在Sql Server中不使用order by選擇行作為第一行

Question

例：

id  name  agreement
32  fahid   52
43  nahid   51
31  zal     52

想通過協議選擇，但我想保持給定id頂部，如果我使用order by那么總是id被排序。 如果我搜索agreement=52和id=32然后預期的結果：

32 fahid 52
31 fahid 52

Answer 1

您可以order by id,agreement使用多個字段

Answer 2

嘗試這個

DECLARE @id INT
DECLARE @agreement INT

SET @id = 32
SET @agreement = 52

SELECT [id]
, (SELECT [name] FROM Table1 WHERE [id] = @id) AS [name]
, [agreement] FROM Table1 
WHERE [agreement] = @agreement

SQL FIDDLE DEMO

OUTPUT

id  name    agreement
32  fahid   52
31  fahid   52

Answer 3

在mysql中使用LIMIT

MySQL語法

SELECT column_name(s)FROM table_name WHERE (condition) LIMIT number;

例

SELECT * FROM Persons WHERE agreement=52 LIMIT 5;

Oracle語法

SELECT column_name(s)FROM table_name WHERE ROWNUM <= number; 

例

SELECT * FROM Persons WHERE ROWNUM <=5;
