我准备了以下mysql select查询来检索一些数据。
这是选择查询，
SELECT MA.agentCode,MA.agentName,MP.code,MP.name, SUM(LG.ITEM_QTY) AS 'TOTAL',LG.FK_PUBLICATION
,SUM(RAI.REURN_COUNT) AS 'TOTAL_RETURNS'
FROM LABEL_GENERATED_ORDER_ITEM LG
INNER JOIN MSTR_PUBLICATION MP ON MP.id=LG.FK_PUBLICATION
INNER JOIN RETURNS_ACCEPTANCE_FLOW RA ON RA.FK_AGENT=LG.FK_AGENT
INNER JOIN MSTR_AGENT MA ON MA.id=LG.FK_AGENT
INNER JOIN RETURNS_ACCEPTANCE_FLOW_ITEM RAI ON RAI.FK_RETURN_ACCEPTANCE_FLOW=RA.ID
WHERE MA.SALES_INCENTIVE_ALLOWED=1 AND MA.FK_AGENT_TYPE=1 AND
LG.CIRCULATION_DATE BETWEEN '2017-05-01' and '2017-05-29'
AND RAI.SCANNED_DATE BETWEEN '2017-05-01' and '2017-05-29'
AND RAI.IS_NORMAL_APPROVED=1 AND
RAI.IS_SPECIAL_APPROVED=1
GROUP BY MA.agentCode, MP.code ,MA.agentName,MP.name,LG.FK_PUBLICATION
ORDER BY MA.agentCode ASC, MP.code ASC;
以上查询运行正常。 但是执行需要很多时间。我想减少/优化查询的执行时间。
选择查询的结果为文本，
agentCode agentName code name TOTAL FK_PUBLICATION TOTAL_RETURNS
