Bug with binding query parameters hangs entire connection instance. (Possib: msg#00187db.postgresql.jdbc
Hello. This may be an issue that you are all aware of, sorry for not digging through archives and such, but I simply don't have the time. Noting that support for CallableStatement is not yet implemented I elected to use the following format for calling user defined SQL Functions and dynamically bind parameters to them. PreparedStatement procedure = conn.prepareStatement("select someFunction(?,?,?)"); and then binding params with procedure.setObject(index, aStringOrIntegerOrSomeSuch); which mostly works fine. However, I discovered that in some cases, when the bound parameter is totatlly screwed, ie. Float when the function expects Integer, the PostgreSQL jdbc driver will throw an exception: java.sql.SQLException: ERROR: pg_atoi: error in "140.0": can't parse ".0" which is fine and all, except that any subsequent statements made to the connection instance in question will fail with: java.sql.SQLException: The query returned no rows which is not too great. For my application I made a workaround that runs a query I know should work before every query to determine if the connection instance is jammed and has to be re-instantiated... This introduced surprisingly little overhead with a pre prepared statement, but it is a kludgy annoyance nonetheless. Any ideas or comments? Summery greetings from Finland!
