以下代码需要5-6小时才能获得数年的数据（850,000条记录）。运行一个月的时间要少得多。
首先，在这个脚本中有什么明显的东西可以解释缓慢。我是否可以做任何测试来确定缺陷的位置。我发现它只需要（目前）5个小时来将数据从一组表移动到另一个表中。
是否有其他方法可以在每月运行此脚本之外使用？
开头的大选择语句需要几秒钟才能解决问题。

答案 0 :(得分：1)
您可以对脚本进行大量改进。
WHERE子句中有太多子查询。
下面的子查询可以分配给变量，并且不需要子查询：
WHERE TRANSACTION_HEADER.EXTRACT_ID = ( SELECT MAX(EXTRACT_ID)
FROM dbo.CDO_CDS_62_OPS_020_00_TRANSACTION_HEADER)
分配CONVERT（CHAR（10），GETDATE（），120）的结果，而不是在WHERE子句上使用CONVERT函数。
在下面的删除中，执行JOIN而不是子查询，这将使您的删除更快。
-- Added 13/01/2016 (PJ) Delete non-RWA activity
DELETE FROM [CHH-SLAMDB].SLAMS_SQL.dbo.tblOutpatientData
WHERE LocalClinicCode IN (SELECT CLINIC_CODE COLLATE SQL_Latin1_General_CP1_CI_AS
FROM HealthBI.dbo.CDO_CLINIC_OR_FACILITY
WHERE LOCAL_ORGANISATION_CODE_TRUST <> 'RWA')
在下面的更新中执行相同的操作。子查询上的SELECT DISTINCT可能会占用您的处理时间。
