    <p>So I ve got this: char table1[10^length][length]; char table2[10^length][length];</p> <p>And compiler doesn't let me dot this: table1=table2;</p> <p>my code is supposed to take a string with wild caracters (only ?)</p> <p>and give all the possible strings in the output (well it is a part of a bigger project but lets say print them in terminal - if I do this I can handle the rest)</p> <p>Here is the full code:</p> <pre><code>int ** wildReplacement(char *wildAM,int length) { length=7; char * temp; strcpy(wildAM,"123?23"); //getchar(); int i=0; int j=0; int k=0; int l=0; int limit=0; int wildCharsNum; char *nlptr= NULL; char table1[10^length][length]; char table2[10^length][length]; wildCharsNum=charOccurenciesInStr(wildAM,'?'); strcpy(temp,wildAM); strcpy(table1[0],wildAM); printf("\n!!WildChars In wildAM:%d",wildCharsNum); while(k&lt;wildCharsNum) { l=0; while(l&lt;=limit) { strcpy(temp,table1[l]); i=0; nlptr = strchr(temp, '?');//ka8e fora vriskei to epomeno ? if (nlptr) { for(j=1;j&lt;10;j++) { *nlptr = myItoc(j);//antikatastasi tou ? me digits sto temp strcpy(table2[i],temp); i++; } } l++; } table1=table2; limit=i; k++; } printf("\nWild Numbers out:"); for(i=0;i&lt;limit;i++) { printf("\n%s",table1[i]); } } </code></pre> <p>Should I malloc like:</p> <pre><code>char ** table1 char ** table2 table1=malloc(sizeof(char)*10^length*lenght) table2=malloc(sizeof(char)*10^length*lenght) </code></pre> <p>How would the programm know when each record ends</p> <p>Then what would this mean: table1[1] ? probably nothing...</p> <p>Thanks in advance</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
