SQL Server 2000 Table Data Types
Jul 20, 2005
Hi,
Can anybody tell me if it is possible to return a table data type (as
opposed to a temporary table) from a stored procedure.
I am currently studying for 70-229 using the Thomas Moore book but it
doesn't really make it clear, as the text suggests you can't return
them but some of his sample questions suggest you can.
I can't make it work in Query Analyser so I am assuming that you can't
return them. Is that correct?
Thanks in advance for any help,
Simon.

Hi,
Can anybody give me some information on Table data types of SQL2K.
How and where can it be used. Does it make the queries faster, in case there are many users using ?
Please could anybody give me these details, to make me decide whether I can use it or not ?
Thanx and Regards,
Sushma

I think I may have figured out the solution to my recent conundrum with SQL Server 2000 that had me stressed and depressed over the last couple of days. In a nutshell, after a HotFix was installed on a SQL2K database server I have space on, I was unable to perform INSERT or UPDATE queries on database table of type TEXT, when trying to either create or modify records with more than 4,000 characters of data. While it was frustrating as heck, it seemed too rigid to be random, so I did some snooping.
The HotFix was intended to solve a known problem of not being able to run UPDATEs against TEXT fields, but in so doing, caused another headache entirely: http://support.microsoft.com/?kbid=839523
Apparently this is a semi-known problem, in that a certain HotFix forces SQL Server 2000 to be a lot more stringent in requiring explicit declaration of data types and data lengths for parameters in stored procedure. In my client code, I was initially using the overloaded constructor of the SqlParameter object that took as arguments only the parameter name and a value, without specifying a value from the SQLDBType enumeration or length of the parameter (which in my case, needs to be TEXT and 16 (or 2147483647), respectively):
System.Data.SqlDataAdapter.InsertCommand.Parameters.Add(new SqlParameter("@parameterName",parameterValue);
It appears that after the HotFix is installed, if the client doesn’t syntactically set the type and length of data for a parameter, SQL Server and/or .NET will default to a type of NVARCHAR, which has the 4,000-character limit. This all makes sense. I’m going to now need to modify the code to straight out declare what’s going in the SPROC:
System.Data.SqlDataAdapter.InsertCommand.Parameters.Add(new SqlParameter("@parameterName",SqlDbType.Text);
System.Data.SqlDataAdapter.InsertCommand.Parameters["@parameterName"].Value = parameterValue;
It’s a minor change, and it sucks that I have to make it after the code had worked flawlessly over several thousands executions over several months, but c’est la vie! Better thay than have to rebuild my DB from scratch or switch to a new server. Changing the client code evidently is the only known fix at this time: http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b827366

I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.Â

I consider CURSOR and TABLE as data types but some one has argued that these are database objects.

Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
thanks.

I can find out the data types used in my table by navigating the SSMS and right clicking the table and selecting modify.
How do I view that same output using T-SQL?
Thank you

Our database stores vehicle data in one table, but 3 different types of data are stored in the one table. The table contains all the columns for all 3 types so when you query the table you get at least 3 rows back with null values for all the columns that don't apply to that record. The data is imported to the table when it's updates so there's a possibility that they're updated at different times so they have a different BATCH like:
BATCH TYPE ID RATING INSURANCE SAFETY
300 SAFE 123 NULL NULL A
300 INS 123 NULL YES NULL
250 RATE 123 A NULL NULL
What I'd like returned is:
ID, RATING, INSURANCE, SAFETY
123 A YES A
I'm trying to do a case statement to pull the data down, but I keep ending up with multiple rows because of all the nulls. I tried doing a SUM of the case statement with an ISNULL(SAFETY,0) but I can't SUM char values. I can probably do this with 3 temp tables to load the data that I want for each TYPE into them and then select and join them together, but is there a better way to do this?

Is it possible to easily copy data from one table to another if the data types don't match. I know you can do a INSERT INTO table1(col1,col2) SELECT (col2,col7) FROM table2 if the data types match but is there a way to do this if they don't. I'm not trying to copy date times into bit fields or anything. I just have an old table that I built when I really didn't know what I was doing now I at leastthink I have a better understanding of what data types to use, so I was wanting to move the data in the orignal table to my new one. Most of the fields in the olddatabase are text datatypes and the new database is nvarchar(50) data types. Thanks for any suggestions.

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

I am trying to produce a matrix (crosstab) report in SQL Server 2005 Reporting Services Report Designer, where the column headers contain a binary data type storing a png image.
By just simply using the report wizard and assigning the binary (image) data value to the column headers, and then previewing the report, I get following error:
An error occurred during local report processing.An error has occurred during report processing.The Group expression used in grouping 'matrix1_COMPETITOR_EMBLEM' returned a data type that is not valid.
Is there any way to include binary data types, or images per se from the database into a matrix or even table item in a report ?

I have a table with a datetime field 'TheDate'. Currently dates are stored as 'mm-dd-yyyy 00:00:00'. Is there a way to get just the month, day and year parts, '01/01/2008' into the field without changing the field data type to varchar? I'm asking because when I do this:
declare @MyDate as datetime
set @MyDate = '04/02/2008 18:00:00'
select substring(convert(varchar,@MyDate,101),1,10)
I get '04/02/2008', but when I do this:
update TheTable
set TheDate = substring(convert(varchar,TheDate,101),1,10)
I'm still getting a date in the format 'mm-dd-yyyy 00:00:00' stored in the table. I'd like to be able to lose the time portion, but I'd like to be able to keep the datetime datatype for date math purposes. Can it be done?

