                CURR_YEAR                    5 VARCHAR2(4) NOT NULL

从上面的显示结果可以看到执行计划的第一步执行的是对索引IDX_LV_URBAN_TOPAY_TMP_CORP_ID执行索引范围扫描并没有使用Hint所指定的PK_LV_URBAN_TOPAY_TMP,而且从上面的显示的索引信息部分可以看到索引PK_LV_URBAN_TOPAY_TMP是由列URBAN_TOPAY_SN, INDI_ID, POLICY_ITEM_CODE, CORP_ID, CURR_YEAR组成的复合索引而查询条件没有URBAN_TOPAY_SN字段使用不了这个索引从上面的执行计划可以看到这一结果。上面执行计划中步骤28与步骤29执行哈希连接，都是全表扫描，其中步骤Id=29是对BS_INSURED执行100多万条记录执行全表扫并且将它们的结果与表BS_PERSON_TYPE执行哈希连接最后与BS_FAMILY执行哈希连接返回记录123条数据，其成本是14375，其中对表BS_INSURED执行全表扫描的成本就是14244。而执行计划执行的第一步就是访问LV_URBAN_TOPAY_TMP，而where条件中有 bi.indi_id = lt.indi_id AND bs.sex = bi.sex and pt.pers_type = bi.pers_type，且这条连接条件都存在索引,那么就不应该那对BS_INSURED，BS_SEX,BS_PERSON_TYPE,BS_FAMILY 这四个表之间进行哈希连接后再与这四个表（LV_URBAN_TOPAY_TMP，LV_BUSI_ASSIGN，LV_BUSI_RECORD，LV_BUSI_BILL）连接后的结果集之间执行哈希连接。而是应该
在这四个表（LV_URBAN_TOPAY_TMP，LV_BUSI_ASSIGN，LV_BUSI_RECORD，LV_BUSI_BILL）连接后与BS_INSURED执行嵌套循环连接，因为有where条件bi.indi_id = lt.indi_id 而且indi_id在表BS_INSURED中是主键，从上面的索引信息中可以看到IDX_LV_URBAN_TOPAY_TMP_CORP_ID索引的distinct key是996,而where条件能使用CBO选择使用该索引从执行计划的Order列为1的步骤可知首先执行的就是对索引IDX_LV_URBAN_TOPAY_TMP_CORP_ID的索引范围扫描。当LV_URBAN_TOPAY_TMP与BS_INSURED执行完嵌套循环连接后因为有where条件bs.sex = bi.sex and pt.pers_type = bi.pers_type所以对BS_SEX,BS_PERSON_TYPE,BS_FAMILY表都应该执行嵌套循环连接。

这里优化步骤是首先删除原来SQL语句中所使用的Hint”/*+ index(lt,PK_LV_URBAN_TOPAY_TMP) */”后并执行SQL语句：

从上面的执行计划可以看到，当去掉Hint”/*+ index(lt, PK_LV_URBAN_TOPAY_TMP) */”后，CBO选择的执行计划果然是先访问IDX_LV_URBAN_TOPAY_TMP_CORP_ID
来访问表LV_URBAN_TOPAY_TMP，然后因为“lbr.busi_reco_no = lba.busi_reco_no AND lbr.busi_bill_sn = lbb.busi_bill_sn AND lt.center_id = lbb.center_id
AND lt.busi_asg_no = lba.busi_asg_no ”，表LV_BUSI_ASSIGN，LV_BUSI_RECORD，LV_BUSI_BILL与LV_URBAN_TOPAY_TMP连接的列都是各个表的主键，所以会分别与这三个执行嵌套循环连接。且存在where条件bi.indi_id = lt.indi_id ,而indi_id是表BS_INSURED表的主键所以也执行嵌套循环连接。而又因为与表BS_INSURED进行表连接的列也存在相关索引因此，依次类推整个执行计划都是执行嵌套循环连接。而且从下面的执行计划信息中可以看到，整个语句的逻辑读只有96762,而原来的逻辑读为3亿多次。这可是数据量级的减少。

Note
-----
   - SQL profile "coe_36cbabzyq13gy_1849931106" used for this statement


276 rows selected.

