Oracle库数据迁移到MySQL库

shlboliqiao

通过Python脚本进行两个库数据的迁移
刚接触PY，希望大家多指教

[Python] 纯文本查看 复制代码

from db_conf.dbtemplate import OracleTemplate
from db_conf.dbtemplate import MysqlTemplate
from entity.NormalTable import Prod_Inst


def batch_prod_qsub():
    orcal_conn = OracleTemplate('NEWCRM_ASSET')
    mysql_conn = MysqlTemplate('cusdb')
    sql_prod ="select * from data_adm.cgtmp_prod_inst_attr2019121303"

    orcal_conn.execute(sql_prod)
    ora_result1 = orcal_conn.fetchall(True)
    #print(ora_result1)
    ora_c1 = len(ora_result1)

    for or1 in range(ora_c1):
        ora_result2 =ora_result1[or1]
        #print(ora_result2)
        sql_header = " INSERT INTO prod_inst_attr( "
        sql_fields = ""
        sql_tail = " ) VALUES( "
        val_fields = ""
        val_list = []
        # print(c1)
        for c1 in ora_result2:
            if sql_fields == "":
                sql_fields = c1
                sql_val = " %s "
                val_list.append(ora_result2[c1])
            else:
                sql_fields += " , " + str(c1)
                sql_val += " , %s "
                val_list.append(ora_result2[c1])

        sql_text = sql_header + sql_fields + sql_tail + sql_val + " ) "
        #print(val_list)
        mysql_conn.execute(sql_text,val_list)
    orcal_conn.commit()
    orcal_conn.close()
    mysql_conn.commit()
    mysql_conn.close()
batch_prod_qsub()
