This topic provides a typical scenario of using Meta Query to fetch data in a custom way from your MMDB.
Try the following sequence of steps:
| 1. | Navigate to MMDB Schema Tree. Browse the structure of your MetaMiner Database and find the table(s) and column(s) you need. |
| 3. | Optionally, fetch the information from a selected table or column (for example, the CLASSNAME column in the WEBI1200_DOCOBJECTS table) with the Show Column Values command. This command opens a new script tab in the SQL Script Pane and creates a simple SQL query, for example: |
SELECT DISTINCT CLASSNAME from WEBI1200_DOCOBJECTS
| 4. | Then Meta Query automatically runs this script, and the content from MMDB fetched by this script opens in the Results Pane: |
| 5. | Now you see both structure and current content of the table you need. |
| 6. | Switch to the SQL Script Pane. You may want to use the automatically generated script as a draft for your own custom script, or you may want to create a  New script, or  Open Script Catalog and choose one of the existing scripts from the catalog, or  Load from a file. |
| 7. | Edit and run your custom SQL script. Browse output in the Results Pane. Find the information you need. |
| 8. | When you are done, save your script for future usage by clicking  Save to Catalog or  Save (to a file). |
