Experts-

I have string responses stored in my table.  Some of the responses contain "dbmSnippets" within the response string.  I would like to find all of the dbmSnippets and replace them with \' keeping the rest of the response in tact.  Any suggestion on how to do this would be appreciated.

Thanks
Nick

Thanks Net.

 Will that keep the rest of my string intact?  So if my string looks like,
Yes~I agree that JuliadbmSnippetss quadlateral performance"  Will it simply replace the dbmSnippets to look like...
"Yes~I agree that Julia's quadlateral performance"

It looks like the current query is replacing it with a slash '\' -- update the code to be REPLACE(response, 'dbmSnippets', '\'') and it will result in only the dbmSnippets being replaced. The rest of the string will be untouched.

No, it will not. I have thought you want \, not '.

You need:
UPDATE tablename SET response = REPLACE(response, 'dbmSnippets', "'") WHERE response LIKE '%dbmSnippets%';

WHERE response LIKE '%dbmSnippets%' will look for all rows for which a column response contains dbmSnippets.

REPLACE(response, 'dbmSnippets', "'") will produce a string that will be a content of response with all dbmSnippets replaced with '.

Before you run it over your production table, create a test table and try the query on it.

Just put what you want as the third parameter for REPLACE.

Net, I'm looking for a slash and an apostrophe so the replace will be /'

Thanks

You are not limited to a single character. Try:

UPDATE tablename SET response = REPLACE(response, 'dbmSnippets', "/'") WHERE response LIKE '%dbmSnippets%';
or
UPDATE tablename SET response = REPLACE(response, 'dbmSnippets', '/\'') WHERE response LIKE '%dbmSnippets%';

Hey Net,

Sorry for the confusion.  So, I'm looking to use \' and not the back slash/.  Now I tested it on a couple of results, but it's taking the dbmSnippets out but only replacing it with a ' instead of \'....

Here is a reference on escaping special characters in MySQL:
http://dev.mysql.com/doc/refman/5.0/en/string-syntax.html

Manual on REPLACE:
http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

What you want is:
REPLACE(response, 'dbmSnippets', '\\\'')
