Create an ole db connection in the Connection Manager to connect to the database adventureworks. The result is as follows: 3. On the data flow tab, move an ole db source and a data conversion task. And drag the connection line (green or red arrow) from the source or previous conversion to the data conversion t

This article supporting source code The last time we introduced a simple data export and import, but only to operate on a single file, what if we wanted to perform a data import on all the files under a directory at the same time? Quite simply, SSIS provides a Foreach Loop container in the control flow, which is easy to understand, It is capable of looping traversal execution compared to a sequence container, and can repeatedly execute control flow o

demo_lk_customer SET customeraddress =? WHERE CustomerID =? In the test data, we think the IDs of both tables are unique, the 1th and 3rd data are inconsistent, and the 4th and 5th data do not exist in the target table. Take a look at the SSIS Package architecture that implements this example, and the outermost is a data flow df_lookup. In a data stream, the data source Ole_src_legacycustomer uses SQL Server database tables in this example, bu

With a few gaps in the latest projects, starting with some of the bi features of SQL Server 2012 and 2014, referring to an example from Matt, we started to experience the CDC in SSIS (change data Capture). Note: If you need to know about the CDC in SQL Server 2008, see here http://www.cnblogs.com/downmoon/archive/2012/04/10/2439462.html), This article assumes that the reader has an understanding of how the CDC works. ^_^. We complete the example in

For example, the Excel driver recognizes only a limited set of data types.

Mention Java Underwear class (Innerclass) A lot of people are not familiar with, actually similar concept in C + + also has, that is nested class (Nested Class), about the difference between the two, there will be a comparison in the following. The inner class, on the surface, defines a class in a class (as you can see from the inside class, which can be defined in many places), but it's not as simple as it might seem, and his usefulness may not be so obvious to beginners, but with his deep unde

There are roughly 5 types of relationships between classes: 1, dependency relationship (Dependency) One-way, which indicates that one class relies on the definition of another class, where the change of one class affects the other class, and is a "use a" relationship If a depends on B, then B behaves as a local variable, method parameter, static method call, etc. public class Person {public void dosomething () { card = new Card ();//local variable

Nested classes, internal classes, static internal classes in Java, and java nestingIn Java, we define another class within a class, as shown below: class OuterClass { ... class NestedClass { ... }}In the preceding example, OuterClass is called the external class (enclosing Class), and the class in it is called the Nested Class ). There are two ty
