sqlite3:Unable to close due to unfinalised statements - exception

I have two sqlite connections and execute like below(CMyDatabase is a derived class of sqlite3):
CMyDatabase* dbConnection1 = new CMyDatabase;
dbConnection1->OpenDataBase(CQCommon::GetModulePath() + L"test.db");
CMyDatabase* dbConnection2 = new CMyDatabase;
dbConnection2->OpenDataBase(CQCommon::GetModulePath() + L"test.db");
dbConnection2->BeginTrans();
CString updateStr("update ImageAlbumEntry set ImageID = 2 where ID = 1;");
dbConnection2->ExecNoQuery(updateStr);
CString queryStr("select ImageID from ImageAlbumEntry where ID = 1;");
CppSQLite3Query queryResult;
dbConnection2->ExecQuery(queryStr, queryResult);
cout<<queryResult.getIntField(0)<<endl;
dbConnection2->EndTrans(TRUE);
dbConnection2->CloseDataBase();
dbConnection1->CloseDataBase();
Now when I invoke dbConnection1->CloseDataBase(). I met with the error stated as 'Unable to close due to unfinalised statements'. Can anyone explain the reason and resolve method of the problem? Thank you!

Depends on which wrapper you are using. I'm guessing you are using one similar to cppSQLite3
If that is true, then you need to issue a CppSQLite3Query::finalize command to to tell sqlite3 that you are done with your query.
From the sqlite3 documentation here
sqlite3_finalize()
This routine destroys a prepared statement created by a prior call to sqlite3_prepare(). Every prepared statement must be destroyed using a call to this routine in order to avoid memory leaks.

Why am I getting error 3078 on my SELECT query?

I've started to try and write some VBA to execute some queries and I've got stuck at the first hurdle. This is giving an error 3078 which apparently means it can't find the table or query. The table definitely exists and is spelt properly. Indeed the SQL runs fine - I tested it. What am I doing wrong?
Public Function Tester()
str_tbl = "tblGames_atp"
str_mkvrec = "SELECT * FROM " & str_tbl
dbl_fs_pct = DSum("FS", str_mkvrec)
End Function
Cannot reference SQL statement in domain aggregate function, not even a variable set to that statement. Must reference table or query object name. Could reference variable with name string but variable not really needed in this code. If you want function to return a value to calling source, then need to set function value.
Public Function Tester()
Tester = DSum("FS", "tblGames_atp")
End Function

ssrs ORA_01008:NOT ALL VALIABLE BOUNDED [duplicate]

I have come across an Oracle problem for which I have so far been unable to find the cause.
The query below works in Oracle SQL developer, but when running in .NET it throws:
ORA-01008: not all variables bound
I've tried:
Changing the Oracle data type for lot_priority (Varchar2 or int32).
Changing the .NET data type for lot_priority (string or int).
One bind variable name is used twice in the query. This is not a problem in my
other queries that use the same bound variable in more than one
location, but just to be sure I tried making the second instance its
own variable with a different :name and binding it separately.
Several different ways of binding the variables (see commented code;
also others).
Moving the bindByName() call around.
Replacing each bound variable with a literal. I've had two separate variables cause the problem (:lot_pri and :lot_priprc). There were some minor changes I can't remember between the two. Changing to literals made the query work, but they do need to work with binding.
Query and code follow. Variable names have been changed to protect the innocent:

