psycopg2 connect错误：一个函数不能传递100个以上的参数？

问题描述

我正在尝试将json对象作为参数传递给存储过程。我尝试了很多事情并最终解决了几个错误，但我陷入了这个错误“ psycopg2连接错误：不能将100个以上的参数传递给函数”，我尝试了json.dumps，它给了我this ..如果我是从具有相同输入的脚本执行可以正常工作。下面是我的存储过程。

CREATE OR REPLACE PROCEDURE public.insert_usr_details_in_all_tables (jsonobject json)
LANGUAGE 'plpgsql'
AS $BODY$
DECLARE
skill_s  Text[] := '{}';
    selectedSkill TEXT;
    edu TEXT;
    email TEXT;
    phone TEXT;
    usr_name TEXT;
    clg TEXT;
    lstEmployer TEXT;
    gendr TEXT;
    skill_row_count  INTEGER;
    usr_id INTEGER;
    skl_id INTEGER;
    intEmailExist INTEGER;
    expen DECIMAL;
BEGIN

    -- Getting name
    SELECT jsonobject->'Name' into usr_name;
    
    -- Getting education
    SELECT jsonobject->'Education' into edu;
    
    -- Getting phone number
    SELECT jsonobject->'phone_number' into phone;
    
    -- Getting experience
    SELECT (jsonobject->>'Exp')::DECIMAL INTO expen;
    
    --Getting college
    SELECT jsonobject->'College' into clg;
    
    
    -- Getting last employer
    SELECT jsonobject->'CurrentEmployer' into lstEmployer;
    
    --Getting gender
    SELECT jsonobject->'Gender' into gendr;
    
    -- Getting Email
    SELECT json_array_length(jsonobject->'Email') into intEmailExist;
    IF intEmailExist > 0 THEN 
        email:=array(SELECT json_array_elements_text(jsonobject->'Email'));
    END IF;
    
    -- Insert user details in 'Extractor_usr_details' table.
    INSERT INTO public."Extractor_usr_details"(name,phone_number,email,exp,education,college,"currentEmployer",gender)VALUES ( usr_name,phone,expen,edu,clg,lstEmployer,gendr) returning "id" into usr_id;
    
    skill_s := array(SELECT json_array_elements_text(jsonObject->'Skills'));
    FOREACH selectedSkill IN ARRAY skill_s LOOP
        INSERT INTO public."Extractor_skills" (skill) SELECT selectedSkill WHERE NOT EXISTS (SELECT id FROM public."Extractor_skills" WHERE skill = selectedSkill)RETURNING id into skl_id;
        INSERT INTO public."Extractor_usr_skills" (skill_id,user_id) SELECT skl_id,usr_id WHERE NOT EXISTS (SELECT id FROM public."Extractor_usr_skills" WHERE skill_id = skl_id AND user_id = usr_id);
    END LOOP;
    COMMIT;
END;
$BODY$;

这是我的代码，用于在python项目中调用存储过程

    try:
        # declare a new PostgreSQL connection object
        conn = connect(
            dbname="postgres",user="postgres",host="localhost",password="demo",port= '5432'
            # attempt to connect for 3 seconds then raise exception
        )
        cur = conn.cursor()
        cur.callproc('insert_usr_details_in_all_tables',json.dumps(jsonObject))


    except (Exception) as err:
        print("\npsycopg2 connect error:",err)
        conn = None
        cur = None
