Member Data Documentation

int tds_dynamic::emulated

this dynamic query cannot be prepared so libTDS have to construct a simple query. This can happen for instance is tds protocol doesn't support dynamics or trying to prepare query under Sybase that have BLOBs as parameters.

char tds_dynamic::id[30]

id of dynamic. Usually this id correspond to server one but if not specified is generated automatically by libTDS

TDSPARAMINFO* tds_dynamic::params

query parameters. Mostly used executing query however is a good idea to prepare query again if parameter type change in an incompatible way (ie different types or larger size). Is also better to prepare a query knowing parameter types earlier.
