Excel到PostgreSQL使用Python

我是Python的新手，我试图将excel直接导出到没有CSV文件的postgreSQL中。

我不知道是否可能。

我一直运行到错误'column "daily_date" is of type date but expression is of type numeric' 。

 import psycopg2 import xlrd book = xlrd.open_workbook("pytest.xlsx") sheet = book.sheet_by_name("Source") database = psycopg2.connect (database = "RunP", user="postgres", password="", host="localhost", port="5432") cursor = database.cursor() query = """INSERT INTO orders (Daily_Date, Days, First, Second, Leader) VALUES (%s, %s, %s, %s, %s)""" for r in range(1, sheet.nrows): Daily_Date = sheet.cell(r,0).value Days = sheet.cell(r,1).value First = sheet.cell(r,2).value Second = sheet.cell(r,3).value Leader = sheet.cell(r,4).value values = (Daily_Date, Days, First, Second, Leader) cursor.execute(query, values) cursor.close() database.commit() database.close() print "" print "" columns = str(sheet.ncols) rows = str(sheet.nrows) print "I just imported Excel into postgreSQL" 

Answer 1

Excel将date时间存储为数字。 您可以使用xlrd.xldate.xldate_as_datetime来转换：

  Daily_Date = xlrd.xldate.xldate_as_datetime(sheet.cell(r,0).value,book.datemode)
