SQL 错误：无关的输入 ')' 期望 AS 接近 '<EOF>'

Question

当我尝试获取month_diff时收到以下错误

extraneous input ')' expecting AS near '<EOF>'

这是SQL代码

months_between((cast(min(bs.cpd_dt)) as date), cast(bs.first_prd_cpd_dt as date)) as month_diff

谁能帮我看看错误在哪里？

Answer 1

您的括号在多个地方不平衡。使用这个版本：

months_between(
    cast(min(bs.cpd_dt) as date),
    cast(bs.first_prd_cpd_dt as date)
) as month_diff

或者，作为单行：

months_between(cast(min(bs.cpd_dt) as date), cast(bs.first_prd_cpd_dt as date)) as month_diff
