Importing and Exporting in ASP.NET MVC Query builder control
22 Mar 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 Rule by importing a structured JSON object and defining its properties.

}Exporting
Exporting from the Query Builder allows users to preserve or store the created conditions. The defined conditions can be exported using various methods, including:
Exporting to JSON Object
You can extract the established conditions in the Query Builder and convert them into a structured JSON object format using the getRules method. This process enables users to save or transfer the conditions for further use or analysis in other applications or systems that support JSON data.
Exporting to SQL Query
Exporting to SQL involves converting the defined conditions within the Query Builder into SQL queries. This functionality allows users to generate SQL code representing the conditions set in the Query Builder, which can then be executed directly on a SQL database or used for further analysis and processing. SQL exporting supports various types, including Inline SQL, Parameter SQL, and Named Parameter SQL.
Exporting to Inline SQL Query
Exporting to Inline SQL Query entails embedding the defined conditions from the Query Builder directly into SQL statements within the exported code. This method ensures that the conditions are seamlessly integrated into the SQL query syntax, enabling straightforward execution or further processing within SQL database systems. This can be achieved using the getRulesFromSQL method.
