I have an update query in a servlet. The syntax is is correct, but when I execute the query, nothing happens. The execution stays frozen and the command never ends. Minutes later the message "ADVERTENCIA: GRIZZLY0023: Interrupting idle Thread: http-thread-pool-8080(5)." is printed every couple of seconds
I have tried with:
con.stmt.executeUpdate ("SQL");
con.rset = con.stmt.executeQuery ("SQL");
and with PreparedStatement.
This is the query:
System.out.println(""
+ " UPDATE JSP_TABLE SET "
+ " field1 = '" + request.getParameter("input1") + "',"
+ " field2= '" + request.getParameter("input2") + "',"
+ " field3= '" + request.getParameter("input3") + "',"
+ " field4= '" + request.getParameter("input4") + "',"
+ " field5= '" + request.getParameter("input5") + "',"
+ " field6= '" + request.getParameter("input6") + "',"
+ " field7= '" + request.getParameter("input7") + "',"
+ " field8= '" + indicador + " VS " + request.getParameter("input8") + "',"
+ " field9= '" + request.getParameter("input") + " al " + request.getParameter("hasta9") + "'"
+ " WHERE ID_PK = " + request.getParameter("inputPK"));
All my Statements, ResultSets and Connections are closed at the end of use.
I have a second update which works fine.

Hope this help to find the answer.
PD: The small one run with no problems. the big one it's the problem.
EDIT:
This is conectar()
public conectar() {

System.out.println("Oracle JDBC driver loaded ok.");
conn = DriverManager.getConnection(params, user, password);
} catch (Exception e) {

Bill is almost certainly correct and you just have a lock on rows you're trying to update. You mentioned that 'the syntax is correct', which suggests you might have checked it directly in the database - e.g. with SQL*Plus or SQL Developer - and have not issued a rollback (or commit) in that session. Attempting to update the same rows from your code is then hanging waiting for the locks to be released.
If you can find the session where you ran the update manually, issue a rollback in it. If you can't, you can see which sessions are holding locks with a query like:
select vs.osuser, vs.process, vs.logon_time, vs.sid, vs.serial#, vs.program,
dl.lock_type, dl.mode_held, dl.blocking_others
from dba_locks dl
left join v$session vs on vs.sid = dl.session_id
where lock_type != 'Media Recovery'
and lock_type != 'Redo Thread';
While your code is running - and hung - you can see what's blocking it with something like:
select vsw.osuser, vsw.process, vsw.logon_time, vsw.sid, vsw.program,
dw.lock_type, dw.mode_held,
vsh.osuser, vsh.process, vsh.logon_time, vsh.sid, vsh.serial#, vsh.program
from dba_waiters dw
left join v$session vsw on vsw.sid = dw.waiting_session
left join v$session vsh on vsh.sid = dw.holding_session;
Or search for other examples, e.g. this. You need privileges to query the v$ performance views, and if you don't have them you may need DBA assistance. If you can't manually rollback the lock you might need DBA help to kill the locking session anyway.
You should really pay attention to the comments about parameterising your statements, too.

I have a JPA query with multiple joins and optional parameters , the query works fine if there is no multiple values sent in the status list parameter but if I send multiple values its giving exception as
"Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: An expression of non-boolean type specified in a context where a condition is expected, near ','.
Below is the query, could you please help
#Query(value = select distinct a.invn, a.accid, ac.accountCode, b.Fbusinesscode" +
", b.scode, i.invtype, d.dtid, d.did " +
" from INV.BINv a " +
"join READONLY.Fbusiness b on a.FbusinessId =b.FbusinessId " +
"join READONLY.Acc ac on a.accid=ac.accid " +
"join INV.Doc c on a.invid = c.invid " +
"join INV.Dstreq d on c.docid = d.docid " +
"join INV.dassoc e " +
"on d.dassocId = e.dassocId " +
"join BLNG.InvMType AS i on e.invtypeId = i.invtypeId "+
"where (?#{#requestdto.invoiceNumber } is null OR a.InvoiceEntityNumber = ?#{#requestdto.invoiceNumber}) and " +
" (?#{#requestdto.mod} is null OR i.InvTypeName = ?#{#requestdto.mod}) and " +
" (?#{#requestdto.getStatus} is null OR e.distrstttypecode in ?#{#requestdto.getStatus}) "
Something like this should do it:
#Query("select distinct a.invn, a.accid, ac.accountCode, b.Fbusinesscode" +
", b.scode, i.invtype, d.dtid, d.did " +
" from INV.BINv a " +
"join READONLY.Fbusiness b on a.FbusinessId =b.FbusinessId " +
"join READONLY.Acc ac on a.accid=ac.accid " +
"join INV.Doc c on a.invid = c.invid " +
"join INV.Dstreq d on c.docid = d.docid " +
"join INV.dassoc e " +
"on d.dassocId = e.dassocId " +
"join BLNG.InvMType AS i on e.invtypeId = i.invtypeId "+
"where (?#{#requestdto.invoiceNumber } is null OR a.InvoiceEntityNumber = ?#{#requestdto.invoiceNumber}) and " +
" (?#{#requestdto.mod} is null OR i.InvTypeName = ?#{#requestdto.mod}) and " +
" (?#{#requestdto.status?.size() ?: 0} = 0 OR e.distrstttypecode in ?#{#requestdto.status}) "
Note that in original query you specified requestdto.getStatus which should likely be just requestdto.status.

