PostgreSQL has a rich set of native data types available to users. Users can add new types to PostgreSQL using the CREATE TYPE command. PostgreSQL有一组丰富的本地数据类型可供用户使用。用户可以使用CREATE TYPE命令向PostgreSQL添加新类型。Each data type has an external representation determined by its...
Your framework needs to generate DDL that uses "timestamp" rather than "datetime". When any application framework generates the wrong data types for SQL DDL, the most likely problem is that it's configured to use the wrong database. In your case, it's likely still configured to use MySQL...

参照资料:http://www.postgres.cn/docs/9.4/datatype-datetime.html image.png 资料中的两句话,可以解释最初的问题: “timestamp类型等于timestamp without time zone 类型” “如果一个文本已被确定是timestamp without time zone,PostgreSQL 将悄悄忽略任何文本中指出的时区。” 分析: now()会根据当前会话中使用...
在C#中使用PostgreSQL插入DateTime值的方法如下: 1. 首先,确保你的C#项目中已经引用了 Npgsql 库,它是 PostgreSQL 数据库的官方驱动程序。 2. 创建一个 ...
我创建了带有迁移的PostgreSQL时间戳字段: $table->dateTime('start_date'); 我尝试插入用strtotime生成的时间戳,并收到了一个错误: Invalid datetime format: 7 ERROR: invalid input syntax for type timestamp: "1383321600" 对它进行黑客攻击是有效的: new MyModel(array('start_date' => DB::raw("to_...
Binary representations for integers use network byte order (most significant byte first). For other data types consult the documentation or source code to learn about the binary representation. Keep in mind that binary representations for complex data types might change across server versions; the ...

Documentation: 8.3: Message Data Types 这一节描述报文中的基本数据类型。 Intn(i) 一个网络字节序的n bit整数,如果i指定了,则表示实际出现的数字,否则这个值为变量。例如 Int16、 Int32(42)。 Intn[k] 一个k个元素的n bit整数的数组,网络字节序。数组长度k是由报文的前一字段决定的。 String(s) 一...
