database - Orientdb SQL query to check edge properties -


i have graph database 3 simple vertex types, user, device , sensor. relationship goes as,

edges: userhasdevices, devicehassensors

each edge has property name "isdeleted". when deleting vertex, don't make deleted permanently make "isdeleted" property of edge "true". please let me know how query list of deleted sensors, , / or deleted list of devices, belongs particular user, identified user id.

to filter edges property, can use oute('edgename') , put conditions in brackets. supposed work according understanding :

select expand(oute('userhasdevices')[isdeleted = true].inv()) #13:12

in question, asker says doesn't work.

i found way this. can expand edges. :

select expand(in) userhasdevices isdeleted = true , out = #13:12

but don't think best ideal store property in edge performance wise. best thing have edge contains "isdeleted" vertices. simpler , allow have smaller query execution time. eliminate need filter edge property.

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
