oracle调用子存储过程+游标循环实例
一,有子节点的部门的子节点的排序,调用子存储过程
CREATE OR REPLACE PROCEDURE "PRO_INIT_SORT" ASCURSOR cur_department_all IS select * from tbl_department;VAR_COUNT NUMBER ;VAR_OUT_COUNT NUMBER := 0;BEGIN FOR department_row IN cur_department_all LOOP SELECT COUNT(1) INTO VAR_COUNT FROM tbl_department WHERE unit_id = department_row.unit_id AND department_supercode = department_row.department_code ; --上述查询的是有所有的子节点的部门 IF VAR_COUNT != 0 THEN --dbms_output.put_line(department_row.unit_id||‘-‘||department_row.department_code||‘-‘||var_count); PRO_INIT_DEPARTMENT_SORT(department_row.unit_id , department_row.department_id) ; END IF ; VAR_OUT_COUNT := VAR_OUT_COUNT + 1 ; END LOOP ; DBMS_OUTPUT.PUT_LINE(‘总数:‘||VAR_OUT_COUNT);END PRO_INIT_SORT ;
CREATE OR REPLACE PROCEDURE "PRO_INIT_DEPARTMENT_SORT"( UNIT_ID IN NUMBER , SUPER_CODE IN NUMBER )-- 初始化TBL_DEPARTMENT表的DEPARTMENT_SORT字段 以同DEPARTMENT_SUPERCODE方式查询使用rownum值更新DEPARTMENT_SORT字段AS -- CURSOR cur_department IS SELECT * FROM tbl_department where unit_id = TARGET_UNIT_ID and department_supercode = TARGET_SUPERCODE ORDER BY department_sort ASC;CURSOR cur_department IS SELECT rownum rn , d.* FROM tbl_department d where unit_id = UNIT_ID and department_supercode = SUPER_CODE;BEGIN FOR department_row IN cur_department LOOP update tbl_department set department_sort = department_row.rn where department_id = department_row.department_id ; -- NULL ; END LOOP ;-- NULL;END PRO_INIT_DEPARTMENT_SORT;
注意:COUNT(1)和COUNT(*)
在数据记录都不为空的时候查询出来结果上没有差别的.
但当COUNT(1)查询的那列有空的时候空的是要被去掉的不记入统计中.这样查询出来的结果是不一样的.
二,没有子节点的排序
CREATE OR REPLACE PROCEDURE "INT_SORT_N" ASP_OUT NUMBER;P_COUNT NUMBER:=0;CURSOR CUR_DEPARTMENT IS SELECT T.UNIT_ID FROM TBL_DEPARTMENT T GROUP BY T.UNIT_ID ORDER BY T.UNIT_ID;BEGIN FOR DEP_ROW IN CUR_DEPARTMENT LOOP SELECT COUNT(1) INTO P_OUT FROM TBL_DEPARTMENT T WHERE T.UNIT_ID = DEP_ROW.UNIT_ID AND T.DEPARTMENT_SUPERCODE = 0; DBMS_OUTPUT.put_line(‘UID--‘||DEP_ROW.UNIT_ID||‘--部门--‘||P_OUT); INT_DEPARMENT_SORT(DEP_ROW.UNIT_ID); P_COUNT := P_COUNT + 1; END LOOP; DBMS_OUTPUT.put_line(‘总数:‘||P_COUNT);END;
create or replace procedure INT_DEPARMENT_SORT(UNIT_ID2 IN NUMBER) ASCURSOR DEPARTMENT_ALL IS SELECT rownum rn,T.* FROM TBL_DEPARTMENT T WHERE T.UNIT_ID = UNIT_ID2 AND T.DEPARTMENT_SUPERCODE = 0 ORDER BY T.DEPARTMENT_ID;begin FOR DEP_ROW IN DEPARTMENT_ALL LOOP --dbms_output.put_line(‘---‘||UNIT_ID2); UPDATE TBL_DEPARTMENT T SET T.DEPARTMENT_SORT = DEP_ROW.RN WHERE T.DEPARTMENT_ID = DEP_ROW.DEPARTMENT_ID; END LOOP; end INT_DEPARMENT_SORT;
