dgraph-dql

A “dgraph-dql” tool executes a pre-defined DQL statement against a Dgraph database.

About

A dgraph-dql tool executes a pre-defined DQL statement against a Dgraph database. It’s compatible with any of the following sources:

To run a statement as a query, you need to set the config isQuery=true. For upserts or mutations, set isQuery=false. You can also configure timeout for a query.

Note: This tool uses parameterized queries to prevent SQL injections. Query parameters can be used as substitutes for arbitrary expressions. Parameters cannot be used as substitutes for identifiers, column names, table names, or other parts of the query.

Example

tools:
  search_user:
    kind: dgraph-dql
    source: my-dgraph-source
    statement: |
      query all($role: string){
        users(func: has(name)) @filter(eq(role, $role) AND ge(age, 30) AND le(age, 50)) {
          uid
          name
          email
          role
          age
        }
      }
    isQuery: true
    timeout: 20s

     Use this tool to retrieve the details of users who are admins and are between 30 and 50 years old.
     The query returns the user's name, email, role, and age.
     This can be helpful when you want to fetch admin users within a specific age range.
     Example: Fetch admins aged between 30 and 50:
      [
        {
          "name": "Alice",
          "role": "admin",
          "age": 35
        },
        {
          "name": "Bob",
          "role": "admin",
          "age": 45
        }
      ]
    parameters:
      - name: $role
        type: string
        description: admin
tools:
  dgraph-manage-user-instance:
    kind: dgraph-dql
    source: my-dgraph-source
    isQuery: false
    statement: |
           {
            set {
            _:user1 <name> $user1 .
            _:user1 <email> $email1 .
            _:user1 <role> "admin" .
            _:user1 <age> "35" .

            _:user2 <name> $user2 .
            _:user2 <email> $email2 .
            _:user2 <role> "admin" .
            _:user2 <age> "45" .
            }
           }
