'Equals' cannot compare a value of type <type1> with a value of type <type2>

  • Article

An Equals operator in a Join or Group Join clause has attempted to compare one data type to another in a way that is not defined. An example of this is a comparison of a Boolean value to a Date type.

Error ID: BC36621

To correct this error

  • Make sure that the values on each side of the Equals operator can be converted to a common data type. Some options for accomplishing this are:

    • Use the CType function to convert one or more of the values to a specific type.

    • Use the Convert class or conversion methods to convert one or more of the values to a common, immutable type.

    • Convert the values to strings by using the ToString method.
