#[repr(i16)] #[must_use]pub enum SQLRETURN { SQL_INVALID_HANDLE, SQL_ERROR, SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_STILL_EXECUTING, SQL_NEED_DATA, SQL_NO_DATA, SQL_PARAM_DATA_AVAILABLE, }
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.
