Oracle: How to find the timestamp of the last update (any table) within a schema?

由 生来就可爱ヽ(ⅴ＜●) 提交于 2020-01-01 08:47:16

What would be the most effective way to check the whole schema

问题 I am looking for the XSD schema of RSS. Via Wikipedia I have found several pages on the specifications of RSS 2.0 but none offers an XSD schema.

Mongoose schema optional fields

由 冷暖自知 提交于 2020-01-01 01:12:09
问题 I have a user schema with mongoose in nodejs like this userschema = mongoose.Schema({ org: String, username: String, fullname: String, password: String, email: String }); Except sometimes I need to add some more fields. The main question is: Can I have optional fields in a monogoose schema? 回答1: All fields in a mongoose schema are optional by default (besides _id , of course). A field is only required if you add required: true to its definition. So define your schema as the superset of all

How to kill all active and inactive oracle sessions for user

由 旧城冷巷雨未停 提交于 2019-12-31 08:37:11
问题 I am trying the below script to kill all active and inactive oracle sessions for user at once but it doesn't work. The script executes successfully but does not kill sessions for user. BEGIN FOR r IN (select sid,serial# from v$session where username = 'USER') LOOP EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid || ',' || r.serial# || ''''; END LOOP; END; 回答1: The KILL SESSION command doesn't actually kill the session. It merely asks the session to kill itself. In some situations,

MongoDB: How to represent a schema diagram in a thesis?

由 烂漫一生 提交于 2019-12-31 08:15:04
问题 I am currently writing a thesis and need to display the schema of my MongoDB in a diagram. I have found no resources about diagrams for document-based databases. There are Entity Relationship Diagrams (ERD) for relational databases. What options do I have for MongoDB? I've noticed that a lot of blogs just display the raw JSON as their "diagram" but this isn't feasible in my thesis. Here is a sample of one of my JSON structures: //MultiChoiceQuestion { "title": "How are you?", "valid_answers"
