Using output from Solve or Reduce as a value in subsequent equation

I’m trying to run a simulation. I will number sentences to make response easier. (1) Here is my first equation:

𝑗[LBar_, y_, x1_, σ_, X2M_, w_, X1M_]:=(LBar(𝜎−1)⁄𝜎 + 𝑦(𝜎−1)⁄𝜎−x1(𝜎−1)⁄𝜎)𝜎⁄(𝜎−1)−(𝑦−X2M+𝑤(LBar+X1M)−𝑤x1) 

(2) I insert some parameter values and Reduce:

Reduce[𝜕x1(𝑗[100,𝑦,x1,13⁄,42,.23,80])==0 && x1>0, x1, Reals] 

(3) This produces output:

x1 == 119.575 

(4) When I try to call the output value (119.575) I run into problems. (5) For instance

2 % 

results in:

2 (x1 == 119.575) 

(6) and

j[100, 80, %[[2]], 1/3, 42, .23, 80] 

produces this output:

-79.4 + 1/Sqrt[41/160000 - 1/239.149[[2]]^2] + 0.23 239.149[[2]] 

If a PC becomes stunned on their turn, do they lose the rest of their actions without losing any stunned value?

Page 622 of the Core Rulebook defines the Stunned condition:

You’ve become senseless. You can’t act while stunned. Stunned usually includes a value, possibly over multiple turns, from being stunned. Each time you regain actions (such as at the start of your turn), reduce the number you regain by your stunned value, then reduce your stunned value by the number of actions you lost. …

I’ve created a creature that can stun a PC as a result of the PC attacking it with a melee weapon. This means that the PC could be stunned mid-turn.

Now, rules as written, the above paragraph reads like this:

  1. You can’t act when stunned.
  2. Stunned value "ticks down" each time you regain actions.
  3. Therefore, if you are stunned during your turn, "you can’t act," so you simply lose your remaining actions. Then, at the start of your turn when you regain actions, Stunned ticks down and you may be able to act again on that turn if Stunned reduced to zero.

So, if a PC takes their first action and become Stunned 1, they will actually lose a total of three actions: the remaining two actions on their current turn, then one action when they regain actions next turn.

Is this the correct interpretation? Or should Stunned start ticking down immediately, so that in the above example, the PC would lose their second action on that turn, go down to Stunned 0, and then be able to take their third action?

Update variable value via add_filter

I have this apply filter in my plugin.

$  pre_html = apply_filters( 'events_views_html', null, $  view_slug, $  query, $  context ); 

I want to change $ view_slug value dynamically because I do not want to modify plugin files. Can I do this using add_filter in my child theme ?

It is a basic question but I have limited knowledge of WordPress filters and hooks. Some guidelines regarding this will be appreciated.

How can I call a SQL Server stored procedure from Oracle and retrieve a scalar return value?

I’m developing a PL/SQL solution in Oracle Database Enterprise Edition 12.1.0.2. I’m calling stored procedures in Microsoft SQL Server 2014.

I am using DG4ODBC with the DBMS_HS_PASSTHROUGH package to call those stored procedures.

For stored procedures that return a tabular result set, I am able to use PARSE, FETCH_ROW, and GET_VALUE to retrieve the values. (My solution uses hard parsing, but it works for the volume we’re expecting. I’m open to tips if you know how I can use binds, but that’s not my question.)

DECLARE    sql_server_cursor_     BINARY_INTEGER;    sql_server_statement_  VARCHAR2(32767);    fetched_value_col1_    whatever_type_from_col1;    fetched_value_col2_    whatever_type_from_col2; BEGIN    sql_server_statement_ := 'EXEC "myDatabase"."dbo"."myProcedure" @p_one = N''' || sanitize__(my_argument_) || ''';';    sql_server_cursor_ := dbms_hs_passthrough.open_cursor@sql_server_link_;    dbms_hs_passthrough.parse@sql_server_link_(sql_server_cursor_, sql_server_statement_);    WHILE dbms_hs_passthrough.fetch_row@sql_server_link_(sql_server_cursor_) > 0    LOOP       dbms_hs_passthrough.get_value@sql_server_link_(sql_server_cursor_,  1, fetched_value_col1_);       dbms_hs_passthrough.get_value@sql_server_link_(sql_server_cursor_,  2, fetched_value_col2_);       dbms_output.put_line('fetched_value_col1_  ' || fetched_value_col1_);       dbms_output.put_line('fetched_value_col2_  ' || fetched_value_col2_);    END LOOP;    dbms_hs_passthrough.close_cursor@sql_server_link_(sql_server_cursor_); END; / 

I have a stored procedure in SQL Server that returns a scalar integer.

