2 ole db SQL task
When the SQL task connection type is OLE DB, the parameter ing and usage are different.
Ing: The parameter name is no longer @ xxx, but the serial number corresponding to it in the SQL statement.
Usage:
A. It is no longer where [email protected], but Server = ?. The question mark corresponds to the parame

18. Edit the ing and link. The default value is OK.

In SSIS, a field with Identity is often introduced. The Identity field cannot be inserted. There is a stupid way to achieve this. First set the Identity field of the target data table to No, and then set it back after the data is imported. Of course, this is troublesome and error-prone. In fact, it can be done through settings.

In the SSIS advanced conversion task-export column article, we mainly export the file columns in the database. Here we will discuss how to import files to the database, it is a pair of frequently used tasks with the export Column task. When we figure out what functions they implement, we will find that the original names are more appropriate. This type of conversion converts physical files in the system file path into table data in the database, and v
A Web service task is a newly added task in SSIs. It can connect to a WebService and execute a method in the service. After the method is executed, the result can be written back to a variable or file. This task is suitable for processing information in third-party applications. For example, you can use this task to execute WebService to obtain the updated product list of Amazon and write the information to the local server.

Script tasks allow you to use the Microsoft Visual Studio environment to create and execute scripts in the VB. NET language. ActiveX tasks allow script execution from SQL Server 2000. Compared with ActiveX tasks, script tasks have some advantages. As shown below.

Easily in the scriptCodeSet breakpoint
You can pre-compile the script in binary format.

Data Flow tasks are a core task in SSIs. It is estimated that most ETL packages are inseparable from data flow tasks. So we also learned from data flow tasks.
A Data Flow task consists of three types of data flow components: source, conversion, and target. Where:
Source: it refers to a group of data storage bodies, including tables and views of relational databases, files (flat files, Excel files, XML files, etc.), and datasets in system memory.

So sometimes you have data that does not come up right in Excel because either it's not formatted, or it's got mixed types. the end of it all is you just need it to come in as text and you can convert it later. my good friend, Robert Skoglund gave me this hint and I dug up some info on it ....
Basically, add the option IMEX = 1 to the connectionstring for excel. This forces the columns to be tr
combines two sorted data sets into one dataset. Insert the rows to the output based on the values of the key columns of the rows in each dataset. The merge conversion function is similar to the Union all clause in the T-SQL statement.
Merging and conversion require that the input column have matched source data. In the SSIS designer, the merged and converted user interface automatically maps columns with metadata. You can then manually map other colu

Designing the package in a data stream, moving the core data processing to the data flow, typically reduces the creation of temporary tables, provides high processing performance, and in some cases, the use of a staging table (staging table) optimizes the package design.1, using collection-based update operationsIn large systems, data updates are usually bottleneck of the system, because SSIS cannot perform collection-based updates in data Flow.

Demand:In SSIS2012, a package that imports data from a flat file requires you to copy the file that handles the error to a dedicated folder for administrators to view.Problem Description:1. Add a parameter to the package parameter to the target folder path.2. Add a file system task to copy the error file to the specified folder. The task executes when the file processing fails.3.