I am trying to create a clustered index on a View of a table that has an xml datatype. This indexing ran for two days and still did not complete. I tried to leave it running while continuing to use the database, but the SELECT statements where executing too slowly and the DML statements where Timing out. I there a way to control the server/cpu resources used by an indexing process. How can I determine the completion percentage or the indexing process. How can I make indexing the view with the xml data type take less time?
The table definition is displayed below.
CREATE TABLE [dbo].[AuditLogDetails](
[ID] [int] IDENTITY(1,1) NOT NULL,
[RecordID] [int] NOT NULL,
[TableName] [varchar](64) NOT NULL,
[Modifications] [xml] NOT NULL,

[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
The view definition is displayed below.
ALTER VIEW [dbo].[vwAuditLogDetails] WITH SCHEMABINDING
AS
SELECT P.ID,D.RecordID, dbo.f_GetModification(D.Modifications,P.ID) AS Modifications
FROM dbo.AuditLogParent P
INNER JOIN dbo.AuditLogDetails AS D ON dbo.f_GetIfModificationExist(D.Modifications,P.ID)=1
The definition for UDF f_GetModification
ALTER function [dbo].[f_GetModification]( @Modifications xml,@PID uniqueidentifier )
returns xml
with schemabinding
as
begin
declare @pidstr varchar(100)
SET @pidstr = LOWER(CONVERT(varchar(100), @PID))
return @Modifications.query('/Modifications/modification[@ID eq sql:variable("@pidstr")]')
end
The definition for UDF f_GetIfModificationExist
ALTER function [dbo].[f_GetIfModificationExist]( @Modifications xml,@PID uniqueidentifier )

end
The Statement to create the index is below.
CREATE UNIQUE CLUSTERED INDEX [IX_ID_RecordID] ON [dbo].[vwAuditLogDetails]

I am trying to write a generic stored procedure to return the data type of a given col in a given table in any database.
I would like to place this sp in master.
input parms are @TableName sysname and @ColName sysname
ouput parm is @data_type varchar(128)
set @data_type=''
select @data_type = data_type from information_schema.columns where table_name = @TableName and column_name = @ColName
when debugging this I always get 0 rows (@data_type remains '')
I have a thought that I can add an input parm for the database, say @DbName sysname
But I am having trouble updating the select stmt to be something like
...from @DbName +'.' + information_schema.columns.
Any Ideas?
Thanks for your help.

SQL Server 2000, ASP.Net 1.1
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...
Confused!
Thanks,
JJ

Is there a way to change the default data type in SQL Server? If I import a database into SQL Server it makes every non-numeric field a nvarchar field. Is there a way to change this so that these fields would be varchar or char by default? I cannot find any way to redo these as a batch/group update and have to modify every single field manually. Any insights greatly appreciated.

An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
Any inputs will be much appreciated.
Thanks,
MShah

I trust you'll bear with an SQL Server newbie with what may seem a rather inane request. I am designing a web app in Web Designer 2005 Express with SQL Server Express. Unfortunately, I'm finding a little confusing with some of the data types when designing tables. I have tried to find information on the various Microsoft sites (general site, MSDN, here) and while I found one document that had a table comparing data types in different implementations of SQL, it wasn't at all helpful. Most of my confusion is with the various string and char types; the numeric types seem pretty straight forward for the most part. However, it might be helpful to know the difference between money and smallmoney/datetime and smalldatetime, particularly space/size information and formatting options (unless the latter is up to the interface). It would also be helpful to know which string/char types correspond to any counterparts they might have in, for instance, Access (with which I am already quite exprienced). Or any particular quirks or idiosyncracies they might have. I don't expect anyone to write a full tutorial, but if someone could point me in the direction of a good online doc, it would be most appreciated. You might well ask, why not use Access databases? I would answer...I like to learn new stuff!
Thanks much.

We have a query that joins column A int which is an int onto column B with contains only int's but was created as a varchar and can't be changed to an int at the moment.
Casting column a as a varchar in the ON of the join to left join seems to void the index altogether and the query just runs for every.
We are talking a few hundred million rows of data in each table.
Temp solution is select into a #Hash table as correct data type and index then use the #Hash table in the join.

I have a simple Integration Services project and the problem is that decimal fields are importing as real (I'm loosing the digits behind the decimal point).
The project contains a data flow task importing a flat file (.csv) to an SQL Server destination. My .csv file has two decimal type fields. Example:
Field 1: 12345.67
Field 2: .123456
My database table that I'm importing to has two fields. The only way that I can get this data to import is to define the fields as "float" in both the text file and database table. I want the database table fields to be defined as decimal or numeric, not float:
Field 1: decimal(7,2)
Field 2: decimal(6,6)
When all fields are defined as decimal (in both the flat file and database file), I get the following results:
Field 1: 12345.00
Field 2: .000000
How does one import decimal data from a flat file (.csv)?
Thank you in advance!
