Question

Version MySQL: 5.5.28
phpMyAdmin – 2.11.11.3

I have multiple records of the type: name_test/, name_test/etc, name_test/etc/etc name_test/etc/etc/etc/etc and I want them to be like Top/name_test/, Top/name_test/etc, Top/name_test/etc/etc/, Top/name_test/etc/etc/etc/etc .

90% of them have already changed so we need to SELECT only those record that start with “name_test/”
problem is a problem is a bit more complicated, i you have to change some 4 million filds.

**table exemple1**

**column1**             **column2**                 **column3**
name_test1              name_test2/etc              name_test3
Top/etc/etc/            Top/name_test2/etc/etc/     name_test/etc/etc/
name_test               Top/name_test/etc/
name_test               #name_test/etc/etc/etc/#
name_test               #name_test/etc/etc/#
name_test2              #name_test/etc/#
name_test5              #name_test/#
name_test/etc

I have other tables with language like this:

**table exemple2**

**column1**             **column2**                 **column3**
name_test1              italian:name_test2/etc              name_test3
Top/etc/etc/            english:Top/name_test2/etc/etc/     name_test/etc/etc/
name_test               Bulgarian:Top/name_test/etc/
name_test               Danish:#name_test/etc/etc/etc/#
name_test               Korean:#name_test/etc/etc/#
name_test2              Russian:#name_test/etc/#
name_test5              etc:#name_test/#
name_test/etc

Note: only this #filds# must be modified in the example

other records that start otherwise not be modified
Any help would be appreciated!

This should work for you:

UPDATE table
SET column2 = concat('Top/', column2)
WHERE column2 LIKE 'name_test/%'
