Oracle does not support joins in update queries - unlike other database, such as SQL Server (in which the query you are using would probably run just as it is). I would recommend a correlated subquery: update table_b b set second_value = (select emcb.aramestudio.ru_value from tablea a where emcb.aramestudio.ru_value = emcb.aramestudio.ru_value) where emcb.aramestudio.ru_value = 0. UPDATE table. SET col1 = constant_value1, col2 = constant_value2, colN = constant_valueN.
WHERE col = val. However, for different scenarios, this constant value usage type cannot be enough for us, and we need to use other tables’ data in order to update our table.

You can also batch them to avoid a round trip like this. BEGIN TRANSACTION; UPDATE Table1. SET emcb.aramestudio.rume = 'DR. XXXXXX' FROM Table1 T1, Table2 T2. WHERE emcb.aramestudio.ru = emcb.aramestudio.ru So if a CTE is created on one base table then it is possible to update the CTE, here the CTE is based on just the TblProfessor emcb.aramestudio.ru will actually update the underlying base table.
CTE based on two base tables. Now, let’s look at a scenario when a CTE is based on two base tables. Now, I have two tables TblProfessor and TblUniversity.
The sql table that gets updated in the above UPDATE exists in 3 different databases. The temp table stores an id value which will allow me to do a lookup to get the database name.

CREATE NONCLUSTERED INDEX IX_SOW_Number ON emcb.aramestudio.ru_Temp_Revenue(SOW_Number) INCLUDE. ;with cte as (select ID, Exp, Nation, row_number() over (order by Exp Desc) as RowNum from myTable) update cte set Nation = case RowNum % 2 = 1 then 1 else 2 end Premature optimization is the root of all evil in programming.

Two tables in our database. Each record in the people table has an id and a emcb.aramestudio.ru record in the scores table has a personId which is linked emcb.aramestudio.ru and a score.
If we wanted to retrieve data containing names next to scores, we could do this easily with a JOIN. SELECT emcb.aramestudio.ru, emcb.aramestudio.ru FROM people p JOIN scores s ON emcb.aramestudio.ru = emcb.aramestudio.ruId.
Hi @KML. I agree with @DavesTechTips's thought almost, if you want to update the base table using SQL view, you should add the base table as a data source within your PowerApps app. After you add the base table as a data source into your PowerApps app, you could use the Patch() function to update existing records or add new records into the base table based on the key columns within your SQL.

If Sql Server provide such nice. Challenges of Large Scale DML using T-SQL. Using T-SQL to insert, update, or delete large amounts of data from a table will results in some unexpected difficulties if you’ve never taken it to task.
Let’s say you have a table in which you want to delete millions of records. If the goal was to remove all then we could simply use TRUNCATE.

When you link to a SQL Server table or view, Access creates a linked table with the same name as the source object. If that name is already in use, Access will append "1" to the new linked table name — for example, Contacts1. (If Contacts1 is also already in use, Access will create Contacts2, and so on.).
