MYSQL团体在Sybase ASE中具有相当的成分。
原标题:MYSQL group_concat equivalent in Sybase ASE?

在Sybase ASE与MYSQL的团体之间是否有类似的功能?

你们必须建立一个储存的程序。

问题回答

更好但又能形成一种 cur子,在可能进入存储程序时处理一行。 假设曲线按条款对数据进行分类,然后通过诸如团体_concat = 团体_concat + Field等表达方式整理数据。

你有权力!

好夜。

这种问询将混入“栏号”一栏中的几行,你可以改变空间分辨器的特性,使之与宇宙体、闪lash等相。 在这种情况下,我选择空间,因为只有三米才能在产出的开始和结束时从空间中抽走。

SELECT column_to_concat
INTO #table_temp
FROM table

DECLARE @data VARCHAR(100)

UPDATE #table_temp
SET @data = @data +     + column_to_concat

SELECT LTRIM(RTRIM(@data))

DROP TABLE #table_temp

您可以利用LIST的职能:

SELECT continent,
LIST (country,  , ) as countries_in_continent
FROM world
GROUP BY continent
