Question

出于某种原因，运行以下代码时出现以下错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM postcodes_demographics INNER JOIN latlon1 on postcodes_demographics.postc' at line 3

我不明白我做错了什么，谢谢你提出任何建议！

INSERT INTO pslatlong
    SELECT postcodes_demographics.*, latlon1.*,
    FROM postcodes_demographics
    INNER JOIN latlon1
    on postcodes_demographics.postcode = latlon1.postcodens;

Answer 1

你有一个错误的逗号：

 SELECT postcodes_demographics.*, latlon1.*, <--- HERE

删除它。

Answer 2

如果仅删除逗号可以修复问题，我会非常惊讶。使用insert时，您应该养成明确列出所有列的习惯：

INSERT INTO pslatlong(col1, col2, . . . )
    SELECT d.col1, l.col2, . . .
    FROM postcodes_demographics d INNER JOIN
         latlon1 ll
         on d.postcode = ll.postcodens;

您需要这样做以确保为正确的列分配了正确的值，以允许自动递增列自动递增，并根据列数防止出现问题。

Answer 3

这可能有效：

INSERT INTO pslatlong
 SELECT postcodes_demographics.*, latlon1.*
 FROM postcodes_demographics
 INNER JOIN latlon1
 on postcodes_demographics.postcode = latlon1.postcodens;

mysql语句返回语法错误
