to_char(min(a.l_entrust_time),'HH24:mm:ss') 其中a.l_entrust_time在数据库中为number类型,如：140930，想转为14:09:30应该怎么转换

数据库number类型java String类型可以接吗? 数据库number类型java String类型可以接吗? 数据库number类型java String类型可以接吗?

最近学习mybatis时遇到问题，相关配置应该是正确的，用mysql查询也能返回结果，但是将数据源切换到Oracle时总是返回null，求教。mybatis查询日志如下： ``` Logging initialized using 'class org.apache.ibatis.logging.stdout.StdOutImpl' adapter. PooledDataSource forcefully closed/removed all connections. PooledDataSource forcefully closed/removed all connections. PooledDataSource forcefully closed/removed all connections. PooledDataSource forcefully closed/removed all connections. Created connection 174573182. Returned connection 174573182 to pool. Opening JDBC Connection Checked out connection 174573182 from pool. Setting autocommit to false on JDBC Connection [oracle.jdbc.driver.T4CConnection@a67c67e] ==> Preparing: SELECT ID id, LAST_NAME lastName, GENDER gender, EMAIL email FROM mybatis_employee WHERE ID = ? ==> Parameters: 1(Integer) <== Total: 0 null Resetting autocommit to true on JDBC Connection [oracle.jdbc.driver.T4CConnection@a67c67e] Closing JDBC Connection [oracle.jdbc.driver.T4CConnection@a67c67e] Returned connection 174573182 to pool. ``` 但是，将mybatis发送的SQL复制到数据中直接查询也能查询到该记录。mybatis能返回null，可以说明Oracle数据库连接应该是没问题的，应该是结果的包装出了问题，相关代码描述如下文，求赐教。 Oracle中mybatis\_employee表定义如下： ```SQL ID INTEGER LAST\_NAME VARCHAR2(255) Y GENDER INTEGER Y EMAIL VARCHAR2(255) Y ``` mybatis对应的查询配置如下： ```xml <select id="getEmployeeById" resultType="cn.seu.edu.Mybatis.bean.Employee" databaseId="oracle"> SELECT ID id, LAST_NAME lastName, GENDER gender, EMAIL email FROM mybatis_employee WHERE ID = #{id} </select> ``` 测试代码如下: ```java public void testEmployeeMapper() throws IOException{ // 创建SqlSessionFactory对象 InputStream inputStream = Resources.getResourceAsStream("conf/mybatis-config.xml"); SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream); // 创建session SqlSession sqlSession = sqlSessionFactory.openSession(); Assert.assertNotNull(sqlSession); try { // 获取接口的实现类对象 // Mybatis会为接口实现一个代理对象，由代理对象执行sql EmployeeMapper employeeMapper = sqlSession.getMapper(EmployeeMapper.class); // 调用接口的方法 Employee employee = employeeMapper.getEmployeeById(1); System.out.println(employee); } finally { sqlSession.close(); } } ``` Employee类定义如下 ```java private Integer id; private String lastName; private Integer gender; private String email; 以下省略setter和getter ```

