The code fragment in Example 1.1 invokes SQLConnect and SQLDisconnect
to connect to and disconnect from the data store named FixedDs. The first
invocation of SQLConnect by any application causes the creation of the
FixedDs data store. Subsequent invocations of SQLConnect connect to the
existing data store.
在建立连接之前，FixedDs是客观存在的，它是已经存在的data store，为啥第一次连接时会创建呢FixedDs data store呢？
请高手们帮忙看下吧
