Merging different values in a column using a separator

Question

0.00/5 (No votes)

See more:

I want to get Id and Text value from database in such a manner that both are returned as a single column with values separated by some separator. I'm thinking of using '$' sign as separator of values. eg: Suppose if Id is 10 and Text is 'abc', in my current way value will be returned as '10$abc'. I want to know is there any standard of using some specific operators to combine values or one can use any separator one desires?;

Solution 1

There is no standard way to do so, because in most of the cases it is a bad idea to do string manipulation in SQL...
However you can use CONCAT[^] to do so easily (for a fixed list of columns):

SQL

declare @sep as nchar(1) = '$'
select
  concat(col1, @sep, col2, @sep, col3, @sep, col4)
from
  table1

(you may need some casting, depending on the column data types)

So as you just said, there is no convention available to use specific operators only while appending values in a single column.
