Updating mysql server
Compound assignment operator: = Add and assign -= Subtract and assign *= Multiply and assign /= Divide and assign %= Modulo and assign &= Bitwise AND and assign ^= Bitwise XOR and assign |= Bitwise OR and assign Returns updated data or expressions based on it as part of the UPDATE operation.
The OUTPUT clause is not supported in any DML statements that target remote tables or views.
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 command.
-- 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 Merge into product P1 using Product_Bak P2 on P1= P2.id; when matched then update set p1.[description] = p2.[description], p1= P2.
Specifies the temporary named result set or view, also known as common table expression (CTE), defined within the scope of the UPDATE statement.
The search condition can also be the condition upon which a join is based. The Microsoft SQL Server ODBC driver and OLE DB Provider for SQL Server automatically set ANSI_PADDING ON for each connection.
Specifies the condition to be met for the rows to be updated. If ANSI_PADDING is set to OFF, all trailing spaces are removed from data inserted into varchar and nvarchar columns, except in strings that contain only spaces. If ANSI_PADDING is set to ON, trailing spaces are inserted. Col2 AS _Col2 FROM T1 JOIN T2 ON T1= T2/*Where clause added to exclude rows that are the same in both tables Handles NULL values correctly*/ WHERE EXISTS(SELECT T1. 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. This also has the same limitation as the proprietary 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).If 'N' is not specified, SQL Server converts the string to the code page that corresponds to the default collation of the database or column.Any characters not found in this code page are lost.
