Class SqlCharacterValue

java.lang.Object

org.springframework.jdbc.core.support.SqlCharacterValue

All Implemented Interfaces:

SqlTypeValue

public class SqlCharacterValue
extends Object
implements SqlTypeValue

Object to represent a character-based parameter value for a SQL statement, e.g. a character stream for a CLOB/NCLOB or a LONGVARCHAR column.

Designed for use with JdbcTemplate as well as JdbcClient, to be passed in as a parameter value wrapping the target content value. Can be combined with SqlParameterValue for specifying a SQL type, e.g. new SqlParameterValue(Types.CLOB, new SqlCharacterValue(myContent)). With most database drivers, the type hint is not actually necessary.

Since:

6.1.4
