使用where子句时，文件中的外部数据会引发错误

Question

我正在尝试读取包含2,000个值的文本文件，但我的where子句会抛出错误。

    SELECT mac.mac_id,mac.mac,mac.mac_type,record.soc_id 
    from mso_charter.mac
    where record.soc_id in ('C:\Users\xyz\worldbox2_Prod_09-17-2017.txt')
    join mso_charter.record on mac.record_id = record.header_id;

    ERROR:  syntax error at or near "join"
    LINE 4: join mso_charter.record on mac.record_id = record.header_id;
            ^
    ********** Error **********

    ERROR: syntax error at or near "join"
    SQL state: 42601
    Character: 155

此：

v0.5                                      v0.6

    From worker 2:  10000               |       From worker 2:  10000
    From worker 3:  20000               |       From worker 3:  1

除非你有多个soc_Id

SELECT mac.mac_id,mac.mac,mac.mac_type,record.soc_id from mso_charter.mac join mso_charter.record on mac.record_id = record.header_id where record.soc_id in ('C:\Users\xyz\worldbox2_Prod_09-17-2017.txt');

不是这个：

where record.soc_id = ('C:\Users\xyz\worldbox2_Prod_09-17-2017.txt');

编译器非常挑剔订单

• 选择
• FROM
• JOIN
• WHERE
• GROUP BY
• HAVING
• ORDER BY

虽然执行顺序是

• FROM
• JOIN
• WHERE
• GROUP BY
• 选择
• HAVING
• ORDER BY
