Hi ​@salah.elfarissi,

Thank you for the post!
You could try using the AttributeRenamer before the FeatureWrtier.

Let’s say:

• Your incoming features have a dynamic attribute that should be the primary key.

• You know the name of that attribute from a user parameter.

You can rename that attribute to a consistent name.

• Use an AttributeRenamer before the FeatureWriter.

• Set:

  • Source Attribute: @Value(PrimaryKeyName)

  • Destination Attribute: pk_field

• In the FeatureWriter, set Primary Key Name to pk_field

Let me know if this works!

Hello

Thank you for your response.

I think I was not clear on what I want to achieve.

I want the primary key name that my user choses be the one to use to define the primary key in my PostGIS table.

For example, if my user choses test_pk as the name of the primary key, it is test_pk to be used as the primary key and not pk_field.

The user expects to see test_pk as a primary key in his postgres tables.
