Class HPT4Clob

java.lang.Object

com.hp.t4jdbc.HPT4Lob

com.hp.t4jdbc.HPT4Clob

All Implemented Interfaces:

java.sql.Clob

public class HPT4Clob

extends HPT4Lob

implements java.sql.Clob

The HPT4Clob class implements the Clob for the SQL CLOB type. An SQL CLOB is a built-in type that stores a

Character Large Object as a column value in a row of a database table. By default drivers implement a Clob object

using an SQL locator(CLOB), which means that a Clob object contains a logical pointer to the SQL CLOB data rather

than the data itself.

The Clob interface provides methods for getting the length of an SQL CLOB (Character Large Object) value, for

materializing a CLOB value on the client, and for searching for a substring or CLOB object within a CLOB value. Methods

in the interfaces HPT4ResultSet, HPT4CallableStatement, and HPT4PreparedStatement, such as getClob and

setClob allow a programmer to access an SQL CLOB value. In addition, this interface has methods for updating a CLOB

value.
