Recently, I tried to use sqlserver2005 integrate services to extract data from heterogeneous databases and use the ODBC-connected teradata as the data source. Refer to the "SQL Server 2005 database development details" (Electronic Industry Press Hu baijing Yao Qiao Mei) P361-363, the operation steps in SSIs are as follows:
(1) Right-click the Connection Manager and choose create connection> ODBC to create
Scenario We hope we can select the parameters when executing the package. In this case, we can use the environment variables. In addition, all the packages can use the environment variables, which is more convenient when there are a large number of packages. Step 1: Create an SSIS package Create the oledb source and flat file destination Connection Manager in the data flow task. Step 2: Configure parame
When using the SharePoint list for data storage, data integration with other systems is really a big challenge. The first thing that comes to mind is to call the WebServices and Lists provided by SharePoint. the GetListItems method of asmx, but the encoding amount ...... I don't think there are too many people who like to write code. The most important thing is that when I want to call WebService components in SSIS, the WebServices provided by SharePo
