Unable to use PL/SQL Debugger, Production SQL Developer on OS X 10.4
I am still unable to use the PL/SQL debugger in OS X.
When I start the debugger I get this:
Connecting to the database testdb.
Executing PL/SQL: ALTER SESSION SET PLSQL_DEBUG=TRUE
Executing PL/SQL: ALTER SESSION SET PLSQL_COMPILER_FLAGS=INTERPRETED
Executing PL/SQL: CALL DBMS_DEBUG_JDWP.CONNECT_TCP( '172.16.81.33', '49260' )
Debugger accepted connection from database on port 49260.
Processing 56 classes that have already been prepared...
Finished processing prepared classes.
Then nothing, it never gets to a breakpoint or does anything else. It works just fine on my Win XP box, just not on my OS X machine.
Anyone having this problem or have any tips to try? I've never gotten the debugging to work on any Raptor or SQL Developer build in OS X. However, JDeveloper debugging works just fine on this mac.
I am also experiencing this problem.
Perhaps the following excerpt from the console can shed some light on the problem.
Exception in thread "JPDA Event Processor" java.lang.VerifyError: (class: com/sun/tools/jdi/OracleReferenceTypeImpl, method: <init> signature: (Lcom/sun/tools/jdi/ReferenceTypeImpl;)V) Bad access to protected data

Mac - SQLDev 1.5 - Unable to use carriage return/enter in SQL Worksheet
This morning I brought up SQLDeveloper (1.5). I connected to a database. Started typing in a query and the carriage return (or enter) does not work. If I go to a menu or the list of files, it does work. Just not in the SQL Worksheet. I removed the application and re-installed. Still the same. I do not see this behavior in any other application or situation. Just within the SQL Worksheet of SQLDeveloper.
As a check, I did exit all other applications, rebooted, and tried again. Still no joy. I have the latest updates of Leopard and SQLDeveloper. I am guessing it is not using the latest Java but rather what was deployed with SQLDeveloper.
Any thoughts on how I could lose these two keys? There is no change to the system preferences for the keyboard. There is no setup to have the carriage return or enter key be mapped to anything else.
Very odd. I tried looking around the application and only in the SQL Worksheet does it not work.
Any ideas?
EricAhh, I was pulling my hair out over this since last week (on a PC, not a Mac). I just couldn't figure out why I could no longer add a line feed on the SQL worksheet when I hadn't changed anything at all.
Anyway, I still have no idea how the settings got changed, but resetting to defaults did the trick. Thanks! -
I have recently installed SQL Server 2008. When I try to execute a query against an Access database, I receive this debugging error:
"Unable to start Transact-SQL debugger. The Transact-SQL debugger does not support SQL Server 2005 or earlier versions of SQL Server. (SQLEditors)"
Nor will the query execute; I get a transport-level error 0. Any thoughts?Hi Davidmhjr,
>>Unable to start the Transact-SQL Debugger. The Transact-SQL Debugger does not support SQL Server 2005 or earlier versions of SQL Server. (SQLEditors).
Have you tried to restart the server once you have installed SQL Server 2008? As Naomi N mentioned please check the version of SQL Server you are using.
If you tried to connect to SQL Server 2005 from SQL Server 2008 SSMS, you would not be able to debug and get this error, it happens because T-SQL debugger includes both server-side and client-side components. The server-side debugger components are installed
with each instance of the SQL Server 2008 Database Engine. The client-side components are installed when you install the SQL Server 2008 client-side tools.
So it works with SQL Server 2008 only so far. Another way is you can triy to use SQL Server 2005 SSMS to connect to SQL Server 2005.
More information about configuration requirement to run T-SQL debugger as below, please refer:
There are no configuration requirements to run the Transact-SQL debugger when SQL Server Management Studio is running on the same computer as the instance of the SQL Server Database Engine. However, to run the Transact-SQL debugger when SQL Server Management
Studio is running on a different computer from the instance of the Database Engine, you must enable program and port exceptions by using the Windows Firewall Control Panel application on both computers.
On the computer that is running the instance of the Database Engine, in Windows Firewall, specify the following information:
•Add TCP port 135 to the exceptions list.
•Add the program sqlservr.exe to the exceptions list. By default, sqlservr.exe is installed in C:\Program Files\Microsoft SQL Server\MSSQL10.InstanceName\MSSQL\Binn, where InstanceName is MSSQLSERVER for the default instance, and the instance name for
any named instance.
•If the domain policy requires network communications to be done through IPsec, you must also add UDP port 4500 and UDP port 500 to the exception list.
On the computer that is running SQL Server Management Studio, in Windows Firewall, specify the following information:
•Add TCP port 135 to the exceptions list.
•Add program ssms.exe (SQL Server Management Studio) to the exceptions list. By default, ssms.exe is installed in C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE.
Hope it is helpful.

