mssql_fetch_array是否执行与数据库服务器的连接？

Question

I am developing a script that connects to a SQL Server database to fetch data and store it in a MySQL one.

One of the problems I am having is that the SQL Server is not prepared to handle heavy traffic.

At this point, I am executing a query that returns 4385 results (mssql_num_rows), and I want to loop over them. My question is if every mssql_fetch_array call connects to the database, or if the result of mssql_query is stored in memory.

I am not in the position of testing it to see if the server crashes, so that's why I have to ask before doing anything.

Thank you in advance.

Answer 1

mssql_fetch_array does not connect to the database each time. It will just loop through the record fetched by mssql_query().

Answer 2

从数据库检索到的所有数据都存储在一个变量中，因此您的循环将不会连接到数据库！
