金蝶BOS 7.5 SQL語句生成分析
今天恰好有空,就分析下 金蝶BOS 7.5 SQL語句生成 方式.(分析環境 Oracle 11.0.2 , 金蝶BOS 7.5.0)java
1 操做思路sql
思路是這樣的，在開發環境觸發SQL操做，而後在數據庫中查出最近執行的SQL，對其分析．
數據庫
數據庫裏使用SQL語句：app
--這裏只查詢JDBC操做的SQL語句 SELECT t.sql_id, t.sql_text, t.sql_fulltext, to_char(t.last_active_time, 'yyyy-mm-dd HH24:mi:ss') FROM v$sql t WHERE t.last_active_time > SYSDATE - 0.0005 AND t.module = 'JDBC Thin Client' ORDER BY t.last_active_time DESC； --根據SQL＿ID獲取執行時參數值 SELECT child_number, NAME, position, datatype_string, value_string, last_captured FROM v$sql_bind_capture WHERE sql_id = '8du5umjut76wc' ORDER BY child_number, position;
來獲取最近一分鐘內執行的SQL．spa
2 操做數據code
實體找了帶有一個分錄的基礎資料,數據共5條. ( 實體 package-> CT_BAS_PACKAGE,分錄 E1 ->CT_BAS_PACKAGEE1 ).排序
3 操做過程ip
3.1 KSQL開發
爲了操做直觀,這裏不使用 EntityViewInfo 操做,而是直接從 KSQL 下手,操做代碼相似:
get
IPackage ipackage = PackageFactory.getRemoteInstance();
package.getPackageCollection("select * where number='BZ0001'");//select * where number='BZ0001' 爲KSQL
分析結果:
--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; --查詢分錄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; --總結:若是不指定,會查詢主表數據,加分錄數據中的 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; --總結:即便在主表中指定了主數據的查詢字段,仍然會查詢分錄 fid ,真是讓人失望 --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; --總結:這裏也是很讓人失望,指定分錄中字段查詢,仍會查詢兩次,BOS對於ID真是有很深的執念啊 --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; --總結: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; --總結: 這裏分錄 E1 轉換成 E1.fid ,而不是 E1.* ,這個作得好.
3.2 exists 操做
IPackage ipackage = PackageFactory.getRemoteInstance();
FilterInfo filter=new FilterInfo();
filter.appendFilterItem("number", "BZ0001");
ipackage.exists(filter);
數據庫SQL
SELECT "T0"."FID" FROM "CT_BAS_PACKAGE" "T0" WHERE "T0"."FNUMBER" = :1 AND rownum <= 1;
這個讓人還算滿意.
3.3 Query
你們都知道在EAS 裏面 list 界面使用的是 Query的數據,用於篩選和排序.
Query裏顯示的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;
實際執行的SQL:
--建立表,存入查詢數據(這張表,晚點會被刪掉),只有 ksql_seq, id 兩列,用於保存順序和ID
INSERT INTO vtzoggntt1c6bxfd8u1mbc4q020
(ksql_seq, id)
SELECT rownum,
TMP_SUBSELECT_ALIAS."ID"
FROM (SELECT *
FROM (SELECT "PACKAGE".FID "ID",
"PACKAGE".FLastUpdateTime "LASTUPDATETIME",
"PACKAGE".FNumber "NUMBER"
FROM ct_bas_package "PACKAGE"
INNER JOIN t_pm_user "CREATOR" ON "PACKAGE".FCreatorID =
"CREATOR".FID
INNER JOIN t_pm_user "LASTUPDATEUSER" ON "PACKAGE".FLastUpdateUserID =
"LASTUPDATEUSER".FID
WHERE ("PACKAGE".CFState = :1 AND
("PACKAGE".FControlUnitID = :2 OR
"PACKAGE".FControlUnitID = :3 OR
"PACKAGE".FControlUnitID = :4))
ORDER BY "LASTUPDATETIME" ASC,
"NUMBER" ASC)
WHERE rownum <= 10000) tmp_subselect_alias
WHERE rownum <= 10000;
--查詢數據總數
SELECT *
FROM (SELECT ksql_seq FROM vtzoggntt1c6bxfd8u1mbc4q020 ORDER BY ksql_seq DESC)
WHERE rownum <= 1;
--查詢前50條數據( 這個50 從哪裏來的,不清楚)
SELECT *
FROM vtzoggntt1c6bxfd8u1mbc4q020
WHERE ((ksql_seq >= :1) AND (ksql_seq <= :2))
ORDER BY ksql_seq ASC;
--這裏只有5條數據,爲了方便看,我把參數加到SQL裏了,能夠看出,根據上面的查詢結果,這裏分兩種狀況,分別是ID和....真是任性
SELECT "PACKAGE".FID "ID",
"PACKAGE".FNumber "NUMBER",
"PACKAGE".FName_l2 "NAME",
"PACKAGE".FDescription_l2 "DESCRIPTION",
"PACKAGE".FLastUpdateTime "LASTUPDATETIME",
"LASTUPDATEUSER".FName_l2 "LASTUPDATEUSER.NAME",
"PACKAGE".FCreateTime "CREATETIME",

"PACKAGE".CFState "STATE"
FROM ct_bas_package "PACKAGE"

ORDER BY "LASTUPDATETIME" ASC,
"NUMBER" ASC;
總之,我認爲EAS BOS ７.５ 在SQL語句的生成方式上,相對 Hibernate之流相甚遠!!!!徹底沒有效率可言.特別是創表存儲數據,稍後刪除的做法,更是讓人難以想象.
