我有一个postgres数据配置文件。
<dataConfig>
<dataSource driver=”org.postgresql.Driver” url=”jdbc:postgresql://127.0.0.1:5432/mydb” user=”user” password=”pw” />
...
</dataConfig>
但是当我运行它时，它显示错误
Data Config problem: Open quote is expected for attribute "driver" associated with an element type "dataSource".
这是什么问题。我弄错了驾驶员信息吗？

"Types can be of course from Data Dictionary, here we define types for demonstaration purpose only.
TYPES:
BEGIN OF ty_connection,
connid TYPE s_conn_id,
END OF ty_connection.
TYPES:
BEGIN OF ty_cat,
cat TYPE s_conn_id,
END OF ty_cat.
TYPES ty_connections TYPE STANDARD TABLE OF ty_connection WITH NON-UNIQUE KEY connid.
DATA:
connections_structured2 TYPE ty_connections,
connections_unstructured TYPE STANDARD TABLE OF s_conn_id,
cats_structured TYPE STANDARD TABLE OF ty_cat WITH NON-UNIQUE KEY cat.
SELECT * FROM sflight INTO TABLE @DATA(flights) UP TO 10 ROWS.
DATA(connections_structured) = CORRESPONDING ty_connections( flights ).
connections_structured2 = CORRESPONDING #( flights ).
"FOR can be combined with REDUCE, WHERE, FILTER and INIT, to get out more from BI Queries
DATA(connections_structured3) = VALUE ty_connections( FOR flight IN flights ( connid = flight-connid ) ).
"Of course you can cut out 2 of 3 columns also, here we cut only one out
connections_unstructured = VALUE #( FOR flight IN flights ( flight-connid ) ).
"Move column to other internal table with different field name

和”是不同类型的引号（请参阅不同的演示文稿）。在XML文件（以及大多数/所有编程上下文）中，只有"是有效的双引号。
