Question

我有两个表permit_table，其中包含columns builder和permit_number weekly_table with columns applicant和permit_number。现在，如果来自permit_table的构建器列中有任何更新，我需要使用'旧申请人值+新构建者值'更新weekly_table的申请人列，前提是permit_table中更新的构建者值的许可证编号应与任何许可证编号相匹配。 weekly_table。我尝试过以下触发器和功能

ESC[36mverboseESC[39m: REQUEST for [PUT] /parse/classes/_Installation   /zKIp8LLOWr: {
                                                                              "GCMSenderId":"diMV6Hm3j07dbqVPEsZRgqNzDo3YvA5zNdUmtO6Q4ka5ijRyyIRHiWCWOBVBDA22OIls-4bO06kxDPuOKFwJUZuMD3Xt41WuKUoOJwBlW7cKdqv9llj7Me0uiWFLWDwS7V",

触发器是

CREATE OR REPLACE FUNCTION edmonton.automated_builder_update_trigger_manual()
RETURNS trigger AS
$BODY$
DECLARE
    e record;
BEGIN

EXECUTE format('Update weekly_table as a
set applicant = old.applicant||new.builder where old.permit_number = 
a.permit_number');


RETURN NULL;
END;
$BODY$
 LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION edmonton.automated_builder_update_trigger_manual()
OWNER TO postgres;

收到错误'错过表'old'的FROm CLAUSE条目。

Answer 1

EXECUTE format('Update weekly_table as a
set applicant = old.applicant||new.builder where old.permit_number = 
a.permit_number');

尝试改为：

EXECUTE format('Update weekly_table as a
set applicant = ($1).applicant||($2).builder where ($1).permit_number  = 
a.permit_number') using old,new;

在postgresql中更新触发器后，将值从一个表更新到另一个表
