Hi, I'm trying to add sequence of tags to a list subjects.
I wouldn't make unique tag
column field because I may have the same duplicate depending by the user language like in the example
table_houses
id name location
1 Victoria's Home New York
2 Black Mesa Lab New Mexico
3 Tube London
table_tags
id tag id_subjects language
1 garage 1 it
2 garage 2 fr
3 research 3 en
4 lab 3 en
5 laboratorio 3 it
6 garage 1 it <== how to avoid this duplicated INSERT like first row?
I've saw some example where people uses INSERT IGNORE INTO
statement but I've got It works only with unique columns and it is used to skip duplicate errors.
Does exist some way to skip duplicate tags for the same language only?
