SQL Server - COUNT函数 - 可能与GROUP BY冲突？

Question

我在视图中使用以下代码，以便从表中提取一些数据：

SELECT

esli.fDocumentGID AS DocGID,
count(esli.LineNumber) X,
esli.GID AS LineGID,
esli.LineNumber AS ItemNum,

关键在于，即使我使用COUNT函数来计算文档行中有多少行，我总是在两行上得到1。不应该是结果2？我有什么遗漏或者没有以正确的方式使用过吗？

我认为它可能与GROUP BY条款有关，我没有正确使用它。

输出

DocGID                                  X   LineGID
5236BD3F-668E-4B1E-9B3D-34E77B895FF1    1   2721B7D7-7AB6-44EC-BADB-F5F936DEDFE9
5236BD3F-668E-4B1E-9B3D-34E77B895FF1    1   70D9D3AE-5691-42C5-8212-EE7E079FC17F

谢谢！

您在Group By子句中使用esli.GID，这对于行来说是不同的。
