Export creates empty .sql file

When I right-click a table name and click through the export process, the resulting file is named correctly in the correct location but is 0KB. Any thoughts?

Please do not reply. Found suggested procedure in thread and works as described. Thanks anyway.

Unload Creates a .sql file in addition to an .xls file

Hi All, I've recently downloaded version 3.0.02 which I use to create queries for database interrogation. I tend to export to Excel regularly and I'm finding that every time I unload an .xls file a .sql file is created in tandem.
I have no use for this and have tried many different settings in the preferences area to stop it being created but to no avail - in addition the unload seems to take as long as the original query as if the query is being rerun - can somebody tell me what I'm doing wrong? Many Thanks, Steve.

Is the additional file you are seeing the Generated-<date-time>.sql file?
This file is generated when using a Save As type that can potentially create multiple sql files. It should not be created when generating Save As Single File. When we create a single sql file during the export, a generated control file is not needed and we should not create it... even if the Save As type is separate files, type files or separate directories. However, I can see that we are generating that control file when the Save As type is separate files, type files or separate directories cases and we created just 1 export file.
Selecting the SaveAs type as single file should get you around the problem.

Export Schema to .SQL file

This has been discussed on the forums before, in thread
Re: How to export an exisitng schema to DDL script?
but that seems to deal with previous versions of Oracle, before the web-only interface. How would this be accomplished in Oracle 10g? I need to export the DDL(and data if possible in the same statement) of one entire schema to a .sql file to be run on an install.

In addition to using DBMS_METADATA, you can try using SQL Developer (same options tools -> Export DDL). This would work for 10g just as well as pre-10g releases.
Only issue with this approach as I have seen it with SQL developer, is it does not put the object creation in proper order (It created a script where index was created before creating a table which of course would fail). This means you will have to edit the script any way for it to work.
Another issue with SQL Developer script is that (if you also want include data in the .sql file) it writes individual insert statements for each row. This again poses a problem if tables and indexes are not created in order before inserting data (especially creating appropriate FK constraints). Also this is going to be very slow option (from performance point if you have tables with millions of rows).
For migrating data from one instance to another I would use export/import or 10g Data pump.
10g DB control or Grid Control do not give you a simple point and click to achieve exporting of schema.
The way I see it is to use some case tools like Oracle Designer or ErWin.
Hope it helps.

Help with creating a sql file that will capture any database table changes.

We are in the process of creating DROP/Create tables, and using exp/imp data into the tables (the data is in flat files).
Our client is bit curious to work with. They do the alterations to their database (change the layout, change the datatype, drops tables) without our knowing. This has created a hell lot of issues with us.
Is there a way that we can create a sql script which can capture any table changes on the database, so that when the client trys to execute imp batch file, the sql file should first check to see if any changes are made. If made, then it should stop execution and give an error message.
Any help/suggestions would be highly appreciable.
Thanks,

Just to clarify...
1. DDL commands are like CREATE, DROP, ALTER. (These are different than DML commands - INSERT, UPDATE, DELETE).
2. The DDL trigger is created at the database level, not on each table. You only need one DDL trigger.
3. You can choose the DDL commands for which you want the trigger to fire (probably, you'll want CREATE, DROP, ALTER, at a minimum).
4. The DDL trigger only fires when one of these DDL commands is run.
Whether you have 50 tables or 50,000 tables is not significant to performance in this context.
What's signficant is how often you'll be executing the DDL commands on which the trigger is set to fire and whether the DDL commands execute in acceptable time with the trigger in place.

