TODO: <a href="https://golang.org/cl/258360">https://golang.org/cl/258360</a>: close driver.Connector if it implements io.Closer
|
||||
The <a href="/pkg/database/sql/#DB.Close"><code>DB.Close</code></a> method now closes
|
||||
the <code>connector</code> field if the type in this field implements the
|
||||
<a href="/pkg/io/#Closer"><code>io.Closer</code></a> interface.

TODO: <a href="https://golang.org/cl/311572">https://golang.org/cl/311572</a>: add NullInt16 and NullByte
|
||||
The new
|

<a href="/pkg/database/sql/#NullInt16"><code>NullInt16</code></a>
|
||||
and
|
||||
<a href="/pkg/database/sql/#NullByte"><code>NullByte</code></a>
|
||||
structs represent the int16 and byte values that may be null. These can be used as
|
||||
destinations of the <a href="/pkg/database/sql/#Scan"><code>Scan</code></a> method,
|
||||
similar to NullString.
