SQL insert error

I have a site that when I entered a product, I get this error message trying to add tags. The XXXXX_contentitem_tag_map table was completely empty but I went ahead and did a repair / optimize on the table. I tried again and got the same message. In both cases, the product record was saved in the XXXXX_hikashop_product table but nothing displays in the administrator side nor on the front public display for the product category. So I deleted both records from the product table and re-entered without any tags. The product was entered proper and does display now.

Nicholas,

It is still creating the error message. If I put anything in the 'tags' field, I get the error. If I leave the 'tags' field empty, it works as it should. Just to let you know, it does create the product record but it doesn't appear anywhere either in the frontend or the backend. It's like it never got indexed or linked.

Here is the example of what I tried to add when I got the error message.

Nicholas,

I used AdminTools to do a repair/optimize on the tables, used ACL Manager to check linkage (all green) and edited an existing product item to add tags. I got the same error message. Repaired/Optimized again, check ACL and tried to create a new product. Same error message. Something is really screwed up. I can live without tags but if this is messing up, what else could be going wrong with linkage.
