Modify column metadata in a table
You can modify column metadata after the SQL Metadata Tool analyzes the table.
You must have a schema and a table selected before you modify column metadata.
If you used auto-populate to create tables or added tables and columns manually, the SQL Metadata Tool analyzes the tables and assigns SQL metadata. However, you may override the default column metadata.
- Navigate to the Columns tab.
 - In the Column name drop-down list, select the column you wish to modify.
 - 
                Rename the column, if desired. 
                SQL column names are not subject to the same constraints as 1010data column names. For example, SQL column names may contain spaces and special characters.
 - In the Underlying column drop-down list, select a different 1010data column, if desired.
 - In the MDB type drop-down list, select a different MDB type, if desired.
 - In the SQL type drop-down list, select a different SQL type, if desired.
 - In the Cardinality field, modify the number of unique column entries, if desired.
 - 
                Select one or more of the following flags for your table:
                        Unique, Sorted,
                        Indexed, Nullable, or
                        Case-insensitive.
                The SQL Metadata Tool sets these flags when it analyzes the column data, but you can override the default settings.
See Columns for more details.
 - Click Save changes to this column to save the column metadata.
