//
// SQLCommand executes SQL commands that are not queries. Any SQL statement
// that does not being with "SELECT" should be sent here. All SELECT
// statements should go to the SQLQuery function.
//
// Commands can be optionally paramterized using ?, such as:
//
// INSERT INTO Foo VALUES(a, b, c) (?, ?, ?)
//
// The values for the placeholders (currently) must be provided as strings.
//
// Constraints (for now):
// 1. cmds with only simple positional parameters allowed
// 2. cmds with lists of parameters ("complex") NOT allowed
// 3. parameter types allowed: string only for now
//
// SQL commands in OrientDB tend to return one of two types - a string return value or
// one or more documents. The meaning are specific to the type of query.
//
// ----------------
// For example:
// ----------------
// for a DELETE statement:
// retval = number of rows deleted (as a string)
// docs = empty list
//
// for an INSERT statement:
// n = ?
// docs = ?
//
// for an CREATE CLASS statement:
// retval = cluster id of the class (TODO: or it might be number of classes in cluster)
// docs = empty list
//
// for an DROP CLASS statement:
// retval = "true" if successful, "" if class didn't exist (technically it returns null)
// docs = empty list
