My "for loop" on java only return the result on the first row of jtable and repeat it for the rest number of row

So I have some issue on my for loop. It only work on the first row of jtable and printed the same result to the whole rows. here's my code:
try {
int row = tblHasil.getRowCount();
for (int i = 0; i < row; i++) {
String tempA = (String) tblHasil.getModel().getValueAt(i, 3);
String tempB = (String) tblHasil.getModel().getValueAt(i, 4);
String tempC = (String) tblHasil.getModel().getValueAt(i, 5);
double a = Double.parseDouble(tempA);
double b = Double.parseDouble(tempB);
double c = Double.parseDouble(tempC);
VNilaiRataRata.setNilaiRataRata(a);
VTanggungan.setTanggungan(b);
VPenghasilan.setPenghasilan(c);
Rules.hitung_u();
Rules.hitung_z();
DecimalFormat df = new DecimalFormat("#########.###");
double hasildef = Double.parseDouble(df.format(Rules.defuzzifikasi()));
VKeterangan.setKeterangan(hasildef);
double keterangan = VKeterangan.getKeterangan();
double tidakLolos = VKeterangan.tidaklolos();
double cadangan = VKeterangan.cadangan();
double lolos = VKeterangan.lolos();
String desc;
if (lolos > cadangan && lolos > tidakLolos) {
desc = "Lolos";
tblHasil.setValueAt(desc, i, 6);
} else if (cadangan > tidakLolos && cadangan > lolos) {
desc = "Cadangan";
tblHasil.setValueAt(desc, i, 6);
} else {
desc = "Tidak Lolos";
tblHasil.setValueAt(desc, i, 6);
}
System.out.println("Nama : " + tblHasil.getModel().getValueAt(i, 1));
System.out.println("Hasil Fuzzi : " + hasildef);
System.out.println("Keterangan Value : " + keterangan);
System.out.println("Keterangan Tidak Lolos : " + tidakLolos);
System.out.println("Keterangan Cadangan : " + cadangan);
System.out.println("Keterangan Lolos : " + lolos);
System.out.println("Nilai Rata2 : " + VNilaiRataRata.getNilaiRataRata());
System.out.println("Tangungan : " + VTanggungan.getTanggungan());
System.out.println("Penghasilan : " + VPenghasilan.getPenghasilan());
System.out.println("Keterangan : " + desc);
System.out.println("================================");
System.out.println();
Connection cn = DriverManager.getConnection("jdbc:mysql://localhost/db_siswa", "root", "");
int nis = Integer.parseInt(tblHasil.getModel().getValueAt(i, 0).toString());
String sql = "UPDATE nilaisiswa SET hasil='" + desc + "' WHERE nis = '" + nis + "'";
cn.createStatement().executeUpdate(sql);
}
} catch (Exception e) {
e.printStackTrace();

How to add double quotes to the output values in a Resultset when the column datatype is String?

I am trying to run the below query and insert the output of it into another table (postgres db):
String ssnQuery = "SELECT period_year, period_name, period_num, NULL as count_of_issues,
ledger_id,
balancing_segment,
Count(*) AS count_of_account_segments,
Sum(accounted_period_net_dr) AS balance_accounted_period_net_dr,
Sum(accounted_period_net_cr) AS balance_accounted_period_net_cr,
Round(Sum(accounted_period_net_dr_cr)) AS balance_accounted_period_net_dr_cr_diff,
Sum(entered_period_net_dr) AS balance_entered_period_net_dr,
Sum(entered_period_net_cr) AS balance_entered_period_net_cr,
Round(Sum(entered_period_net_dr_cr)) AS balance_entered_period_net_dr_cr_diff,
Sum(begin_balance_dr) AS begin_balance_dr,
Sum(begin_balance_cr) AS begin_balance_cr,
Round(Sum(net_beginning_balance)) AS net_beginning_balance,
Round(Sum(net_closing_balance)) AS net_closing_balance
FROM schema.tablename";
try {
pstmnt = financeConnection.prepareStatement(ssnQuery);
rs = pstmnt.executeQuery();
rsmd = rs.getMetaData();
for(int i=1; i<=rsmd.getColumnCount(); i++) {
columnNames.add(rsmd.getColumnName(i));
if(i == 1) {
queryColumns = rsmd.getColumnName(i);
} else if(i<7) {
queryColumns += ", " + rsmd.getColumnName(i);
} else {
queryColumns += ", value_" + (i-7);
}
}
while (rs.next()) {
queryValues = " ";
for(String colname: columnNames) {
if(queryValues.isEmpty()) {
queryValues = rs.getString(colname);
} else {
queryValues += rs.getString(colname) + ", ";
}
}
remCommas = queryValues.replaceAll(", $", "");
insertQuery = "INSERT INTO bdmerge.gen_audit_func_hive_results (run_id, run_date, run_date_ist" + queryColumns + ") VALUES (" + runid +"," + utcTimeStamp + "," + istTimeStamp + "," + remCommas + ")";
System.out.println("Final Insert query: " + insertQuery);
}
} catch (SQLException e) {
e.printStackTrace();
} catch(Exception e) {
e.printStackTrace();
}
To insert the output of above query, I formed the insert query according the column names in the destination table as below:
INSERT INTO schema.destinationTable (run_id, run_date, run_date_ist, source_system_type, source_system, module, source_table_name, period_year, period_name, period_num, count_of_issues, count_of_accounted_issues, count_of_entered_issues, value_0, value_1, value_2, value_3, value_4, value_5, value_6, value_7, value_8, value_9, value_10, value_11, value_12) VALUES (781,2018-11-12 08:15:32.0,2018-11-12 13:45:32.0, 2018, OCT-18, 10, null, 1, 1, 2073, ATRS, 6135, 6.2778220466107E11, 6.277946274560101E11, -1.2422795E7, 5.929031383587201E11, 5.9291556115366E11, -1.2422795E7, 3.931397937759116E13, 3.9313979377591164E13, 0.0)
But the destination table's columns:
run_id, count_of_issues, count_of_accounted_issues, count_of_entered_issues
are in numeric format (working on postgres db) and all others are varchar(1000).
In order to insert the varchar data, I need to enclose the column values from value_0 till value_12 in double quotes.
Without properly modifying the data, I am getting SQLException while inserting which is expected.
Is there any way I can just enclose those varchar column values from the resultSet in double quotes and insert them into destination table?