在Type中创建了一个类型： create or replace type bb_ptyxztqk_Table as table of bb_ptyxztqk_type; 里面放自定义的record类型，现在要将table中的数据放置到cursor中，怎么弄？ 这样弄不行： open cur for select r_index, r_name, r_this, r_last, r_minus from table(cast(obj_type_tab AS bb_ptyxztqk_type)); 求大神指点！ 整体代码： 类型： create or replace type bb_ptyxztqk_Table as table of bb_ptyxztqk_type; create or replace type bb_ptyxztqk_Type as object( d_index number, d_name varchar2(100), d_this number, d_last number, d_minus number ); sql： PROCEDURE pro_getdata(enddate in varchar2, cur out type_cursor) is Type RecType Is Record( r_index number, r_name varchar2(100), r_this number, r_last number, r_minus number); Type TabType Is Table Of RecType Index By Binary_Integer; myTab TabType; obj_type_tab bb_ptyxztqk_table := bb_ptyxztqk_table(); l_index number := 1; begin if (l_index = 1) then myTab(l_index).r_index := 1; myTab(l_index).r_name := '上线单位'; myTab(l_index).r_this := 123; myTab(l_index).r_last := 456; myTab(l_index).r_minus := 333; end if; l_index := myTab.First; for l_in in l_index .. myTab.count Loop obj_type_tab.EXTEND; obj_type_tab(obj_type_tab.LAST) := bb_ptyxztqk_type(myTab(l_index).r_index, myTab(l_index).r_name, myTab(l_index).r_this, myTab(l_index).r_last, myTab(l_index).r_minus); l_index := myTab.Next(l_index); end Loop; open cur for select r_index, r_name, r_this, r_last, r_minus from table(cast(obj_type_tab AS bb_ptyxztqk_type)); end;

我从本地导出一个库dmp，然后新建一个用户，再导入库，在同一表里面同一个字段， 有的数据是正确的，有的数据就编程科学计数了

最近在用mybatis-generator通过数据库生成表格，感觉很方便，但有个问题解决不了。我用的是Oracle数据库，我的主键是Integer类型的。然后生成的Entity类的，主键类型是BigDecimal。在配置里面这个配置的是false。 <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> 官方的解释是 如果精度大于零,或长度大于18，java.math。将使用BigDecimal类型 如果精度是零,和长度是10到18之间,然后解析器将替代java.lang.Long的Java类型。 如果精度是零,和长度是5到9,那么Java类型解析器将替代java.lang.Integer。 如果精度是零,和长度小于5,那么Java类型解析器将替代java.lang.Short。 但我这个主键是Integer类型的，我是通过powerdesigner设计的，无法写长度。 就问，这个怎么转成Integer类型。是不是需要把powerdesigner设计成number精度怎么定义？还是其他什么。主键想用序列还没生成，对oracle不太熟悉

本人小白，我在创建基于存储过程的数据块时，第一次按照网上的教程，依葫芦画样创建成功后，运行也成功，但是手贱没有保存，也因为脑残有点飘，第二次自己创建时出现问题，后续把第一次成功做的样例拿出来再对照编写时，不断报错，最后重新把第一次做的样例拿出来已经无法运行，所以来此请教各位大佬。 先把我参考的网址挂出来：https://blog.csdn.net/weixin_33915554/article/details/85448269 接下来，我说一下问题： 我在Oracle的PL/SQL Developer中创建了一个Package: hek_ar_reciept_pg 包中代码贴出来如下： ``` create or replace package hek_ar_reciept_pg is type line_record_type is record( LINE_ID NUMBER, HEADER_ID NUMBER, CUSTOMER_TRX_ID NUMBER, APPLY_ACCOUNT NUMBER, APPLY_DATE DATE, GL_DATE DATE, DISCOUNT NUMBER, REVERSAL_GL_DATE DATE, AMOUNT_APPLIED_FROM NUMBER, MATCH_FLAG VARCHAR2(30), APPLY_FLAG VARCHAR2(10), TRX_NUMBER VARCHAR2(30), INSTALLMENT NUMBER, AMOUNT_DUE_REMAINING NUMBER, INVOICE_CURRENCY_CODE VARCHAR2(15), CUSTOMER_NUMBER VARCHAR2(30), CUSTOMER_ID NUMBER, CUSTOMER_NAME VARCHAR2(50), TRX_CLASS_NAME VARCHAR2(4000), TRX_CLASS_CODE VARCHAR2(20), TRX_TYPE_NAME VARCHAR2(20), PURCHASE_ORDER VARCHAR2(50), CT_REFERENCE VARCHAR2(30), LOCATION_NAME VARCHAR2(40), BILL_TO_SITE_USE_ID NUMBER, STATUS VARCHAR2(30), CASH_RECEIPT_ID NUMBER, PS_CUSTOMER_TRX_ID NUMBER, TRX_BATCH_SOURCE_NAME VARCHAR2(50), DUE_DATE DATE, TERM_ID NUMBER, CUST_TRX_TYPE_ID NUMBER, PROGRAM_APPLICATION_ID NUMBER, PROGRAM_ID NUMBER, REQUEST_ID NUMBER, AMOUNT_DUE_ORIGINAL NUMBER, AMOUNT_IN_DISPUTE NUMBER, AMOUNT_LINE_ITEMS_ORIGINAL NUMBER, ACCTD_AMOUNT_DUE_REMAINING NUMBER, TRX_DATE DATE, APPLIED_PAYMENT_SCHEDULE_ID NUMBER, CREATED_BY NUMBER, CREATION_DATE DATE, LAST_UPDATED_BY NUMBER, LAST_UPDATE_DATE DATE, LAST_UPDATE_LOGIN NUMBER, ORG_ID NUMBER, ATTRIBUTE_CATEGORY VARCHAR2(30), ATTRIBUTE1 VARCHAR2(50), ATTRIBUTE2 VARCHAR2(50), ATTRIBUTE3 VARCHAR2(50), ATTRIBUTE4 VARCHAR2(50), ATTRIBUTE5 VARCHAR2(50), ATTRIBUTE6 VARCHAR2(50), ATTRIBUTE7 VARCHAR2(50), ATTRIBUTE8 VARCHAR2(50), ATTRIBUTE9 VARCHAR2(50), ATTRIBUTE10 VARCHAR2(50), ATTRIBUTE11 VARCHAR2(150), ATTRIBUTE12 VARCHAR2(150), ATTRIBUTE13 VARCHAR2(150), ATTRIBUTE14 VARCHAR2(150), ATTRIBUTE15 VARCHAR2(150) );

