mysql: replace \ (backslash) in strings

Question

I am having the following problem:

I have a table T which has a column Name with names. The names have the following structure:

A\\\\B\\C

You can cre

Answer 1

The literal A\\B\C must be coded as A\\\\A\\C, and the parameters of replace() need escaping too:

select 'A\\\\B\\C', replace('A\\\\B\\C', '\\', '\\\\');

output (see this running on SQLFiddle):

A\\B\C         A\\\\B\\C

So there is little point in using replace. These two statements are equivalent:

select Name from T where Name = replace('A\\\\B\\C', '\\', '\\\\');
select Name from T where Name =         'A\\\\B\\C';
