Answer 1

I don't think your Oracle SQL statement (as defined in the prepared statement) is valid. When using the insert into [table] values(...) syntax, you don't use column=value expressions.

If you're specifying all of the column values in the correct order, then use this:

psmt=con.prepareStatement("Insert into TR_LogTime values((Select count(*) from Tr_LogTime) + 1 ,(select sysdate from dual), ?, ?, ?, ?,(select to_date(?,'dd/mm/yyyy')from dual) ,?,?,?,?,?)");

Otherwise, if you're only specifying a subset of the columns, use the syntax of

insert into TR_LogTime (col1, col2, col3, ...) values (?, ?, ?, ...)

(I didn't specify the exact column names in your example since I don't know all of them)

More on this syntax .

Answer 2

try this:

Insert into TR_LogTime (XXX, YYY, Prj_Id, Area_id, Activity_Id, ID_No, Work_Date, Work_Hours, Division, Description, Remarks, Work_Week) values (
(Select count(*) from Tr_LogTime) + 1 , (select sysdate from dual) , ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

You'll need to replace XXX and YYY with the appropriate column names
