在密码附近获取错误的语法错误

Answer 1

根据我发现的内容，如果您的sql语句具有参数，则应像这样修改代码：

ownerpass="abcdef"
owner="yrdy"
sql_login = (
"DECLARE @sql AS NVARCHAR(MAX);"
"DECLARE @Databaseowner sysname = ?;"
"DECLARE @Databaseownerpass sysname = ?;"
"SET @sql = N'if not exists (select * from sys.sql_logins where name = @Databaseowner )'  + N' CREATE LOGIN ' + QUOTENAME(@Databaseowner) + N''' WITH PASSWORD = ' + QUOTENAME(@Databaseownerpass, '''') + N';';"
"EXEC sp_executesql @sql,N'@Databaseowner sysname', N'@Databaseownerpass sysname', @Databaseowner = @Databaseowner, @Databaseownerpass = @Databaseownerpass;")
cursor.execute(sql_login, (owner,ownerpass))

参考：(Python) cursor.execute(sql)

希望这会有所帮助。

首先，生成有效的T-SQL语句。使用CREATE LOGIN和sp_executesql时出现错误。

ownerpass = "abcdef"
owner = "yrdy"
sql_login = (
    "DECLARE @sql AS NVARCHAR(MAX);"
    "DECLARE @Databaseowner sysname = ?;"
    "DECLARE @Databaseownerpass sysname = ?;"
    "SET @sql = 
        N'if not exists (select * from sys.sql_logins where name = @Databaseowner )'  + 
        N' CREATE LOGIN ' + QUOTENAME(@Databaseowner) + 
        N' WITH PASSWORD = ' + QUOTENAME(@Databaseownerpass, '''') + N';';"
    "EXEC sp_executesql @sql, N'@Databaseowner sysname, @Databaseownerpass sysname', @Databaseowner, @Databaseownerpass;"
)   

然后，如果您使用?作为占位符，请按以下方式执行脚本：

cursor.execute(sql_login, (owner, ownerpass))

Answer 3

“ SET @sql = N'如果不存在（从sys.sql_logins中选择*，其中name = @Databaseowner）'+ N'CREATE LOGIN'+ QUOTENAME（@Databaseowner）+ N'''WITH PASSWORD ='+ QUOTENAME （@Databaseownerpass，''''）+ N';';“

如何在上面的行中添加check_policy = off？
