How get all table name from database

hi master
sir
how get all table name from database

The big question is 'why'.
Selecting from view 'dba_tables' will indeed give the list of all tables in the database, but that includes the dictionary tables and the internal tables, and many others that are probably not of interet to a person who needs to ask this question. Besides, the dba_tables view requires access to a DBA account.
There are several other views: "user_tables" will list all the tables in this user's schema; and "all_tables" will list all the tables this user can access in some way.
The above do not, of course, include any information about synonyms, sequences, views, indexes and so on.
The correct answer and the meaningful answer may be two different things.

EF 5 Model First Approach- How to avoid Table names from pluralized

I'm using Entity Framewrok 5.0 Model First approach using Visual Studio 2012 express. The generated database tables are pluralized. How do I avoid this? Please advice. I'm using Model First approach (Designed the entities in the EF designer and generated
the Database.) . Please note that following technic does not apply to this scenario as it applies to code - first approach.
using System.Data.Entity.ModelConfiguration.Conventions;
protected override void OnModelCreating(ModelBuilder modelBuilder)
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

Hi Arasheed,
Welcome to the MSDN forum.
I tested your problem. It seems a default setting that Table names are pluralized. If you want to avoid pluralizing, you can do it manually:
Right click the empty area and select “Generate Database from Model…”.
Choose the correct connection and click “Next”.
You will see the generated DDL. Please copy all the content, then click “Cancel”.
Click “Data” on the Visual Studio bar and select “Tansact-SQL Editor”. Then click “New Query Connection…”.
Connect to the right server.
Paste the DDL we copied before.
Modify the table creation lines. Note: do not forget to change the corresponding name in constraints.
Right click the empty area and click “Execute SQL”.
In addition, you can submit your feature requests here to improve Entity Framework:

Get the table names from a specified schema name

Can't any one can hlep me how to use OCIDescribeAny() to retrive the list of table names for a given schema name?
I have problem when I connect to the database using syste as usr id. I can't ge the table name form the SCOTT schema.

If I understand you correctly, I don't think OCIDescribeAny() is the way to go.
You can get a list of tables owned by a particular schema by using the following SQL:-
SELECT TABLE_NAME FROM DBA_TABLES WHERE OWNER = 'SCOTT'
Just change the where clause to your needs.

Getting table name from a query

Hi, I'm trying to get the table name from my sql query
My code is as follows;
ResultSetMetaData metadata = rs.getMetaData();
for (int i = 1; i < metadata.getColumnCount(); i++)
System.out.println(metadata.getTableName(i));
I just get a blank output. Yet my sql query executes and I can pull down the records, and grab the column names from the result sets.
Any ideas on how I can get the table name for the columns. The reason being is on one of my querys I'm using join statements and i need to retrieve the table name for the column i'm displaying, as some tables have similar column names.
Thanks in advance.

Hi,
What db are you using?
I also get a blank output with ResultSetMetaData.getTableName because Oracle doesn't implement this method.
Why do you not know the table name anyway?

Table name from field

Dear Sapers,
How to find table name from field name to write functional spec.Pl elaborate it for normal & zdevelopment.Points will be rewarded for useful answer.
Thanks in advance.

Hi Uday,
Just for the sake of help this reply......
You can find the name of tables by using F1 button keeping cursor on the respective field that you want to bring in development. From there you have to move to Technical details through technical details button.
If that field or values are getting saved into some structure then you have to search the right database tables. According to your module many database tables are there (that you can search from sdn.sap.com directly). That totally depends on your report/development that you want to bring in......
In any development deciding the right table for start up ( I mean to say tables that will give you input fields in your FS) is critical, latter you have to search linking tables and have to give logic about how to pass values from what to what field and what to what table..... In this case Transaction code SE11 and SE16 are useful......
This all is slightly confusing and tedious too...... Closely work with you ABAPer to get into many things and have successful development....
Have nice development....
Cheers!

