Struct odbc_sys::SqlReturn [−][src]
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
Implementations
impl SqlReturn
[src]
pub const INVALID_HANDLE: SqlReturn
[src]
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.
pub const ERROR: SqlReturn
[src]
Function failed
The application calls SQLGetDiagRec
or SQLGetDiagField
to retrieve additional
information. The contents of any output arguments to the function are undefined.
pub const SUCCESS: SqlReturn
[src]
Function completed successfully
The application calls SQLGetDiagField
to retrieve additional information from the header
record.
pub const SUCCESS_WITH_INFO: SqlReturn
[src]
Function completed successfully, possibly with a nonfatal error (warning)
The application calls SQLGetDiagRec
or SQLGetDiagField
to retrieve additional
information.
pub const STILL_EXECUTING: SqlReturn
[src]
A function that was started asynchronously is still executing
The application SQLGetDiagRec
or SQLGetDiagField
to retrieve additional information if
any.
pub const NEED_DATA: SqlReturn
[src]
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.
pub const NO_DATA: SqlReturn
[src]
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.
