c# - How to do a simple OR query with LINQ? -

i using linq entities , i'm trying simple or query. have table called "links" , when run query want include links containing tag list of tags , links matching search term. example:

var tags = new list<string> { "games", "events", "recipes" }; var searchterms = new list<string> { "hockey", "barbecue", "cheesecake", "basketball" } var links = _entitycontainer.links .where(x => x.tags.any(y => tags.contains(y.name)) .where(x => searchterms.any(y => x.title.contains(y)));

note: link entity has navigation property called tags in first .where() i'm checking each of tags in link's collection see if list of tags i'm searching contains 1 of them.

in sec .where() i'm checking if link's title property contains of search terms.

my problem code includes links contain @ to the lowest degree 1 tag list , match 1 of search terms. want include both together. want links list include links either match 1 or more tags in list or match 1 or more search terms in list.

i have issue because of tags.contains() , searchterms.any() because these calls cannot converted expressions passed ef. work if did tolist() cannot pull big number of records memory.

any suggestions accomplishing goal? help much appreciated.

condense 1 clause:

var links = _entitycontainer.links .where(x => x.tags.any(y => tags.contains(y.name)) || searchterms.any(y => x.title.contains(y)));

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