从Note部分的SQL profile "coe_36cbabzyq13gy_1849931106" used for this statement可知SQL Profile对该SQL生效了，而且从执行计划中可知现在与去掉Hint“/*+ index(lt,PK_LV_URBAN_TOPAY_TMP) */”之后的SQL执行计划一样的。至此，对该SQL的优化也就完成。

这个SQL语句执行缓慢的原因就是因为使用了Hint"/*+ index(lt,PK_LV_URBAN_TOPAY_TMP) */"后，使CBO选择了错误的执行计划而造成的。

在进行性能优化尤其是SQL优化时不能在生产环境进行测试，或者在升级时对SQL语句性能进行测试时，构建一个测试环境很重要，这篇文章介绍使用SQLT工具来快速简单的构建测试用例的方法。其实要使用SQLT来构建一个测试用例不需要额外执行SQLT报告。运行SQLTXTRACT或SQLTXECUTE就能为测试用例创建足够的信息。

例如我要将在aix系统上Oracle 10g中运行的SQL语句在linux系统上Oracle 11g中来测试它的性能时，这就需要构建一个测试用例。要进行测试的语句如下:

select 
nvl(sum(real_pay), 0) as dYearA131
  from mt_biz_fin a, mt_pay_record_fin b, mt_apply c
 where a.hospital_id = b.hospital_id
   and a.serial_no = b.serial_no
   and a.treatment_type = '131'
   and a.indi_id = 5609194
   and a.serial_apply = 135888
   and a.valid_flag = '1'
   and b.valid_flag = '1'
   and a.serial_apply = c.serial_apply
   and c.valid_flag = '1'
   and b.POLICY_ITEM_CODE in ('C000', 'C001', 'C004')
   and exists (select 1
          from mt_pay_record_fin b
         where b.fund_id not in ('003', '999')
           and a.serial_no = b.serial_no);

为sqltxecute.sql脚本创建一个来测试的sql文件

[IBMP740-1:oracle:/oracle/sqlt/input/sample]$vi mysql2.sql

-- cd sqlt
-- #sqlplus sh

  from mt_biz_fin a, mt_pay_record_fin b, mt_apply c
 where a.hospital_id = b.hospital_id
   and a.serial_no = b.serial_no
   and a.treatment_type = '131'
   and a.indi_id = 5609194
   and a.serial_apply = 135888
   and a.valid_flag = '1'
   and b.valid_flag = '1'
   and a.serial_apply = c.serial_apply
   and c.valid_flag = '1'
   and b.POLICY_ITEM_CODE in ('C000', 'C001', 'C004')
   and exists (select 1
          from mt_pay_record_fin b
         where b.fund_id not in ('003', '999')
           and a.serial_no = b.serial_no);

NOTE:
You used the XECUTE method connected as INSUR_CHANGDE.

In case of a session disconnect please verify the following:
1. There are no errors in sqltxecute.log or sqltxecute2.log.
2. Your SQL contains token "^^unique_id" within a comment.
3. Your SQL ends with a semi-colon ";".
4. You connected as the application user that issued original SQL.
5. Script /oracle/sqlt/input/sample/mysql2.sql can execute stand-alone connected as INSUR_CHANGDE
6. User INSUR_CHANGDE has been granted SQLT_USER_ROLE.

In case of errors ORA-03113, ORA-03114 or ORA-07445 please just
re-try this SQLT method. This tool handles some of the errors behind
a disconnect when executed a second time.

To actually diagnose the problem behind the disconnect, read ALERT
log and provide referenced traces to Support. After the root cause
of the disconnect is fixed then reset SQLT corresponding parameter.

