User Defined Data Type Used In Stored Procedure Parameters
Jul 23, 2005
I have several stored procedures with parameters that are defined with
user defined data types. The time it takes to run the procedures can
take 10 - 50 seconds depending on the procedure.
If I change the parameter data types to the actual data type such as
varchar(10), etc., the stored procedure takes less that a second to
return records. The user defined types are mostly varchar, but some
others such as int. They are all input type parameters.
Any ideas on why the stored procedure would run much faster if not
using user defined types?
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.
I have defined a data type "OC_BUN_NAME" in database "CVPRO". I want to create a table tempdb.dbo.CVPRO in SQL SERVER 2005 system Database tempdb. But SQL SERVER 2005 DBMS gives a Error Messages:"Can not find the data type OC_BUN_NAME".
How can I do? How to use data types in the other database?
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
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)
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 ?
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]
Hello, I cannot find out to create enum data type in SQL Server 2005 Express. Can I easily create the enum type just like the MySQL does.(please the MySQL example below)
CREATE TABLE myTable ( myid INT UNSIGNED NOT NULL, myclass ENUM('FIRST','SECOND','THIRD') DEFAULT 'FIRST' PRIMARY KEY(myid) );
Hi,I'm tring to call a stored procedure i'v made from a DNN module, via .net control.When I try to execute this sql statement: EXEC my_proc_name 'prm_1', 'prm_2', ... the system displays this error: Could not find stored procedure ''. (including the trailings [".] chars :)I've tried to run the EXEC statement from SqlServerManagement Studio, and seems to works fine, but sometimes it displays the same error. So i've added the dbname and dbowner as prefix to my procedure name in the exec statement and then in SqlSrv ManStudio ALWAYS works, but in dnn it NEVER worked... Why? I think it could be a db permission problem but i'm not able to fix this trouble, since i'm not a db specialist and i don't know which contraint could give this problem. Also i've set to the ASPNET user the execute permissions for my procedure... nothing changes :( Shoud someone could help me? Note that I'm using a SqlDataSource object running the statement with the select() method (and by setting the appropriate SelectCommandType = SqlDataSourceCommandType.StoredProcedure ) and I'm using the 2005 sql server express Thank in advance,(/d
Does MS-SQL allow us to create an user-defined function within the stored-procedure script? I have been getting errors. It's my first time using the user-defined function with stored-procedure. I welcome your help.
Code:
CREATE FUNCTION ftnVehicleYearFormattor (@sValue VARCHAR(2)) RETURNS VARCHAR(2) AS BEGIN IF (LEN(@sValue) < 2) SET @sValue = '0' + @sValue
Hi.I'm really new to MSSQL, so therefore my question can sound stupid.Is it possible to use a function written in a module in MS-ACCESS in astored procedure?Or how can it be done, it is a complicated function with loop and more.I'll appreciate all answers also negatives ones.TIAJørn
I seem to be getting tasks that I am not familiar with these days. I am a guy that has coded it all in the asp page or in the code behind in .NET. This problem is outlined below and I need a help / advice on doing this. I had the flow of the 3 parts to it expanded below. A call is made to a Stored Procedure, The SP then calls a user defined function that runs SQL, this returns a 1 or 0 to the SP which then returns the value back to the call on the asp page. This is a lot I know but it is the way the lead guy wants it done. Any help so I can keep most of the hair I have left is appreciated :-)
Short list of process flow:
1. Form.asp calls to rx_sp_HasAccessToClient in SQL SERVER
2. rx_sp_HasAccessToClient then calls ab_HasAccessToClient
3. ab_HasAccessToClient runs SQL command on db and sends return bit back to rx_sp_HasAccessToClient
4. rx_sp_HasAccessToClient then sends this back to the call in the Form.asp page
5. Form.asp then checks the Boolean and if 1 then show or if 0 then deny.
<FLOW WITH CODE AND FUNCTIONS :>
This is not the correct syntax but is showing what I understand sort of how this is to be done so far.
This panel loads up the Vendors and id's when the user clicks on the link "view detailed list of vendors associated with this client". This is the beginning of the process.
This is code in Form.asp

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.
I have defined a user defined data type. When I try to create a stored procedure specifying the column and user define data tpye I receive message

Server: Msg 2715, Level 16, State 1, Procedure spStoredproc, Line 0 Column or parameter #2: Cannot find data type udtcol2. Server: Msg 2715, Level 16, State 1, Procedure spStoredproc, Line 0 Column or parameter #3: Cannot find data type udtcol3
Can you have user defined data types in stored procedures.

I built a database by using a generated script from the originaldatabase. It built the System Store Procedures as User type. How do Ichange them back to System type?
I have to write an aggregate which accumulates values in a relation to a parameter. Therefore I tried to create an aggregate with an additional input parameter.
While creating the aggregate, I get the following error message: CREATE AGGREGATE failed because type 'MKT' does not conform to UDAGG specification due to method 'Accumulate'.
Does anybody know, how I could solve this?
Public Sub Accumulate(ByVal value As SQLDouble, ByVal param1 as SQLDouble) Const uGK as double = 0.008
result = result + Math.Exp(-param1/(uGK *value) ) End Sub
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.
