                                                   int pageSize)

Query aggregation config info. The default sql: SELECT data_id,group_id,tenant_id,datum_id,app_name,content FROM config_info_aggr WHERE data_id=? AND group_id=? AND tenant_id=? ORDER BY datum_id LIMIT startRow,pageSize

参数:

startRow - The start index.

pageSize - The size of page.

返回:

The sql of querying aggregation config info.

findAllAggrGroupByDistinct
