存储过程中参数的动态数据类型

Question

I have a table Customer which has 3 columns

CCode varchar(100),
CName varchar(200),
Address varchar(500)

I want to create a procedure to insert data, I want that datatype of parameter should be selected automatically according to the table columns, so that for example if i need to change the CCode datatype from varchar to int in the table, it should be automatically change the datatype of parameter CCode .

Like oracle provide % type attribute, as you can see in below link:

https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/type_attribute.htm

I want same functionality as mentioned in above link.

Answer 1

SQL Server doesn't support the %TYPE functionality that Oracle has. You could use sql_variant , but that has drawbacks around knowing what type it's supposed to be. You could also try having a variety of optional parameters, and then using whichever is actually going to be used in your situation.
