Updating a table in sql
Then I created a new table named with schoolnew and similarly executed above actions on it.Then, to view inserted records in it, I execute SELECT [email protected] Ray what version of My SQL and what was your query, as this DOES infact function as stated. Col2)) UPDATE CTE SET Col1 = _Col1, Col2 = _Col2 statement on its own first to sanity check the results but it does requires you to alias the columns as above if they are named the same in source and target tables.Somewhat related, I often like to write my UPDATE queries as SELECT statements first so that I can see the data that will be updated before I execute. This also has the same limitation as the proprietary Thank you!As such the ON functions as your WHERE clause and the INNER JOIN skips records that are not found in the JOINed table.Adding a WHERE clause would limit the result set of the JOINed table as well.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.
(Of course this is not practical if I changed too many rows) Thank you for your interest in this question.
Account Number FROM Retrieve Account Number WHERE [Sales_Lead].[dbo].[Sales_Import]. Lead ID) I think there is no need for the inner join.
Vonki solution below works: UPDATE [Sales_Lead].[dbo].[Sales_Import] SET [Account Number] = Retrieve Account Number. As well as being standard SQL and thus more portable it also will raise an error in the event of there being multiple joined rows on the source side (and thus multiple possible different values to use in the update) rather than having the final result be undeterministic.
-- the join clause is whatever suits you DECLARE @tbl1 TABLE (id INT, col1 VARCHAR(10), col2 VARCHAR(10)) DECLARE @tbl2 TABLE (id INT, col1 VARCHAR(10), col2 VARCHAR(10)) INSERT @tbl1 SELECT 1, 'a', 'b' UNION SELECT 2, 'b', 'c' INSERT @tbl2 SELECT 1, '1', '2' UNION SELECT 2, '3', '4' UPDATE t SET t.col1 = a.col1 ,t.col2 = a.col2 FROM ( SELECT id, col1, col2 FROM @tbl2) a INNER JOIN @tbl1 t ON = SELECT * FROM @tbl1 SELECT * FROM @tbl2 drop table uno drop table dos create table uno ( uid int, col1 char(1), col2 char(2) ) create table dos ( did int, col1 char(1), col2 char(2), [sql] char(4) ) insert into uno(uid) values (1) insert into uno(uid) values (2) insert into dos values (1,'a','b',null) insert into dos values (2,'c','d','cool') select * from uno select * from dos The other way to update from select statement What is the difference to other answers? Keep in mind: A good answer will always have an explanation of what was done and why it was done in such a manner, not only for the OP but for future visitors to SO.
This answer turned up in the low quality review queue, presumably because you don't provide any explanation of the code. I am using a phone to reply this, no computer to try.
