Class ProClob

java.lang.Object

com.progress.open4gl.ProClob

All Implemented Interfaces:

java.io.Serializable, java.sql.Clob

public class ProClob
extends java.lang.Object
implements java.sql.Clob, java.io.Serializable

The mapping in the Java programming language 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. The driver implements 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. A Clob object is valid for the duration of the transaction in which is was created.
