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

There are several optimization the execution engine can perform when evaluating LIKE patterns with %, which matches zero or any number of any character. For example, see #80073.

Sequential %s can prevent these optimizations, but they are semantically equivalent to a single %, so the optimizer should normalize them to a single %.

For example:

-- The following expressions 

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.

Hi community,

This issue is for WeOpen-Star

Add unit test for ClusterContextManagerCoordinator.renew(final SchemaDeletedEvent event).

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.

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

Using dolt sql -q "<query>" -r csv > file.csv results in newlines in the output data:

Describe the Bug

The JSON response sent back over HTTP doesn't encode certain characters correctly.

For example, if a value in a string column contains the char \1 the byte value is copied verbatim in the response, breaking the client:

>>> json.loads('"\1"')
...
json.decoder.JSONDecodeError: Invalid control character at: line 1 column 2 (char 1)

Instead, we shou

• Missing information on how to create other databases
• Missing information on how to switch to other databases
• When using time travel, we don’t know where to get the transaction number from - we should show this to the user after committing data (this may be a missing capability in immudb / tools).
• The last long query example in the quick start is incorrect (incorrect
