ICustomFunctionOperatorFormattable Interface

Defines server-side processing for Custom Functions.

Namespace:DevExpress.Data.Filtering
Assembly:DevExpress.Data.v19.1.dll

Expanded Syntax

Expanded Remarks

Implement this interface in addition to the ICustomFunctionOperator interface to provide a database-specific SQL command for your custom function. This interface declares the functionality required to evaluate the custom function within criteria on the database server.

If you want to make your custom function available to end-users in Expression Editors, implement the ICustomFunctionOperatorBrowsable interface as well.
