Application Security Testing: An Integral Part of DevOps

Combining Columns of Different Types

I am doing a select from a table where I want to combine two fields. Specifically, I have the StreetNumber and the StreetName stored separately. I would like to be able to display the StreetNumber (INT) and the StreetName (CHAR) together in one field. This display would be read only. Is there a way to concatenate the two fields into one?

You can convert the integer to characters using either the CAST function or other data type conversion function supported by your database. Then use the concatenation operator as follows:

SELECT ConvertedStreetNumber||' '||StreetName from TABLE...
The double bars perform the actual concatenation.
