今天刚好有空,就分析下 金蝶BOS 7.5 SQL语句生成 方式.(分析环境 Oracle 11.0.2 , 金蝶BOS 7.5.0)
1 操作思路
思路是这样的，在开发环境触发SQL操作，然后在数据库中查出最近执行的SQL，对其分析．
数据库里使用SQL语句：
--这里只查询JDBC操作的SQL语句
SELECT t.sql_id,
t.sql_text,
t.sql_fulltext,
to_char(t.last_active_time, 'yyyy-mm-dd HH24:mi:ss')
FROM v$sql t
WHERE t.last_active_time > SYSDATE - 0.0005
AND t.module = 'JDBC Thin Client'
ORDER BY t.last_active_time DESC；
--根据SQL＿ID获取执行时参数值
SELECT child_number,
NAME,
position,
datatype_string,
value_string,
last_captured
FROM v$sql_bind_capture
WHERE sql_id = '8du5umjut76wc'
ORDER BY child_number,
position;来获取最近一分钟内执行的SQL．
2 操作数据
实体找了带有一个分录的基础资料,数据共5条. ( 实体 package-> CT_BAS_PACKAGE,分录 E1 ->CT_BAS_PACKAGEE1 ).
3 操作过程
3.1 KSQL
为了操作直观,这里不使用 EntityViewInfo 操作,而是直接从 KSQL 下手,操作代码类似:
IPackage ipackage = PackageFactory.getRemoteInstance();
package.getPackageCollection("select * where number='BZ0001'");//select * where number='BZ0001' 为KSQL分析结果:
--KSQL：select * where number='BZ0001'
SELECT "T0"."FID" "ID",
"T0"."FCREATORID" "T1.ID",
"T0"."FCREATETIME" "CREATETIME",
"T0"."FLASTUPDATEUSERID" "T2.ID",
"T0"."FLASTUPDATETIME" "LASTUPDATETIME",
"T0"."FCONTROLUNITID" "T3.ID",
"T0"."FNAME_L2" "NAME",
"T0"."FNAME_L1" "NAME_L1",
"T0"."FNAME_L2" "NAME_L2",
"T0"."FNAME_L3" "NAME_L3",
"T0"."FNUMBER" "NUMBER",
"T0"."FDESCRIPTION_L2" "DESCRIPTION",
"T0"."FDESCRIPTION_L1" "DESCRIPTION_L1",
"T0"."FDESCRIPTION_L2" "DESCRIPTION_L2",
"T0"."FDESCRIPTION_L3" "DESCRIPTION_L3",
"T0"."FSIMPLENAME" "SIMPLENAME",
"T0"."CFSTATE" "STATE"
FROM "CT_BAS_PACKAGE" "T0"
WHERE "T0"."FNUMBER" = :1;
--查询分录ID
SELECT "T0"."FID" "ID",
"T0"."FPARENTID" "T1.ID"
FROM "CT_BAS_PACKAGEE1" "T0"
INNER JOIN "CT_BAS_PACKAGE" "T1" ON "T0"."FPARENTID" = "T1"."FID"
WHERE "T1"."FNUMBER" = :1
ORDER BY "T1.ID" ASC,
"T0"."FSEQ" ASC;
--总结:如果不指定,会查询主表数据,加分录数据中的 fid 字段
--KSQL：select number where number='BZ0001'
SELECT "T0"."FID" "ID",
"T0"."FNUMBER" "NUMBER"
FROM "CT_BAS_PACKAGE" "T0"
WHERE "T0"."FNUMBER" = :1;
--
SELECT "T0"."FID" "ID",
"T0"."FPARENTID" "T1.ID"
FROM "CT_BAS_PACKAGEE1" "T0"
INNER JOIN "CT_BAS_PACKAGE" "T1" ON "T0"."FPARENTID" = "T1"."FID"
WHERE "T1"."FNUMBER" = :1
ORDER BY "T1.ID" ASC,
"T0"."FSEQ" ASC;
--总结:即使在主表中指定了主数据的查询字段,仍然会查询分录 fid ,真是让人失望
--KSQL：select E1.id where number='BZ0001'
SELECT "T0"."FID" "ID" FROM "CT_BAS_PACKAGE" "T0" WHERE "T0"."FNUMBER" = :1;
--
SELECT "T0"."FID" "ID",
"T0"."FPARENTID" "T1.ID"
FROM "CT_BAS_PACKAGEE1" "T0"
INNER JOIN "CT_BAS_PACKAGE" "T1" ON "T0"."FPARENTID" = "T1"."FID"
WHERE "T1"."FNUMBER" = :1
ORDER BY "T1.ID" ASC,
"T0"."FSEQ" ASC;
--总结:这里也是很让人失望,指定分录中字段查询,仍会查询两次,BOS对于ID真是有很深的执念啊
--KSQL：select E1.* where number='BZ0001'
SELECT "T0"."FID" "ID" FROM "CT_BAS_PACKAGE" "T0" WHERE "T0"."FNUMBER" = :1;
--
SELECT "T0"."FID" "ID",
"T0"."FSEQ" "SEQ",
"T0"."FPARENTID" "T1.ID",
"T0"."CFNAME" "NAME",
"T0"."CFREMARK" "REMARK",
"T0"."CFWIDTH" "WIDTH",
"T0"."CFHIGTH" "HIGTH",
"T0"."CFLONGNUM" "LONGNUM"
FROM "CT_BAS_PACKAGEE1" "T0"
INNER JOIN "CT_BAS_PACKAGE" "T1" ON "T0"."FPARENTID" = "T1"."FID"
WHERE "T1"."FNUMBER" = :1
ORDER BY "T1.ID" ASC,
"T0"."FSEQ" ASC;
--总结:同上
--KSQL：select E1 where number='BZ0001'
SELECT "T0"."FID" "ID" FROM "CT_BAS_PACKAGE" "T0" WHERE "T0"."FNUMBER" = :1;
--
SELECT "T0"."FID" "ID",
"T0"."FPARENTID" "T1.ID"
FROM "CT_BAS_PACKAGEE1" "T0"
INNER JOIN "CT_BAS_PACKAGE" "T1" ON "T0"."FPARENTID" = "T1"."FID"
WHERE "T1"."FNUMBER" = :1
ORDER BY "T1.ID" ASC,
"T0"."FSEQ" ASC;
--总结: 这里分录 E1 转换成 E1.fid ,而不是 E1.* ,这个做得好.3.2 exists 操作
IPackage ipackage = PackageFactory.getRemoteInstance();
FilterInfo filter=new FilterInfo();
filter.appendFilterItem("number", "BZ0001");
ipackage.exists(filter);数据库SQL
SELECT "T0"."FID"
FROM "CT_BAS_PACKAGE" "T0"
WHERE "T0"."FNUMBER" = :1
AND rownum <= 1;这个让人还算满意.
3.3 Query
大家都知道在EAS 里面 list 界面使用的是 Query的数据,用于筛选和排序.
Query里显示的SQL
SELECT "PACKAGE".FID AS "ID",
"PACKAGE".FNumber AS "NUMBER",
"PACKAGE".FName_l2 AS "NAME",
"PACKAGE".FDescription_l2 AS "DESCRIPTION",
"PACKAGE".FLastUpdateTime AS "LASTUPDATETIME",
"LASTUPDATEUSER".FName_l2 AS "LASTUPDATEUSER.NAME",
"PACKAGE".FCreateTime AS "CREATETIME",
"CREATOR".FName_l2 AS "CREATOR.NAME",
"PACKAGE".CFState AS "STATE"
FROM ct_bas_package AS "PACKAGE"
INNER JOIN t_pm_user AS "CREATOR" ON "PACKAGE".FCreatorID = "CREATOR".FID
INNER JOIN t_pm_user AS "LASTUPDATEUSER" ON "PACKAGE".FLastUpdateUserID =
"LASTUPDATEUSER".FID
WHERE "PACKAGE".CFState = 1
ORDER BY "LASTUPDATETIME" ASC,
"NUMBER" ASC;实际执行的SQL:
--创建表,存入查询数据(这张表,晚点会被删掉),只有 ksql_seq, id 两列,用于保存顺序和ID
INSERT INTO vtzoggntt1c6bxfd8u1mbc4q020
(ksql_seq, id)
SELECT rownum,
TMP_SUBSELECT_ALIAS."ID"
FROM (SELECT *

