We're using hsqdb-2.2.9 in dao tests. The hsqldb was made compatible with oracle (in production) by setting SET DATABASE SQL SYNTAX ORA TRUE; and we use ibatis sql map.
It gets failed when the sql contains table alias, something like select a.name, b.code form t_a a, t_b b where a.id = b.a_id , which reports unexpected token a. We tried adding 'as' between table and table alias, it doesn't work either. Do I miss something?
Yes, HSQLDB supports table aliases.
If you use the exact query you reported, you would get:
unexpected token: T_A
If you correct the query as commented by a_horse_with_no_name it should work. If one of the tables does not exist, you would get:
user lacks privilege or object not found: T_A
BTW, try using the latest 2.3.0 snapshot jar for better Oracle compatibility tests. You can find it from the support page of the website.
uh.... I think I‘ve found the issue........of my own. It suddenly occur to me that I use ’do‘ (table name is t_delivery_order) as the table alias which happens to be a keyword in hsqldb(or in sql). Just replace 'do’ with 'd', its fixed. Thank u all

I am using MyBatis 3 to create a request (seen below) however, I am getting:
ORA-00942: table or view does not exist
where SYNONYM_A is a public Synonym for a table in another database...
I know the example doesn't really help, but the real question is, "Is there a special syntax for synonyms in Batis?" Has anyone done this, or failed, and can tell me, so I don't spend a great deal of effort, if it is not valid in Batis?
#Select("select * from SYNONYM_A where some_det_key in (SELECT DATA_KEY FROM SOME_PARENT_TABLE WHERE PARENT_KEY = 1234 AND (ATTACH_PARENT_FLG = 1 or ATTACH_PARENT_FLG is null) AND DATA_SRC = 'LV_SOME_DET') ORDER BY pair
Provide the select grant FROM the PARENT schema to the current schema once again for the table of which SYNONYM_A is a synonym of.
And is SYNONYM_A a synonym for a Table or a synonym of another SYNONYM in the PARENT schema?
In case it is, u need to provide grant from the ultimate base schema where the actual table is located once again 'WITH GRANT OPTION'
A public synonym does not mean that grants are not required from the schema in which the parent table lies(if the synonym and the table lies in two different schemas, that is). You need to clarify your concept of public synonyms :) .
But thats not the point here.
just do:
SELECT * SOME_TABLE"#"CONNECTION_TO_ANOTHER_DATABASE;
If this gives you ORA-XXXX: Table or view doesnot exist, then this is the cause.
There are two possibilities:
1.CONNECTION_TO_ANOTHER_DATABASE has got corrupted/doesnot exist.
You can check this by doing queries like :
Select sysdate from duals#CONNECTION_TO_ANOTHER_DATABASE;
Select * from user_objects#CONNECTION_TO_ANOTHER_DATABASE;
If this too gives you the same error then that's it, your CONNECTION_TO_ANOTHER_DATABASE is gone.
If this does not give any error and gives some valid o/p then:
2.Probably the "SOME_TABLE" at the remote database does not exist!
The answer is....
I was connected to the wrong database instance!! I had built extended AbstractRoutingDataSource, and was pulling the server name for the datasource from a primary database. I discovered that another individual had populated this table incorrectly, and pointed me to a database where the synonym did not exist.
Thank you for your responses, and your time.
I have a strange case here. I created a View in AS/400. I need to have view not join logical because I need to do a UNION ALL. The view is created and I went to IFS and granted permissions ALL. But when I open Crystal Reports, make the connection to iSeries, and go to that library of the View, it is not showing, so I cannot use.
Is there anything else I need to do?
