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

Currently, tree.NotExpr is not implemented natively in the vectorized engine, so we have to fallback to the older row-by-row engine to evaluate it. We should, instead, vectorize NotExpr.

I think the implementation will be quite similar to how tree.IsNullExpr is implemented, and I think we will want to implement two versions of NotExpr operator:

• one for projections, which populates a

We already have some scripts in the scripts directory. It would be good to run them for every PR.
This is also a great task for beginners.

Currently we only support Upsert for CockroachDB. Implementing same for MySQL should be pretty straightforward as well.

Wonder if we can also use INSERT ON CONFLICT UPDATE for PostgreSQL to ensure operation with same signature also works.

Hi community,

I found shardingsphere-db-discovery-mgr module need to add unit test. it 's task list :

• MGRDatabaseDiscoveryType.startPeriodicalUpdate()
• MGRDatabaseDiscoveryType.updateProperties()

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".

Hello Philip!
I think there is an issue with this part of the code of rqlite (store/store.go).

func (s *Store) Database(leader bool) ([]byte, error) {
	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
	}
	// Ensure only one snapshot can take place at once, and block all queries.
	s.mu.Lock()
	defer s.mu.Unlock()

	f, err := ioutil.TempFile("", "rqlilte-snap-

Whenever I submit a GET request to the api/public/groups endpoint, the "collections" field for each group returns "None" on every group, even if they have access to collections. I can verify that the

The goal is to create thin, easy to use PHP client for sending ILP messages. We already have a Java client:
