Corrupted PreparedStatement

Question

The following code give me this error after approx. 90 update:
java.sql.SQLException: Syntax error or access violation, message from server: "You have an error in your SQL syntax near 'U31/pE t_cotation SET rsi = 59.465478841870826 WHERE no_cotation = 756' at line 1"
public void majDB() throws SQLException {
        String strRequete;
        PreparedStatement psRequete;
        strRequete = "UPDATE t_cotation SET rsi = ? WHERE no_cotation = ?";
        for (int i = 0; i < this.lCotation.size(); i++) {
            psRequete = this.DH.preparedStatement(strRequete);
            Cotation cTemp = (Cotation)this.lCotation.get(i);
            if (cTemp.dValeurRSI == 0) {
                psRequete.setNull(1, Types.DOUBLE);
            } else {
                psRequete.setDouble(1, cTemp.dValeurRSI);
            psRequete.setInt(2, cTemp.iCotation);
            psRequete.executeUpdate();
}Windows XP

Did you copy and paste the code?Yeah the is the one I paste in my first post
public void majDB() throws SQLException {
        String strRequete;
        PreparedStatement psRequete;
        strRequete = "UPDATE t_cotation SET rsi = ? WHERE no_cotation = ?";
        psRequete = this.DH.preparedStatement(strRequete);
        for (int i = 0; i < this.lCotation.size(); i++) {
            Cotation cTemp = (Cotation)this.lCotation.get(i);
            if (cTemp.dValeurRSI == 0) {
                psRequete.setNull(1, Types.DOUBLE);
            } else {
                psRequete.setDouble(1, cTemp.dValeurRSI);
            psRequete.setInt(2, cTemp.iCotation);
            psRequete.executeUpdate();
        psRequete.close();