Why is Oracle claiming that not all variables are bound?
I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.
By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.
Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.
The correct way is to set the BindByName property of OracleCommand to true as below:
var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;
You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post
I found how to run the query without error, but I hesitate to call it a "solution" without really understanding the underlying cause.
This more closely resembles the beginning of my actual query:
-- Comment
-- More comment
SELECT rf.flowrow, rf.stage, rf.process,
rf.instr instnum, rf.procedure_id, rtd_history.runtime, rtd_history.waittime
FROM
(
-- Comment at beginning of subquery
-- These two comment lines are the problem
SELECT sub2.flowrow, sub2.stage, sub2.process, sub2.instr, sub2.pid
FROM ( ...
The second set of comments above, at the beginning of the subquery, were the problem. When removed, the query executes. Other comments are fine.
This is not a matter of some rogue or missing newline causing the following line to be commented, because the following line is a SELECT. A missing select would yield a different error than "not all variables bound."
I asked around and found one co-worker who has run into this -- comments causing query failures -- several times.
Does anyone know how this can be the cause? It is my understanding that the very first thing a DBMS would do with comments is see if they contain hints, and if not, remove them during parsing. How can an ordinary comment containing no unusual characters (just letters and a period) cause an error? Bizarre.
You have two references to the :lot_priprc binding variable -- while it should require you to only set the variable's value once and bind it in both places, I've had problems where this didn't work and had to treat each copy as a different variable. A pain, but it worked.
On Charles' comment problem: to make things worse, let
:p1 = 'TRIALDEV'
via a Command Parameter, then execute
select T.table_name as NAME, COALESCE(C.comments, '===') as DESCRIPTION
from all_all_tables T
Inner Join all_tab_comments C on T.owner = C.owner and T.table_name = C.table_name
where Upper(T.owner)=:p1
order by T.table_name
558 line(s) affected. Processing time: 00:00:00.6535711
and when changing the literal string from === to ---
select T.table_name as NAME, COALESCE(C.comments, '---') as DESCRIPTION
[...from...same-as-above...]
ORA-01008: not all variables bound
Both statements execute fine in SQL Developer. The shortened code:
Using con = New OracleConnection(cs)
con.Open()
Using cmd = con.CreateCommand()
cmd.CommandText = cmdText
cmd.Parameters.Add(pn, OracleDbType.NVarchar2, 250).Value = p
Dim tbl = New DataTable
Dim da = New OracleDataAdapter(cmd)
da.Fill(tbl)
Return tbl
End Using
End Using
using Oracle.ManagedDataAccess.dll Version 4.121.2.0 with the default settings in VS2015 on the .Net 4.61 platform.
So somewhere in the call chain, there might be a parser that is a bit too aggressively looking for one-line-comments started by -- in the commandText. But even if this would be true, the error message "not all variables bound" is at least misleading.
The solution in my situation was similar answer to Charles Burns; and the problem was related to SQL code comments.
I was building (or updating, rather) an already-functioning SSRS report with Oracle datasource. I added some more parameters to the report, tested it in Visual Studio, it works great, so I deployed it to the report server, and then when the report is executed the report on the server I got the error message:
"ORA-01008: not all variables bound"
I tried quite a few different things (TNSNames.ora file installed on the server, Removed single line comments, Validate dataset query mapping). What it came down to was I had to remove a comment block directly after the WHERE keyword. The error message was resolved after moving the comment block after the WHERE CLAUSE conditions. I have other comments in the code also. It was just the one after the WHERE keyword causing the error.

Here is what the dataset parameter mapping screen looks like.
It's a bug in Managed ODP.net - 'Bug 21113901 : MANAGED ODP.NET RAISE ORA-1008 USING SINGLE QUOTED CONST + BIND VAR IN SELECT' fixed in patch 23530387 superseded by patch 24591642
Came here looking for help as got same error running a statement listed below while going through a Udemy course:
INSERT INTO departments (department_id, department_name)
values( &dpet_id, '&dname');
I'd been able to run statements with substitution variables before. Comment by Charles Burns about possibility of server reaching some threshold while recreating the variables prompted me to log out and restart the SQL Developer. The statement ran fine after logging back in.
Thought I'd share for anyone else venturing here with a limited scope issue as mine.
I'd a similar problem in a legacy application, but de "--" was string parameter.
Ex.:
Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008
Changing address parameter value '--' to '00' or other thing, works.

Insert query failing when using a parameter in the associated select statement in SQL Server CE

INSERT INTO voucher (voucher_no, account, party_name, rece_amt, particulars, voucher_date, voucher_type, cuid, cdt)
SELECT voucher_rec_no, #account, #party_name, #rece_amt, #particulars, #voucher_date, #voucher_type, #cuid, #cdt
FROM auto_number
WHERE (auto_no = 1)
Error:
A parameter is not allowed in this location. Ensure that the '#' sign is in a valid location or that parameters are valid at all in this SQL statement.
I've just stumbled upon this whilst trying to fix the same issue. I know it's late but, assuming that you're getting this error when attempting to execute the query via .net, ensure that you are setting the SqlCeParameter.DbType - if this is not specified, you get the exception you listed above.
Example (assume cmd is a SqlCeCommand - all the stuff is in the System.Data.SqlServerCe namespace):
SqlCeParameter param = new SqlCeParameter();
param.ParameterName = "#SomeParameterName";
param.Direction = ParameterDirection.Input;
param.DbType = DbType.String; // this is the important bit to avoid the exception
param.Value = kvp.Value;
cmd.Parameters.Add(param);
Obviously, you'd want to set the DB type to match the type of your parameter.

