SELECT dbo.ConcatenateStrings(ColumnName) AS AggregatedString FROM YourTable WHERE SomeCondition; 总结 在SQL Server 旧版中,字符串聚合可以通过FOR XML PATH或自定义聚合函数实现。尽管这些方法可能不如新版本中的STRING_AGG函数简洁高效,但它们仍然能够有效地处理字符串聚合的需求。选择合适的方法取决于具体的应用...
It requires a minimum of two input values; otherwise, CONCAT raises an error. CONCAT implicitly converts all arguments to string types before concatenation. CONCAT implicitly converts null values to empty strings. If CONCAT receives arguments with all NULL values, it returns an empty string of ...

CONCATcan be executed remotely on a linked server running SQL Server 2012 (11.x) and later versions. For older linked servers, theCONCAToperation will happen locally, after the linked server returns the non-concatenated values. Examples