I just started using C# and I a have a textbox on a form. I want to display only numbers from ACCESS database, Like string stored in database is 12Kg but when I do update i should return only value i.e.12, I have searched but not getting any idea, I hope you can help me...
Query:
"Update Para Set PartNumber = '"+ txtPartNoL.Text + "', MacID = '" + cmb.SelectedValue.ToString() + "'"+" Para1 = '" + txtPara1L.Text + "', PType1 = '" + lblLPara1.Text + "'," + " val(LabourPara.Para4) = '" + txtPara4L.Text + "', PType4 = '" + lblLPara4.Text + "'," + " Qty = '" + txtQtyL.Text + "', PF = '" + txtPFL.Text + "', SF = '" + txtSFL.Text + "'," + " Amount = '" + txtAmt.Text + "'" + " WHERE QoNumber = '" + txtNo.Text + "' AND PartNumber = '" + txtPartNo.Text + "'";
You are updating everything as text, which can't be true for at least quantity and amount, so try:
sql = "Update Para Set PartNumber = '"+ txtPartNoL.Text + "', MacID = '" + cmb.SelectedValue.ToString() + "' " +
"Para1 = '" + txtPara1L.Text + "', PType1 = '" + lblLPara1.Text + "', " +
"LabourPara.Para4 = " + Val(txtPara4L.Text) + ", PType4 = '" + lblLPara4.Text + "', " +
"Qty = " + txtQtyL.Text + ", PF = '" + txtPFL.Text + "', SF = '" + txtSFL.Text + "', " +
"Amount = " + txtAmt.Text + " " +
"WHERE QoNumber = " + txtNo.Text + " AND PartNumber = '" + txtPartNo.Text + "'";
However, avoid this concatenating mess and - asap - go and learn how to use parameters.
I'm using a native query to get a specific resulset since there's a conflict when using LIMIT in JPA. When I call the method via spring-boot I get 1 row but when I execute the SQL command directly I get 5 rows. I think this is a JPA native query issue it's always returning 1 row.

I am using Spring Boot and PostgreSQL to create a table in which I want to insert the latest data from another table.
I was using H2 and everything was fine but when I migrated to PostgreSQL, the error "SELECT ... FROM must be followed by a reference to the table appeared e.g. SELECT * FROM table as FOO" .
However, when modifying my query with AS, I am still having the same error.
"CREATE TABLE IF NOT EXISTS EOD AS " +

Any idea how to solve this issue?
Many thanks in advance !
My report don´t accept the parameter.
I have created a parameter with "City" name.
In my code i want to full it:
ReportDocument crystalReport = new ReportDocument();
crystalReport.Load(Server.MapPath("CrystalReport.rpt"));
crystalReport.SetParameterValue("City", lblCiudad.Text);
viewer.ReportSource = crystalReport;
the problem is that the report doesnt filter with my parameter, show without it.
Solution with formula:
crystalReportViewer.SelectionFormula = "{Clientes.Nombre} = '" + nombreCliente + "' AND {Registros.Host} = '" + host + "' AND {Registros.Servicio} = '" + service + "' AND {Registros.Fecha} <= " + "DateTime(" + fF.Year.ToString() + "," + fF.Month.ToString() + "," + fF.Day.ToString() + ","+fF.Hour.ToString() + "," + fF.Minute.ToString()+","+fF.Second.ToString()+") AND {Registros.Fecha} >= " + " DateTime(" + fI.Year.ToString() + "," + fI.Month.ToString() + "," + fI.Day.ToString() + ","+fI.Hour.ToString() + "," + fI.Minute.ToString()+","+fI.Second.ToString()+")";
