title: What data type to use for some number, date and phone number in c#?
body: <p>Hi I have an application in asp.net which contains four text fields for number, amount, date and telephone. When clicked on a button these values has to be saved into Oracle Database. Used procedures to save these values. In oracle database datatypes are, number column is of type number, amount column is of type number, date column is of type datetime and phonenumber is of type number. I am using validations for all four text fields so that these values are in proper format. In my code I am passing number, date, telephone as string and amount as double. Is this the best pratice ? If not can any one suggest me the data types I have to use for 4 fields (number, amount, date and telephone number) ?</p>
