is not like是一个用于查询的条件语句,用于排除特定的模式或字符串。它可以在查询中使用,以筛选出不满足给定模式的记录。在引用中提到,使用not like null查询的结果集合永远为空,这意味着不会返回任何记录。在引用中提供了一个示例模型类,你可以根据自己的需求将is not like应用于该模型类的相应字段上,以实现具体的数据查询。

Sql not like
`Sql not like` is a SQL operator used to filter records in a table based on a specified pattern that is not present in the column data. For example, the following SQL statement selects all records from the "Customers" table where the "Country" column does not contain the pattern "USA":
```
SELECT * FROM Customers
WHERE Country NOT LIKE '%USA%';
```
This statement will return all records where the "Country" column does not contain the characters "USA" anywhere in the column data. The "NOT" keyword is used to negate the condition specified by the "LIKE" operator.
oracle regexp_not like
Oracle does not have a built-in function called `regexp_not like`. However, you can achieve a similar result by using the negation operator (`NOT`) with the `REGEXP_LIKE` function. Here's an example:
```sql
SELECT *
FROM your_table
WHERE NOT REGEXP_LIKE(your_column, 'your_pattern');
```
In the above query, `your_table` is the name of your table, `your_column` is the column you want to match against the regular expression pattern, and `your_pattern` is the regular expression pattern you want to exclude.
This query will return all the rows where the column value does not match the specified regular expression pattern.
