在SQL Server中,可以使用INSERT.. SELECT
语句将行插入到表中:
In SQL Server, it is possible to insert rows into a table with an INSERT.. SELECT
statement:
INSERT INTO Table (col1, col2, col3)
SELECT col1, col2, col3
FROM other_table
WHERE sql = 'cool'
是否也可以使用SELECT
更新表?我有一个包含值的临时表,并想使用这些值更新另一个表.也许是这样的:
Is it also possible to update a table with SELECT
? I have a temporary table containing the values and would like to update another table using those values. Perhaps something like this:
UPDATE Table SET col1, col2
SELECT col1, col2
FROM other_table
WHERE sql = 'cool'
WHERE Table.id = other_table.id
UPDATE
Table_A
SET
Table_A.col1 = Table_B.col1,
Table_A.col2 = Table_B.col2
FROM
Some_Table AS Table_A
INNER JOIN Other_Table AS Table_B
ON Table_A.id = Table_B.id
WHERE
Table_A.col3 = 'cool'
