I am sending a sql statement that is doin an insert - the values that are going into the table come from another query and therefore come as: john's - I need to double up the qoutes and can't simply do a john''s or a john\'\'s.

Given a string with one apostrophe I need to replace it with two apostrophes.

Programming in C (pro*c).

Thanks
Dave

char* double_apostrophes ( const char* src, char* dst, unsigned dstsize) {

    unsigned count = 0;
    while ( *src && count < dstsize) {

    *dst = *src;

    if ( '\'' == *src) ++dst, *dst = *src;

    ++src;
    ++dst;
    ++count;

Have you tried this.  

>>Given a string with one apostrophe I need to replace it with two apostrophes.


for( i = 0; i < strlen( string1 ); i++, j++ )
{
   string2[j] = string1[i];
   if( string1[i] == '\'';
   {
       j++;
       string2[j] = '\'';
    }
    string2[j+1] = '\0';
}

Hope this helps.

I had already used the first answer and just didnt get a chance to get back to it - if the admin reads this he can take 50 points from me and give them to "jonathan6587" - I should have responded earlier.

Thanks for the help,
Dave

jkr.  

    Sorry.  I thought maybe my answer was a little more straight forward.  But NO it isn't really any different functionally.  Some people get confused when trying to work with other peoples functions, but in the end that is what DAVE would have needed.
