Use an IDE for testing SQL statements
Include the table schema in SQL statements
It is a good practice to fully qualify your tables by including the schema of the table.
For example if you want to mirror an entire table:
SELECT * FROM <schema>.<table>;
Write comments in your SQL statements to document what they do.
Mitto only accepts multi-line comments due to job configurations being stored as JSON.
/* This is a comment. */ Select 1;
