mysql_query 中 SELECT 之后的 INSERT 语句

Question

I'm trying to execute two SQL statements in one mysql_query.

$mySql = mysql_query("SELECT itemid, points FROM items WHERE id='1' UPDATE accounts SET userpoints = '1000'");

Is this possible? Thanks!

Answer 1

You can only execute one query in mysql_query (even if you seperate the queries with the semicolon terminator).

You have to call them seperately (although this guy has a method to automate that).

Answer 2

If you use mysqli you can use mysqli_multi_query()

Answer 3

I wouldn't try doing that since you won't be able to exploit the results from the different queries (returned values, mysql_insert_id(), ...)
