Class: TMMConnection
function GetTablesColumns(const ATableNames: TArray<string>; out AResult: TDictionary<string, TMMColumnInfoArray>): Boolean;Retrieves column metadata for multiple tables in a single HTTP
call.
AResult maps each table name to its
TMMColumnInfoArray; the caller must free the returned
TDictionary. Dictionary keys are normalised to lowercase,
so lookups must use LowerCase(TableName) to match correctly
(relevant when the server runs with
lower_case_table_names = 2).
Returns False on network or server error;
AResult is nil on failure.
