Question

我正在尝试将sql select查询的结果写入xls文件。下面是代码：

RowNum = 8
sql = """select * from #table"""
cursor = self.db_conn.cursor()
cursor.execute(sql)
rb = open_workbook(settings.FILE_NAME,formatting_info=True)
wb = copy(rb)

sheet1 = wb.get_sheet('Sheet 1')

for row in cursor.fetchall():
    sheet1.write(RowNum, 0, row) # row, column, value
    RowNum = RowNum + 1

wb.save(settings.FILE_NAME_New)

但是出现以下错误：

sheet1.write(RowNum, 0, row) # row, column, value
  File "python-3.4.3\lib\xlwt\Worksheet.py", line 1088, in write
    self.row(r).write(c, label, style)
  File "python-3.4.3\lib\xlwt\Row.py", line 254, in write
    raise Exception("Unexpected data type %r" % type(label))
Exception: Unexpected data type <class 'pyodbc.Row'>

我哪里出错了？

Answer 1

row不是文字值，而是pyodbc.Row。根据所需行的哪一列的值，使用以下命令：

column_number = 0
sheet1.write(RowNum, 0, row[column_number]) # row, column, value

Answer 2

您需要提及column_number，您正在尝试在文件而不是特定列上写入pyodbc对象。

RowNum = 8
sql = """select * from #table"""
cursor = self.db_conn.cursor()
cursor.execute(sql)
rb = open_workbook(settings.FILE_NAME,formatting_info=True)
wb = copy(rb)

sheet1 = wb.get_sheet('Sheet 1')
column_no = 0
for row in cursor.fetchall():
    sheet1.write(RowNum, 0, row[column_no]) # change this line
    RowNum = RowNum + 1

wb.save(settings.FILE_NAME_New)

使用xlwt，将SQL选择查询结果插入到xls中的单元格
