## Stable Builds
|
||||
|
||||
* 2020-08-05 -- 1.1.582
|
||||
* Fix #138 by exposing `next.jdbc.connection/jdbc-url` to build `:jdbcUrl` values that can be passed to `->pool` or `component`.
|
||||
|
||||
* 2020-08-03 -- 1.1.581
|
||||
* Fix #137 by adding support for specifying username and password per-connection (if your datasource supports this).
|
||||
* Document SQLite handling of `bool` and `bit` columns in a new **Tips & Tricks** section, inspired by #134.

This project follows the version scheme MAJOR.MINOR.COMMITS where MAJOR and MINOR provide some relative indication of the size of the change, but do not follow semantic versioning. In general, all changes endeavor to be non-breaking (by moving to new names rather than by breaking existing names). COMMITS is an ever-increasing counter of commits since the beginning of this repository.

"Given a database spec (as a hash map), return a JDBC URL with all the

attributes added to the query string. The result is suitable for use in
|

calls to `->pool` and `component` as the `:jdbcUrl` key in the parameter
|
||||
map for the connection pooling library.
|
||||
|
||||
This allows you to build a connection-pooled datasource that needs
|
||||
additional settings that the pooling library does not support, such as
|
||||
`:serverTimezone`:
|
||||
|
||||
```clojure
|
||||
(def db-spec {:dbtype .. :dbname .. :user .. :password ..
|
||||
:serverTimezone \"UTC\"})
|

HikariCP {:jdbcUrl (next.jdbc.connection/jdbc-url db-spec)
|
||||
:maximumPoolSize 15}))
|
||||
```
|
||||
|
||||
This also clearly separates the attributes that should be part of the
|
||||
JDBC URL from the attributes that should be configured on the pool.
|
||||
|
||||
Since JDBC drivers can handle URL encoding differently, if you are
|
||||
trying to pass attributes that might need encoding, you should make
|
||||
sure they are properly URL-encoded as values in the database spec hash map.
|
||||
This function does **not** attempt to URL-encode values for you!"
