Retrieving Database Name in PL/SQL

I want to declare a variable whose value needs to be set to the database name. I don't want to pass it in as a parameter as it's an anonymous block in a unix script. Is there anyway other than assigning the variable "select * from global_name" within the executable section!?

Well, there's
SELECT SYS_CONTEXT ('USERENV', 'DB_NAME') FROM DUAL
/but I'm not sure you'll like that any better.
there isn't (to my knowledge) anything equivalent to teh SYSDATE function for database name.
Cheers, APC

Database name in MS SQL server 7/2000

Hi, Folks!!
I have a (basic) question regarding connecting up to an MS SQL server. I know the basic syntax of connecting to the server, however, I have not seen any examples on the java.sun.com site that show where you can insert the database name in the connection statements. I have search (some) of the discussions here but have not found anything anything conclusive.
Could someone point me in the right direction, at least?
TIA,
Signed: Frustrated!
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAUGH!!!

Okay,
I think I got it!
instead of using:
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection con = DriverManager.getConnection("jdbc:microsoft:sqlserver://<srvrName>:<portNumber>;DatabaseName=<dbName>", UID, PWD);I used the following:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:<srvrName>;DatabaseName=<dbName>", UID, PWD);I don't have any of the extra Microsoft drivers installed on my computer so I had to use what was available with Java and that is the JDBC-ODBC bridge. It was just a simple matter of adding ";DatabaseName=<dbName>" to what I already had. It makes sense now that I think about it. I hope somebody stumbles accross this message someday and avoids the grief I went through.

How to remove database name from SQL query

We have an MS SQL server with several databases that are of the same schema but have different data. We do this for testing different environments. We are using Crystal reports for the first time and we are having trouble changing the database location in the designer. If update the data source location to the same database server, but different database name, the data still comes from the original database used when creating the report. We look at the SQL query and it contains the database name and does not change when updating the data source. Therefore the data always comes from the database used when originally creating the report.
How can I remove the database name from the SQL query so the proper database is used when testing the report?

Hi C F
Please ensure you have followed the procedure mentioned below:
In Crystal Reports, there are two ways to set the location of the data source your report points to, depending on your connection type.
For ODBC and Native Connections:
1. On the 'Database' menu, click 'Set Datasource Location'.
2. In the 'Current Data Source' section, click the data source to be changed. You must click each individual table in the data source one by one. If the data source is a stored procedure you will not see individual tables.
NOTE In Crystal Reports 10, XIR1, and XIR2, if you are mapping from a data source such as a stored procedure where the report designer can not determine which fields should be mapped automatically, you will see a 'Mapping' dialog box where you can manually map fields, as in the procedure cited above.
3. In the 'Replace with' section, click the data source you want the report to use.
4. Click 'Update'.
5. Close the 'Set Datasource Location' window.
The report now points to the new location.
For Native Connections Only:
1. On the 'Database' menu, click 'Set Datasource Location'.
2. In the 'Current Data Source' section, click 'Properties' to expand it and right-click 'Database Name: <path to database>'.
3. Click 'Edit' and then type the path to the
new data source location.
4. Close the 'Set Datasource Location' window.
The report now points to the new location.

Retrieve available server names for MS SQL server

hello
Can somebody tell me how I can retrieve available server names for MS SQL server.
When MS SQL server loads it asks for server name to connect but on the same time has a combobox with the available server names(instace+database name). How can I provide the same functionality in my application?
Thank you in advance.

It isn't going to be as simple as just the name.
There are also different ways to connect and probably other parameters as well.
SQL Server Enterprise Manager probably uses a discovery protocol. It probably sends one or more messages requesting information and those servers that want to respond.
Note that none of that has anything to do with JDBC and discovering how it does that probably isn't easy. A packet sniffer might help.

Passing the database name as a PL/SQL procedure parameter

How do I pass the name of the database as a parameter to a procedure?
If dbs is the variable name to which I pass the database name as shown in the example,
CREATE OR REPLACE PROCEDURE Extract_gl_acct_Tbl(dbs varchar2)
and I use dbs in the code as follows,
SELECT ACCOUNT,
SETID
FROM SYSADM.PS_GL_ACCOUNT_TBL@dbs
It gives me an error saying 'ORA-04054: database link DBS does not exist'.

