PSQLException: Too many update results were returned.

hi

i have a big problem.

task: i need to execute multiple queries form some files. each file contains at about 50-100 query. the queries are from create table to create function ... almost everything. this batches should run on more than 600 databases.

my problem is:

i used the Statement.addBatch() to add the batch to the statement, and i execute batch with the Statement.executeBatch() method. the execution failes with the following error:

org.postgresql.util.PSQLException: Too many update results were returned.

i goggled all over the web to find out what is the source of this exception, but i don't find anything.

can someone explain to me what should i do. or at least what is the problem with this.

platform: linux with 2.6.20-16-generic kernel
db: PostgreSQL 8.1.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.3.5 (Debian 1:3.3.5-13)
jdbc: 8.1 jdbc3 (i don't know what build number is)

regards
