function hook_chado_node_sync_select_query

2.x hook_chado_node_sync_select_query($query)

Alter the query that retrieves records to be sync'd (optional)

This might be necessary if you need fields from other chado tables to create your node or if your chado node type only supports a subset of a given table (ie: a germplasm node type might only support node creation for cerain types of stock records in which case you would need to filter the results to only those types).

Note: For your own module, replace hook in the function name with the machine-name of your chado node type (ie: chado_feature).

Use :placeholders for values. 'where_args: An associative array of arguments to be subbed in to the where clause where the