这个目录列表中有两个文件要注意。第一个sqlt_s34879_tc.zip是一个标准的测试用例文件，第二个sqlt_s34879_tcx.zip是最近才增加的（2012.12）。
1.构建测试用例的步骤
创建测试用例的第一步是在主SQLT区域创建一个子目录。然后复制sqlt_s34879_tc.zip文件到这个子目录中并进行解压。
这样会创建一些文件并且我们将对每一个进行描述。这里是一个示例列表。

在这个目录中的文件都是必要的（使用SQLT来在你的数据库中创建一个测试用例）。在下一节我们将查看这些文件的详细信息。

2.测试用例文件

目录中的脚本和其它的文件被用来简单和快速地构建一个测试用例。我列出了每一个文件和它们的描述。后面我们将看到怎样使用这些文件来构建一个真实的测试环境。
. 10053.sql—设置10053的跟踪级别为1
. flush.sql—清空共享池
. plan.sql—显示最近执行SQL的执行计划并将其输出到plan.log中，它是调用的dbms_xplan.display_cursor过程来显示执行计划
. q.sql—被调查的SQL
. readme.txt—指令。它们非常简单：例如”connect as sys and execute setup.sql”
. sel.sql—计算谓词选择性。这个脚本依赖于sel_aux.sql并且会打印出表名和谓词然后给你显示出谓词基数和选择性。下面有一个使用sel.sql的示例
. sel_aux.sql—使用sel.sql基于不同的谓词来生成预期的基数和选择性
. setup.sql—设置系统统计信息，创建测试用户和元数据，导入对象统计信息和优化器环境，执行测试查询并显示执行计划
. sqlt_snnnnn_del_hgrm.sql—删除测试用户方案的直方图信息
. sqlt_snnnnn_exp.dmp—包含统计信息的转储文件
. sqlt_snnnnn_import.sh—Unix版本的导入SQLT对象脚本
. sqlt_snnnnn_metadat.sql—setup.sql调用该脚本;创建测试用户和用户对象
. sqlt_snnnnn_purge.sql—从SQL档案库中删除对测试用例SQL的引用
. sqlt_snnnnn_readmet.txt—记录特定的测试用例，包含导出和导入SQLT档案库信息的简单命令，SQLTCOMPARE的使用，还原CBO统计信息和在快捷模式和客户模式下完成测试用例
. sqlt_snnnnn_restore.sql—导入CBO的统计信息到测试用例中
. sqlt_snnnnn_set_cbo_env.sql—设置测试用例的CBO环境
. sqlt_snnnnn_system_stats.sql—设置测试系统的系统统计信息
. tc.sql—运行测试sql并显示执行计划
. tc_pkg.sql—对一些小的测试用例文件进行打包并生成tc.zip文件
. xpress.sh—xpress.sql的Unix版本。用来构建整个测试用例

. xpress.sql—这个脚本以快捷方式来构建整个测试用例

正如你所看到的一旦解压后在sqlt_s34879_tc目录中会生成许多文件。它们中的大部分会被xpress.sql和setup.sql脚本调用，因此我们不会详细讨论它们，
但有一些有趣的单独的功能在我们构建测试用例后来查看。

3.快速构建一个测试用例(XPRESS.sql)
首先我们创建一个目录来存储SQLTXTRACT报告文件。在这个目录中我创建一个TC目录并将测试用例zip文件放入TC目录。现在我们有了测试用例目录，解压测试用例文件来快速和简单的构建一个测试用户。记住你需要用SYS用户进行登录并执行这个操作。这是因为xpress.sql中的有些操作将会改变数据库环境。这种环境是不能与其它用户进行共享的。因此使用有警告的方式来构建一个测试用例。

首先我们将执行xpress.sql。这将在各个部分暂停并给你机会来检查步骤和任何错误。如果没有错误，那么正常情况你只需要按下回车键就会执行下一步操作。脚本中的这些步骤每一个都被突出的显示出来例如：

SQL> @xpress.sql
1/7 Press ENTER to create TC user and schema objects for statement_id 34879.

