PageHelper column ambiguously defined

The "PageHelper column ambiguously defined" error message typically occurs when using the PageHelper plugin in a Java application with a database query that involves multiple tables, and the column name specified in the query is ambiguous.
To resolve this issue, you can explicitly specify the table name or alias along with the column name in your query. By doing so, you can make sure that the column is unambiguous and can be correctly identified by the PageHelper plugin.
Here's an example of how you can specify the table name or alias in your query:
```java
@Select("SELECT t.column_name FROM table_name t WHERE t.some_other_column = #{someValue}")
List<String> getData(@Param("someValue") String someValue);
```
In this example, `t.column_name` explicitly specifies that the `column_name` is from the `table_name` table. Adjust the query and table/alias names according to your specific scenario to avoid the "PageHelper column ambiguously defined" error.
