Provided Methods

fn SQLGetDiagFieldA<A: Ident<Type = SQLSMALLINT>, T>( &self, RecNumber: NonZeroI16, DiagIdentifier: A, DiagInfoPtr: Option<&mut T>, StringLengthPtr: Option<&mut MaybeUninit<T::StrLen>>, ) -> SQLRETURN

where T: AttrGet<A> + Ansi + ?Sized + DiagField<Self, A>, MaybeUninit<T::StrLen>: StrLen<SQLSMALLINT>,

Returns the current value of a field of a record of the diagnostic data structure (associated with a specified handle) that contains error, warning, and status information.

For complete documentation on SQLGetDiagFieldA, see API reference.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, SQL_INVALID_HANDLE, or SQL_NO_DATA.

fn SQLGetDiagFieldW<A: Ident<Type = SQLSMALLINT>, T>( &self, RecNumber: NonZeroI16, DiagIdentifier: A, DiagInfoPtr: Option<&mut T>, StringLengthPtr: Option<&mut MaybeUninit<T::StrLen>>, ) -> SQLRETURN

where T: AttrGet<A> + Unicode + ?Sized + DiagField<Self, A>, MaybeUninit<T::StrLen>: StrLen<SQLSMALLINT>,

Returns the current value of a field of a record of the diagnostic data structure (associated with a specified handle) that contains error, warning, and status information.

For complete documentation on SQLGetDiagFieldW, see API reference.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, SQL_INVALID_HANDLE, or SQL_NO_DATA.

fn SQLGetDiagRecA( &self, RecNumber: NonZeroI16, SQLState: &mut MaybeUninit<SQLSTATE<SQLCHAR>>, NativeErrorPtr: &mut impl AsMutPtr<SQLINTEGER>, MessageText: &mut OdbcStr<MaybeUninit<SQLCHAR>>, TextLengthPtr: &mut impl AsMutPtr<SQLSMALLINT>, ) -> SQLRETURN

Returns the current values of multiple fields of a diagnostic record that contains error, warning, and status information. Unlike SQLGetDiagField, which returns one diagnostic field per call, SQLGetDiagRec returns several commonly used fields of a diagnostic record, including the SQLSTATE, the native error code, and the diagnostic message text.

For complete documentation on SQLGetDiagRecA, see API reference.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

fn SQLGetDiagRecW( &self, RecNumber: NonZeroI16, SQLState: &mut MaybeUninit<SQLSTATE<SQLWCHAR>>, NativeErrorPtr: &mut impl AsMutPtr<SQLINTEGER>, MessageText: &mut OdbcStr<MaybeUninit<SQLWCHAR>>, TextLengthPtr: &mut impl AsMutPtr<SQLSMALLINT>, ) -> SQLRETURN

Returns the current values of multiple fields of a diagnostic record that contains error, warning, and status information. Unlike SQLGetDiagField, which returns one diagnostic field per call, SQLGetDiagRec returns several commonly used fields of a diagnostic record, including the SQLSTATE, the native error code, and the diagnostic message text.

For complete documentation on SQLGetDiagRecW, see API reference.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
