我有此存储过程，并希望将其修改为在SQL中重建多个索引

CREATE PROCEDURE RebuildIndexes
AS
BEGIN
    -- 声明变量
    DECLARE @IndexName NVARCHAR(100)
    DECLARE @TableName NVARCHAR(100)
    DECLARE @SQL NVARCHAR(MAX)

    -- 创建游标
    DECLARE IndexCursor CURSOR FOR
    SELECT name, object_name(object_id) 
    FROM sys.indexes 
    WHERE type = 2 -- 非聚集索引

    -- 打开游标
    OPEN IndexCursor

    -- 获取第一个索引
    FETCH NEXT FROM IndexCursor INTO @IndexName, @TableName

    -- 循环处理索引
    WHILE @@FETCH_STATUS = 0
    BEGIN
        -- 构建重建索引的SQL语句
        SET @SQL = 'ALTER INDEX ' + QUOTENAME(@IndexName) + ' ON ' + QUOTENAME(@TableName) + ' REBUILD'

        -- 执行重建索引的SQL语句
        EXEC(@SQL)

        -- 获取下一个索引
        FETCH NEXT FROM IndexCursor INTO @IndexName, @TableName
    END

    -- 关闭游标
    CLOSE IndexCursor
    DEALLOCATE IndexCursor
END
