Question

我正在尝试从Netsuite中的ITEM_SITE_CATEGORIES表获取数据到sql server 2016。我正在运行以下查询：

select * from  OPENQUERY (LINKEDSRVR,'select LONG_DESCRIPTION FROM ITEM_SITE_CATEGORIES');

抛出错误

OLE DB provider "MSDASQL" for linked server "NETSUITE" returned message "Requested conversion is not supported.".
Msg 7341, Level 16, State 2, Line 1
Cannot get the current row value of column "[MSDASQL].LONG_DESCRIPTION" from OLE DB provider "MSDASQL" for linked server "NETSUITE".

欢迎所有建议。

Answer 1

尝试投射您的列（并检查长度）：

select * from  OPENQUERY (LINKEDSRVR,'
select
    CAST(LONG_DESCRIPTION AS CHAR(8000)) AS LONG_DESCRIPTION
    ,LENGTH(LONG_DESCRIPTION) AS LD_LEN
FROM ITEM_SITE_CATEGORIES');

如果LD_LEN = 8000，那么您将丢失一些数据。

Answer 2

你也可以这样做。

 select LONG_DESCRIPTION FROM  LINKEDSRVRNAME.DBNAME.SCHEMANAME.TABLENAME

但是，对于常规运行查询，不建议使用Openquery，请使用同义词代替

无法获取列＃34; [MSDASQL] .LONG_DESCRIPTION＆＃34;的当前行值。来自OLE DB提供程序＆＃34; MSDASQL＆＃34;对于链接服务器： - NETSUITE
