大家好,我有 2 个表 dcrhd(保存当前数据)和 dcrhd_arc(保存历史数据),我创建了一个函数来从这些表中获取一些数据。但是这个函数只满足我的一半要求(它检查来自 dcrhd 的数据仅限表)我将在这里分享我的功能..
CREATE OR REPLACE FUNCTION dcr_report( --fin_year_flag,
finid integer, prdid integer, comp_cd CHARACTER varying, divid integer, fsid integer) RETURNS refcursor LANGUAGE 'plpgsql' AS $BODY$
DECLARE
ref refcursor;
BEGIN
open ref for SELECT hd.report_no,
hd.dcr_date,
coalesce(pr2.para_descr,' ') work_type,
coalesce(pr1.para_descr,' ') hq_type,
coalesce(rm.route_name,' ') route_name,
coalesce(hd.doctor_visits,0) doctor_visits,
coalesce(hd.stockist_visits,0) stockist_visits,
coalesce(hd.retailer_visits,0) retailer_visits,
hd.dcr_id,
fm.fs_name,
hd.fstaff_id,
CASE hd.status
WHEN 'A' THEN 'APPROVED'
WHEN 'D' THEN 'DISCARDED'
WHEN 'F' THEN 'FORWARDED'
WHEN 'E' THEN 'DRAFT'
END
status,
zsm.fs_name report1,
rsm.fs_name report2,
fm.geog_lvl1_hq,
fm.level_code,
coalesce(pm.para_descr,'SELF') joint_work,
fm.fs_code,
fm.emp_code,
coalesce(hd.doc_other,0) doc_other
FROM dcrhd hd
LEFT OUTER JOIN parameters pm ON hd.jfw = pm.para_code AND pm.para_type = 'JFW'
LEFT OUTER JOIN route_master rm ON rm.fstaff_id = hd.fstaff_id AND rm.route_id = hd.route_id AND rm.company_cd
= comp_cd
LEFT OUTER JOIN parameters pr1 ON pr1.para_code = hd.hq_exhq AND pr1.para_type = 'HQ_',
parameters pr2,
field_master fm,
field_master zsm,
field_master rsm
WHERE hd.period_id = prdid AND hd.fin_year_id = finid AND hd.fstaff_id = fm.fs_id AND fm.mgr_level4 =
zsm.fs_id AND fm.mgr_level3 = rsm.fs_id AND fm.fs_id =
CASE
WHEN fsid = 0 THEN fm.fs_id
ELSE fsid
END
AND fm.div_id =
CASE
WHEN divid = 0 THEN fm.div_id
ELSE divid
END
AND fm.fs_id = hd.fstaff_id AND fm.level_code = '005' AND pr2.para_code = hd.work_type AND pr2.
para_type = 'WTP' AND hd.company = comp_cd AND fm.company_cd = comp_cd
ORDER BY fm.fs_name,
dcr_date;
RETURN REF;
END;
$BODY$;
我的要求是我只想添加一个名为的新参数'fin_year_flag'
并相应地选择主表(例如,if fin_year_flag='current'
然后转到dcrhd
else gotodcrhd_arc
我可以实现这个吗???你们可以分享你的想法吗???还有其他的吗?完全满足我的要求的方法??我是 PostgreSQL 新手,在互联网上搜索了很多次,但找不到任何有用的东西。
