where create_time >= to_timestamp('2023-01-01 00:00:00', 'yyyy-mm-dd hh24:MI:SS'); to_char 时间转字符串 select to_char(create_time, 'yyyy-mm-dd hh24:MI:SS') from t_user; 时间加减 -- 当前时间加一天 SELECT NOW()::TIMESTAMP + '1 day'; SELECT NOW() + INTERVAL '1 DAY...
在PostgreSQL中,常用的日期和时间数据类型包括:SMALLDATETIME、DATETIME、DATE、TIME和TIMESTAMP等。这些数据类型具有不同的精度和范围,适用于不同的应用场景。 在PostgreSQL中,我们可以使用to_char和to_timestamp函数进行时间格式转化。to_char函数用于将日期时间数据转换为特定格式的字符串,而to_timestamp函数则用于将字符...
将timestamp格式转换为"YYYY-MM-DD HH:MI:SS"格式: SELECT TO_CHAR(timestamp_column, 'YYYY-MM-DD HH:MI:SS') FROM table_name; 复制代码 将timestamp格式转换为"Mon DD, YYYY HH12:MI:SS PM"格式: SELECT TO_CHAR(timestamp_column, 'Mon DD, YYYY HH12:MI:SS PM') FROM table_name; 复...
使用to_timestamp替代 1. 2. 例: Select t.TXSJ<to_timestamp( endTime ,'yyyy-mm-dd hh24:mi:ss') 1. 11.nvl2 nvl2(列名,‘1’,‘0’),与nvl相比多参数 例: select nvl2(c.readtime,'1','0') as rtime from C c 多参数需要使用case when替代 1. 2. 例: select (case when readtime...

I am creating a view in PostgreSQL. I have a table with a column year as type integer and want to convert it to a timestamp without time zone in new column with specific month/day, for example:year | date --- 1999 | 1999-08-31 0 | 0 All years should...
I want the new columncreate_time_utcto be the unix time in milliseconds (i.e number of milliseconds since Unix epoch January 1 1970). I know I need to convert the postgrestimestampto a bigint, but I'm not sure how to do that. ...
timestamp("updated_at",{mode:"date",precision:3,// 3 for milliseconds}) According to the Postgres doc, Postgres default to the precision of the literal value, so it should have been 3 by default, no? Currently facing the same issue on a returning query, when I Select it normally it ...
