In U2000, two rows show the "unknown" ONT with different quantity of network element.
After running the script will fix this problem:
# isql -Usa -Psybase -SDBSVR
1>update BMSDB..bms_cpesvc_cpeinfo set EquipmentID = null where EquipmentID =''
1>update BMSDB..bms_cpesvc_cpeinfo set Version = null where Version =''
This bug can be fixed in V1R2C01SPC501 and later cersion, but for the existing data we only can modify it by script.
After checking the data in sybase, due to some value is not consistent (sometimes is null, but sometimes is empty) which is store in sybase, two different rows will show "unknown" network element. But actually they are the same.
