W_table_n_dim W_table_1_dim W_tables_2_dim ......... ........ W_table_n_dim ABC_W_table_1_fact ABC_W_tables_2_fact ......... ........ ABC_W_table_n_dim ABC_W_table_1_dim ABC_W_tables_2_dim ......... ........ ABC_W_table_n_dim </code></pre> <p>Now the tables with prefix ABC have their data and columns taken from original tables with exception of few missing columns and maybe some data(which don't care about for now) .I need to check if the columns we need have been loaded in the tables with prefix ABC.So I need to make a query that tells me which columns are missing can anybody please help me make a query.If you need any information please feel free to ask i will give any required information.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
