Updating Data Sources – improvements at Pro

Project/Map/Layer/Table/LayerFile.updateConnectionProperties (current_connection_info, new_connection_info, {auto_update_joins_and_relates}, {validate})

Find this path:

Replace it with this path:

.APRXs

Updating Data Sources – Improvements

1. Changing a folder

2. Changing FGDB to SDE

3. Changing PGDB to FGDB

Updating Data Sources advanced concepts – Layer.connectionProperties

• New at Pro • The entire layer data source object model is exposed as a Python dictionary.• Use if you need more fine grained control than what’s available in

Project/Map/Layer/Table/LayerFile.updateConnectionproperties()• Useful when dealing with joins and relates or Enterprise Geodatabase

Access a layer in a map.

File Geodatabase layer connection properties dictionary

Get layer’s connection properties.

Updating Data Sources advanced concepts – Layer.connectionProperties• File Geodatabase layer connection Properties (with joins and relates)• It gets complicated!

Layer’s database

List of relates on the layer

Relate properties

Updating Data Sources advanced concepts – Layer.connectionProperties• Two ways to use the connection properties dictionary

1. Write directly to the dictionary

2. UpdateConnectionProperties will also do find and replace for full and partial dictionaries

Access a layer in a map.Get it’s connection properties.

Update connection properties dictionary.

Find this dictionary key/value pair.

Replace it with this key/value pair

Updating Data Sources advanced concepts – Layer.connectionProperties• Enterprise Geodatabase examples – change instance or server

Enterprise Geodatabase connection properties dictionary

Old database info

New database info

Update connection properties for project
