Mysql 在块中轮询数据

我有如下的存储过程

CREATE procedure [dbo].[Poll_EDI834_5010]
AS
BEGIN
select
    Header.ST01,
    Header.ST02,
    Header.ST03 ,

它大约有10万张唱片。我需要将数据分块获取。比如先10000，然后再10000…我需要在存储过程中更改什么以获得数据块。

在数据中需要某种索引、序列列或可排序ID列。让我们称之为keyColumn。然后，您需要将可能的最大行数拆分为每次迭代所需的行数。我不知道你的模式，所以让我们像你在问题中说的那样使用10000行

然后，您需要在每次迭代中选择尽可能多的行并执行。。。不管你想做什么

SELECT @minID = Min(keyColumn) FROM table WHERE condition
SELECT @maxID = Max(keyColumn) FROM table WHERE condition
SELECT @potentialRows = 10000

WHILE @minID < @maxID
BEGIN
    SET @breakID = @minID + @potentialRows
    SELECT columns FROM table WITH (NOLOCK, ...)
    WHERE condition AND keyColumn BETWEEN @minID AND @breakID

    -- Do what you want with the selected rows here...

    SET @minID = @breakID + 1
END

如果keyColumn值稀疏，则必须更改潜在行计算。

这是MySql还是SQL Server？FOR语句不是有效的TSQL。您必须发布代码和错误消息；我看不到你的屏幕。
