How to update timestamp column in PostgreSQL database?

How to update timestamp column in PostgreSQL database? - java

I am trying to update PostgreSQL database column. I do not know how to parse and send it to the database which matches the data type? How do I do this?
Here is my Code:
#Override
public void updateTaskStatus(String applicationNo, String prevTask, String currTask, String taskStatus,
String user) {
Connection conn = null;
PreparedStatement ps = null;
PreparedStatement ps2 = null;
PreparedStatement ps3 = null;
ResultSet rs = null;
java.util.Date date = new java.util.Date();
Timestamp timestamp = new Timestamp(date.getTime());
try {
conn = ConnectionManager.getConnection();
String query = "SELECT * " + "FROM public.nt_t_task_det " + "where tsd_app_no=? ;";
ps = conn.prepareStatement(query);
ps.setString(1, applicationNo);
rs = ps.executeQuery();
if (rs.next() == true) {
if (!(rs.getString("tsd_task_code").equals(currTask))) {
// insert to history table
String q = "INSERT INTO public.nt_h_task_his "
+ "(tsd_seq, tsd_vehicle_no, tsd_app_no, tsd_task_code, tsd_status, created_by, created_date) "
+ "VALUES(?, ?, ?, ?, ?, ?, ?); ";
ps2 = conn.prepareStatement(q);
ps2.setInt(1, rs.getInt("tsd_seq"));
ps2.setString(2, rs.getString("tsd_vehicle_no"));
ps2.setString(3, applicationNo);
ps2.setString(4, prevTask);
ps2.setString(5, taskStatus);
ps2.setString(6, rs.getString("created_by"));
ps2.setTimestamp(7, rs.getTimestamp("created_date"));
int i = ps2.executeUpdate();
conn.commit();
try {
if (ps2 != null)
ps2.close();
} catch (Exception e) {
e.printStackTrace();
}
conn.commit();
if (i > 0) {
// update task details table
String q2 = "UPDATE public.nt_t_task_det "
+ "SET tsd_task_code=?, tsd_status='O', created_by=?, created_date=? "
+ "WHERE tsd_app_no=?";
ps3 = conn.prepareStatement(q2);
ps3.setString(1, currTask);
ps3.setString(2, applicationNo);
ps3.setString(3, user);
ps3.setTimestamp(4, timestamp);
ps3.executeUpdate();
conn.commit();
try {
if (ps3 != null)
ps3.close();
} catch (Exception e) {
e.printStackTrace();
}
String queueNumber = findQueueNumberFromApplicationNo(conn, applicationNo);
if (queueNumber != null && !queueNumber.isEmpty() && !queueNumber.trim().equalsIgnoreCase("")) {
updateQueueNumberTaskInQueueMaster(conn, queueNumber, currTask, "O");
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (rs != null)
rs.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
if (ps != null)
ps.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
if (ps2 != null)
ps2.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
if (conn != null)
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Here is the exception in my console:
org.postgresql.util.PSQLException: ERROR: column "created_date" is of
type timestamp without time zone but expression is of type character
varying
Hint: You will need to rewrite or cast the expression.

The parameters of the UPDATE statement don't match the arguments you are supplying.
The first argument is for the first ?, the second one for the second and so on. You got the order mixed up.

Insert to database using web service in java

when i wrote function instead of procedure, it compiled.
CREATE OR REPLACE function ilce_gtr
(
p_ilkodu number
)
RETURN VARCHAR2 AS
p_geridonen varchar2(1000);
begin
for rec in(SELECT ADI FROM ILCE WHERE Y_IL=p_ilkodu)
loop
p_geridonen := p_geridonen || '|' || rec.ADI;
end loop;
return p_geridonen;
end;
/
then i created xml via web method, it was successful.
#WebMethod
public String get_ilce (int p_ilkodu) {
Statement stmt=null;
ResultSet rs=null;
Connection conn=null;
String deger=null;
try {
conn= getConnection_test();
String query = "SELECT ILCE_GTR('" + p_ilkodu + "') FROM DUAL";
stmt = conn.createStatement();
rs = stmt.executeQuery(query);
while (rs.next()) {
deger = rs.getString(1);
}
} catch (Exception e) {
return "hata";
} finally {
try {
rs.close();
stmt.close();
conn.close();
} catch (SQLException e) {
return "hata";
}
}
return deger;
}
I want to do the same for inserting to database, can u help me?

#WebMethod
public String add_ilce (int yourInput) {
Statement stmt=null;
ResultSet rs=null;
Connection conn=null;
String deger=null;
try {
conn= getConnection_test();
String query = "INSERT INTO DUAL" + "(yourAttributeName)" +"VALUES (?)";
PreparedStatement preparedStmt = conn.prepareStatement(query);
preparedStmt.setString (1, yourInput);
preparedStmt.execute();
} catch (Exception e) {
return "hata";
} finally {
try {
rs.close();
stmt.close();
conn.close();
} catch (SQLException e) {
return "hata";
}
}
return deger;
}
EDIT: I suggest you to use DAO approach for such scenarios, check here: Data access object (DAO) in Java
EDIT: I edited the post now it must work as it should be, sorry I had some mistakes

web service didnt appear on localhost, there are others.
#WebMethod
public String add_ilce (String p_no, int p_tplm) {
Statement stmt=null;
ResultSet rs=null;
Connection conn=null;
String deger=null;
try {
conn= getConnection_test();
String query = "INSERT INTO DUAL" + "TEMP_TAHAKKUK_AG(ABONENO,TOPLAM)" +"VALUES ('p_no','p_tplm')";
stmt = conn.createStatement();
rs = stmt.executeQuery(query);
while (rs.next()) {
deger = rs.getString(1);
}
} catch (Exception e) {
return "hata";
} finally {
try {
rs.close();
stmt.close();
conn.close();
} catch (SQLException e) {
return "hata";
}
}
return deger;

