    <p>I've looked in the Golang documentation and haven't seen an example of how to achieve what I'm looking to do. Specifically, I'm trying to write a map from inodes, represented by <code>syscall.Stat_t.Ino</code>, which has type <code>uint64</code> on my machine, to ino_entry, defined as</p> <pre><code>type ino_entry struct { st *syscall.Stat_t nodes []string } </code></pre> <p>where nodes represents the names of all the files hard linked to the inode.</p> <p>However, I want to avoid putting the literal type <code>uint64</code> in the specification of the map if I can. That is, instead of writing <code>map [uint64] ino_entry</code>, I'd prefer to write <code>map [typeof(syscall.Stat_t.Ino)] ino_entry</code>, where <code>typeof(x)</code> returns the static (i.e., compile-time) type of <code>x</code>. I've tried <code>map [syscall.Stat_t.Ino] ino_entry</code> and, by analogy with type switches, <code>map [syscall.Stat_t.Ino.(type)] ino_entry</code>, but both of these are syntax errors. Needless to say, <code>map [reflect.Typeof(syscall.Stat_t.Ino)] ino_entry</code> doesn't work. As far as I can tell, the only way to implement this without hardcoding the type of the structure element is to use <code>inomap := make(map [interface{}] ino_entry)</code> and then access the elements using type assertions (I don't know the correct syntax for this though).</p> <p>Is there a way to declare the type of a variable based on the static type of another variable, or struct or interface member, without hardcoding that type explicitly?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
