basic Syntax in sql server

Hi ,

           SQL is followed by unique set of rules and guidelines called Syntax. This Article gives
you a quick start with SQL by listing all the basic SQL Syntax: All the SQL statements start
with any of the keywords like SELECT, INSERT, UPDATE, DELETE, ALTER, DROP,
CREATE, USE, SHOW and all the statements end with a semicolon (;). Important point
to be noted is that SQL is case insensitive which means SELECT and select have same meaning
in SQL statements but MySQL make difference in table names. So if you are working with
MySQL then you need to give table names as they exist in the database.

SELECT Statement:

SELECT column1, column2....columnN FROM table_name;

DISTINCT Clause:

SELECT DISTINCT column1, column2....columnN FROM table_name;

WHERE Clause:

SELECT column1, column2....columnN FROM table_name WHERE CONDITION;

AND/OR Clause:

SELECT column1, column2....columnN FROM table_name WHERE CONDITION-1 {AND|OR} CONDITION-2;

IN Clause:

SELECT column1, column2....columnN FROM table_name WHERE column_name IN (val-1, val-2,...val-N);

BETWEEN Clause:

SELECT column1, column2....columnN FROM table_name WHERE column_name BETWEEN val-1 AND val-2;

Like :

SELECT column1, column2....columnN FROM table_name WHERE column_name LIKE { PATTERN };

ORDER BY :

SELECT column1, column2....columnN FROM table_name WHERE CONDITION ORDER BY column_name {ASC|DESC};

GROUP BY :

SELECT SUM(column_name) FROM table_name WHERE CONDITION GROUP BY column_name;

COUNT :

SELECT COUNT(column_name) FROM table_name WHERE CONDITION;

HAVING :

SELECT SUM(column_name) FROM table_name WHERE CONDITION GROUP BY column_name HAVING (arithematic function condition);

CREATE TABLE Statement::

CREATE TABLE table_name( column1 datatype, column2 datatype, column3 datatype, ..... columnN datatype, PRIMARY KEY( one or more columns ) );

DROP TABLE Statement::

DROP TABLE table_name;

CREATE INDEX :

CREATE UNIQUE INDEX index_name ON table_name ( column1, column2,...columnN);

DROP INDEX :

ALTER TABLE table_name DROP INDEX index_name;

TRUNCATE :

TRUNCATE TABLE table_name;

ALTER :

ALTER TABLE table_name {ADD|DROP|MODIFY} column_name {data_ype};

Statement (Rename):

ALTER TABLE table_name RENAME TO new_table_name;

INSERT INTO :

INSERT INTO table_name( column1, column2....columnN) VALUES ( value1, value2....valueN);

UPDATE:

UPDATE table_name SET column1 = value1, column2 = value2....columnN=valueN [ WHERE CONDITION ];

DELETE Statement:

DELETE FROM table_name WHERE {CONDITION};

CREATE DATABASE :

CREATE DATABASE database_name;

DROP :

DROP DATABASE database_name;

USE :

USE DATABASE database_name;
