SELECT on TIMESTAMP field from ABAP with EXEC SQL

Question

Hello,
I'm trying to get a field of one table which is defined as TIMESTAMP. MaxDB parameter DATE_TIME_FORMAT is set to INTERNAL. When I do the SELECT in SQL Studio I get ISO format 'YYYY-MM-DD HH:MM:SS.MMMMMM' back. So I tried a SELECT with ISO in WHERE clause, but I'm always getting a shortdump with this error:
Database error text........: "POS(82) Invalid date input value"
Database error code........: "-3065"
Then I did a SELECT without a WHERE clause in ABAP and got value '06-FEB-09' back from this field. So I tried with this ABAP statement and got no shortdump, but I also need to add time and not only the date.
  EXEC SQL.
    SELECT recv_time INTO :l_time FROM ztest WHERE sent_recv_time = '06-FEB-09'
  ENDEXEC.
I'm using Native SQL because the SELECT is on a table which is not located in SAP Schema User. "SELECT recv_time FROM ztest WHERE recv_time = '2009-02-24 10:02:55.888000'" works in SQL studio, but not from ABAP.
Does anyone know which format I need to specify in the WHERE clause?
Regards

Hi Thomas,
Thanks for your help. Unfortunately doesn't seem to work, I get following shortdumps (tried with 3 different notations):
Database error text........: " "
Database error code........: "-4005"
Triggering SQL statement...: "SELECT xxxxxx, status, sent_xxxx_time FROM
xxx_xxxxxxxxx WHERE sent_recv_time = "{ts'2009-02-06 04:05:06'}""
Database error text........: "POS(87) Invalid keyword or missing delimiter"
Database error code........: "-3008"
Triggering SQL statement...: "SELECT xxxxxx, status, sent_xxxx_time FROM
xxx_xxxxxxxxx WHERE sent_recv_time = '{ts' 2009-02-06 04:05:06 '}'"
Database error text........: "POS(81) Missing value specification"
Database error code........: "-5010"
Triggering SQL statement...: "SELECT xxxxxx, status, sent_xxxx_time FROM
xxx_xxxxxxxxx WHERE sent_recv_time = { ts '2009-02-06 04:05:06.000' }"
