从SQL Server批量复制到Oracle
[英]Bulk Copy from SQL Server to Oracle
问题描述
I have a requirement for a project to move data from SQL Server to Oracle in bulk mode. 
我需要一个项目以批量模式将数据从SQL Server迁移到Oracle。 There is OracleBulkCopy from DataDirect and ODP .net but to use that I have to first convert the data reader from SQL server into a CSV file and then can export that using bulk copy.This is a very inefficient process and I was wondering if there is another way.We can't use Linked servers. 有来自DataDirect和ODP .net的OracleBulkCopy，但是要使用它，我必须先将SQL Server的数据读取器转换为CSV文件，然后可以使用批量复制将其导出。这是一个非常低效的过程，我想知道是否有另一种方式。我们不能使用链接服务器。

IF you use SSIS you should be able to directly load data to an ORacle database withouthgoing through the step of creating a text file for the load. 如果使用SSIS，您应该能够直接将数据加载到ORacle数据库，而无需执行创建用于加载的文本文件的步骤。 This assumes the Oracle database is availble in your network. 假设您的网络中有Oracle数据库可用。

You can export your sql server data to a flat file or a comma separated file. 您可以将sql server数据导出到平面文件或逗号分隔的文件中。 You can use that flat file as an external table in Oracle. 您可以将该平面文件用作Oracle中的外部表。
An other solution is to create a database link from Oracle to sql server and to do 'select .. from ssss@db_link'. 另一种解决方案是创建从Oracle到SQL Server的数据库链接，并“从ssss @ db_link中选择..”。

What is your data volume ? 您的数据量是多少？
If its not too huge, then try using Access as a bridge between the two DBs. 如果它不是太大，则尝试使用Access作为两个DB之间的桥梁。
In access, map the source SQLSERVER table, and the destination ORACLE table. 在访问中，映射源SQLSERVER表和目标ORACLE表。
Read from source, and write into destination, using Access. 使用Access从源读取，然后写入目标。
