Question

我正在尝试将数据从一个SQL表插入另一个SQL表。问题是列具有不同的数据类型。当我使用Cast（）时，我仍然收到以下错误消息：

[Msg 8114，Level 16，State 5，Line 3将数据类型varchar转换为bigint时出错。]

Table1列的数据类型为bigint或int，而Table2列为varchar。有什么建议吗？

这是我的问题：

INSERT INTO Table1 
        ([RowId],
         [Scenario],
         [Entity],
         [Project],
         [TimePeriod])

SELECT Cast([ProjectMgrID] as bigint), Cast('ACT' as bigint), 
Cast('APP' as bigint), Cast([Project] as bigint), Cast('201801' as int)
FROM Table2

使用此

INSERT INTO Table1 
        ([RowId],
         [Scenario],
         [Entity],
         [Project],
         [TimePeriod])

SELECT Cast([ProjectMgrID] as bigint), Cast([ACT] as bigint), 
Cast([APP] as bigint), Cast([Project] as bigint), Cast('201801' as int)
FROM Table2

您要将字符串转换为bigint Cast('ACT' as bigint), Cast('APP' as bigint)，您应该在[]

中提供列名称
