引用另一个单元格中一个单元格的值（SQL）

Question

I am not sure if this is possible. I have done a lot of searching but I keep finding answers about inserting a value one time, not keeping a reference.

At my work I am 'internationalising' some webpages, which means making a database entry for every piece of text. There is one piece of text that has a link in it, and the link is stored in the database already. Having the code that referenced the link in the database cell didn't work (it just printed out as plain text), so my solution was to have the first half on the paragraph as one database entry (ending in ...<a href=" ), and the second half as another (starting with ">click here</a>...), and have the reference to the link in the middle. However my supervisor didn't like that.

So, what I would LIKE to be able to do, is have one database entry for the whole paragraph, and in the middle of it, refer to the link which is in another table (actually the same table, different sub-table). That way, the link will stay updated if it is ever changed (rather than hard-coding it into the paragraph text).

If it is impossible, that's totally fine, just want to confirm it (I can't seem to find anyone else who wanted to do this same thing and has been told it's impossible).

Thanks!

This is totally possible. All you need to do is to design a trigger on the table at insert and update event. whenever the link is entered or updated, the trigger will update the paragraph column as per your coding inside the trigger.

If you can share the table and fields, I can help you to write that trigger too :)
