問題描述

我想在指向其他表中 pk 的表中插入幾百行.我一直在嘗試使用 while 循環在表中插入多條記錄.我實際上是在設置我的測試數據.

I want to insert couple of hundred rows into a table that points to pk in other table. I have been trying to use while loops for inserting multiple records in the table. I am actually setting up my test data.

這就是我正在做的:

declare @count int;
set @count = 4018;

while @count <= 5040 
begin
    INSERT INTO [MY_TABLE]
               ([pk_from_other_table]
               ,[..]
               ,[...]
               ,[..]
               ,[..]
               ,[...]
               ,[...]
               ,[..])
        select
               (pk_from_other_table,
               ,[..]
               ,[...]
               ,[..]
               ,[..]
               ,[...]
               ,[...]
               ,[..])
    @count = @count + 1;
end

但這似乎不起作用！任何人都可以幫忙...我想做的就是插入記錄數 = 主表中存在的記錄數.

but this does not seems to work ! can anyone help please... all I want to do is insert number of records = number of records that exist in primary table.

?關于如何實現這一目標的任何想法?

? any idea on how can I achieve this ?

我要么在計數附近得到錯誤的語法

I either get incorrect sytax near count

或

消息 102，級別 15，狀態 1，第 17 行',' 附近的語法不正確.

Msg 102, Level 15, State 1, Line 17 Incorrect syntax near ','.

推薦答案

您當前的語法問題是 @count = @count + 1; 需要 set @count =@count + 1.

Your current syntax problem is with the @count = @count + 1; which needs to be set @count = @count + 1.

但是……

不需要循環.你可以直接做一個大的插入，比如:

There is no need for a loop. You can simply do one big insert directly, like:

insert into your_table (fk_col, other_col1, other_col2)
select pk_col, 'something', 'something else' 
from your_other_table

如果需要，可以在上面添加where子句.

If you need to, you can add a where clause to the above.
