Well, you don't need the + signs before the @... in your SQL and the '' after @PRICENAME will cause you problems as well.

SQL

SELECT IM_SERIALNO,IM_ITEMCODE,''VALUE'' AS @PRICENAME ,IM_TAX FROM ITEM_MASTER WHERE
IM_COMPANYCODE  = @COMPANYCODE
    AND     IM_BRANCHCODE   =@BRANCHCODE

Try this:
SQL

SELECT IM_SERIALNO, IM_ITEMCODE, 'VALUE' AS @PRICENAME, IM_TAX FROM ITEM_MASTER WHERE IM_COMPANYCODE = @COMPANYCODE AND IM_BRANCHCODE =@BRANCHCODE

but i'm afraid about results...

'VALUE' AS @PRICENAME gives you:

@PRICENAME -column name<br />
VALUE -row <br />
VALUE -row <br />
VALUE<br />
VALUE<br />

Is it OK?

[EDIT]
The following 'query' shows how to use variables

SQL

DECLARE @PRICENAME VARCHAR(50)
DECLARE @COMPANYCODE VARCHAR(50)
DECLARE @BRANCHCODE VARCHAR(50)

SET @PRICENAME ='BlaBlaBla'
SET @COMPANYCODE ='UV2UV2UV2'
SET @BRANCHCODE ='q57438954rh8o9f'

SELECT  @PRICENAME AS 'PriceName' , @COMPANYCODE AS 'CompanyCode' , @BRANCHCODE AS 'SomeCode'

Result:

PriceName       CompanyCode     SomeCode<br />
BlaBlaBla	UV2UV2UV2	q57438954rh8o9f<br />

To select dynamic column, use:

SQL

IF @PRICENAME = 'SomeValue'
	BEGIN
		SELECT  [Columns1] ....
	END
ELSE
	BEGIN
		SELECT  [Column2] ...
	END

You can use a OBJECT_NAME[^] command to return the name of column too.