I just tried something else. this is the view:
CREATE VIEW MKLIB/BEMPLOCM AS
((SELECT LMRIDC, LMCOM#, LMWHS#, LMLOC1, LMLOC2, LMLOC3, LMLTPC, LMLCT1
FROM
((SELECT LMRIDC, LMCOM#, LMWHS#, LMLOC1, LMLOC2, LMLOC3, LMLTPC, LMLCT1
FROM ASTDTA/ICLOCMLM WHERE LMLTPC IN ('PCK', 'PAL', 'RAK')) t1
EXCEPTION JOIN
(SELECT * FROM ASTDTA/ICBALMIE) t2
ON LMLOC1=IELOC1 AND LMLOC2=IELOC2 AND LMLOC3=IELOC3 )
EXCEPTION JOIN
(SELECT * FROM ASTDTA/ICBLDTIR) t3
ON LMLOC1=IRLOC1 AND LMLOC2=IRLOC2 AND LMLOC3=IRLOC3 ))
Now in Crystal reports there is also COMMAND to use to get your data, there you can make the same query but although I want it on the AS/400 for time consideration, the union is needed otherwise i have to run the queries via CL all day. SO I took the above code from the SELECT point, and got this error:
failed to retrieve data from the database. Details: HY000 IBM ISeries
ACCESS ODBC DRIVER (DB2 UDB) sql 5016 - Qualified object name ICLOCMLM
not valid. Vendor code 5016.
Not sure what that means.
Use the GRANT statement to control SQL privileges.
If the view is over regular files you may also have to use the commands GRTOBJAUT, EDTOBJAUT and RVKOBJAUT to modify authorization on those objects.
"It does not list it in the library when I see the tables and views in crystal."
Are you sure that the view is actually in the library you think?
What may have happened is that it may have been created in another library. Try checking in QGPL library, or if you have a library that matches your user profile name, check there.
If the question is 'Why do I get Qualified object name ICLOCMLM not valid.' the answer is probably that you are using *SQL naming and the statement you are running is using *SYSTEM naming. Try changing FROM ASTDTA/ICLOCMLM to FROM ASTDTA.ICLOCMLM and see if the 5016 error goes away.
I have the linked server set up in SQL Server 2008. But I could not run any query against the linked server.
I tried to run this simple command but it's not working
SELECT * FROM MYSERVER..ALANH.TEMP_UPDATE1
This is the error I got when I run the above command.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER" reported an error. The provider did not give any information about the error.
Msg 7312, Level 16, State 1, Line 1
Invalid use of schema or catalog for OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER". A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog or schema.
Could anyone help me to connect to the OracleLinkedServer? Thanks very much.
you can be that way too:
**SELECT * FROM OPENQUERY(MYSERVER, 'SELECT * FROM ALANH.TEMP_UPDATE1')**
You can write the query like this:
select * FROM [MYSERVER]..[ALANH].[TEMP_UPDATE1]
Important: In this case, the fully qualified table name must be written in upper case.
You might try the fix from this article.
Also, this could be a problem with naming. From an MS KB article
If you receive these error messages, a table may be missing in the
Oracle schema or you may not have permissions on that table. Verify
that the schema name has been typed by using uppercase. The
alphabetical case of the table and of the columns should be as
specified in the Oracle system tables.
On the Oracle side, a table or a column that is created without double
quotation marks is stored in uppercase. If the table or the column is
enclosed in double quotation marks, the table or the column is stored
as is.
First make sure the tnsping utility works from client server, then use the below string in linked server database source setup
host[:port]/service_name
Check this link for more details :
http://www.oracledistilled.com/oracle-database/oracle-net/using-easy-connect-ezconnect-naming-method-to-connect-to-oracle-databases/
Try something like this:
SELECT * FROM ALL_TABLES#"SOME.SERVER.NAME";
In this case I'm selecting ALL_TABLES from a linked server called SOME.SERVER.NAME.
Richard's post above was critical.
I am using v12 ODP.NET odbc drivers and had to ensure that "Zero Level Only" was NOT checked and that the names supplied for table and schema were the correct case. All of the schemas and tables I access are uppercase only.
