Wm_Valid: Fail to convert to internal representation error while inserting

Question

Hi,
I'm trying to execute an insert via XmlCommand. The table is created with this statement:
create table testtable4 (testtable4_pk number, mydate date, myts timestamp with time zone, wm_valid wm_period);
I have a problem while inserting on a simple table with wm_period field. The c# code is the following:
OracleConnection oraConnection;
OracleCommand insertCommand;
string[] KeyColumnsList = null;
string[] UpdateColumnsList = null;
string xml1 = "<?xml version=\"1.0\"?>\n" +
"<ROWSET>\n" +
"<MYROW num = \"1\">\n" +
"<TESTTABLE4_PK>1</TESTTABLE4_PK><MYDATE>2012-01-20T00:00:00.00000</MYDATE><MYTS>01-01-11T00:00:00.000000000 +00:00</MYTS>" +
"</MYROW>\n" +
"</ROWSET>\n";
string xml2 = "<?xml version=\"1.0\"?>\n" +
"<ROWSET>\n" +
"<MYROW num = \"2\">\n" +
"<TESTTABLE4_PK>2</TESTTABLE4_PK><MYDATE>2012-01-20T00:00:00.00000</MYDATE><MYTS>01-01-11T00:00:00.000000000 +00:00</MYTS><WM_VALID><VALIDFROM>01-01-11T00:00:00.000000000 +00:00</VALIDFROM></WM_VALID>" +
"</MYROW>\n" +
"</ROWSET>\n";
KeyColumnsList = new string[1];
KeyColumnsList[0] = "TESTTABLE4_PK";
UpdateColumnsList = new string[4];
UpdateColumnsList[0] = "TESTTABLE4_PK";
UpdateColumnsList[1] = "MYDATE";
UpdateColumnsList[2] = "MYTS";
UpdateColumnsList[3] = "WM_VALID";
try
string ConnString = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=" + host + ")(PORT=" + port + ")))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=" + sid + ")));User Id=" + username + ";Password=" + password + ";";
oraConnection = new OracleConnection(ConnString);
oraConnection.Open();
using (OracleCommand cmd = new OracleCommand())
cmd.Connection = oraConnection;
cmd.CommandText = "alter session set NLS_DATE_FORMAT = 'YYYY-MM-DD\"T\"HH24:MI:SS.SSSSS'";
cmd.ExecuteNonQuery();
cmd.CommandText = "alter session set NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD\"T\"HH24:MI:SS.SSSSS'";
cmd.ExecuteNonQuery();
cmd.CommandText = "alter session set NLS_TIMESTAMP_TZ_FORMAT = 'YYYY-MM-DD\"T\"HH24:MI:SSXFF TZH:TZM'";
cmd.ExecuteNonQuery();
insertCommand = new OracleCommand();
insertCommand.Connection = oraConnection;
insertCommand.XmlCommandType = OracleXmlCommandType.Insert;
insertCommand.XmlSaveProperties.KeyColumnsList = KeyColumnsList;
insertCommand.XmlSaveProperties.RowTag = "MYROW";
insertCommand.XmlSaveProperties.Table = "TESTTABLE4";
insertCommand.XmlSaveProperties.UpdateColumnsList = UpdateColumnsList;
insertCommand.XmlSaveProperties.Xslt = null;
insertCommand.XmlSaveProperties.XsltParams = null;
//this works
insertCommand.CommandText = xml1;
insertCommand.ExecuteNonQuery();
//this fails
insertCommand.CommandText = xml2;
insertCommand.ExecuteNonQuery();
insertCommand.Dispose();
oraConnection.Close();
oraConnection.Dispose();
catch (Exception err)
this.WriteLogErr("ERROR: " + err.Message);
With the first ExecuteNonQuery I attempt an insert of a data value and a timestamp with timezone value. The execution is ok (xml1).
When the second ExecuteNonQuery is run (with the value of wm_valid), the execution fails with this error:
ERROR: ORA-29532: Java call terminated by uncaught Java exception: oracle.xml.sql.OracleXMLSQLException: 'java.sql.SQLException: Fail to convert to internal representation: 01-01-11T00:00:00.000000000 +00:00' encountered during processing ROW element 0. All prior XML row changes were rolled back. in the XML document.
ORA-06512: at "SYS.DBMS_XMLSAVE", line 111
ORA-06512: at line 1
The stored procedure at row 111 calls this Java method:
oracle.xml.sql.dml.OracleXMLStaticSave.insertXML(int, java.lang.String) return int
The structure of complex data type wm_period is:
CREATE OR REPLACE TYPE wm_period AS OBJECT (
validfrom TIMESTAMP WITH TIME ZONE,
validtill TIMESTAMP WITH TIME ZONE);
The problem is: I am able to insert a timestamp with timezone value (myts) but I'm not able to insert a wm_valid that contains two values of the same type...
This works: <MYTS>2011-01-01T00:00:00.00000</MYTS>
This fails: <WM_VALID><VALIDFROM>2011-01-01T00:00:00.00000</VALIDFROM></WM_VALID>
I also tried to change the format of NLS_TIMESTAMP_TZ_FORMAT with a lot of various setup, but nothing changed.
Thanks in advance for your precious help.
Best Regards,
Mario.

Hi jschell ...thnx for ur reply......
the getString(2) parameter is just avarchar which
return the error from the procedure, if its ok,then
the query is executed properly..its just a check I've
kept to jump into the next step.If the status is OK,
then I'm retrieving the values from the cursor. I'm
getting right value for this parameter.I wasn't questioning the logic. I understand what you are doing.
However JDBC drivers can have problems when items are retrieved out of order.
You might also try switching driver types. If the thin works and oci doesn't (or visa-versa) then you know it is a driver problem and you will just have to try a work around.
