Working on a project I ran into the documentation for customizing the Foreign Key.
The docs read:

// https://sequelize.org/master/manual/assocs.html
// For example, to use UUID as the foreign key data type instead of the default (INTEGER), you can simply do:

const { DataTypes } = require("Sequelize");

Foo.hasOne(Bar, {
  foreignKey: {
    // name: 'myFooId'
    type: D

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

Describe the bug
Using a time dimension on a runningTotal measure on Snowflake mixes quoted and unquoted columns in the query. This fails the query, because Snowflake has specific rules about quoted columns. Specifically:

  • All unquoted column names are treated as upper case
  • Quoted column names are case sensitive.

So "date_from" <> date_from

When I try to connect dolt server using golang's go-sql-driver/mysql driver in multiple heads mode, It seems that go-sql-driver/mysql driver does't support database with a sub name. DSN string format in go-sql-driver/mysql like [username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]. When dbname is "mydb", It works, but not work when dbname is "mydb/feature-branch".

Describe the bug

QuestDB throws an error if my query returns 0 rows when using SAMPLE BY. It works fine and responds 0 row found without SAMPLE BY.

My query (I run it on QuestDB web console directly)

SELECT ts, pair, side, round(nsum(size)) as size
FROM liquidations
WHERE pair = 'ETC-USDT-PERP' and side = 'sell' and size > 500
SAMPLE BY 1m
ALIGN TO CALENDAR WITH OFFSET '00:00'
