Martijn Bakker	f6987cfa52	have the parser recognize asof joins and feed them through to the executor ... insert the time series into a struct ready for joining working version that inserts the data into the hash table using the existing dispatching machinery for various types working asof left join in clickhouse add a test for the asof join do some asof join cleanup revisit the logic in case the values match between left and right side	2019-03-26 19:17:21 +00:00

Amos Bird	92811ca5f2	Make malformed array join statement fail early ... Currently array join clause that have no parent table can go through the parser and generates some confusing error. ``` create table aa (a Array(UInt64)) Engine=Memory; select * from array join aa; Received exception from server (version 1.1.54311): Code: 208. DB::Exception: Received from localhost:9000, ::1. DB::Exception: No columns in nested table aa. ``` This patch makes it fail at client side. ``` Syntax error: failed at position 21: select * from array join aa; Expected one of: SAMPLE, INNER, WITH, HAVING, SETTINGS, identifier, Dot, ORDER BY, AS, GROUP BY, INTO OUTFILE, UNION ALL, LEFT ARRAY JOIN, ARRAY JOIN, table, table function, subquery or list of joined tables, array join, alias, FINAL, PREWHERE, WHERE, token, FORMAT, LIMIT ``` However I'm not sure if `ParserCompoundIdentifier` should be stricter so that `array` wouldn't be consider as a table name.	2017-11-21 15:16:15 +08:00
