duplicate removal - How to SQL Query records from Multiple that Equal 0? -
i have table has multiple duplicate records in first column (id records), has varying numerical data in second column.
i want able identify id records have 0 of numerical records.
for example table can like:
id value 1 2 1 2 1 0 2 0 2 0 2 0
i want identify id 2 because values equal 0. don't want id 1 because there values > 0
sorry if isn't formatted or confusing.
select distinct id table id not in (select distinct id table value <> 0)
this take id in table there not row value non-zero.
