Question

我完全不熟悉使用MS Visual Studios和创建包。

据说，我创建了一个应该运行SQL任务编辑器的包（从Oracle数据库中提取数据），然后使用OLE DB连接的数据流任务来更新SQL Server上的表。

我的sql编辑器任务使用'变量'选项中的'sql，该变量包含在代码中的最后一个运行日期变量（变量LastRunDate应该查看SQL服务器表中的字段，以查找包的最后日期跑得很成功）。使用此日期，它应将此日期之后输入的Oracle数据库数据提取到SQL Server表中。 sql编辑器任务运行正常;但是，当调用数据流时，OLE DB Source会出错

[OLE DB Source [1]]错误：SSIS错误代码DTS_E_OLEDBERROR   发生OLE DB错误   错误代码：0x80040E14。 OLE DB记录可用   来源：“Microsoft OLE DB Provider for Oracle”Hresult：0x80040E14
  描述：“ORA-00923：找不到FROM关键字”。

我没有正确设置什么？

在SQL编辑器任务的SQL语句中：

declare @lastRunDate datetime, @lastRunDate_AsString varchar(30), 
        @sqlScript varchar(1000);

set @lastRunDate = (SELECT LastSuccessRunDate 
                    FROM dbo.LastSuccessRunDate 
                    WHERE PackageName = 'V_M_E')

set @lastRunDate_AsString = (SELECT 
                                convert(varchar(20), @lastRunDate, 101) + '
                              ' + substring(convert(varchar(20), @lastRunDate, 9), 13, 5) + substring(convert(varchar(30), @lastRunDate, 9), 25, 2)
currentdate_time)

set @sqlScript = 'SELECT ep.member_id AS MEMBER_ID,  ep.NAME_FIRST AS
                  NAME_FIRST, ep.NAME_LAST AS NAME_LAST, ep.ADDRESS1 AS ADDRESS1,

                  FROM

select @sqlScript as SQLSU

Answer 1

你在动态sql中的第二个sql中缺少FROM子句。

这是因为当您动态创建sql语句时，您的文本将被截断为1000个字符。

而不是VARCHAR(1000)使用NVARCHAR(MAX)

Answer 2

使用将超过1000个字符的字符串分配给@sqlScript varchar(1000)

数据流任务不从oracle db更新SQL Server表
