Using an mi_get_result() Loop
The DataBlade API
mi_get_result()
function returns the status of the current statement on a particular connection. The current statement is the most recent statement sent to the database server on the connection. Only one statement is current at a time. The
mi_get_result()
function can provide any of the following information about the current statement to the application:
The statement generated an error (
MI_ERROR
or
NULL
).
A
DML
(data manipulation language) statement completed (
MI_DML
).
A
DDL
(data definition language) statement completed (
MI_DDL
).
The statement produced row data that the application must fetch (
MI_ROWS
).
No more results are pending (
MI_NO_MORE_RESULTS
).
The
mi_get_result()
function is usually executed in a loop after
mi_exec()
sends a statement to the database server. The loop terminates when
mi_get_result()
returns
MI_NO_MORE_RESULTS
. Think of the
mi_get_result()
loop as an iteration over the states of the database server.
