Produce one query per parent record

What does this MR do and why?

• To allow us to maximize parallelization of data transfer, produce one query per parent record with scripts/cells/generate-selects-for-organization.
• Add semicolon to end of all lines
• Remove unnecessary repetition of table name in all queries