下面按级别列出了查看脚本的步骤。下面我们将查看这七步操作的详细信息：
1. 创建测试用户，用户对象（包含表和索引），用户名的形式为TCnnnnn。在步骤1中你被要求输入测试用户用户名的前缀。你在这时可以按回车键或者输入像DEV这样的前缀。在这一步的最后你应该检查是否存在任何无效对象。有效对象会被列出来
2. 任何SQL语句以前版本的SQL档案库信息会被清除
3. 使用导入工具SQL语句将被导入到SQL档案库中并且会还原系统环境。你将被要求输入SQLTXPLAIN用户的密码。执行这一步的就是因为你不应该在系统中运行快捷方式不能避免丢失的原因
4. 测试用户方案对象统计信息会被还原
5. 系统统计信息会被还原
6. 你被连接到测试用户方案并设置CBO环境
7. 测试用户方案环境被设置，SQL被执行并显示其执行计划

一旦你到达这个阶段，假设没有任何错误，你就可以自由的修改测试环境（记住在测试完成后这个系统就会被丢弃）。你可以根据提高你测试用例性能的要求进行修改，或者有时为了更好的理解发生的操作和执行计划你可能会对测试用例进行一些修改。下面我们将查看七步操作每一步的详细信息。我们将根据看到的示例输出并解释正在执行的操作。我们将通过这所有的步骤来构建一个能进行测试的测试环境。
1. 在步骤1中你被要求确认你想要创建的测试用户（在我的例子中是TC64661）和方案对象

如果你输入回车键来完成步骤1。在这个步骤中运行了sqlt_metadata.sql脚本。你被要求为测试用户输入一个前缀。通常的值为”_1”，但你可以输入回车键接受缺省值，不使用前缀。然后就会创建元数据对象，比如表和索引，还有其它约束，函数和包，视图或者任何其它的元数据。在这个步骤的最后将会显示对象的状态。它就座都为valid有效。这里是我的示例的一个截屏。

2/7 Press ENTER to purge statement_id 34879 from SQLT repository.

在我们例子中所有元数据对象都是有效的，并且我这里没有包，视图，函数，或过程。因此这里没有无效对象，我输入回车键开始执行步骤2.
2. 在步骤2中将运行sqlt_snnnnn_purge.sql脚本。它将清空任何与被分析SQL语句相关的SQLT档案库信息。在需要的时候重新加载一个测试用例是很常见的。这个脚本的输出类似如：

SQL> @@sqlt_s34879_purge.sql
SQL> REM Purges statement_id 34879 from local SQLT repository. Just execute "@sqlt_s34879_purge.sql" from sqlplus.
SQL> SPO sqlt_s34879_purge.log;

我们只是将对象统计信息导入到系统中的TC64661用户中因此它们是测试用户方案的统计信息。在这个过程的最后我们看到每一个对象的统计信息被成功导入并且要求我们处理步骤5。
5. 在步骤5中我们要删除已经存在的系统统计信息（我已经说了只有在系统中没有生产数据和其它用户时你才这么做）。然后用对系统统计信息设置新值。然后要求我们处理步骤6。

脚本sqlt_s34879_set_cbo_env.sql将设置CBO环境。它很重要你应该在执行它前查看其内容。

当你输入回车键时，所有的CBO环境设置将在系统级别进行。在我的例子中日志文件包含以下信息：

/*************************************************************************************/

注意我们是如何修改系统参数的。例如optimizer_dynamic_sampling被设置为0。这是不缺省值，这里日志文件中所记录的对隐含会话参数的设置：

SQL>
SQL> -- compute join cardinality using non-rounded input values
SQL> ALTER SESSION SET "_optimizer_new_join_card_computation" = TRUE;
Session altered.
SQL>
SQL> -- null-aware antijoin parameter

Session altered.
SQL>
SQL> -- Eliminates order bys from views before query transformation
SQL> ALTER SESSION SET "_optimizer_order_by_elimination_enabled" = TRUE;
Session altered.

