Function PreparedImpl.this

Submit an SQL command to the server to be compiled into a prepared statement.

this (
  Connection conn,
  string sql
);

The result of a successful outcome will be a statement handle - an ID - for the prepared statement, a count of the parameters required for excution of the statement, and a count of the columns that will be present in any result set that the command generates. These values will be stored in the Command struct.

The server will then proceed to send prepared statement headers, including parameter descriptions, and result set field descriptions, followed by an EOF packet.

If there is an existing statement handle in the Command struct, that prepared statement is released.
