Oracle SQLcl Tips
Table DDL (and a lot of other DDL for that matter) can be generated using DBMS_METADATA. This package has been part of the Oracle database for a long time now and it is documented in the PL/SQL Packages and Types Guide.
DBMS_METADTA is very useful, but it requires a bit of code. And now SQLcl provides a shortcut to using the DBMS_METADATA invoking the PL/SQL API.

Oracle SQLT Tips
SQLTXPLAIN, also known as SQLT, is a tool provided by Oracle Server Technologies Center of Expertise - ST CoE. SQLT inputs one SQL statement and outputs a set of diagnostics files. These files are commonly used to diagnose SQL statements performing poorly. SQLT connects to the database and collects execution plans, Cost-based Optimizer CBO statistics, schema objects metadata, performance statistics, configuration parameters, and similar elements that influence the performance of the SQL being analyzed.
Licensing (SQLT requires no license and is FREE)
Execution plans, execution statistics, data volume, etc. Those have to be taken for the same query(ies) from different env.
SQLT helps gathering these info.
