我在调用 HANA 存储过程时遇到语法错误。在 Hana Studio 的 SQL 编辑器中它可以工作,但 Java 中 prepareCall 的语法必须不同。我认为这是包名称后的正斜杠,但不知道该怎么做。
是因为我在 Content 文件夹下创建了存储过程吗?它应该建在其他地方吗?
这是连接和调用。连接很好
Class.forName("com.sap.db.jdbc.Driver");
String url = "jdbc:sap://10.9.9.139:30015/GL1";
String user = "userid";
String password = "password";
cn = java.sql.DriverManager.getConnection(url, user, password);
if (cn == null) {
System.out.println("failed");
}
cs = cn.prepareCall("call '_SYS_BIC'.'myPackaged/ZMM_PR_MATERIALS_GET'"); <---- THROWS EXCEPTION BELOW
rs = cs.executeQuery();
while(rs.next()) {
System.out.println(rs.getString(0));
}
} catch(Exception e) {
e.printStackTrace();
}
// this WORKS FINE... i get a connection and get some records.
// rs = cn.createStatement().executeQuery("SELECT * FROM MYSCHEMA.ORDERS");
// int i = 0;
// while (rs.next()) {
// System.out.println(String.format("rec %2d: %s=%2s", ++i, "ORDER_ID", rs.getString("ORDER_ID")));
// }