注意前面例子中的隐含参数。我们甚至设置了_fix_control参数，在下面的例子中，fix_control参数控制着特定的bug修复(包含数据库的)是否启用还是禁用。这里给出了日志文件中fix control部分的信息（我们将在下一章中讨论fix control）。

SQL>

使用DML Error Logging来避免bulk insert故障
当使用带有子查询的insert语句来加载数据时如果出现错误.系统会终止该语句并回滚整个操作.这是非常消耗时间和资源的操作.如果insert这样的语句可以使用DML Error Logging功能来避免这种情况.

为了使用DML error logging功能需要增加一个子句来指定error logging表名来记录当DML操作所遇到的错误记录.当向insert
语句增加一个error logging子句时特定类型的错误将不会被终止和回滚语句.相反每一个错误记录会被记录到表中操作语句能继续执行.在操作完成后可以对错误记录执行修正操作.

DML error logging功能可以与insert,update,merge和delete语句一起使用.

为了使用DML error logging功能来插入数据
1.来创建一个error logging表
可以手工创建或者使用dbms_errlog包来自动创建.

2.执行一个包含error logging子句的insert语句:
.可以选择引用自己创建的error logging表.如果没有提供一个error logging表表名.数据库会使用一个缺省的error logging表.
缺省的error loggin表名为err$_后面紧接着是插入表名的前25个字符.

.可以选择包含一个标签(一个数字或者有括号的字符串)它将添加到错误日志中来帮助你识别哪个语句产生的错误.如果标签被忽略将使用null值

.可以选择包含reject limit子句
这个子句指示在insert语句终止和回滚之前可以遇到的错误的最大数量.可以指定为unlimited.缺省的reject limit为0,这意味着
在遇到第一个错误时会记录错误并回滚语句.对于并行操作reject limit应用到每一个并行服务器进程.

3.查询error logging表对于产生错误的行执行修正.

error logging表的格式
一个error logging表由两部分组成:
.描述错误的一组强制列.例如一个列包含了oracle的错误代码

.包含造成错误行数据的一组可选列.这些列名与执行插入操作的表中的列名相匹配.
error logging表中的这部分的列数可以是0,1或者多个直到与DML表中的列数相等.如果在error logging表中的列与DML表中的列
有相同的名字,那么违反插入操作的行记录中的相关数据会被写入这个error logging表中的列中.如果DML表中的列在error logging表中没有与之相关的列,那么这个列将不会记录.如果error logging表包含一个与DML表不相匹配的列那么这个列会被忽略.

因为类型转换错误是一种可能出现的错误类型,在error logging表中的可选列的数据类型必须是能捕获任何值而不会丢失数据或转换错误的数据类型.(如果可选日志列与DML表列有相同的数据类型,那么记录捕获问题数据时也会有相同的数据转换问题).数据库为了记录造成转换错误的数据的有用信息做出了最大努力.如果值不能通过派生得到,对于这个列会记录null值.插入errog logging表的一个错误会导致语句终止.

创建错误日志表
可以手工创建一个错误日志表或者使用pl/sql包来自动创建

使用dbms_errlog包可以自动创建一个错误日志表.create_error_log过程将创建一个有所有强制描述错误的列加上DML表中所有列
的一个错误日志表
​首先创建一个要存储数据的表test_emp

SQL> create table test_emp as select * from hr.employees where 1=2;

Table created.

SQL> alter table test_emp add primary key (employee_id);

Table altered.

先向test_temp表中插入一条记录因为让后面的插入操作产生违反主键约束的错误

SQL> insert into test_emp select * from hr.employees where rownum<2;

1 row created.

SQL> commit;

创建错误日志表

SQL> execute dbms_errlog.create_error_log('TEST_EMP','ERR_EMP');

PL/SQL procedure successfully completed.

