Question

I can’t assign the result of query to variable (the program is written in C). Here is what I do

char buffer[100];

while ((row = mysql_fetch_row(res)) != NULL) {
   buffer = row[0];
}

A get this error during compile process

error: incompatible types in assignment

What is wrong here ?

Answer 1

Assuming it’s a string? C doesn’t have strings it has arrays of characters. So you have copy the characters from one array to another.

so use a copy function like

strncpy(buffer, row[0], 100);