How to create empty text file on target system for empty source text file

Hi All,
I have an issue in handling empty file in the Text (FCC) to Text (FCC) file scenario. Interface picks text file and delivers on target system as text file. I have used FCC in both sender and receiver CCs.
Interface is working fine if the source file is not empty. If the source text file is empty (zero Bytes), interface has to delivery an empty text file on target system. I have setup empty file handling options correctly on both CCs.
But when I tried with an empty file I am getting the error message 'Parsing an empty source. Root element expected!'.
Could you please suggest me what I need to do to create an empty text file on target system from empty source text file?
Thanks in Advance....
Regards
Sreeni

the problem is that when there is an empty file there is no XML for parsing available. Hence in case you are using a mapping it will fail.
What ideally you should do is to have a module that will check if the file is empty and if so write out an XML as you want with no values in the content/fields.
Or the next choice would be to have a java mapping to handle this requirement. I guess that on an empty file the java mapping will go to an exception which you can handle to write out your logic/processing

Export definitions to sql file

Hi,
One quick question. What tool should I use to export table definitions, procedures, functions to a sql file?
Is there a freeware to do this ?
Thanks,
pesq

You can use dbms_metadata.get_ddl package to get the database objects definations. So, you may need to spool the output in .sql file.
I'm not sure but try out TOAD trail version for this.

AddressBook created empty backup file

10.4.7 with all the updates. I tried to backup AddressBook as its been a couple months since the last backup. I get the file, but it is a directory with only one file named xxx and has size of zero. Removed the AddressBook preferences, ran Preferential Treatment, Rebuilt Permissions and no change. Everything else in AddressBook works fine. ktrace of AddressBook shows lots of file activity but no real attempts to write to the backup file, just the creation of the directory and the xxx file.
Switching to a test user account, AddressBook generates a backup file with data in it.
macbook pro

I wish I had a good answer for that. The basic approach I used was to run ktrace to see if I could find the cause. Thats what left the xxx file in the directory. It didn't help. Then I found 2 prefereneces for Address Book. The obvious one and one what another few characters at the end. I removed both and let it rebuild. Only the obvious one got rebuilt. That didn't help. Thats when I noticed that the contents of the backup file only consisted of an empty xxx file. Removing the xxx file from the address book directory then made everything work. Obviously the xxx file was not the original cause. However, it also kept address book from creating a backup. Perhaps there was something in one of the 2 preference files that originally caused the problem. I can't tell at this point.

'mail event' creates empty calendar file

I can send ical events by adding invitees, but when I use the control-click 'mail event' method, the ics that gets attached to the mail is empty (when you try to add it to ical it errors with 'This calendar file is empty. No new new events have been added to your ical calendars'. This has worked previously, and works on other macs, no problem.
Any ideas would be much appreciated.

I'm having this problem too, and I have all the latest updates installed. Not sure where to go next.
Any ideas?
Thank you.

Is it possible to open a new Worksheet without creating a new *.sql file

Hello Community,
Declaimer: It may be a trivial question. I just willing to make SQL Developer my default day to day tool.
I is possible to open a new Worksheet without creating a new *.sql file. Like in an MS Word. If I just need some space to write something and than destroy the file without saying. I can quickly click < ctrl + N > and get the space.
In SQL Developer to get a new "space"/work sheet i
-a- < ctrl + N >
-b- choose "SQL File"
-c- confirm default location
-d- choose the connection to be used (right top conner)
This process is way to long for getting a new sheet to put write an SQL.
Can you suggest a better way to get a workspace with current connection assigned in no time (like in MS Word)?
Please ;)
Yury

There is no need to create new .sql file.
I don't know why you need new SQL Worksheet when you can simply do the space by pressing Enter, but you can open a new one from Tools -> SQL Worksheet. There is also a toolbar button for this.

Create *.sql file

Hi I have a Database structure done, with all the constraints and the indexes and triggers and functions and stored procedure and the contents of the static tables.
I wanna create create a .sql file, so that when I execute this file, on another database I can find all the tables and triggers and contents of static tables...
I'm using oracle 9i btw, does anyone have any idea how this can be done?
thanks.

Assuming you are on Windows, just go into notepad or a text editor, write your script.
When you save it, make sure to save it as All Files (*.*) and not as a text file (.txt). Then just throw a .sql extension on the end when you save it.
Alternatively you could probably go through SQL*PLUS and edit the buffer. Save the buffer as a .sql and its the same thing.
Make sure to include / at the end of command "blocks" if you are going to run it as a script through SQL*PLUS.
Enjoy!

