Ms sql updating one table from another

In the following UPDATE statement, I modify only the rows that have a Territory Name value of United Kingdom: As you can see, I specify in the SET clause that the Territory Name value should be changed to UK.

For example, in the following UPDATE statement, I modify the row with the Full Name value of Stephen Jiang: As you can see, the WHERE clause limits the rows being updated to those that include the Full Name value of Stephen Jiang (again, only one row).The following example modifies the data in the Sales Staff table by changing the value of the Sales Quota column to 250000.Notice that I first specify the UPDATE keyword, followed by the name of the table-Sales Staff.

Hi All This sort of leads on from another post of mine: COuld anyone advise me on what the SQL syntax would be to update 1 row with another rows data within the same table. UPDATE TABLE1 (COL1, COL2, COL3) WHERE COL1 = 7 With the data from TABLE1 (COL1, COL2, COL3) WHERE COL1 = 4 Many thanks!In addition, the statement can include a WHERE clause, which determines what rows to modify, or a FROM clause, which identifies tables or views that provide values for the expressions defined in the SET clause.

In this article, I discuss how to use the UPDATE statement to modify data.

I also provide examples that demonstrate how the various clauses work.

I created the examples in the Adventure Works2008 database on a local instance of SQL Server 2008.

However, you’ll often want to update only specific rows. To limit the rows that are updated when you issue an UPDATE statement, add a WHERE clause after the SET clause.

The WHERE clause specifies the search conditions that define which rows in the target table should be updated.

When specifying the table or view, be sure to qualify the name with the schema, database, and server names, as necessary.
