In this article we look at Transact SQL and look at its 9 practical applications
SQL basically stands for Structured Query Language meaning SQL server makes use of a structured language for taking in queries and sending relevant information. All RDBMS make use of a standard query language for processing data, but not all of them necessarily use the same language. Many software have taken from SQL, and modified it a bit, turning it into another language for their software. T-SQL has been created by Microsoft, exclusively for SQL Server, one of the most secure and trusted software for managing enterprise level databases.
Basics about T-SQL
T-SQL is the only language that can be used with SQL Server, all other applications that need to be used along with SQL Server, will also have to send data in T-SQL to SQL Server instance, so that the application can process the query. T-SQL is no ordinary language, it provides users with more than just making sense of the existing functionalities, it allows for multiple programming extensions so that the developer has scope for implementing sophisticated logic in the server. The language also allows the user to control access to data, provides statements declaring relational integrity (DRI) and also defines business roles to be implemented at server level.
Uses of T-SQL
T-SQL is the primary language for the user to communicate with the relational database. It not only acts as a tool for communication but also allows the user to make maximum use of the application by making use of all the given tools and features. It makes using databases easier for the user, but that will be possible only if you are well versed with the language. There are multiple tutorials and books available, which can be referred for better understanding T-SQL. Through T-SQL, the user tells the database whether it wants to insert, delete, edit, update etc, any given filed or feature, it provides the users with an interface that helps them manage the database.
Which are the applications that can use T-SQL
There are multiple applications that you might want to use with SQL server, here are a few of the applications that can generate T-SQL.
- Productivity applications for general office use.
- Applications making use of GUI, allowing users to make a selection of tables and columns they want to obtain data from.
- Application using a general language for user inputs.
- Business applications storing data in SQL databases, these applications can either be in-house or those purchased from the vendors.
- The script of T-SQL makes use of sqlcmd for running utilities.
- Applications that make use of other Microsoft created computer languages, like – Microsoft Visual Basic, C++, J++, etc.
- The web pages which can extract data from SQL databases.
- Distributed database systems used for replicating SQL data in other databases within the application, distributed queries waiting to be executed.
- T-SQL can be used to detach a corrupted or damaged SQL Server file.
