MSSQL、ORALCE批量新增，后者太强

MSSQL：131072条数据，7秒。
代码：

CREATE TABLE tempTable(bigint varchar(30),item_name varchar(30)); 
INSERT INTO tempTable VALUES (1, 'Hammer') 
DECLARE @counter int;
SET @counter = 1 ;
WHILE(@counter <= 17) 
BEGIN 
        INSERT INTO tempTable (bigint, item_name) 
                (SELECT bigint + (SELECT COUNT(*) FROM tempTable), 'Hammer' FROM tempTable) 
        SET @counter = @counter + 1
END 
SELECT * FROM tempTable 
--DROP TABLE tempTable

结果：
