sql - sqlite查询以查找列中所有值的总和

Question

此列是 sqlite 中的价格。我正在使用SELECT SUM(price) FROM example; 但该值不正确，它只是 5 位数字，后跟 67 个数字和 6 个零和 1，例如： 34,456.670000001 。该列是作为 VARCHAR 创建的。我尝试了 numeric(100) 和 Integer，但值仍然保持不变。请指导我完成，因为我是 db 中的菜鸟。再次感谢。我非常感谢您的帮助。

Answer 1

问题是 SQLite 会在将这些字符串隐式转换为数字时截断逗号处的数字，以便对它们求和。例如：

sqlite> select '1,000' + '2,000';
'1,000' + '2,000'
3

您需要做的就是去掉逗号。您应该能够使用replace然后让 SQLite 的默认类型转换从那里获取它：

SELECT SUM(replace(price, ',', '')) FROM example

例如：

sqlite> select replace('1,000', ',', '') + replace('2,000', ',', '');
replace('1,000', ',', '') + replace('2,000', ',', '')
3000