You need to add double quotes to the string values; Use Escape characters, like this:
String quotedStr = "Non Quoted," + " \"Quoted\".";
Modifying your code to address the problem:
while (rs.next()) {
queryValues = " ";
int i = 0;
for(String colname: columnNames) {
if(queryValues.isEmpty()) {
queryValues = rs.getString(colname);
} else {
if (i >= 7)
queryValues += "\"" + rs.getString(colname) +"\"" + ", ";
}
else
queryValues += rs.getString(colname) + ", ";
i++;
}

Your rsParameters parameter is of Type Resultset.
In first iteration, after try{} block is complete close() method of rsParameters:ResultSet is called.
This internally makes all the properties of resultSet NUll.
That is the reason for getting Null properties during second iteration.

Trouble Updating a Table Row in Java

Connection conn = SqlConnection.getConnection("jdbc:mysql://localhost:3306/stocks");
Statement statement = conn.createStatement();
File path = new File("/Users/Zack/Desktop/JavaDB/BALANCESHEETS");
for(File file: path.listFiles()) {
if (file.isFile()) {
String fileName = file.getName();
String ticker = fileName.split("\\_")[0];
if (ticker.equals("ASB") || ticker.equals("FRC")) {
if (ticker.equals("ASB")) {
ticker = ticker + "PRD";
}
if (ticker.equals("FRC")) {
ticker = ticker + "PRD";
}
}
//CSVReader reader = new CSVReader(new FileReader(file));
//List entries = reader.readAll();
//ArrayList<String> entry = new ArrayList<String>();
Reader reader = new BufferedReader(new FileReader(file));
StringBuilder builder = new StringBuilder();
int c;
while ((c = reader.read()) != -1) {
builder.append((char) c);
}
String string = builder.toString();
ArrayList<String> stringResult = new ArrayList<String>();
if (string != null) {
String[] splitData = string.split("\\s*,\\s*|\\n");
for (int i = 0; i <splitData.length; i++) {
if (!(splitData[i] == null) || !(splitData[i].length() ==0)) {
stringResult.add(splitData[i].trim());
}
}
}
String columnName = null;
int yearCount = 0;
for (int i = 0; i < stringResult.size(); i++) {
int sL = stringResult.get(i).length();
for (int x = 0; x < sL; x++) {
if (Character.isLetter(stringResult.get(i).charAt(x))) {
yearCount = 0;
System.out.println("index: " + i);
columnName = stringResult.get(i);
columnName = columnName.replace(" ", "_");
System.out.println(columnName);
i++;
break;
}
}
yearCount++;
String value = stringResult.get(i);
System.out.println("Year: " + stringResult.get(yearCount) + " Value: " + value + " Stock: " + ticker + " Column: " + columnName );
if (!(columnName == null)) {
String writeValues = "INSERT INTO BalanceSheet (ticker, Year, " + columnName + ") "
+ "VALUE ('" + ticker + "','" + stringResult.get(yearCount) + "','" + value + "')";
String writeValues2 = "UPDATE BalanceSheet "
+ "SET ticker = '" + ticker + "', "
+ "Year = '" + stringResult.get(yearCount) + "', "
+ columnName + " = '" + value + "' "
+ "WHERE ticker = '" + ticker + "'";
statement.executeUpdate(writeValues2);
}
}
Towards the bottom of the code are two queries I tried, I'm trying to get all data organized by ticker and year into a table, "writeColumns" works but it's making a new row for every new "value" put into "columnName". My second attempt "writeColumns2" doesn't do anything.
I want to update the same row with a certain year for all values and then move onto the next year, then next ticker.

If I have understood your question correctly, you want to insert a row if it doesn't exists but update the values if it already does. You need to use ON DUPLICATE KEY UPDATE
String writeValues = "INSERT INTO BalanceSheet (ticker, Year, " + columnName + ") "
+ "VALUES (?,?,?) "
+"ON DUPLICATE KEY UPDATE " + columnName +"=?";
Statement statement = conn.prepareStatement(writeValues);
statement.setString(1,ticker);
statement.setString(2,stringResult.get(yearCount));
statement.setString(3, value);
This will solve your immidiate problem provided you create a UNIQUE index on ticker,year
However there are lot's of other issues here.
An update for each column - Currently you are doing an insert/update for each column on the table. What you are supposed to do is to insert update all the columns at one.
You are not using prepared statements addressed in my code sample
You shouldn't be doing this at all the best way to batch process data is to use MYSQL's built in LOAD DATA INFILE command. If your data is not in a format that can be easily imported into mysql, what your Java code can do is to transform it into a format that can be. Such a code will be a lot simpler and neater than what you have now

Optimizing code for speed
