pgsql todate
时间: 2023-10-09 14:05:05 浏览: 62
To convert a PostgreSQL date to a specific format, you can use the `to_char` function. Here's an example:
```sql
SELECT to_char(your_date_column, 'YYYY-MM-DD') AS formatted_date
FROM your_table;
```
Replace `your_date_column` with the column name that contains the date, and `your_table` with the table name.
You can customize the format according to your needs. In the example above, `'YYYY-MM-DD'` represents the year, month, and day in the format of four digits for the year, two digits for the month, and two digits for the day. You can refer to the PostgreSQL documentation for more format options: https://www.postgresql.org/docs/current/functions-formatting.html

pgSQL to_date
在pgSQL中,to_date函数用于将字符串转换为日期。然而,该函数仅转换年月日部分,并且无论在函数中指定的日期格式如何,都只会转换年月日。例如,使用to_date函数转换字符串'2019-01-15 18:33:41',结果仅为日期部分,即'2019-01-15'。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

pgsql insert date
在PostgreSQL中,插入日期可以使用INSERT INTO语句。根据你提供的示例,你可以使用以下语法来插入日期数据:
INSERT INTO table_name (column1, column2, column3, ... columnN) VALUES (value1, value2, value3, ... valueN);
其中,table_name是你要插入数据的表名,column1, column2, column3等是表中的列名,value1, value2, value3等是对应列的值。在你的示例中,你可以使用以下语句来插入日期数据:
INSERT INTO date_test (c1) VALUES (to_date('2019-06-05 19:55:44', 'yyyy-mm-dd hh24:mi:ss'));
这将在date_test表的c1列中插入日期值。你可以根据需要插入多行数据,只需在INSERT INTO语句中重复相应的VALUES子句即可。[1][2][3]