jdbc mysql batch prepared call keeps only the last result set

I have a stored procedure call
call get(id);
in my database that would return a single row in a ResultSet object (it is basically a very long SELECT statement inside). Now in Java, I have a
int[] ids = {1,2,3}
and for each id in the list I want to call the stored procedure to get the record. So eventually I want a list of records corresponding to each id in ids. I attempted
Connection conn = ...;
PreparedStatement ps = conn.prepareCall("call get(?)");
for(int id : ids) {
ps.setInt(1, id); ps.addBatch();
}
ps.executeBatch();
with only the result of call
get(3);
is kept.
I also tried to move the SELECT statement directly as a String in Java, so it looks like
String stmt = "SELECT ... WHERE id=?"
PreparedStatement ps = conn.prepareStatement(stmt);
... // the for loop same as above
ps.executeBatch();
with a "Can not issue executeUpdate() for SELECTs". I tried
ps.executeQuery();
as the last line, but it also only has the result of the last SELECT.
I want to avoid a for loop that executes a SELECT a time because transferring data from the database to my computer has a very heavy overhead.
Can anyone help? Thank you in advance!
EDIT: I read Running the same select query multiple times with different parameters: Mysql , but in my case it is a little bit different, because in my select statement the id actually needs to be referenced several times; the code looks like this
SELECT * FROM
(SELECT ... FROM ... WHERE id=? AND ...),
(SELECT ... FROM ... WHERE id=? AND ...);
so it seems impractical to use the IN method. Also I have another call
call get2(aid, userId)
and a list of {{1, 1000}, {2, 2000}} which also does not fit this issue. Can anyone help? Thank you!

error handling when performing 2 mysql queries

I have constructed a function where two queries are performed. Both of these queries insert data into two separate tables, data that is related to the registration of a user.
In one table things like username,password are held and in the other table stuff like address, phone etc...
Here is the function:
function register_biz_user($post,$connection)
{
$name=$connection-> real_escape_string($_POST['name']);
$lastname= $connection->real_escape_string($_POST['lastname']);
$pass_hashed = password::hash($_POST['password']);
$passwd= $connection->real_escape_string($pass_hashed);
$buztype= $connection->real_escape_string($_POST['buztype']);
$usertype= $connection->real_escape_string($_POST['usertype']);
$address= $connection->real_escape_string($_POST['address']);
$city= $connection->real_escape_string($_POST['city']);
$municipality= $connection->real_escape_string($_POST['municipality']);
$url= $connection->real_escape_string($_POST['wwwaddress']);
$email= $connection->real_escape_string($_POST['e-mail']);
$phone= $connection->real_escape_string($_POST['phone']);
$hash =$connection->real_escape_string(md5( rand(0,1000) )) ;
$connection->set_charset("utf8");
$result1 = $connection->query("insert into users values
(NULL,'" .$name. "','" .$lastname . "','".$email."','". $passwd."','".
$hash."','". $usertype."')");
if (!$result1) {
throw new Exception('error');
return false;
}
else{$result2=$connection->query("insert into business_users values
('".$connection->insert_id."','" .$address."','".$url ."','".$phone.
"','".$city. "','".$municipality. "','".$buztype. "')");
}
if(!$result2)
{ throw new Exception('error');
return false;}
return true;
}
And here is my problem:
If you look at the code you might notice that there is the problem that the 1st query runs without problem and the second throws an exception or vice verca.
My point is that there is the danger that the db WILL have ONLY partial data of the registered user. The goal is that either both queries run successfully or none runs.
How I must write the above code such that I can achieve the above statement?
I hope I was clear enough.
Use transactions: http://dev.mysql.com/doc/refman/5.0/en/commit.html
BEGIN
... queries ...
COMMIT or ROLLBACK
Note: "or vice verca" - that's not possible. In that case the 2nd query never gets executed.
Note2:
what's $post? seems to be unused.
why don't you use prepared statements? escaping everyhing is very error prone.
why do you have a procedural interface, passing $connection? you should have objects which know about the database connections... you have mixed code for at least 3 different layers... not necessary bad if you plan to create write-once-get-rid-of-code but probably not a good idea for a project which you have to maintain for months/years.
