So, here I want an automated SQL query to disable the completed sequence container and enable the failed sequence container so that if I run the package again, then it will. this seems to cause the sequence container to fail if i do this and if i don't retain the same connection further steps fail. Basically in Data flow i have used OLE DB source, Derived column and OLE DB Destination (i. To demonstrate, add a Sequence Container from the SSIS Toolbox to the Control Flow, and then add an Execute SQL Task from the SSIS Toolbox to the Sequence Container as shown in Figure 14:SQL Server Integration Service allows us to apply transactions at Package Level (Master Level), Task Level, or Container Level. You will need to configure all the servers involved with your process to be of DTC. Select the. ), as well as just about any Control Flow task (e.
