+// SQLite is dynamically typed.
+// Columns can mostly hold any value regardless of their declared type.
+// SQLite supports most [driver.Value] types out of the box,
+// but bool and [time.Time] require special care.
+//
+// Booleans can be stored on any column type and scanned back to a *bool.
+// However, if scanned to a *any, booleans may either become an
+// int64, string or bool, depending on the declared type of the column.
+// If you use BOOLEAN for your column type,
+// 1 and 0 will always scan as true and false.
+//
 // # Working with time
 //
+// Time values can similarly be stored on any column type.
 // The time encoding/decoding format can be specified using "_timefmt":
 //
 //	sql.Open("sqlite3", "file:demo.db?_timefmt=sqlite")
 //
-// Possible values are: "auto" (the default), "sqlite", "rfc3339";
