feat(query): query multiple symbols of different data format

[dakimura]

WHAT

• return multiple symbols data if common columns are specified on a query.

WHY

• some OHLCV symbols have columns other than Open/High/Low/Close/Volume, but sometimes we want to query just OHLCV columns for those different symbols in one query.
