Bug Description

When I use a wrong SQL query on document data, I seem to delete the document data.

Reproduction Steps

• Add a document namespace
• Put document data in the namespace. I used this MQL code:

db.UserProperties.insert( { userid: "0", age: 20, eyecolor: "brown" } )
db.UserProperties.insert( { userid: "1", age: 40 } )

• Query the document namespace with a SQL expression that is wrong. I used this query:

SELECT * FROM gavel_doc."userid"

This throws an error:

Error:
From line 1, column 15 to line 1, column 32: Object 'userid' not found within 'gavel_doc'

But it also deletes the document data that was added with the MQL code above. At least, it isn't visible via the UI "Data" element anymore.

Expected Behavior

Throw the same error, but keep the data.

Hey @Anphisa, thank you for this issue.
Due to a missing commit on the catalog the implicit creation of the collection with the db.UserProperties.insert( { userid: "0", age: 20, eyecolor: "brown" } ) statement was still not fixed. This was then wrongfully also part of the rollback due to the incorrect query after.
This should be fixed in #437 but requires some testing as I have moved the commit of the catalog into the commit of the transaction itself.

To temporarily bypass this error from happening, the explicit creation of the collection can be used:
db.createCollection(("UserProperties")
This has to be executed between the creation of the namespace and the insertion.

Fixed in #438.
