[not-an-issue]No logs for a wrong 'CREATE INDEX' with expression

Hi ab,

When TSQLRestServerDB executes a wrong SQL like the following, it will failed without any errors being logged to the log file.

CREATE INDEX CustomerRelatedDocList ON Customer (
    JSON_EXTRACT(WrongFieldName, "$.RecordID") ASC,
    JSON_EXTRACT(WrongFieldName, "$.RecordClassName") 
);

For reference, the correct SQL is as following (and can be executed without issue):

CREATE INDEX CustomerRelatedDocList ON Customer (
    JSON_EXTRACT(RelatedDocList, "$.RecordID") ASC,
    JSON_EXTRACT(RelatedDocList, "$.RecordClassName") 
);

RelatedDocList is defined as a TObjectList which is persisted in JSON format.

I'm using this rev: https://github.com/synopse/mORMot/commi … 76b9b42046 (updated SQLite3 engine to latest version 3.22.0)

This is a Sqlite3 limitation, I'm afraid, not a framework problem...
