I'm running Postgresql 7.1.2 on a RedHat 7.1 machine. I have the jdbc
drivers jdbc7.1-1.2.jar.
I have been trying to figure out how the blob support works. I made a
table of this format:
djweis=# \d blobtest
id | integer |
theblob | bytea |
This is the code that I'm using to grab the value of 'theblob':
conn.setAutoCommit(false);
PreparedStatement stmt = conn.prepareStatement("SELECT theblob
FROM blobtest WHERE id = ?");
stmt.setInt(1, 1);
ResultSet rset = stmt.executeQuery();
while (rset.next()) {
Blob foo = rset.getBlob("theblob");
System.out.println("length is " + foo.length());
}
But instead of getting just the length, I get this:
[djweis@djweis pgblob]$ java -cp jdbc7.1-1.2.jar:. test
hello, world
Bad Integer I wish this would work
at org.postgresql.jdbc2.ResultSet.getInt(ResultSet.java:269)
at org.postgresql.jdbc2.ResultSet.getBlob(ResultSet.java:964)
at org.postgresql.jdbc2.ResultSet.getBlob(ResultSet.java:959)
at test.main(test.java:30)
Bad Integer I wish this would work
[djweis@djweis pgblob]$
I never printed the contents of the blob, but there they are... I inserted
the data by hand, but once I figure out how to do this, I'll need to
insert the data from InputStreams and get it back using OutputStreams.
Any ideas?
Thanks
dave
