Duplicate column name 'keywords'

这个错误通常是因为在查询语句中存在重复的列名。请检查你的查询语句，确保所有的列名都是唯一的。你可以通过为每个列指定别名来解决这个问题。例如：

SELECT column1, column2, column3 AS keywords1, column4 AS keywords2 FROM table_name;

这个查询语句将会把"column3"列的别名设置为"keywords1"，把"column4"列的别名设置为"keywords2"，从而避免了重复列名的问题。

A "duplicate column name" error occurs when there are two or more columns in a database table with the same name. This can happen when a table is created or altered and the same column name is used more than once. It can also happen when data is imported from different sources and there are overlapping column names. To resolve this error, one of the duplicate column names needs to be changed to a unique name. This can be done by altering the table structure or renaming the column. It is important to ensure that all queries and applications that use the table are updated to reflect the new column name.
