all about quotes

[Tim Davis]

Hello everyone,

    I need to get clear on how Valentina handles quotes in SQL 
statements.

1. What is the difference between using single quotes and double quotes 
marks to surround literal strings in SQL statements?

2. What is the best way to escape quotes within, beginning or ending an 
SQL statement's literal string value, with repeating quote marks or the 
"\" character?

3. Are there any other characters in an SQL statement literal string 
values (other than quote marks) which requires escaping with "\" so it 
doesn't mess with interpretation?

Thank you very much!
Tim Davis
