无法使用JDBCTemplate插入扩展VARCHAR2

Question

The need arose to store in excess of 4000 bytes into VARCHAR2 in Oracle database. The workaround was to engage the 'Extended Data Types'on the database to increase capacity. I am storing a maximum of 2000 characters but the special characters I'm inserting are up to 3 bytes each.

http://docs.oracle.com/database/121/SQLRF/sql_elements001.htm#SQLRF55623

Manual insertion using SQLDeveloper or a SQL statement works fine . Tested with 2000 characters / 6000 bytes.

However, when attempting to insert any String over 4000 bytes using NamedParameterJdbcTemplate, I receive the following error:

Caused by: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

This leads me to believe that it is a driver issue of some type. I'm using dependency:

    <dependency>
        <groupId>com.oracle.weblogic</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>10.3.6.0</version>
    </dependency>

Code:

@Override
public Number createRecord(Number incidentId, String type, 
String verbatim, String createdBy) {
     MapSqlParameterSource parameters = new MapSqlParameterSource();
     parameters.addValue(MyConstants.MAP_VERBATIM, verbatim);
     namedTemplate.update(insertRecordSql, parameters, key, new 
     String[]{"VERBATIM_ID"});
     return key.getKey();
}

Column definition:

"VERBATIM" VARCHAR2(2000 CHAR) NOT NULL ENABLE

Your maven entry looks strange. You are trying to utilize oracle 12c enhancement but still, you are using jar from oracle 10 <version>10.3.6.0</version> . Moreover if you jdk is higher than jdk6 you probably you have to use ojdbc7
