sql - MySQL join based on regexp -

-

I have table product where is a related product from the column . Related products contain colored materials ID ( column productivity ) by colon, e.g. Abc-123: foo-prod: ada69, etc. Due to some poor design, there is a case that a product can be removed from the product table and the relevant products can still be referred to in the column.

So I need a SQL query, which goes through all the rows in the table of products, explodes the data and checks the related product columns (hence the title is exploded) and it Observe whether each reference product exists in the same product table. However, I am a newbie on SQL and there is a problem writing the join / regexp query to do this.

Any help would be appreciated!

MySQL mail regexp , But unfortunately can not return the matching substrings.

You better select from the product P zone product from FIXIN_SET (rel.id, repplace (p.related, ':', ',' '))

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