从err_emp表中的记录可以看到不能插入test_emp的记录的错误信息是因为违反主键约束.

error logging的限制和警告
当执行DML操作时出现以下错误时oracle数据库会进行记录:
.列的值太长
.违反约束(not null,unique,referential,check)
.在触发器执行时触发的错误
.在子查询列与DML表相关列之间类型转换的错误
.分区映射错误
.特定的merge操作错误(ora-30926:Unable to get a stable set of rows for MERGE operation)

有一些错误不会记录且会造成DML操作终止和回滚.

客户的oracle数据库启动报错,操作linux,oracle 11g由于将lock_sga参数设置为true当重启数据库时报错ORA-27102: out of memory

SQL> startup nomount
ORA-27102: out of memory
Linux-x86_64 Error: 12: Cannot allocate memory

原因是因为操作参数没有设置为允许sga所指定大小的内存可以被锁定

最消耗共享池内存和存在高版本游标的是insert语句. 通过version_rpt3_23.sql脚本查看insert语句不能共享的原因是绑定变量丢失.

INSERT INTO KCD4 (AAC001, AAE030, AAE031, AAE117, AAE208, AAE209, AAZ107, AAZ208, AAZ216, AAZ217, AJE001, AKA030, AKA130, AKC228, AKC291, AKE029, AKE030, AKE032, AKE033, AKE034, AKE035, AKE036, AKE037, AKE038, AKE039, AKE040, AKE041, AKE042, AKE043, AKE044, AKE045, AKE046, AKE047, AKE049, AKE050, AKE051, ALC113, ALC136, ALE001, AME001, AKB081, AKC264, AAA027, AKE025, AKE009, AKE011, AKE012, AKE016, AKE018, AKE019, AKE026, AKE071, AKE072, AKE073, AKE074, AKE075, AKE076, AKE077, AKE078, AKE079, PRSENO, BKA001, AAE100, BKA003, AKE083, AKE084, AKE085, AKE086, AKE087, AKE088, AKE089, AKE090/*AKE080*/) VALUES(:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15, :16, :17, :18, :19, :20, :21, :22, :23, :24, :25, :26, :27, :28, :29, :30, :31, :32, :33, :34, :35, :36, :37, :38, :39, :40, :41, :42, :43, :44, :45, :46, :47, :48, :49, :50, :51, :52, :53, :54, :55, :56, :57, :58, :59, :60, :61, :62, :63, :64, :65, :66, :67, :68, :69, :70, :71, :72)

上面的语句的形式为
Insert into table(column1, column2, column72) values (:1, :2, :3, …:72)
这种插入语句是通过对象映射工具生成的.其中values子句中存在许多的null值.对于insert into 或者select into可以考虑不要使用绑定变量.对于一个字段很多的表，在insert的时候不要把值为null, 字段允许为空的所有字段都体现在insert语句中.因为当字段为null时,在解析时是没办法判断类型和长度的,当这样的字段太多时sql语句是没办法共享的.对于这种问题修改insert语句的写法是最佳的解决办法.上面的awr报告中的共享池内存在自动管理模式下增长到了9808M,buffer cache为6,528M.可以考虑手工来指定shared pool和buffer cache的大小.

连接因式分解（Join Factorization）是优化器处理带union all的目标SQL的一种优化手段，它是指优化器在处理以union all连接的目标SQL的各个分支时，不再原封不动地分别重复执行每个分支，而是会把各个分支中公共的部分提出来作为一个单独的结果集，然后再和原union all中剩下的部分做表连接。连接因式分解在Oracle 11gr2中才被引入，它的好处是显而易见的。如果不把union all中公共的部分提出来，则意味着这些公共部分中所包含的表会在union all的各个分支中被重复访问；而连接因式分解则能够在最大程度上避免这种重复访问现象的产生，当union all的公共部分所包含的表的数据量很大时，减少一次对大表的重复访问，那也意味着执行效率的巨大提升。

