Question

I’m using Advantage Database Server 9.10, and I want to append a text to Memo field.

I tried this way,

UPDATE 
  myTable 
SET 
  memo =   cast(memo as SQL_VARCHAR(max)) 
         + cast(' Appended string' as SQL_VARCHAR(max)) 
WHERE 
  pk = '80'

but it does not work,

anybody know how to do this?

Answer 1

There is no VARCHAR(MAX) data type in ADS, but you can cast to SQL_VARCHAR or SQL_CHAR instead.

Correct syntax:

UPDATE
  myTable 
SET 
   memo =   cast(memo as SQL_VARCHAR) 
          + cast(' Appended string' as SQL_VARCHAR) 
WHERE 
   pk = '80'

You can find the valid list of data types for CAST and CONVERT in the ads documentation:
