Generic encoder for JDBC arrays.

Generic encoder for JDBC arrays.

Creates JDBC array decoder for type T which is already supported by database as array element.

Transform jdbcType int using parseJdbcType and calls overloaded method to create Encoder

Creates JDBC array encoder for type T which is already supported by database as array element.

Parses instances of java.sql.Types to string form so it can be used in creation of sql arrays. Some databases does not support each of generic types, hence it's welcome to override this method and provide alternatives to non-existent types.

Execute SQL on connection and return prepared statement. Closes the statement in a bracket.

Execute instructions in a transaction. For example, to add a Person row to the database and return the contents of the Person table immediately after that:

 val a = run(query[Person].insert(Person(...)): ZIO[Has[DataSource], SQLException, Long]
 val b = run(query[Person]): ZIO[Has[DataSource], SQLException, Person]
 transaction(a *> b): ZIO[Has[DataSource], SQLException, Person]

The order of operations run in the case that a new connection needs to be aquired are as follows:

 getDS from env,
 acquire-connection,
   set-no-autocommit(connection),
     put-into-fiberref(connection),
       op - the corresponding execute_ method which will execute and pull connection from the fiberref,
     remove-from-fiberref(connection),
   set-prev-autocommit(connection),
 release-conn

Since we are immediately executing the ZIO that creates this fiber ref whether it is global is not really relevant since it does not really use scope However if it were used for something else it would be scoped to the fiber-ref of the zio-jdbc context's creator i.e. the global scope.
