Can some1 tell me the data types used in SQL Server for what like, i use Access so like i feel the data types are more intuitive, but for SQL Server in ASP, nchar, nvarchar, there are so many and i dunno what is what. any sites for beginners? cos i searched google and the terms they use to describe data types are like "variable length" "Unicode" i don't exactly know them. something like A-B, integers etc will be good.

I have a quick question about SQL Server 2000 supported datatypes!!
I have been trying to search on the "dreaded" Microsoft KB site to try and find information and details about the different supported data types on SQL Serv 2000, and to no avail!!!
Could anyone help me out and give me a rundown on the different data types that are supported on SQL Serv 2000, and maybe a quick explanation for each datatype, so I can make a better database?!??! I would really much appreciate any advice that anyone could offer...
Thanx in advance!!!

Hi Can anyone point me to a document somewhere that shows a mapping ofSQL Server 2000 datatypes to C datatypes? I am writing some extendedstored procedures which need to be able to process pretty much anydata type, so I want to make sure I am taking them from SRVPROC andstoring them in the correct C data type.Thanks,Bruce

View 6 Replies View RelatedIn Oracle when i create any procedure i define parameter datatype linked to under lying table.
For ex
create procedure testprocedure
(param1 customer.name%type,
param2 customer.salary%type )
Here i have defined param1 and param2 with datatype of name and salary of customer table respectively.
This way i do not need to worry about modifying param1 and param2 datatypes when datatypes of name & salary of customer table changes in future.
How can i accomplish this in SQL server.
I am designing my first SQL database and need some insight on datatypes.
What datatype is equivalent to autonumber like in MS Access.
When I convert an auto number field to to SQL it comes as int with a length of 4, Does this mean it will only auto increment to 9999?
I need the field to increment forever.
Also what datatypes should be used for phone number with area code and
zip code.
Thanks
Hi i'm using the FileSystemObject to loop through a file and read out all the data within it (it's an html page, so loads of tags and free text) and then put it in a field in a table. I am using the nText datatype but i don't think i use Full-Text Searching with this, is there any other i can use that produces the same result?
Cheers in advance...
Hello,
I'm 17 years old and I'm from Belgium, and I have to make a school project. I have to make a program in Visual Basic and my database is SQL Server 2000. I've already made my tables but I dont know excactly what all the datatypes in SQL Server are. They are a little bit different then Access datatypes and I dont know what to use, ntext, text, nvar, ... I can't find a list of the meaning of the datatypes on the net, maybe I'm searching with the wrong keywords(+"sql server" +datatypes in yahoo), but could please someone give me a link of a site where there is that kind of information?
thanks a lot :)

I'm new to SQLServer and I'm creating some tables. In Oracle I always used varchar as this was the default and also recommended. The default in SQLServer seems to be char. Am I right in thinking that varchar is still best to use, as the field can then be of variable length rather than fixed?

I have a SQL 2005 database that's created by a survey data collectionsystem. Users of this system are fairly non-technical and have littleto no conscious control over the datatypes. As a result, the data ismostly stored quite inefficiently as varchars. For example, there isdata that could be stored in a column of bits and it's stored as avarchar value of 0 or 1. (Yuck, I know.)I am building a reporting system using this raw data and have a newtable structure designed that is much more efficient (and better forreporting). Does anyone have any suggestions for getting this datainto my new structure? Specifically, how would you recommend checkingthat varchar field and determining it could be stored as a bit?

Two datatype problems: (1) Datetime conversion (2) Foreign Currency format.
The first problem is that I am trying to convert source data from varchar to datetime. The source data is in CSV format and is displayed as follows - '1111999052349' to represent 1-Nov-1999 05:23:49. Have converted to a numeric value and then tried to convert to datetime but this just returns the following message 'Server: Msg 8115, Level 16, State 2, Line 3
Arithmetic overflow error converting expression to data type datetime.' However you can convert to a timestamp but the value returned is not meaningful (e.g. 0x0E0000013DFA4EE8).
Problem 2 concerns the French currency. The source data is in CSV format and is displayed as follows - '00000001,9700' to represent Fr1.97. Need to convert this to a numeric field or alternatively get SQL 7 to recognise it as a money field.
Any suggestions would be musch appreciated.
Many Thanks.

