Обсуждение: Throwing NumberFormat exception for preparedStatement.setObjcet()
Hi,
In our application we are using the Postgres Sql 8.3.3 and jdbc driver is postgresql-8.0-310.jdbc3.
When I am trying to set the value for id(int) like as follows throwing exception.
ps.setObject(1, inputData,columntype);
where inputdate value is 2
if I modified the above statement like as follows then it works fine.
ps.setObject(1, inputData);
I want to know what could be the proble.
Thanks,
Srinvias

It looks like you to me off hand that the targetSqlType may possibly not
be a ROWID
per the documentation. Also maybe check that value, columntype, to
insure matches.
===================================================================
setObject
void setObject(int parameterIndex,
Object x,
int targetSqlType)
throws SQLException
Sets the value of the designated parameter with the given object. This
method is like
the method setObject above, except that it assumes a scale of zero.
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
x - the object containing the input parameter value
targetSqlType - the SQL type (as defined in java.sql.Types) to be sent
to the database
Throws:
SQLException - if parameterIndex does not correspond to a parameter
marker in the SQL
statement; if a database access error occurs or this method is called on
a closed PreparedStatement
SQLFeatureNotSupportedException - if targetSqlType is a ARRAY, BLOB,
CLOB, DATALINK,
JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or
STRUCT data type and the JDBC driver does not support this data type

Thanks for your reply. Here columnType value is 3 and inputdata value is always string type. -----Original Message----- From: davecramer@gmail.com [mailto:davecramer@gmail.com] On Behalf Of Dave Cramer Sent: Tuesday, January 12, 2010 1:45 AM To: Srinivas Gunnam Cc: pgsql-jdbc@postgresql.org Subject: Re: [JDBC] Throwing NumberFormat exception for preparedStatement.setObjcet() On Mon, Jan 11, 2010 at 7:58 AM, Srinivas Gunnam <srinivas_gunnam@persistent.co.in> wrote: > Hi, > > In our application we are using the Postgres Sql 8.3.3 and jdbc driver is > postgresql-8.0-310.jdbc3.

If I were writing it I would use java.sql.Types.Integer as the columnType, not the numeric value. And inputData should be an Integer.

The reason it's throwing a NumberFormatException is that you're passing something which isn't a number. With a later driver version you wouldn't get this exception, but instead the server would complain that it wasn't a valid number. The attached test case shows this working just fine from my perspective. Kris Jurka
