query_master_each: Open one database and query data
In NREL/rplexos: Read and Analyze 'PLEXOS' Solutions

Used internally by query_master. Use that function instead to access data. The use of this function is not recommended

1 2	query_master_each(db, time, col, prop, columns = "name", time.range = NULL, filter = NULL, phase = 4)

`db`	PLEXOS database object
`time`	character. Table to query from (interval, day, week, month, year)
`col`	character. Collection to query
`prop`	character vector. Property or properties to query
`columns`	character. Data columns to query or aggregate by (defaults to `name`)
`time.range`	POSIXt or character. Range of dates of length 2 (given as date, datetime or character in 'ymdhms' or 'ymd' format). The Plexos data is assumed to be in UTC so providing a POSIXt vector in a different timezone might cause conflicts. Character vectors are also converted to the UTC format, so here there is not issue.
`filter`	list. Used to filter by data columns (see details)
`phase`	integer. PLEXOS optimization phase (1-LT, 2-PASA, 3-MT, 4-ST)
