Connection con = ConnectionHelper.getConnection(); Array tArray = con.createArrayOf("text", tuplas); PreparedStatement pstm = con.prepareStatement("select salvarArquivoGeometricoCasoZeroPOINT(?,?,?,?)"); pstm.setString(1,arquivo.getGeoType()); pstm.setString(2,arquivo.getTable()); pstm.setArray(3,tArray); pstm.setString(4,arquivo.getSrid()); rs = pstm.executeQuery(); ConnectionHelper it's my java.sql.Connection class.

This of course precludes recursive use then of the statement. To correctly set an array parameter via PgJDBC you must use: Array sqlArray = conn.createArrayOf("text", strArray); pstmt.setArray(1, sqlArray); pstmt.executeUpdate(); ...

This means that, unfortunately, you can not have an ArrayList of int or an ArrayList of char. this content Use setObject() with an explicit Types value to specify the type to use.I tried to convert it to string and insert like string with same syntax ('{1,2,3}')', but there was error Here is the code from the mousePressed() routine that does this: currentCurve = new CurveData(); // Create a new CurveData object.

As was I, I posted a patch a couple of months ago that did the same thing but also accepted java List types as well (I'm often using these especially with Using the FORALL and SAVE EXCEPTIONS keywords, the error handling becomes much better than can be achieved with JDBC batching. This is true in particular for parameterized types. weblink list.remove(obj) -- If the specified object occurs somewhere in the list, it is removed from the list.

For example: PreparedStatement.setObject(1, new String[]{"a"}). stmt.setObject(1, ora_payment_amount); stmt.setObject(2, ora_card_number); stmt.setObject(3, ora_expire_month); stmt.setObject(4, ora_expire_year); stmt.setObject(5, ora_name_on_card); // Bind the output array, this will contain any exception indexes. Notionally someone other than the submitter would review the patch.

You can also prevent ClassCastException in Java by using Generics. Is there a set of guidelines that need to be followed in determining if a patch should be accepted? maybe something like this. Kinda defeats the purpose, but for singluar inserts/update works fine.
