Library: Data/ODBC
Package: ODBC
Header: Poco/Data/ODBC/Diagnostics.h
Description
Utility class providing functionality for retrieving ODBC diagnostic records. Diagnostics object must be created with corresponding handle as constructor argument. During construction, diagnostic records fields are populated and the object is ready for querying.
Member Summary
Member Functions: begin, connectionName, count, diagnostics, end, fields, message, nativeError, reset, serverName, sqlState
Nested Classes
struct DiagnosticFields
SQLGetDiagRec fields
Types
FieldVec
typedef std::vector < DiagnosticFields > FieldVec;
Iterator
typedef typename FieldVec::const_iterator Iterator;
Constructors
Diagnostics
explicit Diagnostics(
const H & handle
);
Creates and initializes the Diagnostics.
Destructor
~Diagnostics
~Diagnostics();
Destroys the Diagnostics.
Member Functions
begin
Iterator begin() const;
connectionName
std::string connectionName() const;
Returns the connection name. If there is no active connection, connection name defaults to NONE. If connection name is not applicable for query context (such as when querying environment handle), connection name defaults to NOT_APPLICABLE.
count
int count() const;
Returns the number of contained diagnostic records.
diagnostics
const Diagnostics & diagnostics();
end
Iterator end() const;
fields
const FieldVec & fields() const;
message
std::string message(
int index
) const;
Returns error message.
nativeError
long nativeError(
int index
) const;
Returns native error code.
reset
void reset();
Resets the diagnostic fields container.
serverName
std::string serverName() const;
Returns the server name. If the connection has not been established, server name defaults to NONE. If server name is not applicable for query context (such as when querying environment handle), connection name defaults to NOT_APPLICABLE.
sqlState
std::string sqlState(
int index
) const;
Returns SQL state.
Variables
DATA_TRUNCATED
static const std::string DATA_TRUNCATED;

SQL_NAME_LENGTH
static const unsigned int SQL_NAME_LENGTH = 128;
