How can I untruncate the HTML code to see the whole of it? It gets truncated with three dots at the end.

It's retuning a CLOB, and you're running this as a query.
If you double click the cell with the '...' in it, it should open to show the the entire contents.
I think it might be easier to see executing as as script.
Try this:
set long 1000000
set pagesize 0
clear screen
select dbms_sqltune.report_sql_detail(
sql_id => 'f34thrbt8rjt5',
type => 'ACTIVE',
report_level => 'ALL') as report
from dual;
Execute as script (F5) is the 2nd execute button. You'll see the output below -
If you have the SQL statement for your SQL_ID, you can also ask for the SQL Tuning Advisor Report directly there in the SQL Worksheet -
Note that these features require Enterprise Edition of the database AND the Tuning pack to be licensed.

I have created DELPHI database application which will use DBX TSQLConnection component to connect to Oracle database (19c version).
I'm getting access violation error , When i call oracle listagg function (SQLQuery1.open --in this line).
When i debugged , i got the error in below object file,
FileName : Data.DBXDynalink.pas
Function : function TDBXDynalinkReader.DerivedNext: Boolean;
Error Line : DBXResult := FMethodTable.FDBXReader_Next(FReaderHandle);
Actual Error : Access violation at address 04FD6CC2 in module 'dbxora.dll'. Read of address 00000004
Below is my code ,
...SQLQuery1 initialization....
SQLQuery1.CommandText := Trim(memoSQLText.Lines.Text); // Assigning query
SQLQuery1.Open; // Exactly on this line i'm getting error
if SQLQuery1.RecordCount > 0 then
....Do something here....
Note : Same query is executing in other versions which are all below to Oracle version 19C (19.3)
IDE version used for application development : DELPHI XE3 (i have checked with DELPHI 10.1 Berlin also)
DB version : Oracle 19C (19.3)
Steps to reproduce :
// 1.Execute below queries in order to create testing data ,
create table myuserlist(myuser varchar2(10));
Insert into myuserlist(myuser) values('karthik');
Insert into myuserlist(myuser) values('aarush');
Insert into myuserlist(myuser) values('yuvan');
// 2.Try to open the below mentioned query using TSQLConnection and TSQLQuery
select listagg(a.myuser, ', ') within group (order by a.myuser) as myusernames from myuserlist a

Help me to resolve this issue.
I am trying to find records ending in ~0000 such as ABC~0000
but everything I try doesn't seem to work. Some examples:
and left (mfr_part_number, 4) = 'ABC~' -- finds nothing
and left (mfr_part_number, 3) = 'ABC' -- finds stuff
AND RIGHT(MFR_PART_NUMBER, 4) = '0000' -- finds nothing
AND RIGHT(MFR_PART_NUMBER, 5) = '~0000' -- finds nothing
and DbFunctions.Like(MFR_PART_NUMBER,'%0000') -- suggested elsewhere, but not recognized in MSSMS.
I am using:
SQL Server Management Studio 15.0.18206.0
Microsoft Analysis Services Client Tools 15.0.1567.0
Microsoft Data Access Components (MDAC) 10.0.18362.1
Microsoft MSXML 3.0 6.0
Microsoft .NET Framework 4.0.30319.42000
Operating System 10.0.18363
Thanks!
Are you using all of those AND statements in your WHERE clause? If so, that would cause nothing to return if there's no data that matches all criteria.
Try
SELECT column1, column2...
FROM yourdb
WHERE MFR_PART_NUMBER LIKE '%0000'
I have two table definitions in DDS, compiled into *FILE objects and filled with data:
Kunpf:
A UNIQUE
A R KUNTBL
A FIRMA 60A ALWNULL
A KUNR 5S 0B
A KUNID 4S 0B
A K KUNR
A K KUNID
Kunsupf:
A R KUNSUTBL
A KUNID R B REFFLD(KUNID KUN/KUNPF)
A
A SUCHSTR 78A
A K SUCHSTR
A K KUNID
I'm using the following statement in interactive SQL (STRSQL):
SELECT DISTINCT FIRMA, KUNR FROM KUN/KUNPF
LEFT JOIN KUN/KUNSUPF ON (KUNPF.KUNID = KUNSUPF.KUNID)
WHERE SUCHSTR LIKE 'Freiburg%'
ORDER BY FIRMA
FOR READ ONLY
Everytime I execute this statement, I'm getting a considerable delay until the answer screen opens up. Beforehand a message is shown, stating that a temporary access path is being created.
