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) ... )
     field ([idConteudo] [int] NULL)     to      ([idConteudo] [BigInt] NULL)
Or really should drop and create again?
CREATE TYPE [dbo].[tbProjeto] AS TABLE( [dsConteudo] [varchar](64) NOT NULL, [idConteudo] [int] NULL, [dtConteudo] [datetime] NULL DEFAULT (getdate()) ) GO
I'm trying to create a simple function that will do a count on a table. I want to pass the table name in form of a parameter to the variable and this function will return the count as an int. See my function below...
CREATE FUNCTION count_rows (@tablename varchar(100) RETURNS int AS BEGIN DECLARE @emp_count AS int declare @declaration varchar(100)
[Code] ....
The errors I am getting are as follows:
Msg 102, Level 15, State 1, Procedure count_rows, Line 3 Incorrect syntax near 'RETURNS'. Msg 102, Level 15, State 1, Procedure count_rows, Line 10 Incorrect syntax near '@declaration'. Msg 178, Level 15, State 1, Procedure count_rows, Line 14
A RETURN statement with a return value cannot be used in this context.
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.
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.

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?
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.
Hi 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?
I'm need to use typed Dataset with CLR UDT, but when I'm trying to create TableAdapter in Dataset designer, I'm gettng error message: User-defined data types are not supported in DataSet designer
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 3, Procedure spStoredproc, Line 0 Column or parameter #1: Cannot find data type udtcol1. 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.
Store Procedure creation text
CREATE PROCEDURE spStoredproc @col1 udtcol1, @col2 udtcol2, @col3 udtcol3 AS INSERT INTO tblTempEmployee (col1 , col2 , Col3) VALUES (@col1 , @col2, @col3) GO SET QUOTED_IDENTIFIER OFF SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER OFF SET ANSI_NULLS OFF GO
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?
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.
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
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.
Is there a way that I can create a user defined variable in my database? I have a fairly large chunk of xml that I would like to store in the database that can be updated by clients ( in rare cases ). I could use other mechinisms to allow access to it, but all other application related information is stored nicely in this one place, I hate to vary for this single piece.
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?
Please can anyone tell me if or how I have to cross reference to a user defined variable from a script task in the SQL of a Data Reader Source?
The script task creates a variable for the last Sales Ledger Session. The SQL in the data reader source that updates the DW sales invoice lines file based upon those invoice lines where the session number is greater than the value from the script task.
The SQL command in the custom properties doesn't cross reference back to the variable.
If anyone can help or needs further detail to help please post a resonse.
if a dataset doesnt use a stored proc to define a table variable, what is the scope of that table variable? Does the name need to be unique from such variables defined by other datasets?
I've been writing this stuff for a while, and can't seem to come to the conclusion of how I should be retrieving data and assigning this data to variables.
Since i'm using SQL Server, I'm convinced that I should be using the datareaders GetSqlDouble (or whatever) function, but this would mean i need my local variables to be one of the SQL types. The problem with that is, that there will have to be lots of conversions done by me to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order to retrieve them correctly (Null values included), I need to retrieve them with GetSqlDateTime(), then when it comes time to display the date in a table, i must first check for nulls, then convert to a string. This seems to be very cumbersome. Would I be better off just using GetDateTime(), and the .ToString method, and ignoring Sql Types all together?
so, basically, how are you guys using your sql server data? with the supplied sql types, and doing all of the post-processing work manually? I feel like i'm having trouble conveying my issue...hopefully someone knows what i mean....i'd just like some direction to save trouble in the long run, since i feel like there's got to be a better way...
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
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?
I'm trying to use a UDF that returns a table, but I'm not sure of the syntax to invoke it. I've found examples in BOL and on-line like the following:
SELECT * FROM dbo.fn_MyTableFunc( 123.09, 'MyID' )
But I need the input parameter to be obtained from another table. For a very simplistic example, I've got 4 tables (and yes, I know that I can get the results I want for this example without using a UDF, but humor me):
CREATE TABLE tUser (UserID int PRIMARY KEY, UserName varchar(50)) CREATE TABLE tAcctGroup (AcctGroupID int PRIMARY KEY, AcctGroupName varchar(50)) CREATE TABLE tAcct (AcctID int PRIMARY KEY, AcctGroupID int, AcctName varchar(50)) CREATE TABLE tMapUserToGroup (UserID int, AcctGroupID int) GO
INSERT INTO tUser VALUES (111, 'Me')
INSERT INTO tAcctGroup VALUES (1, 'NY') INSERT INTO tAcct VALUES (11, 1, 'New York City') INSERT INTO tAcct VALUES (12, 1, 'Syracuse')
INSERT INTO tAcctGroup VALUES (2, 'GA') INSERT INTO tAcct VALUES (21, 2, 'Atlanta') INSERT INTO tAcct VALUES (22, 2, 'Savannah') INSERT INTO tAcct VALUES (23, 2, 'Augusta')
INSERT INTO tAcctGroup VALUES (3, 'TX') INSERT INTO tAcct VALUES (31, 3, 'Dallas') INSERT INTO tAcct VALUES (32, 3, 'Houston') INSERT INTO tAcct VALUES (33, 3, 'El Paso') INSERT INTO tAcct VALUES (34, 3, 'San Antonio')
INSERT INTO tAcctGroup VALUES (4, 'CA') INSERT INTO tAcct VALUES (41, 4, 'Los Angeles') INSERT INTO tAcct VALUES (42, 4, 'San Francisco')
INSERT INTO tMapUserToGroup VALUES (111,2) INSERT INTO tMapUserToGroup VALUES (111,4) GO
CREATE FUNCTION dbo.ufnGetAcctList(@AcctGroupID int) RETURNS @tAcct table (AcctID int, AcctName varchar(50)) AS BEGIN INSERT INTO @tAcct SELECT AcctID, AcctName FROM tAcct WHERE AcctGroupID = @AcctGroupID RETURN END GO
I know that I can do: SELECT * FROM TestDB.dbo.ufnGetAcctList(4)
But I want the equivalent of: SELECT AcctID, AcctName FROM tAcct WHERE AcctGroupID IN (SELECT AcctGroupID FROM tMapUserToGroup WHERE UserID = 111)
Which uses tMapUserToGroup to obtain the AcctGroupID to pass into the function. The results would be: AcctID AcctName ----------------------------- 21 Atlanta 22 Savannah 23 Augusta 41 Los Angeles 42 San Francisco
Any thoughts? Thanks in advance for your help. Cat
CREATE TYPE dbo.MyTableType AS TABLE ( Name varchar(10) NOT NULL, ValueDate date NOT NULL, TenorSize smallint NOT NULL, TenorUnit char(1) NOT NULL, Rate float NOT NULL PRIMARY KEY (Name, ValueDate, TenorSize, TenorUnit) );
and I would like to create a table of this type. From this answer [URL] .... the suggestion was to try
CREATE TABLE dbo.MyNewTable AS dbo.MyTableType
which produced the following error message in my SQL Server Express 2012:
> Incorrect syntax near the keyword 'OF'.
Is this not supported by SQL Server Express? If so, could I create it some other way, for example using `DECLARE`?