Unable to use backspace key in SQL Developer
hi
I am unable to use backspace or arrow keys in SQL worksheet using SQL developer.
Can any one help me out...?
You can also contact me on [email protected]
regards
AhsanHi,
to give a worst case. I downloaded actual releases for JDeveloper and SQLDeveloper for MacOS and on my Mac this case is totally unsolved. I tried to check he settings within the preferences.xml but no "googled" solution works to get SPACE and BACKSPACE to work.
I will try the older versions.
I previously used my migrated versions from my older Linux system and everything worked fine. Installing the integrated MacOS versions is fine but using the linux way (using the shell command) seems to work. Hope this will help to find the bug within the packages.
Bye,

Unable to use fn-bea:execute-sql() in an XQuery in Workspace Studio 1.1
When we create an XQuery file in Workspace Studio 1.1 (ALSB 3.0), we are unable to use fn-bea:execute-sql(). It throws an error saying "unknown function". It doesnt allow us to publish the XQuery file to ALSB instance due to the "unknown function" error. However if we directly upload this file to ALSB console, it accepts it and the execute-sql function also works grrat. Can you please let us know if we have to configure anything on the Workspace studio to be able to use XQuery Extensions for Service Bus ? Or can you please let us know if we should declare any namespace in the XQuery file to use fn-bea:execute-sql() in Workspace studio ?
It sounds like a bug. Can you please contact bea support?

Using Package to produce pl/sql function body returning sql query Report
I have existing code that we want to use in building reports in APEX. We are needing to modify it slightly to handle some new requirements, but would like to use them in reports based upon SQL query (pl/sql function body returning sql query) functionality.
Any suggestions as how to call these in an APEX report region?
Thank you,
Tony Miller
UTMB/EHNHi Tony-
I am also v new to Apex and you may have answered a question I was in search of. I, however, now have a couple more. First a bit of background-- Like in your situation, my college has a lot of existing code (400 +) that we need to get into Apex. The majority of this canned code contains one/both: 1) many lines, sometimes containing multiple select statements 2) imbedded create table & view statements (temp user owned). Up until reading your post, I was unable to figure out an easy way of getting this existing code into the product. Thanks. Now the questions, do you know how I would go about dealing with the create tables/views. I've read some posts on this forum which suggest temporary tables being unstable in this environment. Also, do you know if there's a size limitation when passing sql code via a function?
As you may/may not be able to tell, I'm a bit lost right now... so any info you can provide would be appreciated. Thanks.

