Initial value:

=
    "Column type and value type are not compatible. "
    "Column types must match the value types being compared. "
    "For string columns, you can use std::string, std::string_view, or const char*. "
    "For optional columns, you can compare with the underlying type or another optional. "
    "For numeric columns, types must match exactly (use explicit casts if needed)."

Constant error message for type mismatches.
