How do I query a database conditionally？
|I need to ask how many conditions query the database
How to search for multiple conditions such as name='zhang san' and age<30 and city='shang hai'
#find（xxx,field） xxx Can only be the only condition？
In addition, some common commands about db help to list some.
Above is automatic translation, can answer in Chinese is also ok
very thanks !
