I have the following fields in table A:

GL_ID|GL_Name_VC| Amount |Period_TI|Year_SI|
===================================================
1000| Sales_HW| -20,000.00 | 01 | 2005
===================================================
1000| Sales_SW| -10,000.00 | 01 | 2005
===================================================
1001| Cost_HW | 5,000.00 | 01 | 2005
===================================================
1001| Cost_SW | 5,000.00 | 01 | 2005

the fields above have the following datatype:

Fields | Datatype
===================================
GL_ID | Integer
GL_Name_VC | Variable Character
Amount | Integer
Period_TI | TinyInteger
Year_SI | SmallInteger

The above database is running on Microsoft SQL Server 2000 and i would like to query
for a report that looks something as below:

Sales Category | Sales | Cost | Profit
=================================================
HW |-20,000.00 |5,000.00| -15,000.00
SW |-10,000.00 |5,000.00| -5,000.00
=================================================
Total |-30,000.00 |10,000.00|-20,000.00


The above report have 4 columns, with last column being a calculated field (Sales-Cost)

Guys, hope someone out there can help me with the sql command for the above report?
