|
|
This statement is used to show the execution of the specified export task
|
|
Grammar:
|
|
SHOW EXPORT
|
|
[FROM both names]

|
]

|
[ORDER BY ...]
|
|
[LIMIT limit];

3) Any column combination can be sorted using ORDER BY
|
|
4) If LIMIT is specified, the limit bar matching record is displayed. Otherwise, all of them will be displayed.
