Interface ISqliteFunctions
A dialect's renderer for the SQLite-only SQL surface exposed through Sqlite
(SqliteFunctions): the core scalars (printf/format, hex/unhex,
random/randomblob, quote, typeof, glob, unicode/char,
soundex, octet_length, if/ifnull), the JSON1 functions/operators/aggregates
(json_extract, ->/->>, json_set, json_group_array, ...), the
date functions (timediff, unixepoch, julianday), the math-extension functions
(acos, degrees, log2, mod, pi, ...) and the full-text (FTS3/FTS4/FTS5)
query surface (Match, Rank, FTS5bm25, Highlight, FTS3Offsets, ...).
The predicate and the renderer
live on one object, so a name the dialect reports as supported always has a rendering, and a provider
that cannot express the surface returns null from
SqliteFunctions.

Remarks
Unlike the stateless renderers, this object carries both the per-name predicate and the renderer,
hence the plural capability-noun name rather than the *Renderer suffix.
Methods
Render(string, IReadOnlyList<string>)
Renders the SQLite function name over the already-rendered
args. name is the CLR method name of the
SqliteFunctions member (for example printf, json_extract,
json_get).
string Render(string name, IReadOnlyList<string> args)
Parameters
namestringargsIReadOnlyList<string>
Returns
Supports(string)
True when the SQLite function name can be rendered.
bool Supports(string name)
Parameters
