从查询中获取结果时，列的顺序错误

var max_sync_time = max_sync_time_result.getColumnValue(1);  
var new_watermark_value = (max_sync_time_result.getColumnValue(2)); 

应该是

var max_sync_time = max_sync_time_result.getColumnValue(2);  
var new_watermark_value = (max_sync_time_result.getColumnValue(1)); 

更新

var update_watermark_sql_command = `update APPLICATION_CONTROL  
                                    set watermark_value =  :1 
                                    WHERE TABLE_NAME = 'TEST1'; `

snowflake.execute ({ sqlText: update_watermark_sql_command, binds: [new_watermark_value.toISOString()] });
