The elements created in Virtual DataPort can be organized in folders. These are: data sources, stored procedures, wrappers, views, Web services and widgets.
Although these elements can be organized in folders, you cannot create two elements with the same name in a database, even if they are located different folders.
CREATE [ OR REPLACE ] FOLDER <folder_name:literal> [ DESCRIPTION <description> ]
folder_name is the full path of the new folder. That means that this
parameter has to start with the character
/. For example
CREATE FOLDER '/folder1'.
If you want to create a subfolder
/folderA/subfolderA, you have to
create the folder
folderA first and then, the
CREATE FOLDER '/folderA' CREATE FOLDER '/folderA/subfolderA'
To manage an existing folder and its contents, use the statement
ALTER FOLDER. With
it, you can do the following actions:
Change the description of a folder:
Rename a folder:
Move a folder to a different location
Move an element (data source, view, etc.) to another folder
Copy an element (data source, view, etc.):
ALTER FOLDER COPY…
ALTER FOLDER <source folder name:literal> <operation> <operation> ::= RENAME <target folder name:literal> [ DESCRIPTION <description:literal> ] | DESCRIPTION <description:literal> | MOVE <element> <name:identifier> | COPY <element> <element old name:identifier> AS <element new name:identifier> <element> ::= DATASOURCE <datasource type> | WRAPPER <wrapper type> | TABLE | VIEW | STOREDPROCEDURE | WEBSERVICE | WIDGET <data source type> ::= ARN | CUSTOM | DF | ESSBASE | GS | JDBC | JSON | LDAP | ODBC | OLAP | SAPBW | SAPBWBAPI | SAPERP | WS | XML <wrapper type> ::= <data source type> | ITP
To change the description of a folder, execute the command
ALTER FOLDER <folder-name> DESCRIPTION....
ALTER FOLDER '/folder for data sources' DESCRIPTION 'This folder will contain data sources';
To rename a folder, execute the command
ALTER FOLDER <folder-name> RENAME...
The following statement changes the name of the
folder for data sources to
ALTER FOLDER '/folder for data sources' RENAME '/folder_for_ds';
You also have to use this syntax to move a folder into another folder.
The following statement moves
/folder_for_ds into the folder
ALTER FOLDER '/folder_for_ds' RENAME '/folderA/folder_for_ds';
To move an element to another folder, execute
ALTER FOLDER <folder_name> MOVE... being
Depending on the element that you want to move, you have to use the
moving base views),
VIEW (for moving combined views), etc.
The following statement
moves a data source JDBC into the folder
ALTER FOLDER '/folderA' MOVE DATASOURCE JDBC ds_jdbc_internet_inc;
To copy an element, execute the command
ALTER FOLDER <folder_name> COPY... being
target folder for the new element. The syntax is similar to
ALTER FOLDER ... MOVE, but with
AS <element new name:identifier>
at the end to indicate the name of the target folder.
Remember that you cannot create two elements in the same database, with the same name and type, even if they are in different folders.
The following statement copies a Web service
data source into the folder
ALTER FOLDER '/folderA' COPY DATASOURCE WS ds_ws_sales AS ds_ws_sales_2;
DROP FOLDER... statement to delete a folder (see Syntax of the DROP statement)
