> Key: DERBY-4644
> URL: https://issues.apache.org/jira/browse/DERBY-4644
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.5.3.0
> Environment: window xp; jdk1.5
> Reporter: xiaofeng.zhang
>
> Reproduce steps:
> 1. Create a PreparedStatement with sql text "select * from tablename where
> column1 in (?,?)".
> 2. Call JDBC PreparedStatement .executeQuery( ) to execute this statement and
> it never stop. I found my CPU Usage is 100% after this happened.
> More info:
> 1. The SQL like "select * from tablename where column1 in (?)" can return an
> empty result set
> 2. If call PreparedStatement .setInt( 1,1 ) to set a parameter value the
> query can work
