oracle 没有boolean,mysql用bit(1)而oracle可以用char(1) check(...(0,1))字段, 如: create table a ( a char(1) check (a in(0,1))) 然后JDBC用getBoolean()可以返回正确的结果。 JDBC我用ojdbc14.jar ps:以上内容均引自网络,请尊重原作者,这里仅为学习。
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html 但遗憾的是,官网唯独没有明确说明boolean类型占几个字节,原文如下: boolean: The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. ...
Oracle Boolean Is there a boolean data type in Oracle SQL? No, there isn’t. You can’t declare a column with the BOOLEAN data type. However, there are several alternatives, which I’ve detailed below. The recommended way of storing booleans in Oracle SQL is to use a NUMBER(1) field...
Oracle 官方文档地址在此:https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html 总共8 大基础数据类型,其余 7 个都非常明确的标明了占用多少字节,只有 boolean 模棱两可: boolean: Thebooleandata type has only two possible values:trueandfalse. Use this data type for simple flags tha...
oracle中创建表的时候用boolean类型怎么建表 oracle中除了在pl/sql中外,本身没有boolean类型。所以oracle建表的时候,如果想用bool类型,那么就需要check比如建表语句(a char(1) check(a in (0,1))),当然未必是0,1,用t,f也行,只要能表示就行,0,1的话,jdbc读取的时
