Table/Column Alias

If you happen to create a report that extracts information from different tables such as the Assets, Requests, Asset Types tables, then you would have some fields with the same column names. This in itself is ok except if you are trying to read a report, you would confuse field names. This is where table and field aliases come in. In the example below, we are using SQL Schema Designer and four tables: h_itsm_requests, h_cmdb_assets, h_cmdb_asset_types and h_cmdb_links.

You could add an alias for a table such as h_cmdb_asset_types simply because the table name is very long and you wish to shorten it for reference elsewhere. You can do this by double clicking on the table name on the Select Tables tab. Then you should see the option to 'Add Alias' or 'Remove Table'



In tables such as h_cmdb_assets you have a column called h_name. Similarly in table h_cmdb_asset_types, you also have a column called h_name so in order to create a report with these two tables, to avoid confusion, you can use field aliases to differentiate between the two fields.


In the above illustration, Asset Name(h_cmdb_assets.h_name) could easily be confused with h_cmdb_asset_types.h_name. If you remember h_cmdb_asset_types was aliased to AssetTypes so in the diagram this is showing as AssetTypes->TypeName(AssetTypes.h_name)


By clicking on the Edit Report Columns shown with an Edit icon(pencil) you can add an alias for the field name.

The end result is a report such as the one below:
