在存储过程调用期间使用 CallableStatement 的 SQL 语句无效

Question

我有下面的代码来调用带有某些参数的存储过程。

但是它在callableStatement.execute(); 上失败并出现错误：

java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement

public void setContext(String userId, String someId, List<String> accountsList) {
        List<SqlParameter> parameters = Collections.singletonList(new SqlInOutParameter("output", Types.VARCHAR));
        log.info("executing stored procedure with user id: {}", userId);
        Map<String, Object> t =  defaultTemplate.call(connection -> {
            CallableStatement callableStatement = connection.prepareCall("STORED_PROC(?, ?, ?, ?)");
            callableStatement.setString(1, userId);
            callableStatement.registerOutParameter(2, Types.VARCHAR);
            callableStatement.setString(3, someId);
            OracleConnection oracleConnection = connection.unwrap(OracleConnection.class);
            Array array = oracleConnection.createOracleArray("SOME_TYPE", accountsList.toArray());
            callableStatement.setArray(4, array);
            callableStatement.execute();
            return callableStatement;
        }, parameters);
        log.info("Status of the stored procedure: {}", t.get("status_output"));
 }

我做错了什么？

Answer 1

你可以在调用你的过程时写call语句

CallableStatement callableStatement = connection.prepareCall("{call STORED_PROC(?, ?, ?, ?)}");

Answer 2

CallableStatement callableStatement = connection.prepareCall("STORED_PROC(?, ?, ?, ?)");

将{}放在参数周围。并在语句之前添加调用。如下所示：

CallableStatement callableStatement = connection.prepareCall("{call STORED_PROC(?, ?, ?, ?)}");
