通過使用SQL將varchars轉換爲兩點十進制值

Question

我有一個帶有下面的金額列表的平面文件，可以請告訴我，我怎麼能把這個金額列表變成兩點十進制值，如1234567.80與{，A，H，E，C，I，F通過使用SQL？

12345678{ 
00484326A 
00000210H 
00000185A 
00000077E 
00000833C 
00000255I 
00000077E 
00000039F 
00000088A 
00000000F 
00000000A 
00000100{ 

謝謝你，

Answer 1

嘗試以此爲with this SQLfiddle。不漂亮，但它的工作原理

SELECT 
    CAST(
     CONCAT(SUBSTRING(test_value,1, LENGTH(test_value) -2), 
       '.', 
       SUBSTRING(test_value, LENGTH(test_value) -1, 1)) 
    AS DECIMAL(7,1)) 
FROM TEST 
WHERE SUBSTRING(test_value, LENGTH(test_value)) = 'A' 
|| SUBSTRING(test_value, LENGTH(test_value)) = 'H' 
-- keep adding above line for the rest of the ending characters you want 

Answer 2

我寫了這是一個功能，因爲我覺得它更容易比內聯代碼爲：

create function dbo.convert_amount_str (@amount_str varchar(50)) 
returns money 
as 
begin 
declare @char_index int 
declare @amount money 
declare @char varchar(50) 
declare @decimal money 

-- Match the first non-numeric character 
select @char_index = PATINDEX('%[^0-9]%', @amount_str) 

-- Get the numeric characters into a numeric variable 
select @amount = convert(money, SUBSTRING(@amount_str, 0, @char_index)) 

-- Get the non-numeric character (will work for multiple characters) 
select @char = SUBSTRING(@amount_str, @char_index, (len(@amount_str) - @char_index) + 1) 

-- Convert the non-numeric characters into decimal amounts 
select @decimal = case @char 
    when 'A' then .8 -- whatever this should equate to 
    when 'H' then .7 -- whatever this should equate to 
    -- output for remaining characters 
    end 

return @amount + @decimal 
end 

就用這樣的：

select dbo.convert_amount_str('00484326A') 

或者，更可能的是，引用任何包含數字字符串值的列。
