ORA-01461: 仅能绑定要插入 LONG 列的 LONG 值。ojdbc8版本23.2.0.0驱动BUG【已解决】

问题描述

JDK8使用ojdbc8驱动操作oracle11g数据库，使用JDBC复用 PreparedStatement 对象执行Insert操作时，报错java.sql.SQLException: ORA-01461: 仅能绑定要插入 LONG 列的 LONG 值。，经测试发现，是预编译对象某个占位符号被赋值为NULL后，再次尝试赋值为2个汉字，执行时就会报错：

问题复现

测试表DDL

sql 复制代码

CREATE TABLE "TEST_TABLE" (
  "TEST_COLUMN" VARCHAR2(255 BYTE)
)

java代码

java 复制代码

   @Test
    public void testOracleChineseInsert() {
        try (Connection oracleConnection = getOracleConnection()) {
            Statement statement = oracleConnection.createStatement();
            statement.execute("truncate table TEST_TABLE");
            PreparedStatement preparedStatement = oracleConnection.prepareStatement("INSERT INTO TEST_TABLE VALUES (?)");
            List<String> list = new ArrayList<>();
            list.add("你好");
            list.add(null);
            list.add("你好");
            for (String data : list) {
                try {
                    preparedStatement.setString(1, data);
                    preparedStatement.executeUpdate();
                } catch (SQLException e) {
                    throw new RuntimeException(e);
                }
            }
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

ORACLE数据库字符集

sql 复制代码

-- 查询字符集
SELECT * FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET');
-- 查询结果
NLS_CHARACTERSET	ZHS16GBK
NLS_NCHAR_CHARACTERSET	AL16UTF16

依赖版本

xml 复制代码

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>23.2.0.0</version>
</dependency>

执行结果

前两条记录能新增成功，第三条记录报错 ORA-01461: 仅能绑定要插入 LONG 列的 LONG 值

解决办法

更换驱动版本后发现该BUG已被修复，更新驱动版本（推荐）

xml 复制代码

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>23.6.0.24.10</version>
</dependency>

或者代码中避免复用预编译对象，每个语句新建一个预编译对象（不推荐）

java 复制代码

   @Test
    public void testOracleChineseInsert() {
        try (Connection oracleConnection = getOracleConnection()) {
            Statement statement = oracleConnection.createStatement();
            statement.execute("truncate table TEST_TABLE");
            List<String> list = new ArrayList<>();
            list.add("你好");
            list.add(null);
            list.add("你好");
            for (String data : list) {
                try {
            PreparedStatement preparedStatement = oracleConnection.prepareStatement("INSERT INTO TEST_TABLE VALUES (?)");
                    preparedStatement.setString(1, data);
                    preparedStatement.executeUpdate();
                } catch (SQLException e) {
                    throw new RuntimeException(e);
                }
            }
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }
