Question

大家好！我想在使用INNER JOIN后保存表格。

CREATE TABLE result AS (
SELECT  measures.Day,
SELECT  measures.Day,
    stations.Name,
    measures.name_measure,
    measures_of_stations.Count, 
    measures.unit
FROM
    measures_of_stations
    INNER JOIN
    stations
        ON measures_of_stations.id_station = stations.id_station
    INNER JOIN 
    measures
        ON measures_of_stations.id_measure = measures.id_measure)

但我有一个错误“旁边的语法无效（”。为什么？提前谢谢你：）

Answer 1

您需要使用INTO子句，请参阅下面的示例：

SELECT  measures.Day,
    stations.Name,
    measures.name_measure,
    measures_of_stations.Count, 
    measures.unit INTO result
FROM
    measures_of_stations
    INNER JOIN
    stations
        ON measures_of_stations.id_station = stations.id_station
    INNER JOIN 
    measures
        ON measures_of_stations.id_measure = measures.id_measure

Answer 2

SELECT  measures.Day,
    stations.Name,
    measures.name_measure,
    measures_of_stations.Count, 
    measures.unit
INTO result
FROM
    measures_of_stations
    INNER JOIN
    stations
        ON measures_of_stations.id_station = stations.id_station
    INNER JOIN 
    measures
        ON measures_of_stations.id_measure = measures.id_measure
