Обсуждение: Inserting Information in PostgreSQL interval

Hey,

I am having trouble entering intervals into a PostgreSQL inverval field.
Currently I using prepared statements that look like this:

{code}

PreparedStatement query = conn.prepareStatement("INSERT............");
query.setObject(1, "{28.1, 29.2}");
query.setObject(2, "{1:23, 1:24}");
query.execute();
{code}

And when I execute the code I get this error:

org.postgresql.util.PSQLException: ERROR: column "field_1" is of type
interval[] but expression is of type character varying


So is there another way of entering an array of intervals into a postgresql
database using prepared statement? What am I doing wrong?

The two-argument form of setObject() infers a type of Types.VARCHAR for
a java.lang.String (see the JDBC spec)

Try:

  query.setObject(1, "{28.1, 29.2}", Types.OTHER);

-O

Hey, that worked!

Thanks a lot.
