I'm trying to insert a date into a TIMESTAMP field in an Oracle database from a servlet. but when I do the insert, I get an error: "ORA-01843: month not valid"
The type of date I see in the table where the date is is this: 05-FEB-19 09.36.10.000000000 AM and I declared it when the table was created as a TIMESTAMP type.
In JSP file i have this 2 input type:
<label>Data
<input type="date" name="date" value="13-AUG-2019" required>
</label>
<label>Time
<input type="time" name="time" value="11:00:00 AM" required>
</label>
In a Servlet Java i have this:
String data= request.getParameter("date");
String time= request.getParameter("time");
String paramData = data.replaceAll("\n", "");
String paramTime = time.replaceAll("\n", "");
String dataTime = paramData + " " + paramTime;
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection connCf = DriverManager.getConnection(url, user, pass);
PreparedStatement pstmtCf=connCf.prepareStatement("insert into screening_tab (film_oid, room_oid, data_hour) values((select ref(fi) from film_tab fi where fi.title=?), (select ref(ro) from room_tab ro where ro.code=?), ?)");
pstmtCf.setString(1, paramFilm);
pstmtCf.setString(2, paramRoom);
String paramDataTime= paramData + " " + paramTime;
pstmtCf.setString(3, paramDataTime);
Boolean result= pstmtCf.execute();
how can I solve this problem?
I Have tried this solution in Oracle 10 that given a string from servlet returns timestamp but the problem is the same:
create or replace procedure Sdata (datatime VarCHAR2) is
date_ho TIMESTAMP;
begin
SELECT TO_TIMESTAMP (datatime, 'DD-MON-RR HH.MI.SSXFF AM') into date_ho FROM DUAL;
dbms_output.enable;
dbms_output.put_line(date_ho);
end sdata;
Between the various attempts and trials, i can not explain how, if I do something like this in Oracle SQL Developer everything works correctly!:
insert into screening_tab (film_oid, room_oid, data_hour) values((select ref(fi) from film_tab fi where fi.title='FilmNumero601'), (select ref(ro) from room_tab ro where ro.code=301), '14-DEC-19 07.00.00.00 PM' );
when I run the exact same query from the servlet I always get the error on the invalid month date
I have tried also this solution: I have created a new Servlet and JSP file where this input for data is:
<h4>Select Data: </h4><br></br>
<input type="datetime-local" name="date" arequired placeholder="Date">
<br></br>
<input type="reset" value="Resetta la form"></input>
<input type="submit" value="Invia"></input>
In the corresponding servlet i have this:
PreparedStatement pstmtCf=connCf.prepareStatement("insert into screening_tab (film_oid, room_oid, data_hour) values((select ref(fi) from film_tab fi where fi.title=?), (select ref(ro) from room_tab ro where ro.code=?), ?)");
pstmtCf.setString(1, film);
pstmtCf.setString(2, room);
String date= getCorrectFormat(request.getParameter("date")+":00");
pstmtCf.setString(3, date );
pstmtCf.execute();
pstmtCf.close();
connCf.close();
Where getCorrectFormat() is:
public static String getCorrectFormat(String date){
String out="";
out += (date.substring(8,10))+ "-";
switch(date.substring(5,7)){
case "01":
out += "JAN-";
break;
case "02":
out += "FEB-";
break;
case "03":
out += "MAR-";
break;
case "04":
out += "APR-";
break;
case "05":
out += "MAY-";
break;
case "06":
out += "JUN-";
break;
case "07":
out += "JUL-";
break;
case "08":
out += "AUG-";
break;
case "09":
out += "SEP-";
break;
case "10":
out += "OCT-";
break;
case "11":
out += "NOV-";
break;
case "12":
out += "DEC-";
break;
}
out += (date.substring(0,4))+ " ";
int hour =Integer.parseInt(date.substring(11,13))%12;
if(hour == 0)
out += String.valueOf(12);
else
out += String.valueOf(hour);
out += (date.substring(13));
if(Integer.parseInt(date.substring(11,13))<12)
out += " AM";
else
out += " PM";
return out;
}
The error is always the same: "ORA-01843:not a valid month"
