Update error message of mixing RDFGraph and regular Property graph table (hashtag2811)

[vikramsubramanian]

If I query this on a database with an RDFGraph and regular relationship tables I get the following error message:

..> match (a)-[e]->(b) return *;
Error: Binder exception: Relationship pattern e contains both property graph relationship label st_to_r and RDFGraph label TurtleTest. Mixing two tables in the same relationship pattern is not supported.

Let's change the error message to: ... Mixing relationships tables from an RDFGraph and regular relationship tables in one pattern is currently not supported. )

Summary: Error message for mixing RDFGraph and regular property graph tables needs to be updated.

Possible Solution

To address the issue described, you should update the error message in the code that throws the BinderException when a relationship pattern mixes RDFGraph and regular Property graph tables. Based on the provided snippets, the relevant code is likely in the file src/binder/bind/bind_graph_pattern.cpp.

• Locate the section of code in src/binder/bind/bind_graph_pattern.cpp that throws a BinderException when a relationship pattern contains mixed graph types.
• Replace the existing error message with the new error message: "Mixing relationships tables from an RDFGraph and regular relationship tables in one pattern is currently not supported."

The updated code snippet should look something like this:

if (!resourceTableIDs.empty()) {
    if (resourceTableIDs.size() > 1) {
        throw BinderException("Mixing relationships tables from an RDFGraph and regular relationship tables in one pattern is currently not supported.");
    }
    // ... rest of the code ...
}

Make sure to test the changes to confirm that the new error message is displayed when the exception is triggered.