SSIS creates empty flat fie, how to avoid that?

I have a simple SSIS data export package - Data Flow task which takes data from db table and puts it in a flat file.
SQL Agent is used to run this SSIS data export package every 2 minutes.
Sometimes table is empty, does not have new rows that's why
1 - empty file is being created
2 - SQL Agent gave an error: The step did not generate any output. The return value was unknown. The process exit code was -1073741819. The step failed.,00:00:02,0,0,,,,0
I placed a "Execute SQL Task" step to count rows in the source table and
disable Data Flow task
if user::count==0 - this still creates an empty file.
Is there a proven workaround to use count variable and actually
disable Data Flow task and avoid creating empty flat file???
Are there any specific rules in setting up "result name" in "SQL Task" "result set" where you map Result Name and Variable Name?
Should it be column name, like "count" for select count(abc) as
count from TABLE
Thank you in advance!

Question about Precedence Constraint - should this work?
In control flow:
1st task
"Execute SQL Task" step to count rows in the source table
Next - Precedence Constraints - Expression - @[User::count]==0 (what should happen
with 2nd task if expression condition is met?)
2nd task: Data Flow which actually exports data from db and puts it into flat file.
In this scenario empty file is still being created...is there something wrong with my Precedence
Constraints - Expression - @[User::count]==0?
Brba,
Yes, there are 2 methods:
method1
Have the sql inside a execute sql task and obtain the rowcount into a variable. if the rowcount is greater than 0 then proceed to data flow task which will then execute sql
again and push data into flat file.
So you may set the precedence of the flow from Execute Sql task to Data flow task as an expression as :
@[User::Count]>0
i.e., only if its greater than zero, will the control even reach the DFT.
MEthod2
Similar method using @count variable. Have a data flow task followed by a file system task.
Inside the DFT, have the Rowcount transformation between the source and destination that would obtin rowcount into @count variable.
Now similar to above method, set precedence of the path (connnecting DFT and File System task) as expression such that @[User::Count] <=0 . So if rowcount IS zero, will reach FST - wherein you may program as DELETE FILE and select connection as flatfile
conenction manager itself.

Jay

Now i want some query to get the name of the file which is run.
In actual my problem is as
i have suppose 10 or more SQL files in some folder ( sql1.sql, sql2.sql, sql3.sql ....).

Oracle 9i export error after running catexp.sql file

After running catexp.sql file in oracle 9i 9.2.0.7.0 as system user,it gives the following error while logging
ORA-04020: deadlock detected while trying to lock object SYS.DBMS_STANDARD
please help me..............

"catexp.sql" is to be run by SYS AS SYSDBA.
You'd have to cleanup any extra objects that you created in the SYSTEM account.
Why did you think that you needed to run "catexp.sql" ? Are you exporting using 9i exp against a 10g database or against a 9i database ?

Manual backup of bookmark json file is empty, export of bookmark html file "self-deletes"

I'm now using Firefox 17.0.11esr in Win 7 at work and 26.0 in Win XP at home. I tried 24.2.0esr at work, but had to return to the earlier version, because of this problem below, which also happens with my home machine:
I cannot save, manually or automatically, a usable bookmarks json file for use as a backup. The files are always empty.
When I try to export a bookmarks html file, it begins to create and save it, but then "self-deletes" it before it's done.
Why is this a problem with 24.2.0esr and 26.0, but not 17.0.11esr? What can I do about it?
Thanks

You can try to create a new profile and keep both profiles open at the same time.<br />
You can do that by starting the second instance with the -no-remote command line switch (see further down).
Then you can do a copy and paste of the bookmarks in the Bookmarks Manager (Library) from the current profile to the Library of the new profile to create a new places.sqlite database file.<br />
If that works then you can copy this places.sqlite file to your current profile folder.<br />
You will lose the history, but it is possible to copy history items to a bookmarks folder in the new profile.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
You can also opt to keep using the new profile and transfer some files from the old profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem.
*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
See:
*http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows
Use the -no-remote command line switch to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.
