我需要一个与 SQL Server 中的 Oracle WM_CONCAT
类似的函数,它返回一个逗号分隔的列表,其中包含您将其作为参数传递的任何字段.例如,在 Oracle 中,
I need a similar function to Oracle WM_CONCAT
in SQL Server, which returns a comma separated list of whatever field you pass it as argument. For example, in Oracle,
select WM_CONCAT(first_name) from employee where state='CA'
返回约翰、吉姆、鲍勃".
returns "John, Jim, Bob".
如何在 SQL Server 中执行此操作?
How can I do this in SQL Server?
谢谢
在SQL Server 2017中增加了STRING_AGG函数
In SQL Server 2017 STRING_AGG function has been added
SELECT t.name as TableName
,STRING_AGG(c.name, ';') AS FieldList
FROM sys.tables t
JOIN sys.columns c
ON t.object_id = c.object_id
GROUP BY t.name;
