Here are some suggestions for me to code review the SSIS package, and if there are other better options for making bricks.A. See if the best solution is used1. Optimal view of the structure2. Solution, package, task, build, parameter naming using easy-to-read naming method3. Following the optimal design, optimization, adjustment schemeB. ConfigurationSee if all of the configurations have been successful and are able to obtain the correct configuration

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

Tags: The opening introduction to SQL profilling Task may be that many of us have not really used it in SSIS, so the use of this control may not be well understood. Let's put it another way, assuming that we have a need for some data analysis of some data in a database table, such as statistics on the length of the actual data in each column of the data table, the range of lengths, for example, statistics on the scale of non-empty fields in each data

SQL Server BI step with step SSIS 7 (end)-transaction, error output, event handling, logging As with other programs, SSIS packages need to be robust and stable to run, and such programs are reliable and scalable. SSIS provides support for the following: 1. Transaction: A package can be set to one or more transactions, or even two packages can be set to a transa

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://blog.csdn.net/downmoon/article/details/7443627), this article assumes that readers have an understanding of how the CDC works. ^_^. We complete the example in three steps: 1

When using SQL Server and SSIS to import a CSV file to a database recently (SSIS chooses FlatFileSource as the source of the data stream), you always encounter the LocaleID 4 is isn't installed on this system. this error.Later, long time found that there was a problem with the locale option selection on FlatFileSource, because the CSV file to be imported contains Chinese, so the sqlserver/ When

SSIS expression 1. Calculate the number of times a substring appears in a stringNumber of occurrences of "." In the Liang. Liang string Set the string variable to v_str SQL code Len(@[User: v_str])-(Len(Replace(@[User: v_str],".",""))/Len(".")) 2. If the current date is Saturday, the string "break" is returned; otherwise, the string "work" is returned.

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. 1. Create a test Excel file. Assume that there are four fields a B c d stored in the F: \ Excel directory.And copy many identical files.
