python連接數據庫SQLServer

連接數據庫的幾種方式

• python odbc
• pymssql

whl如何安裝

whl類似于離線安裝包，需要使用pip安裝。
pip install指令就可以安裝。

pymssql連接SQL Server讀取中文程序“UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2: ordinal not in range(128)”

原因
python默認使用unicode編碼，編碼不一致問題導致。
解決辦法
找到python安裝目錄下Lib目錄，site.py文件，找到setencoding函數
if 0:
# Enable to support locale aware default string encodings.
修改"if 0"為"if 1"就可以了

    def setencoding():
    """Set the string encoding used by the Unicode implementation.  The
    default is 'ascii', but if you're willing to experiment, you can
    change this."""
    encoding = "ascii" # Default value set by _PyUnicode_Init()
    if 0:
        # Enable to support locale aware default string encodings.
        import locale
        loc = locale.getdefaultlocale()
        if loc[1]:
            encoding = loc[1]
    if 0:
        # Enable to switch off string to Unicode coercion and implicit
        # Unicode to string conversion.
        encoding = "undefined"
    if encoding != "ascii":
        # On Non-Unicode builds this will raise an AttributeError...
        sys.setdefaultencoding(encoding) # Needs Python Unicode build !
