You may come across the below error message while running a DDL command from a client on a published resource in TIBCO Data Virtualization. 
---------------------------
[Code: 1906510, SQL State: ]  An exception occurred when executing the following query: "CREATE TABLE AAKASH(PID BIGINT, EID BIGINT)".  Cause: DDL support has not been configured. [Log ID: dc4c41c4-aa53-46aa-a577-e0151b54189a] [jdbc-1906510]
---------------------------

In the above example, the below query was run to create a table in the end database. The query was run from a JDBC client tool - DbVisualizer. 
---------------------------
CREATE TABLE TEST(PID BIGINT, EID BIGINT);

1. Go to the published resource. e.g. /services/databases/snowflake
2. Right-click and open the database.
3. Select the Composite DDL tab from the database page.
4. Specify the physical data source container paths for which needs to be mapped to published catalogs and schemas.
5. Browse to select the Database physical container path. e.g. /shared/Test/Snowflake-Div-InHouse/ds_snowflake-Test/TEST_DB/TEST
6. Be specific while defining the path. If the path does not contain a leaf container then an error message can be seen while running the DDL command. e.g. If the path is specified till the datasource name itself - /shared/Test/Snowflake-Div-InHouse/ds_snowflake-Test
