Class Description

void initResultSet(Statement *stmt)
 Oracle query result.
TOracleResult(Connection *conn, Statement *stmt)


 TOracleResult(Connection *conn, const char *tableName)


 This construction func is only used to get table metainfo.



 ~TOracleResult()


 Cleanup Oracle query result.



void Close(Option_t *)


 Close query result.



Bool_t IsValid(Int_t field)

Int_t GetFieldCount()


 Get number of fields in result.



const char * GetFieldName(Int_t field)


 Get name of specified field.



TSQLRow * Next()