Why named parameter can't be used multiple times in PL/SQL block in JDBC
with the following PL/SQL block, when I run int in JDBC, I get an error,
it says, The number of parameter names does not match the number of registered parameters.
if all named parameters are used only once, then my program works fine.
My old program uses Oracle Forms to run the attached PL/SQL block correctly, I just want to run them in JDBC without more efforts, I don't want to rewrite all PL/SQL blocks.
Does oracle driver support this case? why the PL/SQL block can work in Oracle Forms but failed in JDBC?
Can we have an another solutions to avoid rewriting the PL/SQL block to stored procedure?
if I use following SQL:
BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;
, Using java program:
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
in the coding, only "q" registered, I got:
java.sql.SQLException: The number of parameter names does not match the number of registered praremeters at oracle.jdbc.driver.OracleSql.setNamedParameters(OracleSql.java:314) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10096) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:28)
now, tried to register 3 indexes, changed fragments are below.
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.registerOutParameter(2, Types.VARCHAR); stmt.registerOutParameter(3, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
now error changed to:
java.sql.SQLException: ORA-01006: bind variable does not exist at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:457) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:400) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:926) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:476) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:200) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:543) at oracle.jdbc.driver.T4CCallableStatement.doOall8(T4CCallableStatement.java:208) at oracle.jdbc.driver.T4CCallableStatement.executeForRows(T4CCallableStatement.java:1416) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1757) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4372) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now tried register only 1 position like below,
CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute();
, it says:
java.sql.SQLException: Missing IN or OUT parameter at index:: 2 at oracle.jdbc.driver.OraclePreparedStatement.processCompletedBindRow(OraclePreparedStatement.java:2177) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4356) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now let try a OK case, which use all named parameters only once. coding like below, SQL and Java listed below.
BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; EXCEPTION WHEN NO_DATA_FOUND THEN NULL; END;
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.registerOutParameter("s", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); System.out.println("S :" + stmt.getString("s")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the case give us the following output:
Q :A R :null S :Y
2nd part, I also tried another scheme, to use 'execute immediate', test code attached below, it also have errors.
begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;
, Java Code:
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is, we can find when parameter 'q' is IN OUT mode, we can't get its final value:
Q :null R :Z
, now I tried my workaround, it works fine by using a temporary variable, now my named parameter is split to 2 roles, one is for IN, another is for OUT, now I can get final out value.
declare q clob; r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;
, my test java code,
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="declare q clob;r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(3, Types.VARCHAR); stmt.registerOutParameter(4, Types.VARCHAR); stmt.setString(1, "A"); stmt.setString(2, "A"); stmt.execute(); System.out.println("Q :" + stmt.getString(3)); System.out.println("R :" + stmt.getString(4)); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is expected,
Q :Y R :Z

Edited by: jamxval on 2013-3-26 17:57 (UTC +08), Adjust code styleHi, thanks for your response, now I see, the named parameter is for stored procedure only, for PL/SQL block we name it placeholder name.
After cast my java.sql.CallableStatement to oracle.jdbc.OracleCallableStatement, I can find setStringAtName,
now, I have only one question:I can't find corresponding methods for registerOutputParameter, how we fetch output value?
I tried to callableStatement.getString("q"); it reports errors, but there are no ordinal binding in my source code, does placeholder names doesn't support OUT mode?
Java:
CallableStatement stmt = con.prepareCall("BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;");
oracle.jdbc.OracleCallableStatement call = (oracle.jdbc.OracleCallableStatement) stmt;
call.registerOutParameter("q", Types.VARCHAR);
call.registerOutParameter("r", Types.VARCHAR);
call.registerOutParameter("s", Types.VARCHAR);
call.setStringAtName("q", "A");
call.setStringAtName("r", "A");
call.setStringAtName("s", "A");
call.execute();
System.out.println("Q :" + call.getString("q"));
</Java>
<output>
java.sql.SQLException: 不允许的操作: Ordinal binding and Named binding cannot be combined!

at oracle.jdbc.driver.OracleCallableStatement.getString(OracleCallableStatement.java:2834)
at RunPLSQLBlock.main(RunPLSQLBlock.java:33)
</output>by the way, in my below-mentioned SQL 'problematic', when my code uses 'execute immediate' and use placeholder names in IN OUT mode, we always get NULL value (i.e. ':q'), but we can get final value of ':r' when ':r' is OUT mode only; now I get a workaround attached in below-mentioned 'my workaround' block, which split the IN OUT roles to 2 parts, it can work now;
It seems that the difference between 'problematic' and 'my workaround' imply that there are something work unexpectedly when the driver process the placeholder names, because 'my workaround' and ':r in problematic case' make sure the 'execute immediate' returned output values correctly, unluckly driver layer can't get return values.

execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;'

But it is taking default as 8168, leading to HASH join between the tables..leading to FULL TABLE access.

