我有一个条件 IN 太长的 SQL。而且我的 SQL 执行时间太长，有什么办法可以提高它的性能吗？

这是SQL

SELECT * FROM bi_bunrui_syouhin_shop_day_jyutyuu AS bi   
WHERE bi.bunrui_code IN     
('0001','1000','1001','1005','1006','1007','1008','1009','1010','1011','1012','1013','1014','1015','1016','1017','1018','1020','1021','1022','1023','1030','1031','1032','1033','1034','1036','1037','1038','1039','1040','1041','1043','1044','1045','1046','1050','1054','1055','1060','1061','1070','1080','1081','1082','1083','1084','1085','1086','1088','1090','1091','1092','1093','1094','1095','1096','1097','1100','1101','1102','1103','1104','1105','1106','1107','1108','1109','1110','1111','1112','1113','1114','1115','1116','1117','1118','1119','1120','1121','1122','1123','1130','1131','1132','1133','1134','1135','1136','1137','1140','1141','1142','1143','1145','1148','1150','1151','1152','1153','1154','1155','1156','1157','1160','1161','1162','1163','1164','1165','1166','1167','1168','1169','1170','1171','1180','1181','1182','1183','1184','1187','1189','1200','1201','1202','1203','1204','1205','1206','1207','1210','1211','1212','1220','2003','2009','2022','2028','2042','2048','2062','2068','2082','2088','2102','2108','2122','2125','2128','2129','2134','2141','2144','2161','2182','2186','2222','2228','2242','2253','2262','2268','2302','2511','2512','2513','3180','3207','3208','4023','4024','4028','4029','4030','4031','4032','4033','4034','4036','4040','4041','4042','4043','4044','4062','4064','4066','4067','4068','4069','4070','4071','4092','5013','5014','5015','5016','5017','5018','6200','6201','6202','6203','6204','6205','6220','6221','6222','6223','6224','6225','6226','6234','6235','6240','6241','6242','6243','6244','6245','6246','6247','6249','6250','6251','6260','6261','6262','6263','6264','6265','6280','6281','6282','6283','6284','6285','6286','6287','6288','6289','6290','6291','6292','6293','6300','6301','6302','6303','6304','6305','6320','6321','6322','6323','6324','6325','6340','6342','6343','6344','6345','6346','6347','6348','6349','6360','6361','6362','6363','6364','6365','6366','6367','6368','6369','6371','6372','6373','6374','6375','6376','6377','6378','6379','6380','6381','6382','6383','6384','6385','6400','6401','6402','6403','6406','6407','6408','6420','6421','6422','6423','6424','6425','6426','6427','6428','6429','6430','6431','6432','6433','6434','6435','6436','6440','6441','6442','6443','6444','6445','6446','6447','6448','6449','6450','6451','6452','6453','6454','6455','6456','6457','6458','6459','6460','6470','6471','6472','6473','6474','6475','6476','6477','6478','6480','6481','6482','6483','6484','6485','6486','6487','6489','6490','6500','6501','6502','6504','6505','6506','6507','6508','6509','6510','6511','6512','6513','6514','6515','6520','6521','6522','6523','6524','6525','6526','6527','6528','6529','6530','6531','6550','6551','6552','6553','6554','6555','6556','6557','6558','6559','6560','6561','6562','6563','6564','6565','6567','6568','6569','6570','6572','6573','6574','7694','7993','9200','9201','9202','9203','9204','9205','9206','9208','9310','9320')

您应该创建一个临时表（请参阅临时表下），在该临时表上创建一个智能索引，将所有数据插入该临时表，然后在临时表和“bi_bunrui_syouhin_shop_day_jyutyuu”表之间进行内部连接。

如果性能是一个问题。您可以将 IN 替换为 Exists 并尝试此操作。但实际上它并不是使用 Exists 的确切方式。

前任：

Select * from Table1 where id exists (Select id from Table 2)

您可以将此作为参考。

SQL中EXISTS和IN的区别？

请让我知道结果。

谢谢。
