A table school

and is the table newemails

Objective - E-mail addresses from the table newemails in the school♪
The point is, to deal with such tasks, I write a separate annex. But I think that's a standard SQL tool. Is there a possibility?

UPDATE s
   SET s.SchoolEmail = e.SchoolEmail
  FROM school s
 INNER JOIN newemails e
       ON   s.SchoolID = e.SchoolID

You can use try-catch inside the sp:BEGIN TRY SELECT 1/0; END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage; END CATCH; If you want to force an error depending on the logic of the sp, use the https://docs.microsoft.com/pt-br/sql/t-sql/language-elements/raiserror-transact-sql?view=sql-server-2017 If you are using an older version of SQL Server, you can open a transaction and commit or rollback according to a condition or error.DECLARE @E INT BEGIN TRAN SELECT 1/0; SET @E = @@ERROR SELECT @E IF @E > 0 ROLLBACK TRAN ELSE COMMIT TRAN

If displaying records that cannot be combined with internal join, https://dev.mysql.com/doc/refman/5.6/ja/join.html useSQLSELECT m_product.product_code, m_product.product_name, m_product.price, SUM(quantity) as total, SUM(quantity) * price as result FROM m_product left join t_sales on m_product.product_code = t_sales.product_code GROUP BY m_product.product_code; Resultproduct_codeproduct_namepriceTotal result Miso Ramen 100 10 1000 Salt Ramen 1000 0 0 Soy Sauce Ramen 1000nullnullDDL statement, insert statementcreate table m_product(product_code char(3), product_name varchar(20), price int); insert into m_product values ('001', '味噌ラーメン', 100); insert into m_product values ('002', '塩ラーメン', 1000); insert into m_product values ('003', '醤油ラーメン', 1000); create table t_sales(product_code char(3), quantity int); insert into t_sales values ('001', 10); insert into t_sales values ('002', 0); Since the table is difficult to respond in the image, it may be easier for the text to get the answer. http://sqlfiddle.com/#!9/c780a6/2

You could use cominication through https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage ExampleIn the main window, you subscribe to an event function onmessage<script> window.addEventListener('message', function(event) { // IMPORTANTE validar el origen if (event.origin !== "http://10.50.126.125") { return; } if (event.data.reload === true) { /* AQUI código para recargar / } }, false); </script> In the open window, by deleting a record saves in a variable if necessary (or not) reload the main window and, for example, at the time of closing/reloading the window (onbeforeunload) send a message with such information.<script> let reloadParent = true; // AQUI indcamos si es necesario recargar window.addEventListener('beforeunload', function () { // Enviamos un mensaje a la ventana padre window.opener.postMessage({ reload: reloadParent }, ''); }, false); </script>

SQL Server, and most database managers are managed with dates in ISO 8601 format, i.e. "aaaa-MM-dd" or "aaaaMMdd". Another thing is the format you use to show the data that can be different in each case, as it depends on the application you use, the type of culture configured on your PC, etc.In your case you must follow the pattern you show, although with a small detail, you must surround the date with simple quotation marks.SELECT campo1, campo2, fecha WHERE fecha > '2018-01-01';

When the name of the identifiers (ect column tables) have accented characters or other types use the exhausts, in the case of SQL SERVER are brackets ([])Change:SELECT descrição FROM ... To:SELECT [descrição] FROM ...

This is just a starting point and will likely need some tweaking. Essentially this will get you the 4 closest capture dates to your specified date (2 closest after and 2 closest before). You will need to add some logic to your outer select to pick which ones to use, but you will be doing a DATEDIFF on 4 fields instead of all of them. WITH CTE AS ( SELECT camera, MIN(r1.capture_date) as 'After', MAX(r2.capture_date) as 'Before' FROM rs_camera_pictures r1 INNER JOIN rs_camera_pictures r2 ON r1.location = r2.location AND r1.camera = r2.camera WHERE r1.capture_date > @date AND r2.capture_date < @date GROUP BY camera UNION ALL SELECT camera, MIN(r1.capture_date) as 'After', MAX(r2.capture_date) as 'Before' FROM rs_camera_pictures r1 INNER JOIN rs_camera_pictures r2 ON r1.location = r2.location AND r1.camera = r2.camera INNER JOIN CTE c ON r1.location = c.location AND r1.camera = c.camera WHERE r1.capture_date > c.[After] AND r2.capture_date < c.Before GROUP BY camera )

The request is in principle correct, but it needs to be corrected a little:Columns in the tables should not be labelled as reserved key words (c)date in this case)should be included GROUP BY Columns that are not aggregation in the sample sheetTotal, such request is working:select sum(t1.val) sumval, t2.SomeDt from t1, t2 where t1.Dt < t2.SomeDt group by t2.SomeDt If version 12.01 or later, the correlative request will be more effective:select sumval, t2.SomeDt from t2 cross apply ( select sum (t1.val) sumval from t1 where t1.Dt < t2.SomeDt) Both requests will produce the desired result: SUMVAL SOMEDT ---------- ------------------- 13 2020-02-28 00:00:00 21 2020-03-31 00:00:00 CTE with test data for examples above:with t1 (Id, Val, Dt) as ( select 1, 3, date'2020-03-10' from dual union all select 2, 9, date'2020-02-23' from dual union all select 3, 4, date'2020-02-25' from dual union all select 4, 5, date'2020-03-14' from dual ), t2 (SomeDt) as ( select date'2020-02-28' from dual union all select date'2020-03-31' from dual ) [здесь вставить сам запрос]

It's due to a problem with the formation of the chain, you've gone a quote.Try this:while ($registropoductos = $resproducto->fetch_array(MYSQLI_BOTH)) { $string = '<tr class="ta"> <td>' . $registropoductos['cod_inf'] . '</td>' . '<img src="' . $registropoductos["img_inf"] . '" width="50px" heigth="50px"><br>' . '<td>' . $registropoductos['img_inf'] . '</td>' . '<td>' . $registropoductos['pla_inf'] . '</td>' . '<td>' . $registropoductos['mot_inf'] . '</td>' . '<td>' . $registropoductos['est_inf'] . '</td>' . '<td> <a href="" data-toggle="modal" data-target="#exampleModal1" onclick="editar(' . $registropoductos['ced_per'] . ')">Editar /</a>&nbsp;<a href="eliminar.php?id=' . $registropoductos['ced_per'] .

I understand the form:Field('persona', 'reference personal') It's relatively new, at least for me that I don't use it some time ago. I remember that to achieve the same effect I did it this other way:db.define_table('personal', Field('persona', 'string'), format='%(persona)s' ) db.define_table('personal_registro', Field('dni', 'string'), Field('direccion','string'), Field('persona', db.personal), format='%(persona)s' ) It should be proved if this form is still working as in the current documentation I only see that they make use of reference.

You can in the select make an alias to each table and then just bring the required fields and not all (*) as you are doing now.SELECT clientes.nombre, clientes.apellido, sesiones.id, etc, etc FROM wp_ac_sesiones as sesiones LEFT JOIN wp_ac_clientes as clientes ON wp_ac_sesiones.id_usuario = wp_ac_clientes.id_usuario

select o.*, ov.price1 from oc_product o join (select product_id, min(price) as price1 from oc_product_option_value ov group by product_id) ov on o.product_id = ov.product_id order by ov.price1 There's no procedural extension at MySQL? It could be just a function to do that would return the minimum price of product_id.
