Query Builder tab

This tab enables you to build a filter query to:

  • View the data in a list that matches the selected criteria.

  • Interrogate and debug the data.

  • Search the data.

Query Builder

The Query Builder uses the following criteria to set up the filter.

  • Boolean logic to apply logical filter operations.
    • Select an appropriate operator from AND, OR, NOT.

  • Rules to apply comparative operators to return records with specified data values.
    • Select a data field, an operator, the value, and the data type in each line.
    • To add more rules, click the Add Rule or Add Group buttons.

  • Field tags to only display specified columns.
    • Click on Add a tag, then type in the column name.

  • Sort fields to list the data in a specific order using the Order By operator.
    • Click the + icon to add key index fields using the MongoDB Extended JSON specification.

  • Skip is used to omit the first n number of records as specified.
    • As an example, enter 5 into the input to omit the first five records.

  • Click the Query Values text button to execute the query and list the result below.
