Datasets and varaible table name

joebaas10-Jul-07 3:27

Hi all!

I've a SQL (2005) database that is structured as follows:
- a schema called "salary"
- the table name is given by the year and the effective table name. Example 2007.employees
- that gives the table name salary.[2007.employees]

In my project I've created a typed dataset with the wizard. I've then renamed the table name in the dataset without the year (ex. 2007.employees -> employees).

In the application I can choose in which year to work and should load the data from the choosen year in the dataset. I should have the possibiltiy to pass to the tabeladapter the year I want. How can I do that?

Thanks for suggestions!

Jörg

I think you look in the properties of the data adapter and include parameters.

Yes it's possible the add parameters in the table adapter, but not for the table names. When you try to add a paramter for the table name, the query builder gives an error.

I'm now thinking to add a column "Year" in each table, so that each row is allocated in a year and all data is in one table and database.

Use the INNER JOIN syntax.

SELECT a.Col1, a.Col2 FROM TableA a 
INNER JOIN TableB b
ON b.FK_Field = a.PK_Field

This will return you rows where items are present in both tables only.

Use a left join:

select TableA.col1 ,TableA.col2 ,TableB.Col1<br />
From TableA<br />
inner join TableB on TableA.col3=TableB.Col9

Hi Chandu

Sounds like you need to "update". Something like:

update Table1 set StateName = Table2.StateName
  from Table2
  where Table2.StateCode = Table1.StateCode

Hi all,

I am new to SQL user defined function, I wrote an function on my own, I creates this function to get the count of total records available in an speciifed country, it works well, but where is no record in a specified country, it returs NULL and row count as 1. The function which i written is as below

CREATE FUNCTION [dbo].[cnt_country] (@country varchar(12))
RETURNS varchar(5) AS
BEGIN
declare @row_count varchar(5)
select @row_count=[country_code] from [dbo].[countrywise_users]
where [country_code]=@country
return @row_count
END

Actually i need to get the total row's available based on a country. If there is no records for an country , it should return null. Plz any one help me...

Did you mean: it should return 0?

In that case you can use:
return IsNull(@row_count, 0)
