[laysakura]

How to reproduce

        CREATE PUMP avg_by_ticker AS
        INSERT INTO sink_avg_by_ticker (ticker, avg_amount)
        SELECT STREAM
            source_trade.ticker,  -- here
            AVG(source_trade.amount) AS avg_amount
        FROM source_trade
        GROUP BY source_trade.ticker  -- and here
        FIXED WINDOW DURATION_SECS(10), DURATION_SECS(0);

Got

Workaround

Use alias

        CREATE PUMP avg_by_ticker AS
        INSERT INTO sink_avg_by_ticker (ticker, avg_amount)
        SELECT STREAM
            source_trade.ticker AS ticker,
            AVG(source_trade.amount) AS avg_amount
        FROM source_trade
        GROUP BY ticker
        FIXED WINDOW DURATION_SECS(10), DURATION_SECS(0);
