Working with Cassandra<\/h3>\n

CREATE KEYSPACE<\/strong><\/p>\n

A keyspace is nothing but an object which holds the information of column family user defines the data type. In RDBMS we have a database but in Cassandra we have keyspace.<\/p>\n

Syntax:<\/strong><\/p>\n

Create keyspace test with replication={\u2018class\u2019:SimpleStragey\u2019,\u2019replication_factore:3};<\/p>\n

A keyspace is created now<\/p>\n

To verify<\/p>\n

Syntax:<\/strong> DESCRIBE keyspaces;<\/p>\n

CREATING TABLE<\/strong><\/p>\n

Syntax:<\/strong> Creating table student<\/p>\n

(<\/p>\n

Student_name text Primary key,<\/p>\n

Std_age int,<\/p>\n

Std_address text,<\/p>\n

Std_phonevarint);<\/p>\n

INSERTION OPERATION<\/strong><\/p>\n

Syntax :<\/strong> INSERT into(student_name,std_age,std_address,std_phone) values(\u2018H kumar\u2019,25,Bangalore,909090909);<\/p>\n

ALTERTABLE<\/strong><\/p>\n

Syntax :<\/strong> Alter table student add student_email text<\/p>\n

DROP COLUMN<\/strong><\/p>\n

Syntax: ALTER TABLE STUDENT DROP(STD_AGE);<\/p>\n

TRUNCATE TABLE<\/strong><\/p>\n

Syntax: TRUNCATE Student;<\/p>\n
