Fragile connection behavior using Serverless Azure SQL database #11153

Open sgellock opened 4 years ago

sgellock commented 4 years ago

Issue Type: Bug

  1. run an Azure SQL Serverless database
  2. connect to the database using Azure Data Studio
  3. once connected, create a new query, File -> New Query
  4. write any simple query against any table you wish. Do not save the query. Leave it in an unsaved query file (e.g. SQLQuery_1)
  5. run the query, see the successful results of the query
  6. now let enough time to pass that the serverless database gets put into a paused state. for me, that's about an hour or so.
  7. once the database is in a paused state, attempt to rerun the query from step 5

results, the query is not able to connect to the database and successfully run.
multiple attempts at running the query produce differing error behavior, and in some cases the query window crashes and is lost. This behavior appears to happen even when the paused database is started and in a running state.

If you create a new query (File -> New Query) and copy and paste the TSQL from the query in step 4 into this new query, it will run successfully