I can use hints to use indexes but planning to avoid it as of now. Currently the time shown in explain plan is not accurate

Thanks,
BThanks Tubby,
While searching I had found out that we can use CARDINALITY hint to set statistics for TABLE funtion.
But I preferred not to say, as it is currently undocumented hint. I now think I should have mentioned it while posting for the first time
http://www.oracle-developer.net/display.php?id=427
If we go across the document, it has mentioned in total 3 hints to set statistics :
1) CARDINALITY (Undocumented)
2) OPT_ESTIMATE ( Undocumented )
3) DYNAMIC_SAMPLING ( Documented )
4) Extensible Optimiser
Tried it out with different hints and it is working as expected.
i.e. cardinality and opt_estimate are taking the default set value
But using dynamic_sampling hint provides the most correct estimate of the rows ( which is 2 in this particular case )
With CARDINALITY hint
SELECT
/*+ cardinality( e, 5) */*
FROM
TABLE
SELECT
CAST(TABLE_ESC_ATTACH(OBJ_ESC_ATTACH( 9999, 99991, 'file1.png', NULL, NULL, NULL),

Note
- dynamic sampling used for this statement (level=2)I will be testing the last option "Extensible Optimizer" and put my findings here .
I hope oracle in future releases, improve the statistics gathering for collections which can be used in DML and not just use the default block size.
By the way, are you aware why it uses the default block size ? Is it because it is the smallest granular unit which oracle provides ?

How to use database control to execute sql queries which change at run time
Hi all,
I need to execute sql queries using database controls , where the sql changes
at run time
based on some condition. For eg. based on the condition , I can add some where
condition.
Eg. sql = select id,name from emp where id = ?.
based on some condition , I can add the following condition .
and location = ?.
Have anybody had this kind of situation.
thanks,
sathishFrom the perspective of the database control, you've got two options:
1) use the sql: keyword to do parameter substitution. Your observation
about {foo} style sbustitution is correct -- this is like using a
PreparedStatement. To do substitution into the rest of the SQL
statement, you can use the {sql: foo} substitution syntax which was
undocumented in GA but is documented in SP2. Then, you can build up
the filter clause String yourself in a JPF / JWS / etc and pass it into
the DB control.
For example:
* @jc:sql statement="select * from product {sql: filter}"
public Product[] getProducts(String filter) throws SQLException;
This will substitute the String filter directly into the statement that
is executed. The filter string could be null, "", "WHERE ID=12345", etc.
2) you can use the DatabaseFilter object to build up a set of custom
sorts and filters and pass that object into the DB control method.
There have been other posts here about doing this, look for the subject
"DatabaseFilter example".
Hope that helps...

Hi Maruthi,
The parameter substituion , I guess is used like setting the values for
prepared
statements.
What I'm trying to do , is change the sql at run time based on some condition.
For example ,
consider the following query :
select col1,col2 from table t where t.col3 > 1
At run time , based on some condition , I need to add one more and condition.
i.e. select col1,col2 from table t where t.col3 > 1 and t.col4 < 10.
This MAY not address your issue but if you are trying to add "optional" parameters
you may try including ALL the possible parameters in the SQL but send in null
for those params that you don't want to filter on in any particular case. Then,
if you word your query
as follows:
select col1, col2 from table t where t.col3 > 1 and (t.col4 = {col4param} or
{col4param} is null) and (t.col5 = {col5param} or {col5param} is null) ...
you will get "dynamic" filters. In other words, col4 and col5 will only be
filtered if you send in non-null parameters for those arguments.
I have not tried this in a WL Workshop database control but I've used
this strategy dozens of times in stored procedures or jdbc prepared statements.
Good luck,

