SQL Server 2008 Modified WHERE Statement -


my sql server 2008 table constructed follows: 160 columns consisting of ratio_id , 160 companies headers 742 rows consisting of ratio_id's per company.

the typical structure be:

ratio_id | company 1 | company 2 | company 160

part03x0 | 0.01 | 0.03 | ratio_id742 |

how able run query request companies ratio_id part03x0 zero?

tried google this, explaining difficult.

hope makes sense!

why storing companies columns? companies should placed in own table, unique id referring each company. can use id ratio_id in order perform query.

160 columns massive overkill. here nice tutorial on how normalize database.

edit:

you not need have table each company. need 1 table named, example, tbl_company , add following:

company_id  |  company_name       1       |   companynameone     2       |   companynametwo     3       |   companynamethree

another table ratios, tbl_ratio

 ratio_id   |   ratio_name      1       |    rationameone     2       |    rationametwo

then combine both using foreignkeys , relationships between 2 tables separate table below:

tbl_company_ratio

company_id   |   ratio_id    | ratio_amount     1               2              5    1               1              2    3               2              10    2               2              5   ....
