The following bug has been logged online: Bug reference: 1628 Logged by: Nathan Neuenschwander Email address: nathan_neuenschwander@comcast.net PostgreSQL version: 8.0 Operating system: Win XP Description: JDBC bug with regard to text column data type Details: I am using a CachedRowSet, the JDBC driver for PG 8.0, and j2ee. If the target table contains a column of data type text, the following causes an SQLException with a message stating that a negative value was returned for the column display size. If the text column is changed to a varchar, the exception is not triggered. The exception is not dependent upon the particular column being queried, just the enclosing table. (The proper variable init is implied.) SQL # Create column with text data type. Create Table table_a(field1 Integer, field2 text); // Java cachedrowset.setCommand("Select field2 from table_a"); cachedrowset.execute(connection); // Results in Exception. SQL # Create column with varchar data type. Create Table table_b(field1 Integer, field2 varchar(100)); // Java cachedrowset.setCommand("Select field2 from table_b"); cachedrowset.execute(connection); // No Exception.
