What is Tabular expression statement?
当我尝试使用 Azure 数据资源管理器时，经常使用词：Tabular expression statement。什么是 Tabular expression statement？它与 sql 查询语言有何不同？
首先，Tabular expression statements定义在kusto query language中。 Kusto query language is totally different from sql query. You can refer to this doc 差异。
对于Tabular expression statement，定义为here。以下是它的一些要点：
The tabular expression statement is what people usually have in mind
when they talk about queries. This statement usually appears last in
the statement list, and both its input and its output consists of
tables or tabular data sets.
Kusto uses a data flow model for the tabular expression statement. The
typical structure of a tabular expression statement is a composition
of tabular data sources (such as Kusto tables), tabular data operators
(such as filters and projections), and potentially rendering
operators.
看起来像这样：
source1 | operator1 | operator2 | renderInstruction
详细示例如下：
Logs | where Timestamp > ago(1d) | count
