Description
The TABLEMETADATA() function is used to return the METADATA string from the Active Data Dictionary associated with the active table. This can be a JSON encoded complex object containing properties that are arrays of objects or nested objects. You can change the elements of the metadata object then update the Active Data Dictionary with the new metadata.
Example
open database southwind use customers omd = json_decode( tableMetaData() ) omd.searchpanelvisible = .t. use alter table customers metadata json_encode(omd)