Use the query below to determine what the correct table name is, though you will have to supply the schema name in the correct case for the query to work. Try all uppercase, try all lowercase, try mixed case, or better yet get the actual name from the dba (I've heard that only table/schema names that are "" quoted will be allowed mixed case, otherwise in oracle it's all uppercase.)

yesterday I've been trying to make this code work inspite the fact it's just working fine with nhibernate and SQL server but when it come to oracle it generate wrong sql
UnitOfWork.Current.CreateCriteria<Bill>().Add(Restrictions.IsEmpty("ReqId"))
.SetMaxResults(BatchSize).SetLockMode(LockMode.Upgrade).List<Bill>();
the generated SQL will something like
Select * from
(Select bill_0.id,bill_0.BillNo ...... from Bill bill_0 where bill_0.reqId is Not null )
where ROWNUM < 10 for UPDATE of bill_0.ID
so i wont run because the allies bill_o is defined inside the inner sql statement so who got the solution ?
the correct sql would be something like this which i tried and worked on oracle db
Select bill_0.id,bill_0.BillNo ...... from Bill bill_0
where bill_0.reqId is Not null and ROWNUM < 10 for UPDATE of bill_0.ID
Since, as you say, NHibernate is generating invalid Oracle SQL, I suggest you file a bug with the NHibernate people. The SQL would work if the in-line view had been assigned an alias of "bill_0", or if the FOR UPDATE clause didn't use a table alias ("for UPDATE of ID"). Whether you can modify your NHibernate calls to make either of these happen I'm afraid I have no idea.
Here is my problem, I wants to create a baseline on our development Dateabase (Oracle 10g), and check into our svn for version control, and after this we will use liquibase to help us manage the incremental database changes.
My problem is how should I create baseline of Oracle 10g? the database now consists of 500+ tables, with large amount of configuration data, and I wants my db baseline to base on a set SQL scripts to check into subversion, rather then check in Oracle dump..
I have try use liquibase generateChangeLog, but it have some performance problem.. can anyone can recommends me any tools that will help me
1. Scan any Oracle Schema
2. Generate a set of SQL Scripts (With Table structures, and Data)..
Thanks in advance
James!
Something like
SELECT DBMS_METADATA.GET_DDL('TABLE',table_name) FROM USER_TABLES;
is a good start. You can tweak it with PL/SQL and UTL_FILE to get it to write each table to a different file. You will probably need to do sequences too (though versioning them is fairly pointless), and maybe triggers/procedures/functions/packages etc.
Don't forget grants.
Have you tried Oracle's free SQLDeveloper tool? It gives you the possibility of exporting DDL and data.
EXPDP with CONTENT=METADATA_ONLY option, then IMPDP with SQLFILE=your_script.sql ?
Nicolas.
More general solution would be to dump DDL sql for selected list of tables, but additionally also other types of objects. This could be done by using all_objects and all_users views.
Example that worked for me:
select dbms_metadata.GET_DDL(u.object_type,u.object_name, u.owner)
from all_objects u
where 1=1
-- filter only selected object types
and u.object_type in ('TABLE', 'INDEX', 'FUNCTION', 'PROCEDURE', 'VIEW',
'TYPE', 'TRIGGER', 'SEQUENCE')
-- don't want system objects, generated, temp, invalid etc.
and u.object_name not like 'SYS_%'
and temporary!='Y'
and generated!='Y'
and status!='INVALID'
and u.object_name not like 'TMP_%'
and u.object_name not like '%$%'
-- if you want to filter only changed from some date/timestamp:
-- and u.last_ddl_time > '2014-04-02'
-- filter by owner
and owner in (
select username from dba_USERS where DEFAULT_TABLESPACE not like 'SYS%'
and username not in ('ORACLE_OCM')
and username not like '%$%'
)
;
I wrote a python script that refreshes db schema in incremental mode based on similar sql:
runs sql with last_ddl_time>=max(last_ddl_time from last refresh)
at the end stores last_ddl_time somewhere in filesystem for next refresh