DECLARE @return_value int; EXEC @return_value = "myDatabase"."dbo"."myProcedure" @p_one = N'HelloWorld', @p_two = 42; SELECT @return_value; 

From Oracle, how would I call this procedure and retrieve that scalar value?

Select arbitrary single value for GROUP BY: What’s the fastest option?

I have a query that I use to indicate locations in a map where there are overlapping points:

select     min(objectid) as min_objectid,     longitudex,     latitudey,     count(1) as count,     min(shape) as min_shape from     workorders group by     longitudex,     latitudey having     count(1) > 1 

In the mapping software that I use, I need to include columns like objectid and shape. For those columns, it doesn’t matter which of the grouped-by rows the values come from, just as long as there is a value.

Presently, I’m using min() to get an arbitrary value for those columns. However, I don’t know if that’s the fastest option since finding the minimum value would require calculation — and I wonder if that time spent is unnecessary.

What is the fastest option for getting an arbitrary/single value for GROUP BY in an Oracle query?

SQL daily value (today value – yesterday value)

I have a database where there are sales .

+----+-----------+------------+ | ID | Quantity  |    DATE    | +----+-----------+------------+ | 1  |       40  | 2020/10/10 | | 2  |        0  | 2020/10/01 | | 3  |       10  | 2020/10/11 | +----+-----------+------------+ 

And i want this result :

+------------+----------+------------+ | OPERATION  | Resultat |    DATE    | +------------+----------+------------+ | 40 - 0     |      40  | 2020/10/10 | | 0 - 40     |     -40  | 2020/10/01 | | 10 - 0     |      10  | 2020/10/11 | +------------+----------+------------+ 

I mean get the sum of the value of datevalue of yersterday

could someone give me an idea of how i could write this simply? Thank you in advance

What is the highest value a condition could reach?

I’m making a Pathfinder 2e character sheet on Google sheet to automate as much number-crunching as possible. Currently, I’m making a dropdown list for conditions, as well as formulas for calculating their penalties.

I find adding conditions with pre-determined values much simpler than conditions with fillable values. For example, instead of clumsy and a blank slot for its value, the dropdown list will have clumsy 1, clumsy 2, clumsy 3, and so on. It’s ugly, but it greatly simplifies the formula. However, if a condition’s value could reach a really high number, then it will be too cumbersome to use.

The highest I have found is stupefied 4 from feeblemind and unfathomable song. I’m also pretty sure I’ve seen an ancestry/heritage/feat which could increase the maximum value of dying to 5.

So what is the highest value/penalty a condition could reach? For the supremely meticulous: what is the highest value each condition could reach?

Post pagination links ordered by meta value

Is there a way to order the nex-previous post links, or any other pagination function to get the links ordered by meta value, like I have done in the posts listing page shown below?

$  events = get_posts(array(     'posts_per_page' => -1,     'post_type' => 'post',     'meta_key'  => 'date_time',     'orderby'   => 'meta_value',     'order'     => 'ASC',     'suppress_filters' => false )); 

The main goal is tho have the next, – previous event buttons in chronological order in the single post page. (not the post date, but the event date that is stored in custom fields)

options.php does not save option value to database

seems it is duplicate question but i tried the existing solution and still not solved my problem. i creating the test plugin and i have problem in submitting value to options.php which is not store the value to corresponding option and still is null.

this is how i registered my option settings.

public function registerCustomFields(){          register_setting( 'opt_grp', 'last_name',array($  this->callBacks,'pluginOptionsGroup'));         add_settings_section( 'section_index', 'section title', array($  this->callBacks,'pluginSectionCB'), 'adm_menu' );         add_settings_field( 'last_name', 'test text', array( $  this->callBacks, 'pluginTextExample' ), 'adm_menu', 'section_index');     } add_action('admin_init',array($  this,'registerCustomFields')); 

and here is above callbacks

public function pluginOptionsGroup($  input){         return $  input;     }      public function pluginSectionCB(){         echo "Feachures Management";     }      public function pluginTextExample(){         $  value = get_option('last_name');                  echo '<input type="text" class="ui-toggle" id="last_name" name="last_name" value="'.$  value.'" >';     } 

and this is the form in myadmin.php page

<div>         <?php settings_errors(); ?>      <form type="POST" action="options.php">         <?php              settings_fields( 'opt_grp' );                          do_settings_sections( 'adm_menu' );                          submit_button();                          ?>               </form>  </div> 

i can find the option in option table but its always null,and when i change value in database itself its ok and by refreshing page it comes to textbox
