Description

Motivation

The SQL engine creates an implicit transaction if no transaction was passed from outside (QueryTransactionContextImpl#getOrStartImplicit). The started transaction does not have an implicit flag because Table Manager is responsible for this transaction type (commit or rollback). But the SQL engine has to manage an implicit transaction themselves (SQL script may have more than one table operation).

Definition of done

Transactions that were created by SQL engine also need to have the implicit flag.
