The only way to avoid LobHandler in DAO code for insert/update:
MapSqlParameterSource paramSource = new MapSqlParameterSource();
paramSource.addValue("clob", "a long long text", Types.CLOB);
namedTemplate.update(INSERT_STMT, paramSource);See:
- http://stackoverflow.com/questions/5791662/inserting-clob-with-namedparameterjdbctemplate
- http://codeblow.com/questions/placing-clob-with-namedparameterjdbctemplate/
another way (only for JdbcTemplate, not for NamedParameterJdbcTemplate):
- http://docs.spring.io/spring/docs/3.0.x/reference/jdbc.html#jdbc-lob
- http://www.java2s.com/Code/Java/Spring/InsertClobData.htm
java.sql.Types has NCLOB constans for Java 6/7/8:
- http://docs.oracle.com/javase/6/docs/api/java/sql/Types.html#NCLOB
- http://docs.oracle.com/javase/7/docs/api/java/sql/Types.html#NCLOB
If I do:
paramSource.addValue("clob", "a long long text", Types.CLOB);
all work fine, but with:
paramSource.addValue("clob", "a long long text", Types.NCLOB);
I get:

My suggestion just add NCLOB to src/main/java/org/springframework/jdbc/core/StatementCreatorUtils.java with same role as CLOB!
Affects: 3.2.9, 4.0.5