[4.0] Production SQL Developer hangs when attempting to expand Java in the Connection Navigator
Folks,
I'm running production SQL Developer on Oracle Linux 5.8 and whenever I click the Java link in the Connections Navigator with a SYS AS SYSDBA connection SQL Developer hangs.
Oracle Enterprise Edition 11.2.0.1.0
SQLDeveloper 4.0.0.13.80
Oracle Linux 6
JDK Version 1.7.0_45
Doing the same thing with user SCOTT (no SYSDBA) works fine (although there are not any Java objects).
Thanks,
RichThis has been logged as a bug.
The bad plan/performance has been logged as a bug. SQL Developer didn't hang for me - I was able to cancel the query using the Task Progress panel. -

A SQL tuning issue-sql runs much slower in test than in production?
Hi Buddies,
I am working on a sql tuning issue. A sql runs much slower in test than in production.
I compared the two explain plans in test and production
seems in test, CBO refuses to use index SUBLEDGER_ENTRY_I2.
we rebuile it and re-gether that index statistcs. run, still slow..
I compared the init.ora parameters like hash_area_size, sort_area_size in test, they are same as production.
I wonder if any expert friend can show some light.
in production,

Thanks a lot in advance
JerryHi
Basically there are two kinds of tables
- fact
- lookup
The number of records in a lookup table is usually small.
The number of records in a fact table is usually huge.
However, in test systems the number of records in a fact table is often also small.
This results in different execution plans.
I notice again you don't post version and platform info, and you didn't make sure your explain is properly idented
Please read the FAQ to make sure it is properly idented.
Also using the word 'buddies' is as far as I am concerned nearing disrespect and rudeness.

Need a PL/SQL debugger support NCHAR type
Hello,
I'm looking for a PL/SQL debugger which supports NCHAR type of Oracle9i. I need it to watch variables of unicode data type (AL16UTF16).
Or, if you could share with me how you debug your stored procedures which involve unicode data types.
Thanks.
YanliThanks for the reply, Barry.
I use PL/SQL Developer for sql debugging. Unfortunately, it won't display a variable of NCHAR type, the watch window simply shows blank. I also find a freeware called Tora which supports unicode input/output, however, to debug stored procedure one needs to compile the procedure using its compiler first, and it just hangs all the time.
If you know some debugger which work good with NCHAR type, please let me know.

SQL DEVELOPER 1.5.3: Export Data options for using SQL to write SQL?
I write a lot of SQL that generates SQL. In a competitor's product, I can export query results (Export > Save As > Tab Delimited) to the clipboard, paste the generated SQL into a new window, then execute the generated SQL.
In SQL Developer, using Export Data > Text to the clipboard, it's delimiting each row with double-quotes. Is there any way to turn this behavior off to achieve what I want? Or should I be choosing a different export format?
For now, I can do a search/replace to eliminate the double-quotes,
Thanks.
DanaDana,
I probably haven't done this with generating thousands of SQL lines, but I have certainly used the Ctrl-A, Ctrl-C (or Ctrl-Shift-C to get headers) to copy thousands of records of result data. Note that the Ctrl-A forces a fetch of all remaining records that have not yet been fetched, which may add to the time taken by the process - for example, running the query fetches the first 50 records and then Ctrl-A will fetch the remaining records as well as selecting them all, however long that takes. Also, there is a noticeable delay with the Ctrl-C for thousands of records - only rough counting but I was seeing a UI freeze for ~ 4 seconds when copying 10000 records from a query with around 30 columns in it (pasting the clipboard into a file produced a file just under 4MB).
