When the SSIS error is: "Cannot convert between Unicode and non-Unicode string data types", consider implementing it with a data converter, as simple as:The first step is to find the data converter:The second step is to edit the data converter:The third step: Edit the target mapping relationship is "copy of XXX", you can.Error exclusion, success.Note: The data Connection Manager for SSIS is best used for SQ
1. Export conversion component
Export column conversion reads data from the data stream and inserts the data into the specified file. the secondary conversion uses paired data columns: one column is the data to be output, and the other column is the files to which the data is output. during conversion, data is inserted into the specified file. if these files do not exist, the conversion creates these files and then writes the data to the files. the data to be written must be of the dt_text, dt_n
The last time we introduced simple data export and import, we only operate on a single file. If we want to import data to all the files under a directory at the same time, how can we achieve this? SSIS provides the foreach loop container in the control flow, which is easy to understand. Compared with the sequential container, SSIS can traverse and execute cyclically, you can repeatedly execute the control f
The transpose of columns in SSIS is somewhat different from that in tsql.
I. first look at the row and column transpose in tsql
See the following table.
Insert test data into the table
The following result is returned if username is column:
You can do it through the following tsql (refer to msdn: http://msdn.microsoft.com/zh-cn/library/ms177410.aspx for the explain syntax)
Select [a] As a, [B] as B, [c] As cfrom (select usernam
An expression is a combination of elements to generate a unique value. These elements include variables, literal faces, functions, stored procedures, and operators. The expression of a short answer is 1
Many tasks in SSIs support expressions. All tasks support attribute configuration using expressions. For example, expressions can be used in for loop and foreach loop to set loop conditions. The derived Column task can use expressions to define outp
SSIS is not only an ETL tool, but it's very powerful. Take its WMI data Reader task and the event watcher task to get even a lot of information about the operating system. Windows Management Specification (Windows Management Instrumentation) is one of the top secrets in Windows. WMI uses WQL queries to complete the following applications:
1. Read the System event log to find a specific error
2. Query running list of applications
3. Query how much m
SSIS (SQL Server integration Services) is a platform for generating enterprise-class data integration and Data transformation solutions. Using Integration Services solves complex business problems by copying or downloading files, sending e-mail to respond to events, updating the Data Warehouse, purging and mining data, and managing SQL Server objects and data. These packages can be used independently or in conjunction with other packages to meet compl

You can use SSIS to customize a task by importing the sql2005 of Excel files in one directory (which can include subdirectories). The following is a complete description of the entire process with a large number of pictures.

Scripting SSIS is more powerful than the DTS log schema, and you don't need to write a msgboxes to get the log information you need.
Because your script component is inherited from a scriptcomponent component with a log method, this method allows you to return a message to the SSIS package's log, which triggers a scriptcomponentlogentry call, such as the following code(VB code)Dim x (0) as ByteMe.Log ("Hell

Container
A container is an object that provides a structure for one or more tasks. For example, you can execute a loop until the boundary condition is reached, or organize a series of tasks logically. A container can also contain other containers. Containers and tasks are also placed in the Control Flow Label. There are four types of containers: Task host, sequence, for loop, and foreach loop.
Task host containers
The task host is the default container of a single task. You cannot find
We will introduce the first container in SSIs 2008: For Loop container,This container is not used in many practical applications, but it is useful in some special scenarios. It is used to realize the loop of a variable and assign values to the variable in the loop. When the condition for terminating the loop is metIt exits the loop. Its function is similar to the do while structure of the structured programming language. For example, the following str
Illustration: SSIS batch import of Excel files
Import an Excel file with the same structure in a directory (including sub-Directories) to sql2005 in batches. You can use SSIS to customize the task. A large number of images are used below to describe the entire process.

Yesterday, a friend encountered a problem when developing SSIs in a 64-bit environment:
The Excel Connection Manager is not supported in the 64-bit version of SSIs, as no ole db Provider is available.

Problem Description:
When you import data from other databases, or other data sources such as text files to the destination database, you sometimes want to be able to implement the "update when data is present, when it does not exist," in the process of importing.
In the past, it is common to import a temporary table and then judge processing to import the formal table, in SQL Server 2005, SSIS can complete this processing directly when importing proc

Because of the project needs, we will read some configuration data from SharePoint, and it is possible to perform some writeback operations to update the SharePoint data. No such operation has been done before, and some should be programmed to get or write some data through C #. Looking at some of the relevant articles, I also started to test how to access the SharePoint list in SSIS Package and write data to the SharePoint list.
