Changeset: 2a9ae757e881 for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB/rev/2a9ae757e881
Modified Files:
sql/storage/bat/bat_utils.c
Branch: Jul2021
Log Message:
Load bat if type wasn't filled in yet by the lower layers.
This fixes a problem where e.g. a 'DELETE FROM t' fails when it is the
first operation on 't' after startup, and t contains a type such as
BLOB that isn't a core GDK type.
