Question

我正在创建一个易失性表并尝试向表中插入行。我可以上传一行如下......

create volatile table Example
(
    ProductID VARCHAR(15),
    Price DECIMAL (15,2)
)
on commit preserve rows;
et;

INSERT INTO Example
Values
('Steve',4);

然而，当我尝试上传多个时，我收到错误：

“语法错误：预期在'）'和'，'之间。”

INSERT INTO Example
Values
('Steve',4),
('James',8);

Answer 1

正如Gordon所说，Teradata不支持多行的VALUES（由于缺少FROM，UNION ALL将失败。

您可以改为使用多语句请求（MSR）：

INSERT INTO Example Values('Steve',4)
;INSERT INTO Example Values('James',8)
;

如果是BTEQ作业，则在最后一个分号后将插入作为一个块提交（当一个新命令从同一行开始时它是MSR的一部分）。在SQL Assistant或Studio中，您必须使用F9而不是F5提交。

Answer 2

我不认为Teradata支持多行class GameScene : SKScene { var timer: NSTimer! override func didMoveToView(view: SKView) { timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector(), userInfo: nil, repeats: false) } } class Viewcontroller : UIViewController { override func viewDidLoad() { super.viewDidLoad() var skView = self.view as! SKView let gameScene = GameScene() skView.presentScene(gameScene) gameScene.timer = //whatever } }语法。只需使用values：

select

Answer 3

CTE语法（有效）：

insert into target_table1 (col1, col2)
with cte as (select 1 col1)
select 'value1', 'value2' from cte
union all
select 'value1a', 'value2a' from cte
;

CTE语法在Teradata中不起作用（错误：预期为“）”和“插入”关键字之间的某项）

with cte as (select 1 col1)
insert into target_table1 (col1, col2)
select 'value1', 'value2' from cte
union all
select 'value1a', 'value2a' from cte
;

Answer 4

create table dummy (dumcol varchar(1));

INSERT INTO Student
    (Name, Maths, Science, English)
SELECT 'Tilak', 90, 40, 60 from dummy union 
SELECT  'Raj', 30, 20, 10 from dummy
;

Answer 5

我通过RECURSIVE找到了解决方案。它是这样的： -

INSERT INTO table (col1, col2)
with recursive table (col1, col2) as 
(select 'val1','val2' from table)  -- 1
select 'val1','val2' from table    -- 2
union all select 'val3','val4' from table
union all select 'val5','val6' from table;

第1行的数据未插入（但您需要此行）。从第2行开始，为val1，val2等输入的数据将插入到相应的列中。使用尽可能多的UNION ALLs＆＃39;要插入的行数。希望这会有所帮助：）

Answer 6

至少在我们的Teradata版本中，我们无法使用带有CTE的insert语句。相反，找一个真正的桌子（最好是小的）并做一个前1。

Insert Into OtherRealTable(x, y)
Select top 1
   'x' as x, 
   'y' as y
FROM RealTable

Answer 7

是的，您可以尝试一下。

INSERT INTO  Student 
  SELECT (Name, Maths, Science, English)  FROM JSON_Table 
        (ON (SELECT 1 id,cast('{"DataSet" : [
{"s":"m", "Name":"Tilak", "Maths":"90","Science":"40", "English":"60" },   
{"s":"m", "Name":"Raj", "Maths":"30","Science":"20", "English":"10" }
]
}' AS json ) jsonCol)
USING rowexpr('$.DataSet[*]')
colexpr('[{"jsonpath":"$.s","type":"CHAR(1)"},{"jsonpath":"$.Name","type":"VARCHAR(30)"}, {"jsonpath":"$.Maths","type":"INTEGER"}, {"jsonpath":"$.Science","type":"INTEGER"}, {"jsonpath":"$.English","type":"INTEGER"}]')
) AS JT(id,State,Name, Maths, Science, English)
