整数的输入语法无效：“E00001”-PostgreSQL

Question

我正在尝试在PostgreSQL中实现以下代码，并出现以下错误：

select distinct *
from (
    select distinct
        vendor,lag(cast(vendor as bigint)) over (order by cast(vendor as bigint)) Previous_Vendor,
        (cast(vendor as bigint) - lag(cast(vendor as bigint)) over (order by cast(vendor as bigint))-1) Gaps_in_sequence
    from vendor_view 
    where
        vendor not like $$%A%$$ and
        vendor not like $$%c%$$ and
        vendor is not null and
        vendor not like '%-%' and
        vendor not like 'T%'
) a 
where Gaps_in_sequence > 0 and Previous_vendor is not null order by vendor;

ERROR:
invalid input syntax for integer: "E00001"

这是什么意思？我应该如何删除它？任何建议表示赞赏。
