In dolphindb,I can create an in-memory table in dolphindb like: t = table(1 2 3 as id); And I can use sql statements at it. But I don't know the right way to delete it.The function

dropTable(dbHandle, tableName)

can only drop the table in database.. And the function

drop(X, n)

can only drop some rows of the table X

In DolphinDB, you can use undef to release variables or function definitions from the memory. A in-memory table like: t = table(1 2 3 as id) can be deleted in this way.
