Convert to partitioned table
Overview
This BLOCK copies data from multiple tables separated by date (date-sharded tables) into one partitioned table open_in_new
The date-sharded tables must have their names formatted as shown below:
tablename_YYYYMMDD
YYYY
: 4-digit year. E.g. 2016MM
: 2-digit month (01–12). E.g. 04DD
: 2-digit date (01–31). E.g. 09
For example, file names like sharded_20160401
and mytable_20161231
are properly formatted with the required year, month, and date in their suffixes.
