OpenEdge Data Management: DataServer for Microsoft SQL Server

Database design issues
For example, if you use the default code page 1252 and the default case insensitive sort ordering
with a MS SQL Server data source, collation of the tilde character (~), which is ASCII character
126, sorts before all the alphanumeric characters (0–9, a–z). If you were to select data from a
character column name with the following:
select * from table where name =CHR(126)
MS SQL Server returns records with columns that begin with a tilde character followed by all
that begin with alphanumeric characters. However, the default OpenEdge collation, which sorts
the tilde higher than all the alphanumeric characters, would omit records beginning with
alphanumeric characters and only return records beginning with the tilde character.
To get the full result set returned from MS SQL Server from the OpenEdge client would require
modifying the collation table associated with the OpenEdge code page and weighting it to match
the MS SQL Server sort order.
