Glmaster table is used 7 times bcoz there are 7 differect type of GLCODES in supplierinvoiceheader table. and i want all 7 glcodes and its name in single query, because this view i used in JSP code.
the pk are as below of each table.
supplierinvoiceheader
UNIQUEID , DOCNUMBER
suppliermaster
UNIQUEID , SUPPLIERID
glmaster
GLCODE
jobtypemaster
JOBTYPEID
branchmaster
UNIQUEID
if you need another information then pl. let me know.
bye.
