JPA Tools > Generate Entities from Tables, @Column strange format [message #1695808]

When using "Generate Entities from Tables" some columns are mapped to @Column(name="\"${column_name}\"") instead of @Column.
${column_name} is the actual column name.

Ex. if the column name is TYPE then this is generated ---> @Column(name="\"TYPE\"").

Can someone explain why this is happening.
Is this related to the column name ? (hopefully not)

It is indeed related to the column name. A column name will be delimited if the database platform you are using has listed that column name as a reserved word. In this case, it is very likely that "TYPE" is reserved, and as a result, to avoid confusion at runtime with generated SQL, this column name will be delimited to ensure there is no confusion with reserved words.
