When we export data from SQL server table to excel file by using SQL Server integration service package, data in excel file column exports into text format. Even though the column values are Integer or Decimal, it is stored in text format. For example, I am retrieving the values of “CreditLimit” column from the product table. Data format changes automatically and stores in text format in excel file.

Conditional Split Transformation: Export Data from SQL Server into Oracle and MySQL Databases
In this article, I have explained how we can divide and export data of SQL Server database table into Oracle and MySQL databases. That process is based on the condition defined in SSIS as “conditional split transformation”. Conditional split transformation is like case statement of any programming language. Using conditional, we can redirect the output of a component in multiple destinations that is based on a condition defined in the conditional split component. Read More
Export data from SQL Server to Excel and Text file via using SSIS package
While using the SSIS data flow, we can perform ETL task that can be used for data migration, data offloading, design and implementation of the data warehouse.
In this article, I explain how to export data from an SQL table to excel and text file by using the SSIS data flow task.
In this demo, I will perform through the following steps:
1. Create an SSIS package and create ADO.NET connection manager.
2. Create data flow task that has ADO.NET source to populate data from SQL Server. Data will be written to excel file and text file hence configure flat file destination and excel destination.
3. Execute SSIS package and verify that data was written to excel and text files.

Exporting Oracle Table to Excel Worksheet
In this article, I will explain how we can divide and export data of an Oracle database table into multiple worksheets of an Excel file with help of the SQL Server integration service package.
Often, DBAs asked to generate Ad-Hoc reports from a database. Recently I have been asked to generate a report from the database. They want me to provide a report in multiple worksheets of an Excel file. There are different ways to do it but the query was resource-intensive. Hence I want to extract data from the database with one execution and decided to use the SQL Server integration services package. SQL Server data tools have one component called Conditional Split Transformation which can be used to achieve the task. Read More
Registered Server, a Hidden Gem of SQL Server Management Studio. Part 2
In my previous article, I have covered the following topics:
- What are Registered Servers and their usage.
- How to create and configure a Local Server Group and Central Management Studio.
In this article, I am going to demonstrate how to execute a query on multiple servers using Registered Servers. Also, I am going to cover how we can evaluate the database policy on multiple database servers using Registered Servers. Read More
Registered Server, a Hidden Gem of SQL Server Management Studio. Part 1
Managing numerous database servers in an organization is difficult. Either we must maintain a list or maintain an Excel file that has a list of database servers. To retrieve basic information about SQL Instance or databases, DBA must query on individual database servers. If a developer wants a DBA to execute an SQL Script on all database servers, DBA must review the list of servers and execute them one by one, which is time-consuming and error-prone. It might happen that DBA missed any server where it was required to execute. Imagine the cases when DBA must execute the script on specific database servers. It becomes very painful. This task can be performed using the PowerShell scripts but again, it requires some complex PowerShell coding. This task can be managed more efficiently using “Registered Servers”. Read More
Performing Data Changes Audit Using Temporal Table
SQL Server 2016 has introduced a feature called ‘System versioned temporal table’. Using normal table, you can retrieve current data; while using a system-versioned temporal table, you can retrieve data which was deleted or updated in the past. To do that, a temporal table will create a history table. The history table will store old data with “start_time” and “end_time”. Which indicates a time period for which the record was active.
