很多时候需要造数据，大量的插入数据，本文介绍了使用python批量生成insert语句的方法，需要的朋友们下面随着小编来一起学习学习吧
1.建表语句
2.目标insert语句
INSERT INTO `bidprcu_dic_a`( `DIC_ID`, `DIC_TYPE_CODE`, `DIC_TYPE_NAME`, `DATA_DIC_CODE`, `DATA_DIC_NAME`, `PRNT_CODE`, `SRT`, `MEMO`, `DATA_SOUC`, `RID`, `CRTER_ID`, `CRTER_NAME`, `CRTE_OPTINS_NO`, `CRTE_TIME`, `OPT_TIME`, `OPTER_ID`, `OPTER_NAME`, `OPTINS_NO`, `UPDT_TIME`, `INVD_FLAG`) VALUES ('1', 'cert_type', '证件类型', '11', '营业执照', '', NULL, '', NULL, '', NULL, NULL, NULL, '2020-07-07 11:30:39', NULL, NULL, NULL, NULL, '2020-07-07 11:30:39', '0');
3.方法一：python生成insert语句（字符串的拼接）
#生成的目标insert语句 """ INSERT INTO `bidprcu_dic_a`( `DIC_ID`, `DIC_TYPE_CODE`, `DIC_TYPE_NAME`, `DATA_DIC_CODE`, `DATA_DIC_NAME`, `PRNT_CODE`, `SRT`, `MEMO`, `DATA_SOUC`, `RID`, `CRTER_ID`, `CRTER_NAME`, `CRTE_OPTINS_NO`, `CRTE_TIME`, `OPT_TIME`, `OPTER_ID`, `OPTER_NAME`, `OPTINS_NO`, `UPDT_TIME`, `INVD_FLAG`) VALUES ('1', 'cert_type', '证件类型', '11', '营业执照', '', NULL, '', NULL, '', NULL, NULL, NULL, '2020-07-07 11:30:39', NULL, NULL, NULL, NULL, '2020-07-07 11:30:39', '0'); """ import uuid def create_uid(): return str(uuid.uuid1()) f =open('0524insert.txt','w') for i in range(1,3): DIC_ID=create_uid() DIC_TYPE_CODE = "cert_type" DIC_TYPE_NAME="证件类型" DATA_DIC_CODE="11" DATA_DIC_NAME="营业执照" PRNT_CODE="" SRT="NULL" CRTE_TIME="2020-07-07 11:30:39" UPDT_TIME="2020-07-07 11:30:39" INVD_FLAG="0" sql = "INSERT INTO bidprcu_dic_a(DIC_ID,DIC_TYPE_CODE,DIC_TYPE_NAME,DATA_DIC_CODE,DATA_DIC_NAME,PRNT_CODE,SRT,CRTE_TIME,UPDT_TIME,INVD_FLAG) " +"VALUES" +"(" +"'"+DIC_ID+"'"+",'"+DIC_TYPE_CODE+"'"+",'"+DIC_TYPE_NAME+"'"+",'"+DATA_DIC_CODE+"'"+",'"+DATA_DIC_NAME+"'"+",'"+PRNT_CODE+"'"+",'"+SRT+"'"+",'"+CRTE_TIME+"'"+",'"+UPDT_TIME+"'"+","+INVD_FLAG+""+")"+";" print(sql) f.write(sql) f.write("n") f.close()
最终生成数据
INSERT INTO bidprcu_dic_a(DIC_ID,DIC_TYPE_CODE,DIC_TYPE_NAME,DATA_DIC_CODE,DATA_DIC_NAME,PRNT_CODE,SRT,CRTE_TIME,UPDT_TIME,INVD_FLAG) VALUES('6b854a06-bcf9-11eb-8936-e454e805d291','cert_type','证件类型','11','营业执照','','NULL','2020-07-07 11:30:39','2020-07-07 11:30:39',0);
4.方法二：python生成insert语句（列表的方法，value生成后替换）
# 生成的目标insert语句 """ INSERT INTO `bidprcu_dic_a`( `DIC_ID`, `DIC_TYPE_CODE`, `DIC_TYPE_NAME`, `DATA_DIC_CODE`, `DATA_DIC_NAME`, `PRNT_CODE`, `SRT`, `MEMO`, `DATA_SOUC`, `RID`, `CRTER_ID`, `CRTER_NAME`, `CRTE_OPTINS_NO`, `CRTE_TIME`, `OPT_TIME`, `OPTER_ID`, `OPTER_NAME`, `OPTINS_NO`, `UPDT_TIME`, `INVD_FLAG`) VALUES ('1', 'cert_type', '证件类型', '11', '营业执照', '', NULL, '', NULL, '', NULL, NULL, NULL, '2020-07-07 11:30:39', NULL, NULL, NULL, NULL, '2020-07-07 11:30:39', '0'); """ import uuid def create_uid(): return str(uuid.uuid1()) f = open('0524insert.txt', 'w') value = [] for i in range(1, 3): list = [] DIC_ID = list.append(create_uid()) DIC_TYPE_CODE = list.append("cert_type") DIC_TYPE_NAME = list.append("证件类型") DATA_DIC_CODE = list.append(11) DATA_DIC_NAME = list.append("营业执照") PRNT_CODE = list.append("") SRT = list.append("NULL") CRTE_TIME = list.append("2020-07-07 11:30:39") UPDT_TIME = list.append("2020-07-07 11:30:39") INVD_FLAG = list.append(0) print(list) a = value.append(list) c = str(list) print(c) c = c.replace("[", "(").replace("]", ")") print(c) sql = "INSERT INTO bidprcu_dic_a(DIC_ID,DIC_TYPE_CODE,DIC_TYPE_NAME,DATA_DIC_CODE,DATA_DIC_NAME,PRNT_CODE,SRT,CRTE_TIME,UPDT_TIME,INVD_FLAG) " + "VALUES" + c + ";" print(sql) f.write(sql) f.write("n") f.close()
注意：
1.在使用时修改range的值即可
2.在生成大批量数据时，可以考虑多线程【后续学习后，优化该脚本】
