SQL is a structured query language that can be used to manipulate data in a database. There are many clauses in SQL which are used to create or alter the database.
An SQL statement is an instruction to the database software, telling it what operation you want it to perform.
SQL is a programming language which is used to store and retrieve data in a relational database management system. It is often used by software developers, database administrators, and business analysts. SQL statements are written in a case-sensitive text-based format, and can be run on the command line or inside an application program.
SQL queries are a set of instructions that tell a database how to retrieve data. There are three types of queries: SELECT, INSERT, and UPDATE.
The most popular queries are the select, insert, update, and delete statements. The select statement is used to retrieve data from one or more tables in a database. The insert statement is used to add data to a table in a database. The update statement is used to change the data in one or more tables in a database. And finally the delete statement is used to remove data from one or more tables in a database.
