TSQL导致特定数量的列

Question

我正在尝试创建一个查询，该查询将按特定列数（例如4）分配行结果。请参见下面的屏幕截图。

Answer 1

这是表示问题，应在应用程序级别进行处理。 但是，如果您坚持：

SELECT column1 = MIN(CASE WHEN grp=1 THEN PartNumber+CHAR(13)+SerialNumber END)
      ,column2 = MIN(CASE WHEN grp=2 THEN PartNumber+CHAR(13)+SerialNumber END)
      ,column3 = MIN(CASE WHEN grp=3 THEN PartNumber+CHAR(13)+SerialNumber END)
      ,column4 = MIN(CASE WHEN grp=4 THEN PartNumber+CHAR(13)+SerialNumber END)
FROM (SELECT *,ROW_NUMBER() OVER(PARTITION BY rn ORDER BY rn) AS grp
      FROM (SELECT *,(ROW_NUMBER() OVER(ORDER BY 1/0)-1)/4 AS rn FROM tab)s)sub
GROUP BY rn;
