchar, and so there are no errors raised.An option suggested by a colleague is to no longer use varchars, butuse User Defined Types instead. To make this work effectively,though, they suggest we would need to make it a rule that we do notuse varchars anywhere except to define user defined types.Though there will be one point of changes I can't help thinking thisisn't a very good idea ! Any thoughts ?Thanks.

I have created a store procedure in sql server 2005.
At first, it shows up as a normal user defined store procedure in Object explorer.
Recently, I found I could not found the procedure in normal place. But the execution is fine.
Finally I found it stays under system procedure folder.
How this could happen?

INSERT INTO @TESTTAB SELECT * FROM dbo.UTIL_TABLE_FROM_STRING(@szDelimit)
Note....The stored function returns a table.
Why doesn't this work ?:
SET @TESTTAB = (SELECT * FROM dbo.UTIL_TABLE_FROM_STRING(@szDelimit))
I wonder if I need to establish a user-defined table type ?I really just want a pointer to the table, and not to have to create a new copy.

I've got a user defined table type called StringDictionaryTVP:
CREATE TYPE [dbo].[StringDictionaryTVP] AS TABLE(
[key] [varchar](500) NULL,
[value] [varchar](500) NULL
)
Ideally I would like to be able to have a # of columns and directions in this table like so:
DECLARE @OrderByClause StringDictionaryTVP
INSERT INTO @OrderByClause([key], [value])
values('gender','desc')
INSERT INTO @OrderByClause([key], [value])
values('name','asc')
Since our database can be a bit sizable, I'd also like to use Common Table Expressions so I can page through them fairly easy.So my standard cte is something like this:
DECLARE @PageIndex INT = 0
DECLARE @PageSize INT = 20
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY name ) RowNum
from Users U)
SELECT * FROM results_cte
WHERE RowNum > @Offset AND RowNum <= @Offset + @PageSize
So where 'ORDER BY name' is I'd like to use the @OrderByClause in some sort of dynamic way. I've tried all kinds of stuff but even something like this doesn't get the actual column name I need
;WITH results_cte AS ( SELECT U.*, ROW_NUMBER() over ( ORDER BY (select top 1 [key] +' '+ [value] from @OrderByClause) ) RowNum
from Users U)
I may be chasing the wrong stick, but outside of dynamic sql, is something like this possible?

Is there a syntax to create indexes on user-defined type's fields and methods? Can I index UDT-fields?
I tried but only get syntax error.
Code Snippet
-- put an index on the picture luminance
CREATE INDEX myIdx ON myTbl(picMetaData.Brightness) -- !! error
GO
Error message:
Code Snippet
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '.'.
According to books online (BOL), section User-defined types requirements says
In the SQL Server 2005 RTM version, CLR UDTs with user-defined serialization were allowed to have their fields indexed as part of non-persisted computed columns or views. In such situations, non-deterministic UDT serialization/deserialization could lead to index corruption, and therefore has been removed from SQL Server 2005 SP1. In SQL Server 2005 SP1, UDT fields must use native serialization or be persisted in order to be indexed. Any existing indexes on UDT fields should continue to function as before.
What are BOL trying to say about index on UDT fields?
Thanks for any hints!

Hi all. We have a mix of informix and mssql server and I want to know if something we do in informix has an analogous feature in MSSQL. We can define a "row type" in informix, like so:
create row type name_1(fname char(20),lname char(20));
The when we create any table that includes a first and last name, we do so using this row type like so:
create table sometable(name name_1, some column,...etc)
This allows us to set a standard for certain common fields and avoids having different developers build the same type of field in more than one way, different lengths, etc.
Is there a similar function in MSSQL server?

Does anyone know where to find or how to write a quick user defined fucntionthat will return a table object when passed the string name of the tableobject. The reason why I want dynamicallly set the table name in a storedprocudue WITHOUT using concatination and exec a SQL String.HenceIf @small_int_parameter_previous = 1 then@vchar_tablename = "sales_previous"else@vchar_tablename = "sales"Endselect * from udf_TableLookup(@vchar_tablename )So if I pass 1, that means I want all records from "sales_previous"otherwise give me all records from "sales" (Sales_Previous would last yearssales data for example).udf_TableLookup would I guess lookup in sysobjects for the table name andreturn the table object? I don't know how to do this.I want to do this to avoid having 2 stored procedures..one for current andone for previous year.Please respond to group so others may benfiit from you knowledge.ThanksErik

Good Afternoon,
I have recently been tasked to come up with a means by which to create SQL data pulls based on user entries. What I mean by this is, I will have a pre defined SQL data pull set up and the user can then select the criteria upon which to pull said data.
So, say I want to display a table where one of the colums has is the "Year". I dont however want all years of data pulled, only 2005 - 2006. So, in form field 1, I could select start year as 2005 and in form field 2, I could select end year as 2006. This would then give me all data from this table based on that year range, or whatever year range I select and submit.
Is there a way to do this in ASP? I have been reading up on UDF with SQL, but I cant find anything about linking it through the use of web forms or through ASP. Or if there is another way to accomplish this? Any assistance is very much appreciated!