How can I find out which/how this temporary access path is created? My goal is to have this access path made permanent so it doesn't need to be rebuilt with every invocation of this query.
I searched the net (especially the IBM site) but what I found out was mostly for DB2 on z/OS. The F4-Prompting facility in STRSQL doesn't provide help: I was searching for something like EXPLAIN SELECT from MySQL. The IBM DB2 Advanced Functions and Administration PDF states that there's a debug mode but it seems that it is only available from some (old) Windows tool I don't remember to have.
I'm utilizing V4R5, if this is relevant.
to see the access path on the green screen...
strdbg
strsql
run your statement
exit f3
enddbg
dspjoblog
the access path messages are at the bottom of the log f10 f18 afaik
v4r5??? That's like 20 years old...
For the IBM i, the "Run SQL Scripts" component of the old Client Access For Windows iSeries Navigator component and the new Access Client Solutions (ACS) contains Visual Explain (VE).
Luckily it seems though it was added to v4r5
http://ibmsystemsmag.com/ibmi/administrator/db2/database-performance-tuning-with-visual-explain/
Just start iNav, right click on "Database" and select "Run SQL Scripts"
Paste your query there and click "Visual Explain" -->"Run and Explain"
(or the corresponding button)
Optionally, in green screen.
Do a STRDBG to enter debug mode, F12 to continue and then go into STRSQL. The Db optimizer will then output additional messages into the joblog giving you more information about what it is doing..
I'm looking to create a procedure that helps with debugging specific variables, and for the sake of re-usability I'd like to store it in it's own procedure and pass in the specific variable when needed such as
debugz(var_x);
and the debug procedure would do the following -
PROCEDURE debugz (var_x VARCHAR2(1000))
AS
BEGIN
DBMS_OUTPUT.put_line ('Variable value: '|| var_x || ' | Line number: ' || $$plsql_line ||' | Unit: '|| $$plsql_unit);
END;
The problem is, I want the PL/SQL line number and PL/SQL unit to be based off of where the procedure call originates, i.e. the line/unit of "debugz(var_x);". Is there anyway for debugz to output that line number without passing in additional information?
Check out DBMS_UTILITY.FORMAT_CALL_STACK
You may need/want to parse the output depending on your exact requirements, but may be a good place to start.
Oracle 10g onwards.
Also note DBMS_UTILITY.FORMAT_ERROR_BACKTRACE and DBMS_UTILITY.FORMAT_ERROR_STACK for error handling.
There is a very good debugging package unit called debugf which provides good functionality
The debug file contains information such as session id,date and time,packages being called and the line number of each debug message and the debug message itself
Example usage is given below
This is used to intialize the debug, the first parameter 'ALL' meaning all modules(can be function,procedure or package etc) and SYSTEM meaning the schema i want to debug
debug.init(p_modules => 'ALL',p_file =>'C:\debugf123\temp\test.txt',p_user =>'SYSTEM',p_show_date => 'YES',p_date_format =>'DD/MM/YYYY HH24:MI:SS',p_name_len => 30,p_show_sesid => 'YES');
This one works like printf in C and the maximum you can give is 10 parameters where v_word1 is a parameter
debug.f('the first is %s',v_word1);
This is same as debug.f but here you can give more than 10 parameters
debug.fa('the third is %s and %s',debug.argv(v_word1,v_amount));
The source code for this package is available at
http://gerardnico.com/wiki/database/oracle/debugf
OWA_UTIL.WHO_CALLED_ME(
owner OUT VARCHAR2,
name OUT VARCHAR2,
lineno OUT NUMBER,
caller_t OUT VARCHAR2);
Have you tried remote debugging? Here's how you can do it in SQL Developer:
1) Reference:
http://sueharper.blogspot.ca/2006/07/remote-debugging-with-sql-developer_13.html
2) User privileges:
grant EXECUTE on DBMS_DEBUG_JDWP to USERXX;
grant DEBUG CONNECT SESSION to USERXX;
grant DEBUG ANY PROCEDURE to USERXX;
3) Set Remote Debug on USERXX connection in SQL Developer:
Port: 80 (use 4000 if not blocked by firewall)
Local Address: IP address of your local machine
4) Compile code (package, procedure or function) in USERXX in SQL Developer for debug
5) Set breakpoints in code
6) On the remote (this could be your application invoking the PLSQL code):
before invoking the PLSQL code run/include the following:
DBMS_DEBUG_JDWP.CONNECT_TCP( 'IP address in 3', port in 3 ) when this is run SQL developer will switch to debug mode.
