How can i get value of column based on values of two other columns in Oracle Using C#?

Question

I have a table in Oracle which saves the percentage of tax based on different salaries, eg Tax is 5% if Salary is >5000 and Salary is < 10000. Here is the structure of my table:

CREATE TABLE TaxDetailTable
   (    MinSalary FLOAT(126), 
    MaxSalary FLOAT(126), 
    TAX_PERCENT FLOAT(126)
   )

now i want to get that percentage value based on the salary i input using C#. Right now i am just comparing the salary i have provided to the input values, but i want some efficient way to do this.Can someone help me? My query is:

Select Tax_Percent From TaxDetailTable Where MinSal >= inputSal And MaxSal <= inputSal

Answer 1

这是一个更好的查询，可能会返回数据：

Select tax_percent From taxDetailTable Where inputSal Between minSal And maxSal
