During INSERT and UPDATE operations, Oracle converts the value to the data type of the affected column. During SELECT FROM operations, Oracle converts the data from the column to the type of the target variable. When manipulating numeric values, Oracle usually adjusts precision and scale to all...

这样：select to_number('123') from dual oracle没有显示的INT型，你直接定义成number就好，强制类型转换函数都差不多，转换为日期型就是TO_DATE(),转换为数字就是TO_NUM(),转换为字符就是TO_CHAR（），括号中跟需要转换的内容，日期型注意格式掩码。
In this function, the expression is the value you want to convert, and the type_name is the data type you’re converting to. You can specify several types here, but NUMBER is the only numeric type you can use. For example: CAST('200'ASNUMBER) ...
