71 <!-- Any of these can throw:
72 vx.db.sqlerror - SQL statement error (text
73 parameter will include actual error)
74 vx.db.toomuchdata - Scalar or Recordset result
75 is too large to transmit in a single d-bus message. Will
76 need to use a different API (not yet defined). text
77 parameter will indicate what the problem is
78 vx.db.badschema - Schema returned by the query
79 contains features not supported (such as sql_variant).
80 text parameter will indicate what the problem is
81 vx.db.exception - Method threw an exception
82 other than those listed above. Text parameter will contain
83 the normal .NET exception description and backtrace
88 - Execute particular procedures, not just SQL
89 - Ability to stream results as signals rather than in a single
90 message (allows interleaving results and larger sized result