我们来看一个连接因式分解的实例。先来看用union all连接的例子：

select t2.prod_id as prod_id
from sales t2,customers t3
where t2.cust_id=t3.cust_id
and t3.cust_gender='MALE'
union all
select t2.prod_id as prod_id
from sales t2,customers t3
where t2.cust_id=t3.cust_id
and t3.cust_gender='FEMALE';

范例SQL的union all的各个分支中仅仅是针对表customers的列cust_gender的限制条件不一样，剩下的部分都是一模一样的，这也意味着表sales就是范例SQL的公共部分。如果这里Oracle不把sales表提出来，不对此SQL做连接因式分解，那就意味着要重复访问表sales两次。

来验证一下。先在Oracle 10gr2中执行范例SQL：

SQL> select t2.prod_id as prod_id
  2  from sales t2,customers t3
  3  where t2.cust_id=t3.cust_id
  4  and t3.cust_gender='MALE'
  5  union all
  6  select t2.prod_id as prod_id
  7  from sales t2,customers t3
  8  where t2.cust_id=t3.cust_id
  9  and t3.cust_gender='FEMALE';

从上述显示内容可以看出，这里Oracle就是原封不动地分别重复执行了范例SQL的每个分支，最后对每个分支的执行结果做了一个union all。注意Id=9和Id=17的执行步骤均为“TABLE ACCESS FULL | SALES”，这说明Oracle对数据量接近100万的表sales重复执行了两次全表扫描，这是不好的。

在Oracle 11gr2中再执行一次范例SQL,看看Oracle 11gr2会如何处理该SQL：

SQL> select t2.prod_id as prod_id

  3  where t2.cust_id=t3.cust_id

从上述显示内容可以看出，对表sales的全表扫描只在Id=15的执行步骤处出现了一次，这说明同样的SQL在Oracle 11gR2中只需要全表扫描sales一次，另外，Id=2的执行步骤的Operation列的值是“VIEW”，对应的 Name列的值是“VW_JF_SET$0F531EB5”（这里VW_JF_SET$0F531EB5中的关键字是JF是Join Factorization的缩写），同时Id=1的执行步骤的Operation列的值是”HASH JOIN”。种种迹象都说明Oracle已经把范例SQL中union all的公共部分表sales提了出来，然后和union all 剩下的部分所形成的内嵌视图VW_JF_SET$0F531EB5做了一个哈希连接，即Oracle已经对范例SQL做了连接因式分解。

连接因式分解除了能够避免对公共部分中所包含的表做重复访问之外，还可以提供更多的执行路径给优化器做选择，这就增加了走出更高效执行计划的可能性。

创建一个视图view_jf，其视图定义SQL语句就是范例SQL：

SQL> create or replace view view_jf as
  2  select t2.prod_id as prod_id
  3  from sales t2,customers t3
  4  where t2.cust_id=t3.cust_id
  5  and t3.cust_gender='MALE'
  6  union all
  7  select t2.prod_id as prod_id
  8  from sales t2,customers t3
  9  where t2.cust_id=t3.cust_id
 10  and t3.cust_gender='FEMALE';

View created.

然后我们来看如下形式的SQL1：
select t1.prod_id,t1.prod_name
from products t1,view_jf
where t1.prod_id=view_jf.prod_id
and t1.prod_list_price>1000;

在范例SQL1中，表products和视图view_jf做了表连接，而view_jf又是表sales和customers做表连接且做union all的视图。因为view_jf中包含了集合运算符union all，所以Oracle不能对它做视图合并，即Oracle必须将view_jf的定义SQL语句当作一个整体来单独执行，这也就意味着sales必须和customers做表连接，然后才能和表products再做表连接。

在Oracle10gr2中执行范例SQL1：

SQL> select t1.prod_id,t1.prod_name
  2  from products t1,view_jf
  3  where t1.prod_id=view_jf.prod_id
  4  and t1.prod_list_price>1000;