Hi all. Im tryin to export (DTS) my some SQL server tables, many of which contain 'bit' datatypes. However, when DTS/SQL Serv. moves these bit datatypes out, it changes bit values to True/False values - which makes sense - however these are all going to plugin to web frontends where the SQL specifies condtions like: "if column1 = 0 then" etc..
Is there anyway to get SQL server to export bit datatypes as just numeric values of 0/1?
New to developing. We are working on a project using asp.net and c# where data is pulled out of an sql database via multiple tables and displayed via a details view. The user can then update the information and submit it back to the database.
The problem we are encountering is:
Within the database there are multiple tables joined by a FK for example there is a Service Group ID column with the Records main table linked to the Service Group table which holds an ID column and a Service Group column so ID1 = Service Group A. Any records within the main table which has an ID of 1, is shows as Service Group A in the details view.
What we wold like to do is when a user updates the Service Group via a drop down, the ID goes into the main table rather than the Service Group name so if they select Service Group B, an ID of 2 goes into the Records main table. We aren't sure how to go about doing the conversion of Service Group B to an ID 2? We have been looking at converting datatypes but don't think it is right for what we are trying to do,
Any suggestions would be gratefully recieved Apologies if this is in the wrong forum.
thanks

Dear Friends,
I have a problem with datatypes....
The error is "Cannot convert between unicode and non-unicode..."
The column in source is nvarchar(32) and in the destination is varchar(32)... ok...
But in the DataReader Source in the SQLCommand I've converted the column into varchar(32) with
convert(varchar(32), Equities.Equities_Name) as CL_FOLDER_ID
Do you have any tip??Thanks!

Hi All,
how do you convert from a date to an int ? as well as converting from Varchar to and Int
in SQL server 2000 ?
I am retrieving the GetDate() which i store in column as Varchar, i then want to use it within my select statement to calulate data which i want to return i.e
DECLARE @DateValue AS VARCHAR(20)
SELECT @DateValue = ApplicationSettingValue FROM ApplicationSettings WHERE ApplicationSettingKey = 'ProcessDate'
print convert(int,@DateValue) - 5
print GetDate() - 35
SELECT ccy_code, NULL, xrate_date, sterling_xrate
FROM SylvanTrans.dbo.SIADHP_XRate_Hist
WHERE xrate_date >= (CONVERT(int, @DateValue) - 35 )
ORDER BY xrate_date
now my as you can see in my WHERE CLAUSE i want to calculate what is returned using the GETDATE() stored in my @DateValue Variable, but the conversion throws a syntax error:
Server: Msg 245, Level 16, State 1, Line 3
Syntax error converting the varchar value 'GetDate()' to a column of data type int.
what am idoing wrong? i know it is something simple, unless there is no conversion from varchar to int?, i also tried setting the datatype for my variable as datetime but i got the same sort of error with DATETIME replacing the VARCHAR in the error!!!
thanks

I want to combine three fields together as a description in a select statement. When I try using the & or + I'm told that the datatypes are incompatable. How can I join them?
(Item_Description is Nvarchar, Item_Cost is Money, Is_Active is bit)
Select Item_Description &' '& Item_Cost &' '& Is_Active As Description FROM tblItemList I tried Casting this but same incompatable message.
Select Item_Description &' '& CAST(Item_Cost AS NVARCHAR) &' '& CAST(Is_Active AS NVARCHAR) As Description FROM tblItemList
What I'm hoping to end up with is:
Brake Pedal, $36.00, True
What is the difference between binary and image dataType.
When and how should I use them?
I would like to concatenate text datatypes. Is this possible??
I'm using field1 + " " + field2
I cannot convert to varchar since the size is larger than 8000.
Thanks, Vic

Can anyone explain to me how a column defined with a "bit null" datatype is physically stored in MSSQL? Is it stored like a "tinyint null" physically? In other words, how many bytes on the row on the page does a "bit null" datatype consume (assuming a non-null value 0, or 1 is the current value).
Is there any good documentation about the physical storage layout for a data page?
Thanks -
I have been inserting data From Access 2000 using the DTS import wizard. By default, I get the following datatypes
Access 2000 SQL Server 2000
datetime converts to smalldatetime
text converts to nvarchar
memo converts to nText
Is there a way to change the defaults? I would prefer to have varchar data in SQL server instead of nvarchar, and datetime instead of smalldatetime

Hi everybody!I'm working on a migration from Informix to SQL Server... I'm doing itthrough DTS and ODBC.What I'm doing is using the DTS, my data origin is tha Informixdatabase and mi target is the SQL Server database that I just created,this is via IBM Informix ODBC and I copy the tables... but the resultsare something like this:--INFORMIX--create table r_cap_dbt_uni(num_db smallint ,cve_uni char (8) ,fecha_mens datetime YEAR to MONTH ,valor float ,primary key ( num_db, cve_uni, fecha_mens ) ,foreign key ( num_db )references cat_db_tec ( num_db ));-- SQL SERVER --create table r_cap_dbt_uni(num_db smallint ,cve_uni char (8) ,***********************************************fecha_mens smalldatetime ,valor float ,***********************************************primary key ( num_db, cve_uni, fecha_mens ) ,foreign key ( num_db )references cat_db_tec ( num_db ));as you can see the float and datetime year to month data types changelike the example before.... I changed the "float" datatype manually to"decimal" datatype... but I don't know what to do with the "datetimeyear to month" Informix datatype, I mean, I dn't know why the DTSchanges this datatype to "smalldatetime"... how can I map this? what'sthe process?Thank you very much!Rodolfo
