Concatenation of strings and numerical-values in SQL:

I have a table  e.g. (a Paradox-Table named "Table.db") with the columns:
  TabID    (Integer - long)
  TabName  (alphanumeric)

I want to generate a Query which concatenates 'TabID' and 'TabName'.
(  SELECT TabID, (TabID || TabName) As TabIDName FROM "Table.db"
   <- but this works only when TabID is already a String-value;
      Auto-Conversion of numerical values to strings does not work. )

My Problem:
 How can I cast the numerical value 'TabID' to a String-value?
 I've found no function (e.g. Str(<Number>))
 I've found no operator (e.g. &  (Ampersand) in ACCESS which implicit
                         casts numerical values to Strings)
 There is no hint in the 'Localsql.hlp' of BDE