You will need to use dynamic SQL to handle this:
create or replace ...
is
type rc is ref cursor;
v_rc rc;
begin
open v_rc for 'select ... from sysadm.ps_gl_account_tbl@' || dbs;
fetch v_rc into ... -- some variables
-- if multiple rows, you'll need to do the fetch in a loop and exit when v_rc%notfound.
close v_rc;
end;

SQL script based on hostname and database name?

I am trying to write a script that I can run on several unix servers and databases that will do different sql statements based on which server and database it is being run in.
Something like:
if hostname = 'A' and database name = 'D' then do this
else if hostname = 'B' and database name = 'F' then do that
I have tried many diifferent combinations of shell scripts and sql scripts but can't seem to get anything that works.
Can someone help me out? Thanks.

Since you are already able to get he db and host info, you are well on your way to branching based on that information. All you need is the basic framework:
declare
db VARCHAR2(30);
host VARCHAR2(30);
sqlcmd VARCHAR2(4000);
begin
select sys_context('userenv','host') host
       , sys_context('userenv','db_name') db_name
    into host
       , db
    from dual;
case
    when db = 'XE' and host = 'mypc' then
      sqlcmd := q'[local_package.do_something('parm1', :db, :host)]';
      execute IMMEDIATE sqlcmd USING db, host;
    when db = 'DEV' and host in ('serv1','serv2') then
      sqlcmd := q'[different_packge.do_something('parm1', :db, :host)]';
      execute IMMEDIATE sqlcmd USING db, host;
    else
      dbms_output.put_line('unrecognized db/host combination: '||db||', '||host);
end case;
end;
/In this example I've used dynamic SQL since not all instances are guaranteed to have any or all of the package procedures referenced in the dynamic sql. With out the dynamic sql, you would get errors and be unable to run the script on any instance lacking one or more of the reference package procedures..

Can not connect the database via query string (C#). The SQL Server Management Studio is showing the full path of a location instead of database name.

I can not connect to the database via C#. The database is showing full path of the database file instead of the database name. See the pic: a database showing only name 'emart' and the other database showing the full path.
: Robby

Hi,
According to your post, I know that the database name is showing file path of the database rather than the database name in SQL Server Management Studio. You were not able to
establish a connection to the database using C#.
As Olaf said, was any error message thrown out when the connection failed? How did you create these databases?
You can use the following T-SQL to attach the database and see if the issue persists.
CREATE DATABASE
databasename
ON (FILENAME = 'filepath _Data.mdf'),
(FILENAME = 'filepath_Log.ldf')
FOR ATTACH;
Thanks.

Variable database name in SQL Server query using Oracle database link

Hi All,
I have an ApEx 4.1 app running on 11g x64 (11.2.0.1) on Windows Server 2008 x64, and I have some data integration points with a SQL Server (2005 and 2008) that I need to establish. I have configured the database link with dg4odbc and it works beautifully... I can execute queries against the SQL Server database without any problems using the database link.
However, there is a scenario where the SQL Server database name is dynamic, and I need to generate it on the fly in a PL/SQL block, and then use that in a dynamic SQL query (all of this in ApEx). This is where I run into problems... when I am querying the default database based on the ODBC connection and I don't have to specify the database name, there is no issue. But when I need to access one of several other non-default databases, I keep receiving the "invalid table" error.
This runs fine:* (note that "fv" is the name of my database link)
v_query1 := 'select "ReleaseDate" from dbo.Schedules@fv where dbo.Schedules."SchedID" = :schedule';
EXECUTE IMMEDIATE v_query1 into rel_date using schedule;
I then take that rel_date variable, convert to a varchar2 (rel_date_char), and then use it as the database name in the next query...
This returns an error_ (Error ORA-00903: invalid table name)
v_query2 := 'select "PARTNO" from :rel_date_char.dbo.ProdDetails@fv where "SchedID" = :schedule and "UnitID" = :unit
and "MasterKey" = :master and "ParentKey" = :parent';
EXECUTE IMMEDIATE v_query2 into part_number using schedule, unit, master, parent;
I have also tried using all of the following to no avail:
'select "PARTNO" from ' || :rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || @rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from @rel_date_char.dbo.ProdDetails@fv where "SchedID"...
Is there a way to do this in PL/SQL?
Thanks for any help!

