How to convert a variable to string format? KSH shell scripting

I am trying to convert a variable to a string format so I can use java runsql utility to insert its value into a database later. The database needs the value to be in a char format, hence string.

This is a dumbed down version of my code so I can get to the heart of what I'm asking - 

#!/bin/ksh -x
value1=2018-01-01
value2=2018-02-01

mystring=$value1,$value2
echo $mystring

stringify=${'value1'},${'value2'})
echo $stringify

What happens is I get no output for stringify or depending on how I switch up the arrangement of the symbols I get the literal string 'value1' or 'value2'.

What am I doing wrong? I feel like this is very simple, maybe I've just been staring at it too long, I dunno.

You can just do like this, more simpler:

#!/bin/ksh -x
value1=2018-01-01
value2=2018-02-01

mystring=$value1,$value2
echo $mystring

stringify="'$value1','$value2'" #use double-quotes around the variables
echo $stringify

Output:

2018-01-01,2018-02-01
'2018-01-01','2018-02-01'

You can just escape quote like this:

mystring=\'$value1\',\'$value2\'

Output:

$ echo $mystring

'2018-01-01','2018-02-01'

A simpler option to get the same output (as suggested by @CharlesDuffy) is:

mystring="'$value1','$value2'"
