如何为静态数组的内容分配指针数组？

char myData[505][3][50];   //2D array, each 50 chars long   
char **tableData[505] = {NULL};  

const char* text;
text = sqlite3_column_text(stmt, col_index);

strcpy(myData[row_index][c_index],text); 

tableData[row_index] = myData[row_index][c_index]; <--?  
char myData[505][3][50];   //2D array, each 50
