没有函数匹配给定的名称和参数类型。您可能需要添加显式类型转换

Question

我在Postgres中创建了如下表格。

CREATE TABLE rv_data_bkt_country_m
(
 interval_start timestamp without time zone NOT NULL,
 creative_id integer NOT NULL,
 zone_id integer NOT NULL,
 country character(3) NOT NULL DEFAULT ''::bpchar,
 city character(50) NOT NULL DEFAULT ''::bpchar,
 count integer NOT NULL DEFAULT 0,
 CONSTRAINT rv_data_bkt_country_m_pkey PRIMARY KEY (interval_start, creative_id, zone_id, country, city)
)

使用

插入时

SELECT bucket_update_rv_data_bkt_country_m('2018-03-14 08:00:00,1,1,'IN','',1)" 

此查询。它显示以下错误

ERROR:  function bucket_update_rv_data_bkt_country_m(unknown, integer, integer, unknown, unknown, integer) does not exist
LINE 1: SELECT bucket_update_rv_data_bkt_country_m('2018-03-14 08:00...
              ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

如何解决此错误？
