@VISHNU DIVAKARAN PILLAI - you could try something like
where we use strcmp to return a logical array of zeros and ones where a one will indicate a match (i.e. identical to 'D"). This logical array will then be used to determine the value of the second column whose first column value matches to 'D'.

If you are always using the values of d as a 'key' to look up other table variables, I would use straightly use d as the table's RowNames:
d_address = pad(d_address,3,"left",'0')
d_address = 8×1 string array
"000" "001" "010" "011" "100" "101" "110" "111"
% note I replace ':' with '::' as ':' is a reserved subscripting character
dcode=table(d_address,'RowNames', d');
ans = table
d_address _________ D "010"
