python读取excel表格生成sql语句 第一版

由于单位设计数据库表·，都用sql.不知道什么原因不用 powerdesign或者ermaster工具，建表很痛苦  作为程序猿当然要想办法解决，用Python写一个程序解决

需要用到 xlrd linux下 sudo pip install xlrd

主要是适用于db2数据库

excel 表结构 其中 number是不正确的字段类型 不知道同事为啥这么设置。这里程序里有纠错，这个程序就是将sql语句拼好。

import xlrd
import re


data = xlrd.open_workbook("1.xlsx")
table = data.sheets()[0]

temp = table.row_values(0)[0]

tableName = re.findall("[A-Z].*w+", temp)[0]

nrows = table.nrows
#print nrows
sql = "create table " + tableName + "(

for rownum in range(2, nrows):
    row = table.row_values(rownum)

    if row and rownum != (nrows - 1):

        if row[1] == "ID":
            temp = float(row[3])
            sql += row[1] + " " + row[2] + "(" + str(int(temp)) + ") " + "PRIMARY KEY,

        else:
