Specifies the temporary named result set or view, also known as common table expression (CTE), defined within the scope of the UPDATE statement.
The CTE result set is derived from a simple query and is referenced by UPDATE statement.
If that is more important to you than performance you might prefer this answer, especially if your update is a one off to correct some data. My server wont allow FROM to be used in an UPDATE statement. This may be a niche reason to perform an update (for example, mainly used in a procedure), or may be obvious to others, but it should also be stated that you can perform an update-select statement without using join (in case the tables you're updating between have no common field).
UPDATE Table SET Table.col1 = other_table.col1, Table.col2 = other_table.col2 FROM Table INNER JOIN other_table ON = other_WHERE Table.col1 ! = other_table.col2 OR ( other_table.col1 IS NOT NULL AND Table.col1 IS NULL ) OR ( other_table.col2 IS NOT NULL AND Table.col2 IS NULL ) ; WITH CTE AS (SELECT T1. So all the answers involving the FROM clause returned a syntax error. UPDATE suppliers SET supplier_name = (SELECT FROM customers WHERE customers.customer_id = suppliers.supplier_id) WHERE EXISTS (SELECT FROM customers WHERE customers.customer_id = suppliers.supplier_id); UPDATE Table SET Table.col1 = other_table.col1, Table.col2 = other_table.col2 --select Table.col1, other_table.col, Table.col2,other_table.col2, * FROM Table INNER JOIN other_table ON = other_UPDATE from SELECT with INNER JOIN in SQL Database Since there are too many replies of this post, which are most heavily up-voted, I thought I would provide my suggestion here too.
Account Number FROM Retrieve Account Number WHERE [Sales_Lead].[dbo].[Sales_Import]. UPDATE [Sales_Lead].[dbo].[Sales_Import] SET [Account Number] = Retrieve Account Number. See example below - it will only perform the update on 2 records despite linking on 3. Account Number Thank you for your interest in this question.
At first, I have created a table named with schoolold and inserted few records with respect to their column names and execute it.
The WHERE clause specifies which record(s) that should be updated.
The first syntactical form, called a searched update, updates the value of one or more columns for all rows of the table for which the WHERE clause evaluates to TRUE.