注意到Id=3的执行步骤的Operation列的值为“VIEW”，对应Name列的值为“VIEW_JF”，这说明Oracle确实没有对范例SQL1中的视图VIEW_JF做视图合并，即Oracle现在还是将VIEW_JF的定义SQL语句当作一个整体来单独执行，所以此时表sales和customers分别做了两次哈希连接，然后Oracle将这两次哈希连接的连接结果做了union all合并后，才和视图VIEW_JF外部的表products再做一次哈希连接。

在Oracle 11gr2中再执行一次范例SQL1,看看在Oracle 11gr2中会如何处理该SQL：

SQL> select t1.prod_id,t1.prod_name
  2  from products t1,view_jf
  3  where t1.prod_id=view_jf.prod_id
  4  and t1.prod_list_price>1000;

注意到Id=2的执行步骤的Operation列的值是“VIEW”，其对应的Name列的值是“VW_JF_SET$7C24F767”，和范例SQL一样，
这说明Oracle已经把视图view_jf的定义SQL语句中union all的公共部分表sales提了出来，然后用union all剩下的部分形成了
一个内嵌视图VW_JF_SET$7C24F767，即Oracle已经对范例SQL1做了连接因式分解。

有一条SQL在测试环境中能做连接因式分解，测试环境与生产环境完全全相同，同事说在生产环境中发现不能进行连接因式分解，说帮忙看看原因是因为生产环境中与该SQL相关的三张表原来的数据被清空了，而新导入的数据没有收集统计信息赞成的。下面来模拟测试一下这个问题。

下面的SQL在表sales,customers没有统计信息时不能进行连接因式分解

SQL> select t2.prod_id as prod_id
  2  from sales t2,customers t3
  3  where t2.cust_id=t3.cust_id
  4  and t3.cust_gender='MALE'

在Oracle 11gr2及其后续的版本中，即使由于在视图定义SQL语句中包含了集合运算符union all而导致 Oracle不能对其做视图合并，Oracle也不一定会把该视图的定义SQL语句当作一个整体来单独执行，因为此时Oracle还可能会对其做连接因式分解。这里需要注意的是，Oracle对包含union all的目标SQL做连接因式分解的前提条件是，连接因式分解后的等价改写SQL和原SQL在语义上完全等价，如果不能满足这一点，那么Oracle就不会做连接因式分解。

朋友和我说发现了oracle union操作的一个bug,他的查询语句如下:

SQL> select sum(a1) a1,sum(a2) a2
  2  from (
  3  select 1 a1,0 a2 from dual
  4  union
  5  select 0 a2, 1 a1 from dual
  6  )
  7  ;

        A1         A2
---------- ----------
         1          1


SQL> select 1 a1,0 a2 from dual
  2  union
  3  select 0 a2, 1 a1 from dual
  4  ;

        A1         A2
---------- ----------
         0          1
         1          0

说结果出错了，应该a2为0,他说别名为 a2的值其实是0,说union不是按别名来进行区别的，一开始我还没反应过来。后面想了一下，union的意思是用来合并两条查询的结果并去重，在oracle关于sql的文档中是说union集合操作中的两个查询中的列的类型和个数要相同。例如将上面两个查询别名为a2的值从0改成’0’再执行union操作就会报错:

SQL> select 1 a1,'0' a2 from dual
  2  union
  3  select '0' a2, 1 a1 from dual
  4  ;

select 1 a1,'0' a2 from dual
union
select '0' a2, 1 a1 from dual

ORA-01790: 表达式必须具有与对应表达式相同的数据类型

从而说明了union其实是按列出现的顺序进行合并的，并不是按别名.对union的意思理解不对危害很大，从上面的列来说他本来的意思是a2应该为0,但因为他的顺序写错了结果变成了1。这种危害太大了，如果这些数字是钱本来应该为0的，结果因为查询中列的顺序写错了，就会造成巨大的损失。而朋友的系统就是这么巧就是money，且软件运行了有些年头了。
