插入表格

INSERT INTO 將附加到表或分割槽，保持現有資料不變。

    INSERT INTO table yourTargetTable SELECT * FROM yourSourceTable;

如果表被分割槽，那麼我們可以以靜態方式插入到該特定分割槽中，如下所示。

    INSERT INTO TABLE yourTargetTable PARTITION (state=CA, city=LIVERMORE) 
    select * FROM yourSourceTable;

如果表被分割槽，那麼我們可以動態方式插入到該特定分割槽，如下所示。要執行動態分割槽插入，我們必須在下面的屬性下面設定。

    Dynamic Partition inserts are disabled by default. These are the relevant configuration properties for dynamic partition inserts:
    SET hive.exec.dynamic.partition=true;
    SET hive.exec.dynamic.partition.mode=non-strict

    INSERT INTO TABLE yourTargetTable PARTITION (state=CA, city=LIVERMORE) (date,time)
    select * FROM yourSourceTable;

從表中多次插入。

Hive 擴充套件（多個插入）：

    FROM table_name

    INSERT OVERWRITE TABLE table_one SELECT table_name.column_one,table_name.column_two

    INSERT OVERWRITE TABLE table_two SELECT table_name.column_two WHERE table_name.column_one == 'something'
