UPDATE your_table
SET your_field = REPLACE(your_field, 'old_value', 'new_value')
WHERE your_field LIKE '%old_value%'

have you ever had a database table that you needed to clone? you can use any number of convoluted methods such as: manually coping and pasting rows in the database manager, running lots of queries/stored procedures, or writing a script to cycle though each row copying data from one table to the next. all of these methods are inferior and far more complex then the method i'm going to show you.

introducing the select into query...
this method should be used if the table you want to clone exists, but the new table douse not. the select into query will create the new table for you, copying all the column names, properties, and data. if you want to make an exact clone of the table you can select * into the new table. but if you only want a few specific columns, you can declare only the ones you want. the syntax is elegantly simple...

SELECT *
INTO [new-table]
FROM [old-table]

sometimes it’s true, you actually do need two queries to get the job done. but other times you can circumvent this by using something like a "join" or "inner join" query to merge two tables together and pull your results from both.

but the optimizer in you says that still isn’t enough...

the first thing is creating a connection with your database. if you understand how connection strings are built, write your own other wise will can use the visual studio database tool to do that for us.
