Question

我在MySQLWorkbench中有以下查询

    Select * from table where col1 = "A" and col2 = "a"   
    Select * from table where col1 = "B" and col2 = "b"  
    Select * from table where col1 = "C" and col2 = "c"  
    Select * from table where col1 = "D" and col2 = "d"  
    Select * from table where col1 = "E" and col2 = "e"

我可以将这些查询放入一个像这样的查询

Select * from table where col1 = <value1> and col2 =<value2>

从文件（或某处）读取值并将其分配给查询并运行。

我认为，我可以用以下格式存储价值

A,a
B,b
C,b
D,d
E,e

Answer 1

你的意思是：

select
    *
from
    table
where
    (col1 ='A' and col2 = 'a')
    OR (col1= 'B' and col2 = 'b')
    OR (col1 = 'C' and col2 = 'c')

Answer 2

你可以使用：

Select 
       * 
from 
       table 
where 
       col1 IN ('A','B','C','D','E') and col2=LOWER(col1);

Answer 3

就像我在评论中建议的那样，您可以使用IN运算符：您可以阅读有关here的更多信息。

SELECT * FROM table
WHERE col1 IN ("A", "B", "C", "D", "E") and col2 IN ("a", "b", "c", "d", "e")

Answer 4

你想要一些你传递参数的东西吗？

如果是这样，以下程序将起作用

.title
