Importing and Exporting in Blazor QueryBuilder Component

13 Sep 202424 minutes to read

Importing facilitates the viewing or editing of predefined conditions available in JSON, SQL, and MongoDB query formats, while exporting enables obtaining the created rules in the query builder as JSON, SQL, and MongoDB queries.

Importing

Importing enables users to bring predefined conditions into the system for viewing or editing, available in formats such as JSON, SQL, and MongoDB query. It facilitates the quick incorporation of pre-defined rules or parameters into workflows, streamlining the setup process by importing directly from external sources or saved configurations.

Importing from JSON Object

Importing from JSON enables users to bring predefined conditions encoded in JSON format into the system. This feature streamlines the process by providing a standardized format for importing data, ensuring compatibility, and ease of use.

Initial rendering

To initially apply conditions, you can establish the rules in QueryBuilderRule by importing a structured JSON object and defining its properties.

</SfQueryBuilder>

@code {
    SfQueryBuilder<EmployeeDetails> QueryBuilderObj;
    List<RuleModel> Rules = new List<RuleModel>()
    {
            new RuleModel { Field="Country", Label="Country", Type="String", Operator="equal", Value = "England" },
            new RuleModel { Field="EmployeeID", Label="EmployeeID",  Type="Number", Operator="notequal", Value = 1001 }
    };
    public List<EmployeeDetails> EmployeeData = new List<EmployeeDetails>
    {
        new EmployeeDetails{ FirstName = "Martin", EmployeeID = 1001, Country = "England", City = "Manchester", HireDate = new DateTime(2014, 4, 23) },
        new EmployeeDetails{ FirstName = "Benjamin", EmployeeID = 1002, Country = "England", City = "Birmingham", HireDate = new DateTime(2014, 6, 19) },
        new EmployeeDetails{ FirstName = "Stuart", EmployeeID = 1003, Country = "England", City = "London", HireDate = new DateTime(2014, 7, 4) },
        new EmployeeDetails{ FirstName = "Ben", EmployeeID = 1004, Country = "USA", City = "California", HireDate = new DateTime(2014, 8, 15) },
        new EmployeeDetails{ FirstName = "Joseph", EmployeeID = 1005, Country = "Spain", City = "Madrid", HireDate = new DateTime(2014, 8, 29) }
    };

    public class EmployeeDetails
    {
        public int EmployeeID { get; set; }
        public string FirstName { get; set; }
        public bool TitleOfCourtesy { get; set; }
        public string Title { get; set; }
        public DateTime HireDate { get; set; }
        public string Country { get; set; }

Exporting to MongoDB Query

Exporting to MongoDB Query involves converting the defined conditions within the Query Builder into MongoDB query syntax. This process allows users to generate MongoDB queries representing the conditions set in the Query Builder, which can then be executed directly on a MongoDB database or used for further analysis and processing. This can be accomplished using the GetMongoQuery method for exporting to MongoDB query.
