PostgreSQL version: 7.4
Operating system: Linux (Insignificant)
Description: JDBC driver doesn't handle all dates correctly
Details:
In AbstractJdbc1Statement.setDate(int parameterIndex, java.sql.Date x), the
date 'x' is converted to a string by using x.toString() before being sent as
a parameter to a SQL-query, i.e. an INSERT-statement. The JavaDocs specify
that the result of this this toString method is the same as
new java.text.SimpleDateFormat("yyyy-MM-dd").format(x)
which, according to the documentation for SimpleDateFormat, will zero-pad
the year if it is less than four digits. This can happen if a very strange
date is chosen, which this case shows:
java.sql.Date x = new java.sql.Date(Long.MAX_VALUE);
System.out.println((int) x.toString().charAt(0));
This code will print '0'. Since x.toString() contains a null character, the
JDBC driver fails to send it as part of a query to the database by throwing:
java.sql.SQLException: ERROR: Unterminated quoted string

org.postgresql.core.QueryExecutor.executeV2(QueryExecutor.java:287)

at java:50)
org.postgresql.jdbc1.AbstractJdbc1Statement.executeUpdate(AbstractJdbc1Stat
at ement.java:273)
if I e.g. try to perform an INSERT-statement.
The problem may also be present with other types than java.sql.Date, I
haven't checked the details.
The error is present in all versions 7.2-7.4 of the JDBC driver as far as I
can see.
