在PostgreSQL中将表名作为参数传递

Question

我有下面的表和记录，我必须将表名（"LandXML_QCC_ParcelMarks"，"LandXML_QCC_ParcelInformation"）作为输入参数（tblparcelmarks，tblparcelinfo）传递给以下函数。 我如何在以下函数的查询中使用此表名参数。我试过了，但是没有用。

create table "LandXML_QCC_ParcelMarks"("DPID" TEXT,"From" TEXT,"Name" Text);

insert into "LandXML_QCC_ParcelMarks" values('1','ram','kumar');

create table "LandXML_QCC_ParcelInformation"("DPID" TEXT,"Pntref" Text);

insert into "LandXML_QCC_ParcelInformation" values('1','ram');

CREATE OR REPLACE FUNCTION public.getparcelnonparcelfinal(planid text, tblparcelmarks text, tblparcelinfo text)
RETURNS text AS
$BODY$
declare
    tblmark RECORD;
    parCount integer;
    parNonCount integer;
    totalParNonCount text;
    tblCou integer;
begin
    parCount = 0;
    parNonCount = 0;
    FOR tblmark IN (SELECT "From", "Name" FROM tblParcelMarks where "DPID" = planid) LOOP
        SELECT COUNT(*) into tblCou FROM tblParcelInfo where "DPID" = PlanID and ("Pntref" like '%' || tblMark."From" || ',' || CAST(tblMark."Name" As text) || '%' or "Pntref" like '%' || CAST(tblMark."Name" As text) || ',' || tblMark."From" || '%');
        IF tblCou > 0 THEN
            parCount = parCount + 1;
        ELSE
            parNonCount = parNonCount + 1;
        END IF;
    END LOOP;
    totalParNonCount = CAST(parCount As text) || ',' || CAST(parNonCount As text);
    return totalParNonCount;
end;
$BODY$
