SQL SERVER Integration Service (SSIS)

What is BI(Business Intelligence)
Business Intelligence is all about converting large amount of data into useful data thereby we can easily acquire knowledge through BI analysis for the business action. A typical BI environment data-source, business model, data model, ETL, and transformation tools to organize the data into useful information.


Breakpoints in SSIS  
Breakpoint is responsible to stop execution of package when specific event occur in control flow to investigate and troubleshoot  the state of the SSIS package. Read More


Data Viewer in SSIS
Data Viewers are containers that can contain a single SSIS buffer’s work.  As the data passes through the Data Path you are able to view what is in each buffer.  As each buffer passes into the Data Viewer, the processing of the SSIS package on that Data Path is paused.  In essence, you have a breakpoint.  Read More


Variables in SSIS
according to Microsoft, Variables store values that a SQL Server Integration Services package and its containers, tasks, and event handlers can use at run time. The scripts in the Script task and the Script component can also use variables. The precedence constraints that sequence tasks and containers into a workflow can use variables when their constraint definitions include expressions. Read More...


Control Flow in SSIS 
Control flow is the collection of data flow task which is provide structure , functionality in package and connect the executables , container, task into a ordered control flow. SSIS provide three types of control flow  containers ,task, precedence containers. Read More...


Data Flow task and Data flow in SSIS 
Data flow task is the collection of data flow engine or you may say Data Flow task encapsulate data flow engine, Data Flow engine move the data from source to destination, it's give the facility to transforms and to modify data as it is moved. Read More..
 

Sort Transformation in ssis

Sort transformation responsible to arrange data in ascending or descending order and copies the data to the transformation output. Multiple sorts can be apply to an input**. The Sort transformation can also remove duplicate rows which is part of its sort. Read More..


Lookup Transformation in SSIS
Lookup transformation is responsible to join columns to the data flow/data set, by accessing additional information in a related table based on values in common columns.Read More


Merge and Merge join transformation in SSIS
Using Merge Transformation we can combines two sorted data-set into single data-set basically Merge Transformation used to combines rows from two sorted data flows into one sorted data flow based on values in common columns.Read More

Check for changes to an SQL Server table?

Problem: Suppose your team is working on the under-development project so it might be possible continuous work on the database and perform changes in Table, Stored procedure as per requirement, and daily you have to update the testing server database as per changes are done in developing server database then how it is possible to trace those changes. There are a lot of solutions for this problem which is listed below Solution 1: For SQL Server 2000, 2005 and above use the CHECKSUM command SELECTCHECKSUM_AGG(BINARY_CHECKSUM(*))FROMYour_Table_NameWITH (NOLOCK); That will return the same number each time its run as long as the table contents haven't changed. Unfortunately CHECKSUM does not work always properly to detect changes. It is only a primitive checksum and no CRC calculation. Therefore you can't use it to detect all changes, e. g. symmetrical changes result in the same CHECKSUM! Solution 2: 1.Run the following query. Before executing query replace DB_Name with your database name…

How to drop multiple tables with common prefix in one query?

Problem: Suppose we have a situation where we need to drop those tables that have some prefixes string, so it is possible to drop those tables with a common prefix in a single query.
Solution: yes it is possible to drop all those tables that have the common prefix in a single query. Using following query you can delete all those tables that begin with a certain prefix string. In where condition just put the common prefix string in where condition (Like ‘prefix%’)
DECLARE@queryNVARCHAR(MAX)=N'';
SELECT@query+=' DROP TABLE ' +QUOTENAME(s.name) +'.'+QUOTENAME(t.name)+';' FROMsys.tablesASt INNERJOINsys.schemasASs ONt.[schema_id]=s.[schema_id] WHEREt.nameLIKE'MX_100%';
EXECsp_executesql@query;
This query may create an issue, if a table has a foreign key relationship, you'll either need to drop them first or arrange the output to drop the tables in a certain order. If you want to monitor exactly what goes on when the query is running then use the following que…
