<p>

The <a href="/pkg/database/sql#IsolationLevel"><code>IsolationLevel</code></a>
|
||||
can now be set when starting a transaction by setting the isolation level
|
||||
on the <code>Context</code> then passing that <code>Context</code> to
|
||||
<a href="/pkg/database/sql#DB.BeginContext"><code>DB.BeginContext</code></a>.
|
||||
on <a href="/pkg/database/sql#TxOptions.Isolation"><code>TxOptions.Isolation</code></a> and passing
|
||||
it to <a href="/pkg/database/sql#DB.BeginTx"><code>DB.BeginTx</code></a>.
|
||||
An error will be returned if an isolation level is selected that the driver
|
||||
does not support. A read-only attribute may also be set on the transaction
|
||||
with <a href="/pkg/database/sql/#ReadOnlyContext"><code>ReadOnlyContext</code></a>.
|
||||
by setting <a href="/pkg/database/sql/#TxOptions.ReadOnly"><code>TxOptions.ReadOnly</code></a>
|
||||
to true.
|
||||
</p>
|
||||
<p>
|
||||
Queries now expose the SQL column type information for drivers that support it.
