Update trouble

[Kate Legere]

I'm trying to retrieve a certain ID row from a table and use Update to
insert it into a specific row of another table. I'm not getting any syntax
error but I'm also not getting the update to work


UPDATE linksProjects LEFT JOIN categories ON linksProjects.categoryId =
categories.categoryId SET linksProjects.categoryId = categories.categoryId
WHERE categories.catTitle = 'Vision';
