试图在 SQL 服务器中收集许多双引号之间的值当只有一对双引号时我设法收集。Ñ需要 T-SQL 来处理所有双引号，我不知道我是否会提取 1、2 或 30双引号之间的字符串。

我要处理的内容：

DECLARE @testData VARCHAR(250) = 'Task : "Testing Data" started "NOT" successfully. @ Status : "FAILED"' 

SELECT Substring(@testData, Charindex('"', @testData, 1) + 1, 
              Len(@testData) - Charindex('"', @testData) - 
              Charindex('"', Reverse(@testData))) AS [Output]; 

从上面的字符串，目标是得到：

• 测试数据
• 不是
• 失败的

OP 评论中发布的解决方案的其他变体，避免循环：

DECLARE @testData VARCHAR(250) = 'Task : "Testing Data" started "NOT" successfully. @ Status : "FAILED"'
DECLARE @delimeter VARCHAR(10) = '"';

;WITH
    tally AS --create sequence 1 to string Length
    (
        SELECT n = 1
        UNION ALL
        SELECT n +1
        FROM tally
        WHERE n <= LEN(@testData)
    ),
    cte AS
    (
        SELECT T.N , ROW_NUMBER() OVER ( ORDER BY T.N ) AS RN
        FROM tally AS T
        WHERE SUBSTRING(@testData, T.N, LEN(@delimeter)) = @delimeter
    )
SELECT REPLACE(SUBSTRING(@testData, COALESCE(R.N, LEN(@delimeter), 1),
                            L.N - COALESCE(R.N, LEN(@delimeter), 1)),@delimeter,'') AS part
FROM cte AS L
    LEFT JOIN cte AS R ON L.RN = R.RN+1
WHERE L.RN%2=0
