I am exporting data from database for that I have written following query:

SELECT ParameterID, Name,Type,Datatype,LogDate
FROM Param_Ems
WHERE DataType = 10
INTO OUTFILE 'C:/tmp/ParamData.csv'

Is there any way to export and delete these records within the same query?

  • There is no standard SQL (as far as I know ) to achieve this. Are you trying to achieve a better performance or you can't run two queries? Your objective is not clear to me. – Masoud Jun 22 '15 at 5:16
  • I want to clear exported data from database after exporting – Sush Jun 22 '15 at 5:53
  • Yeah... I understood your question but don't know why are you trying to do this?! because alternatives are not any faster than running the query twice. – Masoud Jun 22 '15 at 6:23
  • Because same data will be log into database again. – Sush Jun 22 '15 at 6:30
  • I just find the solution in one query if not then i have to make two queries – Sush Jun 22 '15 at 6:31

Use pt-archiver tool. It can delete data that it moves. Alternatively use drop & create after the select into outfile.


Put the SELECT INTO OUTFILE and TRUNCATE (or DROP) TABLE in a stored procedure; then CALL the SP.

(Caveat: I am not sure if those two statements can be performed in a SP.)

    And TRUNCATE does an auto-commit, if I remember right. – ypercubeᵀᴹ Jun 22 '15 at 23:31
  • The commit would probably be OK. If not, the change to a DELETE, which would be slower. – Rick James Jun 23 '15 at 1:27