ResultSet in Java

I need help creating a boolean check for a method I made. I basically want it to return true if they have the specified EnumRank, but it's not working. Any suggestions?
EDIT: Both values are stored in VARCHARS
Code:
public boolean hasRank(Player player, EnumRanks rank){
if (!MySql.checkConnection()){
return false;
}
try{
String query = "SELECT RANK FROM `user_ranks` WHERE UUID= '" + player.getUniqueId() + "';";
PreparedStatement statement = MySql.getConnection().prepareStatement(query);
ResultSet result = statement.executeQuery();
result.next();
return result.getBoolean(rank.getSQLName());
//return true - So I can use this method
}
catch (SQLException e){
//Nothing
}
return false;
}

Add the rank to the query, and you're using PreparedStatement so use bind parameters. You can use result.next() to check if the query returns a result and you should use the finally block to close your Statement and ResultSet (and Connection). And don't silently swallow Exception(s). Something like
public boolean hasRank(Player player, EnumRanks rank) {
if (!MySql.checkConnection()) {
return false;
}
Connection conn = null;
PreparedStatement statement = null;
ResultSet result = null;
String query = "SELECT RANK FROM `user_ranks` WHERE UUID=? AND RANK=?";
try {
conn = MySql.getConnection();
statement = conn.prepareStatement(query);
statement.setString(1, player.getUniqueId());
statement.setString(2, rank.getSQLName());
result = statement.executeQuery();
return result.next();
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (result != null) {
try {
result.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if (statement != null) {
try {
statement.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if (conn != null) {
try {
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
return false;
}

PostgreSQL: How do you insert rows of data with a loop into a database table?

How can you read & insert rows from a text file containing data in [x, y, z] form for example:
1 google com (separated by tabs)
into a database table (without having to insert every single line manually)?
I'm new at programming!

This is too long for a comment.
When loading data from a text file, I generally load into a staging table that consists of character column. Then, I can do validate the data, convert to the appropriate data types, and even reparse some columns, if necessary.
Admittedly, the Postgres COPY command often works quite well just reading in the data.
You would seem to have two options:
Load the data into a staging table and do the data cleansing there.
Read the data line-by-line in java and do the data cleansing there.
Because my SQL skills >> my java skills, it is a no-brainer which I would choose (SQL). But these would seem to be your most reasonable options.

Selecting a count from my database using Java and Netbeans

I have the following code:
try {
String sql = "SELECT COUNT(*) AS \"Jumlah\" FROM dokter";
ResultSet rs = connection.st.executeQuery(sql);
if(rs.next()){
abc = rs.getString("Jumlah").toString();
}
} catch (Exception e) {
System.out.println("\n Message: " + e.getMessage());
}
Why can't my ResultSet execute the given SQL?

Lose the alias, it's just an unnecessary complication. Just reference the ResultSet by the column's index:
try {
String sql = "SELECT COUNT(*) FROM dokter";
ResultSet rs = connection.st.executeQuery(sql);
if(rs.next()) {
abc = rs.getInt(1); // or getString(1) if you need it as a String
}
} catch (Exception e) {
System.out.println("\n Message: " + e.getMessage());
}

I suggest you use a PreparedStatement and a try-with-resources to close it (and your ResultSet). A count is not a String, and if you have a Connection connection then you might do something like
int count = 0;
try {
String sql = "SELECT COUNT(*) FROM dokter";
try (PreparedStatement ps = connection.prepareStatement(sql);
ResultSet rs = ps.executeQuery()) {
if (rs.next()) {
count = rs.getInt(1);
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (connection != null) {
try {
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}

PreparedStatement is closed
You can get this exception when you're trying to (re)use a PreparedStatement while it has been closed. Check the line number of the first line in the stacktrace. It should hint which PreparedStatement it is talking about. Then backtrack its use in the code and fix code accordingly.
Judging the flood of code you've posted, I suspect that it's the ps5 which is been created before a for loop and been closed inside the for loop. Here's an extract of relevance from your code:
ps5 = conn.prepareStatement(sqlQry);
for (MaterialRequestIssuanceVO movementvo : mlinelist) {
try {
ps5.setString(1, string);
ps5.executeUpdate();
} finally {
ps5.close(); // You're closing inside the loop!
}
}
The next iteration in the loop won't be able to reuse the same PreparedStatement anymore. The fix is obvious: close it after completion of the for loop.
try {
ps5 = conn.prepareStatement(sqlQry);
for (MaterialRequestIssuanceVO movementvo : mlinelist) {
ps5.setString(1, string);
ps5.executeUpdate();
}
} finally {
ps5.close();
}
That said, logging all exceptions as Info or doing only e.printStackTrace() and suppressing them and continuing the code flow isn't always a good idea. Log them as Error and then hard-throw thereafter.
} catch (Exception e) {
logger.error("Your message", e);
throw e;
}
Rethrowing isn't needed for exceptions during close, but logging them as Warn is useful.
Last but not least, consider refactoring the exceptionally large method block into separate and sensible methods (tasks) ;)
