[解決済み] NamedParameterJDBCTemplate を使用して挿入すると、「無効な列の種類です」という例外が発生する。

質問

データベース(Oracle 10g xe,jar: ojdbc14.jar)に行を挿入する際に、以下のコードを使用しています。

String sql = "INSERT INTO SPONSOR_TB(ID,NAME,INDUSTRY_TYPE,IS_REPORTING_SPONSOR,IS_NOT_SOLICITE) VALUES(SEQ_SPONSOR_ID.NEXTVAL,:NAME1,:INDUSTRY_TYPE,:IS_REPORTING_SPONSOR,:IS_NOT_SOLICITE)";

MapSqlParameterSource paramSource = new MapSqlParameterSource();
paramSource.addValue("NAME1",sponsor.getName());
paramSource.addValue("INDUSTRY_TYPE", sponsor.getIndustryType());
paramSource.addValue("IS_NOT_SOLICITE", sponsor.getNotSoliciteFlag()?'Y':'N');
paramSource.addValue("IS_REPORTING_SPONSOR", sponsor.getReportingFlag()?'Y':'N');
KeyHolder generatedKeyHolder = new GeneratedKeyHolder();
namedParameterJdbcTemplate.update(sql, paramSource, generatedKeyHolder,new String[]{"ID"});
int id = generatedKeyHolder.getKey().intValue();

テーブルの構造は

create table SPONSOR_TB
(
 id                   INTEGER not null,
 name                 VARCHAR2(20),
 industry_type        INTEGER not null,
 is_reporting_sponsor CHAR(1) not null,
 is_not_solicite      CHAR(1) not null 
)

で、SEQ_SPONSOR_ID はシーケンスです。

そしてスポンサークラスは

public class Sponsor{
      private int id;
      private String name;
      private boolean reportingFlag;
      private boolean notSoliciteFlag;
      private int industryType;
      //getter setter
}

そして、spring-servlet.xmlのdbの設定は。

 <beans:bean
    id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

    <beans:property
        name="driverClassName"
        value="oracle.jdbc.driver.OracleDriver" />

    <beans:property
        name="username"
        value="SPONSOR_DB" />

    <beans:property
        name="password"
        value="ajeet" />

    <beans:property
        name="url"
        value="jdbc:oracle:thin:@localhost:1521:XE" />
</beans:bean>

次のような例外が発生します。

 SEVERE: Servlet.service() for servlet [spring] in context with path [/GroupSolution] threw exception [Request processing failed; nested exception is org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO SPONSOR_TB (ID,NAME,INDUSTRY_TYPE,IS_REPORTING_SPONSOR,IS_NOT_SOLICITE) VALUES(SEQ_SPONSOR_ID.NEXTVAL,?,?,?,?)]; SQL state [null]; error code [17004]; Invalid column type; nested exception is java.sql.SQLException: Invalid column type] with root cause

解決方法は？

CHAR(1) Y/Nフィールドに、文字ではなく文字列を使用してみてはいかがでしょうか。
