Provides a way of displaying the field comments (metadata) from databases and spreadsheets. Field names not present in the app will be ignored. If multiple occurrences of a field name are found, the last value is used.
Syntax:
comment [fields] *fieldlist using mapname
comment [field] fieldname with comment
The map table used should have two columns, the first containing field names and the second the comments.
Arguments:
| Argument | Description |
|---|---|
| *fieldlist | A comma separated list of the fields to be commented. Using * as field list indicates all fields. The wildcard characters * and ? are allowed in field names. Quoting of field names may be necessary when wildcards are used. |
| mapname | The name of a mapping table previously read in a mapping LOAD or mapping SELECT statement. |
| fieldname | The name of the field that should be commented. |
| comment | The comment that should be added to the field. |
Example 1:
commentmap:
mapping LOAD * inline [
a,b
Alpha,This field contains text values
Num,This field contains numeric values
];
comment fields using commentmap;
Example 2:
comment field Alpha with AFieldContainingCharacters;
comment field Num with '*A field containing numbers';
