在Hive中支持AND子句

Question

我試圖在HIVE中執行以下查詢。

select plc 
 from processed p 
WHERE p.day=26 
  AND p.time_id = 41;

但是，我沒有結果。 但是，執行以下查詢后，我得到了有效的結果

select plc from processed p WHERE p.day=26 

我已經檢查了我的表，它包含對應於day = 26 and time_id = 41 。 Hive不支持多個AND子句嗎？

Answer 1

https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select顯示Hive確實支持AND子句。 特別是，他們的WHERE子句的第一個示例包括AND：

WHERE Clause

The WHERE condition is a boolean expression. For example, the following query returns only those sales records which have an amount greater than 10 from the US region. Hive supports a number of operators and UDFs in the WHERE clause:
SELECT * FROM sales WHERE amount > 10 AND region = "US"