Get all html files from a url

Hi I am trying to do a website copyer and i don't know how get all the html from a url.
By example:
I want get all files html from http://forum.java.com/
aAnybody has an idea of how to do this?
Thanks

Not easy. First, you'll have to look at networking programming - how to make URL connections etc.. Then, you'll have to look at HTML parsers - how to extract links, images, etc. from an HTML page. Also, you'll have to know how to do file I/O in order to save the HTML files obtained.
I don't know of any Java-based web site copier open source projects that you can refer to, but you can take a look at the source code for projects such as HttpUnit and HtmlUnit. They contain code that'll help you with your web site copier.
Good luck!

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

Getting table column header names from database

Hi,
We are trying to get table headers from database. So when we query the database it returns multiple rows at the same time. How can we display specific table column headers from the returned result set at respective places.
We tried using record selection expert but that only works for one selection and not for others.
How can we do this?

Thank you Josh and Abhilash for helping us.
We are using PostgreSql.
"command_headers" has query which looks like following-
SELECT id, header FROM labels
WHERE id='header.header_1'
OR id='header.header_2'
OR id='header.header_3'
ORDER BY id;
which will return following result set-
id                              header
header.header_1        Header1
header.header_2        Header2
header.header_3        Header3
Our Table structure is something like this-
Page Header: Header1                        | Header2                       | Header3
Details:           {command_data.value1} | {command_data.value2} | {command_data.value3}
command_data is another command which generates data for the table.
All values in details section coming from command_data is in format string.
We don't need to apply grouping or sub totals. This is a simple table, showing string values for all columns.
Preview:
Header1     |     Header2     |     Header3
car              |     yello           |     abc
bike            |     black          |     xyz
plane          |     white           |     pqr
Currently, all headers are static labels. How do we use "command_headers" to display all table Headers dynamically? Can we achieve this format using cross tab?

How to find out all table names which has a particular data

Hi,
How could i get all the table names from a database(for a schema) which has data 'KST6490' in one of the fileds in the table.There are many tables with this
data. Data type is Varchar2. Thanks.

One approach would be to create a procedure which retrieves the name of all tables in the schema using the user_tables view. Then use the user_tab_columns view to get all the column names and types. If the type is varchar2, then dynamically create a sql statement which runs a query on that column using the value which you are looking for. You would need two cursor loops for this approach: one for tables and one for columns. This approach requires good PL/SQL programming skills.
Alternately, many query tools, such as Golden, provide a search capability on query results. Just do a select * from the table and search on the results. This would need to be done table by table and the results would have to fit in the memory available to the tool.
Alternately, you can write table contents to a text file on the a server and then search the text file using operating system tools such as grep. This would require good OS scripting skills.

How to get the table name of a field in a result set

hi!
i have a simple sql query as
select tbl_customerRegistration.*, tbl_customerAddress.address from tbl_customerRegistration, tbl_customerAddress where tbl_customerAddress.customer_id = tbl_customerRegistration.customer_ID
this query executes well and gets data from the database when i get ResultsetMetaData from my result set (having result of above query) i am able to get the field name as
ResultSetMetaData rsmd = rs.getMetaData();//rs is result set
String columnName = rsmd.getColumnName(1);
here i get columnName = "Customer_id"
but when i try to get the tabel name from meta data as
String tableName = rsmd.getTableName(1); i get empty string in table name....
i want to get the table name of the respective field here as it is very important to my logic.....
how can i do that.....
please help me in that regard as it is very urgent
thanks in advance

http://forum.java.sun.com/thread.jspa?threadID=610200&tstart=0

So far as I'm aware, you can't get metadata information about the underlying tables in a query from Oracle and/or the Oracle drivers. I suspect, in fact, that the driver would have to have its own SQL parser to get this sort of information.
I'm curious though-- how do you have application logic that depends on the name of the source table but not know in the application what table is involved? Could you do something "cheesy" like
SELECT 'tbl_customerRegistration' AS tbl1_name,
tbl_customerRegistration.*
