在sql中只获取字母数字行？

Question

我列有数据

CLARK
KING
MILLER
SMITH, $800 .00
JONES, $2975.00
SCOTT, $3000.00
ADAMS, $1100.00
FORD, $3000.00
ALLEN30  
WARD30  
MARTIN30  
BLAKE30  
TURNER30  
JAMES30  

我只想要字母数字行

SMITH, $800 .00
JONES, $2975.00
SCOTT, $3000.00
ADAMS, $1100.00
FORD, $3000.00

除了这行,所有行都应包括在内？

我怎么能得到这个？

Answer 1

你可以使用PATINDEX:

DECLARE @test table(col varchar(30));
INSERT INTO @test
   SELECT * FROM (SELECT 'CLARK' UNION ALL SELECT 'KING' UNION ALL SELECT 'MILLER' UNION ALL SELECT 'SMITH, $800 .00' UNION ALL SELECT 'JONES, $2975.00' UNION ALL SELECT 'SCOTT, $3000.00' UNION ALL SELECT 'ADAMS, $1100.00' UNION ALL SELECT 'FORD, $3000.00' UNION ALL SELECT 'ALLEN30' UNION ALL SELECT 'WARD30' UNION ALL SELECT 'MARTIN30' UNION ALL SELECT 'BLAKE30' UNION ALL SELECT 'TURNER30' UNION ALL SELECT 'JAMES30')AS T(Spalte)

Patindex返回指定表达式中第一次出现模式的起始位置.由于我使用的模式与任何非字母数字(^通配符 - 字符)匹配,因此仅返回仅包含字母数字字符(+空格)的记录:

SELECT col 
FROM   @test
WHERE  PATINDEX('%[^a-zA-Z0-9 ]%',col) = 0

结果:

CLARK
KING
MILLER
ALLEN30
WARD30
MARTIN30
BLAKE30
TURNER30
JAMES30
