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

测试表DDL
CREATE TABLE TEST_TABLE (TEST_COLUMN VARCHAR2(255 BYTE)
)java代码 Testpublic 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 (?));ListString 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

/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
dependencygroupIdcom.oracle.database.jdbc/groupIdartifactIdojdbc8/artifactIdversion23.6.0.24.10/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 Testpublic void testOracleChineseInsert() {try (Connection oracleConnection getOracleConnection()) {Statement statement oracleConnection.createStatement();statement.execute(truncate table TEST_TABLE);ListString 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);}}
