SQL从3列返回唯一数据并显示多少次

Question

我有的：

SELECT SGFORM.FFORMDESC, SGFORM.FPAPERNAME, SGFORM.FPAPERDESC
FROM SGFORM
Group by SGFORM.FPAPERNAME, SGFORM.FPAPERDESC, SGFORM.FFORMDESC
Having Count (*) > 0;

这给了我唯一项目的列表，但没有计数。

Answer 1

SELECT SGFORM.FFORMDESC, SGFORM.FPAPERNAME, SGFORM.FPAPERDESC, COUNT(*)
FROM SGFORM 
Group by SGFORM.FPAPERNAME, SGFORM.FPAPERDESC, SGFORM.FFORMDESC 
Having Count (*) > 0