INNER JOIN t_pm_user "CREATOR" ON "PACKAGE".FCreatorID =

INNER JOIN t_pm_user "LASTUPDATEUSER" ON "PACKAGE".FLastUpdateUserID =
"LASTUPDATEUSER".FID
WHERE ("PACKAGE".CFState = :1 AND

"PACKAGE".FControlUnitID = :4))
ORDER BY "LASTUPDATETIME" ASC,
"NUMBER" ASC)
WHERE rownum <= 10000) tmp_subselect_alias
WHERE rownum <= 10000;
--查询数据总数
SELECT *
FROM (SELECT ksql_seq FROM vtzoggntt1c6bxfd8u1mbc4q020 ORDER BY ksql_seq DESC)
WHERE rownum <= 1;
--查询前50条数据( 这个50 从哪里来的,不清楚)
SELECT *
FROM vtzoggntt1c6bxfd8u1mbc4q020
WHERE ((ksql_seq >= :1) AND (ksql_seq <= :2))
ORDER BY ksql_seq ASC;
--这里只有5条数据,为了方便看,我把参数加到SQL里了,可以看出,根据上面的查询结果,这里分两种情况,分别是ID和....真是任性

ORDER BY "LASTUPDATETIME" ASC,
"NUMBER" ASC;总之,我认为EAS BOS ７.５ 在SQL语句的生成方式上,相对 Hibernate之流相甚远!!!!完全没有效率可言.特别是创表存储数据,稍后删除的作法,更是让人不可思议.
