即使不同的数据库以相同的语义支持 SQL 类型,它们也可能用不同的名称。例如,绝大多数的主流数据库都支持一种表示大型二进制值的 SQL 类型,但 Oracle 把这种类型叫做LONG RAW,Sybase 把它叫做IMAGE,Informix 却把它叫做BYTE,而 DB2 又把它叫做LONG VARCHAR FOR BIT DATA。
oracleCase 是否返回列名、表名的大写。取值如下: false(默认):不对返回的列名、表名进行转换。 true:返回的列名、表名直接全部转换成大写。 strict:返回的列名、表名在字母全部都是小写的情况下转换成大写。 resetNlsFormat 是否支持将date/timestamp/timestamptz类型默认按照标准格式去识别。取值如下: ...
JDBC使用步骤总结: 1. 创建数据库连接 Connection 2. 创建操作命令 Statement 3. 使用操作命令来执行 SQL 4. 处理结果集 ResultSet 5. 释放资源 这里可以看到Java使用数据库的代码非常多,而且每次连接都需要重复这个过程,于是就有大佬写了数据库框架Mybatis,把上面的代码都封装了起来,用的时候只需要一条注解就可以...
