GO附近语法不正确

Question

我连接了很多sql语句，并且遇到以下错误。 “靠近GO的语法不正确”和“附近的语法错误” - 看来，当我删除尾部空格以及走后的空格和空格，然后按CTRL + Z放回GO时，这会使错误消失？其相当奇怪的 为什么？ 我怎么能在Python代码它，谢谢

END TRY 
BEGIN CATCH 
print ERROR_MESSAGE() 
END CATCH 
GO

正如评论已经提到，GO不是SQL语法，而Management Studio中一批分隔符的一部分。

你可以通过两种方式绕过它，使用Subprocess来调用SqlCmd，或者在Python中剪切脚本。如果您不关心查询结果，那么Subprocess + SqlCmd只会真正适用于您，因为您需要解析控制台输出以获取这些结果。

我需要从SSMS产生在过去的脚本，并创建了以下功能的结果建立数据库（更新，因为我现在有一个更好的版本留下的评论中）：

def partition_script(sql_script: str) -> list: 
    """ Function will take the string provided as parameter and cut it on every line that contains only a "GO" string. 
     Contents of the script are also checked for commented GO's, these are removed from the comment if found. 
     If a GO was left in a multi-line comment, 
     the cutting step would generate invalid code missing a multi-line comment marker in each part. 
    :param sql_script: str 
    :return: list 
    """ 
    # Regex for finding GO's that are the only entry in a line 
    find_go = re.compile(r'^\s*GO\s*$', re.IGNORECASE | re.MULTILINE) 
    # Regex to find multi-line comments 
    find_comments = re.compile(r'/\*.*?\*/', flags=re.DOTALL) 

    # Get a list of multi-line comments that also contain lines with only GO 
    go_check = [comment for comment in find_comments.findall(sql_script) if find_go.search(comment)] 
    for comment in go_check: 
     # Change the 'GO' entry to '-- GO', making it invisible for the cutting step 
     sql_script = sql_script.replace(comment, re.sub(find_go, '-- GO', comment)) 

    # Removing single line comments, uncomment if needed 
    # file_content = re.sub(r'--.*$', '', file_content, flags=re.MULTILINE) 

    # Returning everything besides empty strings 
    return [part for part in find_go.split(sql_script) if part != ''] 

使用此功能，您可以运行包含GO这样的脚本：

import pymssql 

    conn = pymssql.connect(server, user, password, "tempdb") 
    cursor = conn.cursor() 
    for part in partition_script(your_script): 
     cursor.execute(part) 

    conn.close() 

我希望这有助于。
