select on bytea column returns hex encoded data instead of binary data

Hi,

I am new to postgresql.

I've an application which displays the various binary files (like jpgs, xls, zips) stored in PostgrelSQL DB in bytea column.

I inserted these files in bytea column in a table using hex encoding.

But, when I try to access this column by executing (SQLExec) the query "select * from tablename;" from ODBC on Windows, the buffer contains the same hex encoded data.

I am using SQL_C_BINARY data type for SQLBindCol() function.

Can you please help me know, how can I retrieve the data stored in bytea columns in binary format?

Thanks in advance for help and guidance.

Best Regards,

Ganesh