=> instead of executing the statement using "execute Immediate" we have to use PASTHROUGH package to pass the statement to the SQL Server.

How can i identify the environment name or database name in the PL/SQL code

Hi,
I am using UTL_FILE to genearate the files.,
My problem is, I have to design the common sql file , which can be executed in 2 diffrent environments ( Say QA & DEV ) , with no parameters. It has to identify the environment and based on the environment , it has to generate the concern files.,
The only change needs to be incorporated is , file names , which will change based on the environment.,
can nay one tell me , how can i identify the environment name or database name in the PL/SQL code ??
Raja

In this case, USEC_GI_DEV.NA.XXXNET.NET is a TNS alias. That alias exists only on the client machine. There is no way to access that information on the database server.
You would have to find something in the v$database or v$instance table that uniquely identifies the database (and you may need some help from the DBAs to do this because you need to ensure that the data element you choose is compatible with whatever refresh process(es) are used in your environment).
Now, if you are writing a stand-alone SQL*Plus script, SQL*Plus, as a client tool, does have access to the TNS alias in later versions. But that is a client-side determination, not a server-side determination.

[Forum FAQ] How do i use xml stored in database as dataset in SQL Server Reporting Services?

Introduction
There is a scenario that users want to create SSRS report, the xml used to retrieve data for the report is stored in table of database. Since the data source is not of XML type, when we create data source for the report, we could not select XML as Data Source
type. Is there a way that we can create a dataset that is based on data of XML type, and retrieve report data from the dataset?
Solution
In this article, I will demonstrate how to use xml stored in database as dataset in SSRS reports.
Supposing the original xml stored in database is like below:
<Customers>
<Customer ID="11">
<FirstName>Bobby</FirstName>
<LastName>Moore</LastName>
</Customer>
<Customer ID="20">
<FirstName>Crystal</FirstName>
<LastName>Hu</LastName>
</Customer>
</Customers>
Now we can create an SSRS report and use the data of xml type as dataset by following steps:
In database, create a stored procedure to retrieve the data for the report in SQL Server Management Studio (SSMS) with the following query:
CREATE PROCEDURE xml_report
AS
DECLARE @xmlDoc XML;
SELECT @xmlDoc = xmlVal FROM xmlTbl WHERE id=1;
SELECT T.c.value('(@ID)','int') AS ID,
T.c.value('(FirstName[1])','varchar(99)') AS firstName,
T.c.value('(LastName[1])','varchar(99)') AS lastName
FROM
@xmlDoc.nodes('/Customers/Customer') T(c)
GO
P.S. This is an example for a given structured XML, to retrieve node values from different structured XMLs, you can reference here.
Click Start, point to All Programs, point to Microsoft SQL Server, and then click Business Intelligence Development Studio (BIDS) OR SQL Server Data Tools (SSDT). If this is the first time we have opened SQL Server Data Tools, click Business Intelligence
Settings for the default environment settings.
On the File menu, point to New, and then click Project.
In the Project Types list, click Business Intelligence Projects.
In the Templates list, click Report Server Project.
In Name, type project name.
Click OK to create the project.
In Solution Explorer, right-click Reports, point to Add, and click New Item.
In the Add New Item dialog box, under Templates, click Report.
In Name, type report name and then click Add.
In the Report Data pane, right-click Data Sources and click Add Data Source.
For an embedded data source, verify that Embedded connection is selected. From the Type drop-down list, select a data source type; for example, Microsoft SQL Server or OLE DB. Type the connection string directly or click Edit to open the Connection Properties
dialog box and select Server name and database name from the drop down list.
For a shared data source, verify that Use shared data source reference is selected, then select a data source from the drop down list.
Right-click DataSets and click Add Dataset, type a name for the dataset or accept the default name, then check Use a dataset embedded in my report. Select the name of an existing Data source from drop down list. Set Query type to StoredProcedure, then select
xml_report from drop down list.
In the Toolbox, click Table, and then click on the design surface.
In the Report Data pane, expand the dataset we created above to display the fields.
Drag the fields from the dataset to the cells of the table.

