Symptoms



A select of data from MySQL using DG4ODBC 11.1 returns character data with spaces between the characters.
For example -

select "id", "username" from user_table@mysql where "id"=2;

id username
-- ------------
2  s m i t h


A dump of the data from Oracle shows the following -

select dump("username") from user_table@mysql where "id"=2;
 DUMP("USERNAME")
--------------------------------------------------------------------------------
Typ=1 Len=20: 0,0,0,115,0,0,0,109,0,0,0,105,0,0,0,1160,0,0,0,104



The same select run against MySQL using ISQL returns the correct data -

select id, username from user_table where id=2 ;

| id | username |
| 2 | smith |


The character set used by MySQL is UTF8 and by Oracle is AL32UTF8.
