Question

我有类似下面的SQL查询：

SELECT COUNT(*) TheseMatch, 
(SELECT COUNT(*) FROM [MyTable]) ThisIsMyTotal
FROM [MyTable]  
WHERE MyCondition = 'MyCondition'

我正在尝试为此添加一个字符串文字，它将在同一个返回的行上提供。我一直在尝试这个：

SELECT 'THIS IS MY STRING' as Note,
SELECT COUNT(*) TheseMatch, 
(SELECT COUNT(*) FROM [MyTable]) ThisIsMyTotal
FROM [MyTable]  
WHERE MyCondition = 'MyCondition'

但是这会返回语法错误。显式指定字符串文字的正确方法是什么，并将其添加到结果中？

TIA！

Answer 1

正确的语法类似于

SELECT 'THIS IS MY STRING' as Note,
     COUNT(*) TheseMatch, 
     (SELECT COUNT(*) FROM [MyTable]) ThisIsMyTotal
FROM [MyTable]  
WHERE MyCondition = 'MyCondition'

Answer 2

SELECT 'THIS IS MY STRING' as Note,   
SELECT COUNT(*) TheseMatch, 
(SELECT COUNT(*) FROM Banks) ThisIsMyTotal
FROM Banks  
WHERE Banks.Name = 'MyCondition'

将字符串文字添加到SQL结果
