Indicates the overall success or failure of the function

Each function in ODBC returns a code, known as its return code, which indicates the overall success or failure of the function. Program logic is generally based on return codes. See [ODBC reference][1] [1]: https://docs.microsoft.com/en-us/sql/odbc/reference/develop-app/return-codes-odbc

Variants

SQL_INVALID_HANDLE

Function failed due to an invalid environment, connection, statement, or descriptor handle

This indicates a programming error. No additional information is available from SQLGetDiagRec or SQLGetDiagField. This code is returned only when the handle is a null pointer or is the wrong type, such as when a statement handle is passed for an argument a connection handle.

SQL_ERROR

Function failed

The application calls SQLGetDiagRec or SQLGetDiagField to retrieve additional information. The contents of any output arguments to the function are undefined.

SQL_SUCCESS

Function completed successfully

The application calls SQLGetDiagField to retrieve additional information from the header record.

SQL_SUCCESS_WITH_INFO

Function completed successfully, possibly with a nonfatal error (warning)

The application calls SQLGetDiagRec or SQLGetDiagField to retrieve additional information.

SQL_STILL_EXECUTING

A function that was started asynchronously is still executing

The application SQLGetDiagRec or SQLGetDiagField to retrieve additional information if any.

SQL_NEED_DATA

More data is needed

,such as when a parameter data is sent at execution time or additional connection information is required. The application calls SQLGetDiagRec or SQLGetDiagField to retrieve additional information, if any.

SQL_NO_DATA

No more data was available

The application calls SQLGetDiagRec or SQLGetDiagField to retrieve additional information. One or more driver-defined status records in class 02xxx may be returned.

SQL_PARAM_DATA_AVAILABLE

Trait Implementations

impl Clone for SQLRETURN

fn clone(&self) -> SQLRETURN

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SQLRETURN

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq<SQLRETURN> for SQLRETURN

fn eq(&self, other: &SQLRETURN) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
