I've an Item table like;

Item Name        Price       Currency      CurrencySymbol
---------        -----       --------      --------------
ItemA             500          USD              $
ItemB             100          EURO             €
ItemC             150          USD              $

....

so what i need is , returning price data with correct currency formating.
Suppose i executed a query , it shall return dataset as ;

ItemName       TotalPrice
--------       ----------
ItemA             $ 500
ItemB             100 €
ItemC             $ 150

so how can i do it with SQL/TSQL ?

It's better not to do this as it will mangle your sorting.

Hi....

Check this Example...

SQL

DECLARE @Item TABLE (ItemName VARCHAR(30), Price NUMERIC(12,2), Currency VARCHAR(10), CurrencySymbol NVARCHAR(1))

INSERT INTO @Item (ItemName,Price,Currency,CurrencySymbol)
SELECT 'ItemA',500,'USD','$'
UNION ALL 
SELECT 'ItemB',100,'EURO','€'
UNION ALL
SELECT 'ItemC',150,'USD','$'

SELECT ItemName,CurrencySymbol + CAST(Price AS NVARCHAR) 'TotalPrice' FROM @Item

Don't do this in SQL, it's not the job of the database to format data. Instead, format the data in whatever medium you are presenting this information.

If you're presenting the information in a web app, you could apply the formatting at that stage.

It's the job of the presenter to format the data in the way it should be viewed, not the database

If you really insist on doing it in the database, some horrible mangled CASE statement would probably work :)

SQL

SELECT 
    ItemName, CASE WHEN Currency = 'EURO' THEN CONVERT(VARCHAR(10), Price) + CurrencySymbol ELSE CurrencySymbol + CONVERT(VARCHAR(10), Price) END AS FormattedPrice 
FROM
    ItemsTable

Reasonable. It could be done on the road to presenting the data. In the case DataGridView is used, OP can have a column which is not data bound and not used for sorting (see the comment to the question by Mehdi).

My current solution is formatting data at application side.I thought it would be better to fetch formatted data from database.I understand that now, it is a bad idea.
Thanks,
