Convert a JSON object into an SQL where clause or into an LDAP filter.

JSON Query Object

AND, OR

Nesting of fields with AND and OR is possible with the keys #and and #or. This fields must take an object as a value. Nesting has no imposed limit on deepness.

Default operator and type

With no specific type and operator, it will default to equality operator and string type

{
    "#and": {
        "name": "John Doe",
        "city": "New York"
    }
}

Result :

• SQL -> name = "John Doe" AND city = "New York"
• LDAP -> (&(name=John Doe)(city=New York))

Sepcific type and operator

You can specify type and/or operator :

{
    "#and": {
        "name": {"operator": "~", "type": "str", "value": "Jo*"},
        "age": {"operator": ">=", "type": "int", "value": 21}
    }
}

Result:

• SQL -> name LIKE "Jo%" AND age >= 21
• LDAP -> (&(name=Jo*)(age>=21))

Nesting example

{
    "or": {
        "name": {"operator": "~", "value": "J*"},
        "#and": {
            "age": {"operator": "<", "type": "int", "value": 65},
            "age": {"operator": ">", "type": "int", "value": 18}
        }
    }
}

Result :

• SQL -> (name LIKE "J*" OR (age < 65 AND age > 18))
• LDAP -> (|(name=J*)(|(age<65)(age>18)))
