How to don't write schema name in oracle sql query?

I have Workspace/Schema EDUCATION in Oracle XE.
In my Java code I want execute queries like this: SELECT * FROM Table instead of SELECT * FROM EDUCATION.Table.
When I write query without EDUCATION I have error: table or view does not exist.
I tried to set the default schema to % (screenshot), but it did not help.
How to avoid writing Workspace/Schema name?

If I understand correctly, you want to access tables in other schemas without using the schema name.
One simple way to do this uses synonyms. In the schema you are connect to:
create synonym table for education.table;
Then you can use table where you would use education.table.

Get All tables allowed to user with jdbc

I'm connecting to a database using jdbc, getting list of all schemas and tables from database (I assume that some databases may return at this point only tables which current user can query, but some of databases return full list of tables) and when user try to query some tables he get "insufficient privileges" error.
Is there a way to get only tables, user can query using only jdbc capabilities? Without writing special query to database.
Now I'm looking at
DatabaseMetaData dbMeta = connection.getMetaData()
dbMeta.getTablePrivileges(null, null, null);
But from result of this query it's not so clear which exactly tables can user query.
Currently I'm working with SAP HANA database, but in general it may be any database, so I'm looking for some common approach.

Please look at
http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getTablePrivileges%28java.lang.String,%20java.lang.String,%20java.lang.String%29
You have to get the each row from the ResultSet and query of column name TABLE_NAME which contains the table name and PRIVILEGE which contains the access of each table.

Selecting from FileMaker table via JDBC when the table name contains spaces

I am using JDBC to get data out of a file maker server v12.
For some unknown reason filemaker allows you to have spaces in your table names. I am unable to select these tables because I just get a syntax error.
I have written an application in java to get the data out. Does anyone have any idea how i can select the data from a table with a space in it?
EDIT (from OP's comments):
This is the Java part:
String selectSQL = "SELECT "+this.getImportableColumnsString()+" FROM "+this.getTableName();
PreparedStatement preparedStatement = this.connection.prepareStatement(selectSQL);
ResultSet rs = preparedStatement.executeQuery();

As mentioned in a comment to the question, if the FileMaker table name contains spaces then it must be enclosed in double-quotes in the SQL statement, e.g.,
String selectSQL = "SELECT * FROM \"table name\"";

My first thought is that you could put the table name within ' characters like: SELECT * FROM 'my table'. Does this not work?
Otherwise I suggest you contact the Filemaker Server support on this page:
http://help.filemaker.com/app/ask
It is likely that they have had this question before and knows how to build the query.
//Flipbed

I'm pretty sure in the docs for OCDB and JDBC support FileMaker says that tables may have to comply to naming conventions that are stricter than what FileMaker allows. It is easy to change table names in FileMaker if you have admin access to the database you are sourcing why not just replace the spaces in the table names with underscores.

Hibernate multiple native SQL statements

I want to run a native SQL from a file using Hibernate. The SQL can contain several statements creating the database structure (i.e. tables, constraints but no insert/update/delete statements).
Example, very simple query is below (which contains the following two SQL statements)
CREATE DATABASE test;
CREATE TABLE test.testtbl( id int(5));
I am using MySQL db, and when I run the above query I am gettng syntax error returned. When I run them one by one, its ok.
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
You have an error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near
'CREATE TABLE test.testtbl( id int(5))' at line 1
The code to run the query is below (above statement is assigned to 'sql' variable):
session = sf.openSession();
session.beginTransaction();
Query qry = session.createSQLQuery(sql);
qry.executeUpdate();
session.getTransaction().commit();
Any help would be appreciated.

As others have explained
You must run these queries one by one.
The hibernate code gets translated into running one update statement on JDBC.
But you provided two update statements.
In addition,
I personally prefer to have the code that creates tables outside of the Java application, in some DB scripts.

The parameters of the method createSQLQuery is t-sql code;
t-sql code to ensure that in the mysql interface analyzer correctly.
You can try changed the sql :'CREATE TABLE testtbl(id int(5));'
by the way you can use JDBC Connection api (Don't recommend to do so)
Such as:
java.sql.Connection conn=session.connection();

Db2 connection problem with java

I am having problem with DB2. I just installed the db2 as a db2admin and with a password. When i try to connect to database it is success full and while running any simple select query it give me following error:-
DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2ADMIN.LOGIN, DRIVER=3.57.82
I have a database named onp and a table in it called 'login' in which there is one table called 'login' with two fields username and password.
Query that i am running
Select * from login; gives me error
DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2ADMIN.LOGIN, DRIVER=3.57.82
Select * from system.login; gives me error:- (//system is schema name)
DB2 SQL Error: SQLCODE=-551, SQLSTATE=42501, SQLERRMC=DB2ADMIN;SELECT;SYSTEM.LOGIN, DRIVER=3.57.82
I have tried all the resources on the net and exhausted completely. Please help me

I don't know a lot about DB2, but looking up the error codes...
The first error is because you didn't specify a schema, so it couldn't find the login table.
SQLCODE -204 Object not defined to DB2
DB2 apparently requires you to specify the schema name or it looks in the schema with the same name as your login user.
You must use SET SCHEMA or fully qualify the table name.
The second error is because you don't have the privileges to perform that select:
SQLCODE -551, Error: DOES NOT HAVE
THE PRIVILEGE TO PERFORM OPERATION ON
OBJECT
I'm not sure why the db2admin user wouldn't be able to select from this table...
Resources:
List of DB2 SQLCODEs

SQL CODE 551 occurred because the connecting user does not have privileges to perform operations.
Go to Control Center - Go to User Group and Object and select DB2ADMIN(assume this user is the one use to connect to DB2)
Check all the check box as the following
Grant Schema access to the user
Grant Tables access to the user

I had the same problem and i resolved it by adding Schema in my entity :
#Entity
#Table(name="MyTable", schema="MySchemaName")
public class MyClass implements Serializable {
...
}

You can also resolve the issue as:
Just give the proper authority to the user by which you are connection to DB2.