7) Run application or invoke procedure from remote as USERXX
8) SQL developer stops at first breakpoint, step into, view/change values and etc.
This error showed when I tried to select on an empty table in MS SQL Server 2005: "either BOF or EOF is True, or the current record has been deleted". I have used TADOConnection and TADODataSet in Delphi 5 to connect and retrieve data from the database.
Conn := TADOConnection.Create(nil);
DataSet := TADODataSet.Create(nil);
Conn.ConnectionString := 'Provider=SQLOLEDB.1;Password=sa;' +
'Persist Security Info=True;' +
'User ID=user;Initial Catalog=mydb;' +
'Data Source=MYPC\SQLEXPRESS;' +
'Use Procedure for Prepare=1;' +
'Auto Translate=True;Packet Size=4096;' +
'Workstation ID=MYPC;' +
'Use Encryption for Data=False;' +
'Tag with column collation when possible=False';
Conn.LoginPrompt := False;
Conn.Open;
DataSet.Connection := Conn;
DataSet.CommandText := 'SELECT * FROM MYTABLE';
DataSet.Open;
DataSet.Free;
Conn.Free;
Is there a way to check if a database table is empty without incurring such error?
This error originally occured with an update to MDAC_TYP (to 2.6 from memory). According to an old Borland advisory
"This is a bug in the SQL Server provider. Set
CursorLocation = clUseClient to eliminate the error."
There was a ADOExpress patch available from Borland, but the link doesn't work. Embarcadero now host it here: ftp://ftpd.embarcadero.com/pub/delphi/devsupport/updates/adoexpress/d5adoupdate2.exe(Thanks for the official link Jeroen!)
I would recommend downloading and installing all patches listed on the Embarcadero site, assuming you can find them.
Download the ADO update for Delphi 5 here: ftp://ftpd.embarcadero.com/pub/delphi/devsupport/updates/adoexpress/d5adoupdate2.exe
Make sure you also have the regular update installed:
English Enterprise
English Professional
English Standard
There are more updates (Corba, original ADO install) and languages (French, German), but these should get you going.
There also used to be a http://info.borland.com/devsupport/delphi/download_files/zlibupdate.zip, but it is not on the ftpd servers.
--jeroen
It was long time agom but I recall that this problem in Delphi 5 resolves by Delphi update. Early version has serious problems with ADO components
P.S. Also I see that your code uses not typical runtime creation of components and does not use some container like data module or form (not good usually) for visual work with components. Also sometimes useful run simple queries via adoConnection.execute. If you do not use visual components, handling of ADO's Recordset object is much the same as Delphi's AdoDataset.
Since I spent a whole day on this, here is a wrap up of what I did in the end.
Delphi 5 Pro Installation with ADO Express
Uninstall Delphi 5, also deleted installation directory
Install Delphi 5 Pro (I only have a German Delphi Pro edition available)
Install Delphi 5 Pro Update (I used the German update)
Install Delphi 5 ADO Express
Install Delphi 5 ADO Express Update Pack 1
Install Delphi 5 ADO Express Update Pack 2
And the download links (many thanks again Jeroen Wiert Pluimers):
