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.