I have total four columns. On one page it should show three and the remaining one will be moved to next page.
Problem occurs when in my first row i have 3 columns and in next page if I have one columns then it show proper on first page but on second page also it gives me three columns insted of one. the first column data is exactly what I have but in remaining two
columns it shows some garbage data.
I have data like below.
Metric ColumnNo RowNo
1 1
1
2 2
1
3 3

so while grouping i have a row parent group on RowNo and Column group on ColumnNo.
can anyone please advice on this.

Roles cannot be used by pl/sql.
>
NOT TRUE!
That is an oft quoted myth. There are many posts in the forum that mis-state this.
Roles can be, and are used by PL/SQL. In fact, OP stated and demonstrated that in their question: their anonymous block worked.
The Oracle docs provide a very clear explanation - the core restriction is for NAMED PL/SQL blocks that use DEFINER's rights (the default):
>
Roles Used in Named Blocks with Definer's Rights
All roles are disabled in any named PL/SQL block (stored procedure, function, or trigger) that executes with definer's rights. Roles are not used for privilege checking and you cannot set roles within a definer's rights procedure.
>
The Database Security Guide has the information in the section 'How Roles Work in PL/SQL Blocks (which, of course, wouldln't be needed if they didn't work. ;) )
http://docs.oracle.com/cd/B28359_01/network.111/b28531/authorization.htm#i1007304
>
The use of roles in a PL/SQL block depends on whether it is an anonymous block or a named block (stored procedure, function, or trigger), and whether it executes with definer's rights or invoker's rights.
Roles Used in Named Blocks with Definer's Rights
All roles are disabled in any named PL/SQL block (stored procedure, function, or trigger) that executes with definer's rights. Roles are not used for privilege checking and you cannot set roles within a definer's rights procedure.
The SESSION_ROLES view shows all roles that are currently enabled. If a named PL/SQL block that executes with definer's rights queries SESSION_ROLES, then the query does not return any rows.
See Also:
Oracle Database Reference
Roles Used in Named Blocks with Invoker's Rights and Anonymous PL/SQL Blocks
Named PL/SQL blocks that execute with invoker's rights and anonymous PL/SQL blocks are executed based on privileges granted through enabled roles. Current roles are used for privilege checking within an invoker's rights PL/SQL block. You can use dynamic SQL to set a role in the session.

But when I was providing this value in weblogic.profile during patching attribute name "operationsDB.driver=oracle.jdbc.xa.client.OracleXADataSource ", I am getting this error
/data/oim/Oracle/Middleware/Oracle_IDM1/server/setup/deploy-files/setup.xml:204: java.lang.ClassCastException: oracle.jdbc.xa.client.OracleXADataSource cannot be cast to java.sql.Driver
So I changed this value to "operationsDB.driver=oracle.jdbc.OracleDriver" and it runs fine. Patch completed successfully.
Is there any issue with this Driver Class Name mismatch, so I am getting this error? I have also tried for all Datasources same Driver Class Name but invain.

Amit

Hi Bikash,
Nothing is changed between network/firewall. From Database machine I am able to see tnsping running fine. From weblogic admin console I have checked the connectivity of different datasource is successfull. Right now I have these datasources, all have Driver Class Name=oracle.jdbc.OracleDriver.
EDNDataSource
     EDNLocalTxDataSource
     mds-oim
     mds-owsm
     mds-soa
     oimJMSStoreDS
     oimOperationsDB
     OraSDPMDataSource
     SOADataSource
     SOALocalTxDataSource
You mean For all the datasources I need to make it oracle.jdbc.xa.client.OracleXADataSource. I make it this also but no success.
Also tell me..Summary of Security Realms >myrealm >Providers >OIMAuthenticationProvider here also I need to provide Xadatasource Driver name.
