SQL: SQL stands for “Structured Query Language”. The current version of SQL is “ANSI SQL – 92”. It contains constructs which are used to define and process database . They are executed using DBMS-supplied command prompt. SQL is not a programming language. It is text-based and it is also called as data sublanguage. In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on. Table Creation: Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows: CREATE TABLE TABLE_NAME ( Column1 datatype, Column2 datatype, … ); DELETE FROM statement: “DELETE FROM” statement is used in order to delete existing records (rows and columns) from the table. Note: It is necessary to use “WHERE” clause when deleting values, because, when it is ignored all the values from the mentioned column name gets deleted. Syntax: DELETE FROM table_Name WHERE condition;
