无论用sqlcmd或者通过C#逻辑处理,或者还是直接在SqlServer里执行操作,个人总结大概不过可归总为这两种方式: 1,SSIS; 2,OLEDB驱动引擎。 SSIS实在也好用,现在这里先不去讨论。其中大多数人用的都是第二种方法,下面,本人也以第二种方法在SqlServer里导
无论用sqlcmd或者通过C#逻辑处理,或者还是直接在SqlServer里执行操作,个人总结大概不过可归总为这两种方式:USE [CUSTOMS] GO /****** Object: StoredProcedure [dbo].[sp_ReadXLSSource] Script Date: 11/21/2014 3:01:39 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_ReadXLSSource] @trgPath varchar(255), @trgTable varchar(255), @xlsFile varchar(255), @xlsSheet varchar(255), @xlsFields varchar(8000) AS declare @mySql varchar(8000) declare @myIntermediate varchar(8000) declare @Firstfield varchar(100) declare @FirstfieldValue varchar(100) --Lookup lastfield set @Firstfield = dbo.fnGetFirstField(@xlsFields) set @FirstfieldValue = RTRIM(LTRIM(SUBSTRING(@Firstfield,2,CHARINDEX(']',@Firstfield,0)-2))) --PRINT @FirstfieldValue --Drop table if exists set @myIntermediate = 'IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].[' + @trgTable + ']'') AND type in (N''U''))' set @mySql = @myIntermediate + ' DROP TABLE ' + @trgTable exec(@mySql) --PRINT @mySql --Load Table set @mySql = 'SELECT ' + @xlsFields + ' INTO ' + @trgTable + ' FROM OPENROWSET(''Microsoft.ACE.OLEDB.12.0'', ''Excel 12.0;DATABASE=' + @trgPath + '\' + @xlsFile + ';IMEX=1'', ''Select * from ' + @xlsSheet + ''')' + 'WHERE NOT ' + @Firstfield + ' IS NULL' --PRINT @mySql exec(@mySql)存储过程:sp_ReadSource
