ViewCriteria error with Timestamp

Question

I'm trying to use viewCriteria with a timestamp. But I'm getting some query errors.
I've done some tests.
1 - Entity attribute is oracle.jbo.domain.Date.
I create the date with the following code:
oracle.jbo.domain.Date d = new oracle.jbo.domain.Date(new java.sql.Timestamp(new java.util.Date().getTime()));
The code for the view criteria:
ViewCriteria vc = this.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
vcr.setAttribute("Hiredate", date created);
vc.addElement(vcr);
this.applyViewCriteria(vc);
this.executeQuery();
Here is the error:
oracle.jbo.SQLStmtException: JBO-27122: SELECT Emp.EMPNO,
Emp.ENAME,
Emp.JOB,
Emp.MGR,
Emp.HIREDATE,
Emp.SAL,
Emp.COMM,
Emp.DEPTNO
FROM EMP Emp
WHERE (((Emp.HIREDATE = TO_DATE('2006-11-28 13:09:54.0', 'yyyy-mm-dd'))))
The query is correct, using to_date function. But there is not a time mask.
2 - Entity Attribute is oracle.jbo.domain.Timestamp
I create the timestamp with the following code:
oracle.jbo.domain.Timestamp d = new oracle.jbo.domain.Timestamp(new java.sql.Timestamp(new java.util.Date().getTime()));
the code for the viewcriteria is the same as in test 1, except that I pass the timestamp object instead of the date to the setAttribute mehtod.
Here is the error:
oracle.jbo.SQLStmtException: JBO-27122: SELECT Emp.EMPNO,
Emp.ENAME,
Emp.JOB,
Emp.MGR,
Emp.HIREDATE,
Emp.SAL,
Emp.COMM,
Emp.DEPTNO
FROM EMP Emp
WHERE (((Emp.HIREDATE = '2006-11-28 13:13:25.019')))
Now the query was constructed with out the to_date function.
How can I use ViewCriteria with a Timestamp ?
Thanks a lot.

Answer 1

You should be able to workaround this issue using a customized OracleSQLBuilderImpl class patterned after the following:
package example;
import oracle.jbo.AttributeDef;
import oracle.jbo.ViewCriteria;
import oracle.jbo.ViewObject;
import oracle.jbo.common.Diagnostic;
import oracle.jbo.domain.Timestamp;
import oracle.jbo.server.OracleSQLBuilderImpl;
import oracle.jbo.server.SQLBuilder;
public class CustomOracleSQLBuilderImpl extends OracleSQLBuilderImpl {
    protected String getFormattedRHSCompareFragment(ViewObject vo,
                                                    ViewCriteria vc,
                                                    AttributeDef attrDef,
                                                    int sqlType, String rhs) {
        if (Timestamp.class.equals(attrDef.getJavaType())) {
            return new StringBuffer("TO_DATE('")
                        .append(rhs)
                        .append("', 'yyyy-mm-dd')")
                        .toString();
        else {
          return super.getFormattedRHSCompareFragment(vo, vc, attrDef, sqlType,
                                                    rhs);
    private static SQLBuilder mSQLBuilderInterface;
    synchronized public static SQLBuilder getInterface()
       if (mSQLBuilderInterface == null)
          if (Diagnostic.isOn())
             Diagnostic.println("CustomOracleSQLBuilder reached getInterface");
          mSQLBuilderInterface = (SQLBuilder)(new CustomOracleSQLBuilderImpl());
          if (Diagnostic.isOn())
             Diagnostic.println(mSQLBuilderInterface.getVersion());
       return mSQLBuilderInterface;
}To use a custom SQLBuilder class, you'll need to set the jbo.SQLBuilder property to the fully-qualified name of your custom SQLBuilder class. For example, to use the above class, the value would be example.CustomOracleSQLBuilderImpl
And, of course, the special-case code for the Timestamp attribute would need to be more sophisticated to handle possibly-different forms of querying for a timestamp with varying amounts of time information.