Description A group of more or less domesticated bovine animals (hereafter to be referred to as cattle) are to be loaded into railway freight cars of certain train. The train consists of K freight cars (and a locomotive, which is kind of irrelevant to this problem), which can be loaded with at most M animals each. A number from 1 to N is painted on each animal (all numbers are used and no two animals carries the same number so by easy induction on N one concludes that there are exactly N animals). The animals are patiently waiting to be loaded in a queue sorted by their numbers in ascending order (1 is the first to be loaded etc.). One freight car is loaded at a time by arbitrary number of animals (not exceeding M, of course) from the beginning of the queue and then locked so no subsequent load of animals to that freight car is possible. The process of loading is continued until all freight cars are locked. It is known that some clashing pairs of animals dislikes each other and if loaded in the same freight car then the stronger one will attempt to kill the other. It is also known that there are friendly pairs of animals where the stronger animal will always successfully protect the weaker one from attack of any other animal. If no alive friendly protecting animal is present, the attack of stronger animal of a clashing pair is always successfull. All attacks in a freight car starts when it is locked. The transportation lasts long enough for all attacks to finish. Write a program that will suggest the loading of animals to the freight cars so that the number of alive animals at the end of transportation will be as large as possible. Input The first line of the input contains three integers N, K, M; 1 <= N,K <= 1000, 1 <= M <= 20. The second line contains integer D – the number of clashing pairs among the animals. Each of the following D lines contains three mutually different integers A, B, C. The pair (A, B) represents a clashing pair, and the pair (C, B) represents a friendly pair of animals. The second animal in each pair is always the weaker one. A stronger animal of a clashing pair cannot be a weaker animal in any other pair (the first number A cannot occur as a second number anywhere). A weaker animal of a clashing pair has exactly one friendly protecting animal (the third number C is uniquely determined by the first two numbers A and B). Output The first and only line of the output consists of an integer – the maximal number of alive animals at the end of transportation. Sample Input 5 2 3 2 1 2 3 1 3 2 Sample Output 5
