Bug reference: 6292
Logged by: David Pinheiro
Email address: davidsantospinhe...@gmail.com
PostgreSQL version: 8.4
Operating system: Linux
Description: java.sql.PreparedStatement.setNull() throws
PSQLException
Details:
I'm trying to make:
java.sql.PreparedStatement.setNull(1,java.sql.Types.NULL);
But i get:
org.postgresql.util.PSQLException: ERROR: column "number_column" is of type
integer but expression is of type character varying
Hint: You will need to rewrite or cast the expression.
My code is something like:
if (String.valueOf(input_field) == "null"){
statement.setNull(1, java.sql.Types.NULL);
} else {
statement.setObject(1, valor);
}
statement.executeUpdate();
Java says:
org.postgresql.util.PSQLException: ERROR: column "number_column" is of type
integer but expression is of type character varying
Hint: You will need to rewrite or cast the expression.
