T - SQL Script

T - SQL Script

A T - SQL script is a set of Transact-SQL statements that can be executed together as a batch. A T - SQL script can perform various tasks, such as creating databases, tables, views, stored procedures, functions, triggers, indexes, and more. A T - SQL script can also manipulate data by inserting, updating, deleting, or querying records from tables or views. A T - SQL script can use variables, parameters, conditional logic, loops, error handling, and other features to make the code more dynamic and robust.

To create a T - SQL script, you need a text editor or an integrated development environment (IDE) that supports Transact-SQL syntax highlighting and formatting. You can save your T - SQL script as a .sql file and execute it using a tool such as SQL Server Management Studio (SSMS), SQLCMD utility, or PowerShell. Alternatively, you can run your T - SQL script directly from the query window of SSMS or other IDEs.

A T - SQL script typically starts with a USE statement that specifies the database context for the subsequent statements. For example:

USE AdventureWorks2019;
GO

The GO command signals the end of a batch and sends it to the server for execution. You can use GO multiple times in a T - SQL script to separate different batches of statements. You can also use comments to document your T - SQL script using two hyphens (--) for single-line comments or /* and */ for multi-line comments. For example:

-- This is a single-line comment
/* This is a multi-line comment */

Introduction to Structured Query Language

Introduction to Structured Query Language Structured Query Language (SQL) is a standard language for accessing and manipulating data in relational databases. SQL allows users to perform various operations on data, such as querying, inserting, updating, deleting, creating, and modifying tables, views, indexes, and other database objects. SQL also supports features such as transactions, constraints, triggers, functions, procedures, and user-defined types. SQL is based on the relational model of data, which organizes data into tables consisting of rows and columns. Each table has a name and a set of attributes (columns) that define the properties of the data. Each row in a table represents a record (or tuple) of data that has values for each attribute. Tables can be related to each other by using keys, which are attributes that uniquely identify a row in a table or link rows from different tables. SQL consists of several sublanguages, such as Data Definition Language (DDL), Data Manipula...
