Answer 1

根据我的发现，如果你的 sql 语句有参数，你应该像这样修改你的代码：

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))

首先，生成有效的 T-SQL 语句。使用 CREATE LOGIN and 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，请按如下方式执行您的脚本：

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

Answer 3

"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';';"

如何在上面的行中添加 check_policy= off？
