Question

这是我第一次创建存储过程而且我不知道我做错了什么。

我收到以下错误：

Msg 7202，Level 11，State 2，Procedure update_call_details，Line 8
无法找到服务器＆＃39; SELECT TOP 1 b＆＃39;在sys.servers中。验证是否指定了正确的服务器名称。如有必要，执行存储过程sp_addlinkedserver以将服务器添加到sys.servers。

存储过程：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[update_call_details] 
AS
BEGIN
    DECLARE @EventTime varchar(50)

    SET @EventTime = 'SELECT TOP 1  b.event_time FROM db1.dbo.TableName as b order by b.event_time desc'

    EXEC @EventTime

    INSERT INTO Sdb1.dbo.TableName
        SELECT 
            CAST(START_TIME as DATE) as START_TIME,
            AGENT_ID,
            GRP_DBID,
            DIRECTION,
            ANI, DNIS, TRACKNUM,
            N_HOLD, T_HOLD,
            N_CONFRENCE, T_CONFRENCE,
            N_TRANSFER, T_TRANSFER,
            T_WRAP_UP,
            TALK_TIME,
            CAST(END_TIME as DATE) as END_TIME,
            CAST(EVENT_TIME as DATE) as EVENT_TIME
        FROM 
            OPENQUERY(db2, 'SELECT * FROM db2.TableName 
                            WHERE EVENT_TIME > "@EventTime"')
END

Answer 1

更改行： -

DECLARE @EventTime varchar(50)

到

DECLARE @EventTime varchar(200)

变量的大小正在截断其内容，因此EXEC命令失败。我已经增加了变量的大小，希望能够涵盖您可能做出的任何其他更改。

Answer 2

您无法使用openquery之类的参数。您的查询必须是单个字符串文字。

在这种情况下，您只需将EventTime子查询直接放入内联：

即可

ALTER PROCEDURE [dbo].[update_call_details] 
AS
BEGIN
INSERT INTO Sdb1.dbo.TableName
SELECT CAST(START_TIME as DATE) as START_TIME,
AGENT_ID,
GRP_DBID,
DIRECTION,
ANI,
DNIS,
TRACKNUM,
N_HOLD,
T_HOLD,
N_CONFRENCE,
T_CONFRENCE,
N_TRANSFER,
T_TRANSFER,
T_WRAP_UP,
TALK_TIME,
CAST(END_TIME as DATE) as END_TIME,
CAST(EVENT_TIME as DATE) as EVENT_TIME
 FROM openquery(db2, 
    'SELECT * 
    FROM db2.TableName 
    WHERE EVENT_TIME > 
        (SELECT TOP 1 b.event_time 
        FROM db1.dbo.TableName as b 
        order by b.event_time desc)')
END

否则......要在查询中使用参数，您可以使用此问题中的一个选项：including parameters in OPENQUERY

存储过程的SQL错误找不到服务器
