Char ' or " in sql statement

Question

Hi,
How to build the sql statement
update myTable set myColumnName='myValue'
when myValue contains ' characters ?
I tried a replaceAll( "'", "\'") but it doesn't seems the solution.

Answer 1

it will not fail, it just does something slightly different. my code was designed to only replace a single quote as the op requested. it was mot meant to change two single quotes as part of my string was to have already been escaped. admitidly this might not be what the OP wants.
public static void main(String[] args)
          String content = "This is a 'string''";
          System.out.println("content = " + content);             // content = This is a 'string''
          content = content.replaceAll("(?<!')'(?!')", "''");
          System.out.println("content = " + content);             // content = This is a ''string''
}your code
public static void main(String[] args)
          String content = "This is a 'string''";
          System.out.println("content = " + content);        // content = This is a 'string''
          content = content.replaceAll("'", "''");
          System.out.println("content = " + content);        // content = This is a ''string''''
