can't insert dt_str to char type

Hi,

Having problem with OLE-DB connection to informix.

Created a flat file has two columns and 2 row:
1|a
2|b

tried to load it to a informix table:
create table t
( c1  int,
  c2 char
);

2 rows inserted, but only column c1 got data.

Changed c2 from char to varchar then ok.

thanks for any help.
