What do you understand by JDBC Statements?

JDBC statements are basically the statements which are used to send SQL commands to the database and retrieve data back from the database. Various methods like execute(), executeUpdate(), executeQuery, etc. are provided by JDBC to interact with the database.

JDBC supports 3 types of statements:

1.     Statement: Used for general purpose access to the database and executes a static SQL query at runtime.

2.     PreparedStatement: Used to provide input parameters to the query during execution.

3.     CallableStatement: Used to access the database stored procedures and helps in accepting runtime parameters.
