无法在雪花程序中转换日期变量

Question

我在将日期记录传递到变量时遇到错误。

想要将记录转换为日期格式 'YYYY-MM-DD' 而不是 'Feb 20 2022 HH:MM:SS' 格式。

javascript有日期转换方法吗？

CREATE OR REPLACE PROCEDURE sp_ADDWORKDAYS_CUTOFF_PP(SRC_DB STRING, SRC_SCHEMA STRING)
RETURNS varchar
LANGUAGE JAVASCRIPT
EXECUTE AS CALLER
AS
$$
  
  var D_STARTDATE = '';
  var D_WORKDAYS = '';
  var seq_query = `SELECT "DELIV_CR_DT" AS D_STARTDATE,DERIVED_COL AS D_WORKDAYS  FROM `+SRC_DB+`.`+SRC_SCHEMA+`.v_v_testing`;
    var seq_stmt = snowflake.createStatement({ sqlText: seq_query});
    var seq_result = seq_stmt.execute(); 
    while (seq_result.next()){
    
    var STARTDATE = seq_result.getColumnValue(1);
    var WORKDAYS = seq_result.getColumnValue(2);
    var sub_call_query = `CALL `+SRC_DB+`.`+SRC_SCHEMA+`.sp_OTD_ADDWORKDAYS(`+STARTDATE+`,`+WORKDAYS+`,'01')`;
    var sub_call_stmt = snowflake.createStatement({ sqlText: sub_call_query ,binds: [STARTDATE.toISOString(),WORKDAYS] });
    var sub_call_result = sub_call_stmt.execute(); 
    sub_call_stmt.next();
    var return_value = sub_call_result.getColumnValue(1);
}
  $$
;

错误： SQL编译错误：位置 52 处的语法错误行 1 意外 'Feb'。在Statement.execute，第14行位置40（第36行）

您可以尝试在您的日期转换逻辑中包含这样的内容 -

使用Java-script程序-

CREATE OR REPLACE PROCEDURE "GETJOBS"(SRC_DB STRING, SRC_SCHEMA STRING)
RETURNS varchar
LANGUAGE JAVASCRIPT
EXECUTE AS caller
AS
$$

  var D_STARTDATE = '';
  var D_WORKDAYS = '';
  var seq_query = `SELECT to_char(to_timestamp('Feb 20 2022 10:10:10','Mon DD YYYY HH24:MI:SS'), 'YYYY-MM-DD') AS D_STARTDATE`;
    var seq_stmt = snowflake.createStatement({ sqlText: seq_query});
    var seq_result = seq_stmt.execute();
    seq_result.next();
    return seq_result.getColumnValue(1);

$$
;

程序调用-

call getjobs('a','b');

GETJOBS
2022-02-20

使用 UDF -

create or replace function fn_getjobs(dt string)
returns string as
$$
select to_char(to_timestamp(dt,'Mon DD YYYY HH24:MI:SS'), 'YYYY-MM-DD') as return_dt
$$
;

函数调用

select fn_getjobs('Feb 20 2022 10:10:10') as dt;

DT
2022-02-20
