我的数据库中有一个包含透视表的存储过程。
create or replace procedure example1(var1 OUT SYS_REFCURSOR)
is
DATE_FROM date;
DATE_TO date;
begin
DATE_TO := sysdate;
DATE_FROM := sysdate -10;
open var1 for
select *
from
( select m as MONTHS, s as SERIES, SUM(t) as N
from tablename
WHERE dateletter BETWEEN date_from AND date_to
group by m, s
ORDER BY m
)
PIVOT XML (SUM(N) as TOTALSUM for SERIES in (select distinct s from tablename where dateletter between date_from and date_to group by s));
END example1;
这可以正常工作,并显示类似这样的内容
Month SERIES_XML
2 oracle.jdbc.driver.ORACLESQLXML@d77ww5
现在在我的java类中
CallableStatement acs1;
acs1 = generalcon.con.prepareCall(getCursor);
acs1.registerOutParameter(1, OracleTypes.CURSOR);
acs1.executeQuery();
ars1 = (ResultSet) acs1.getObject(1);
while(ars1.next())
{
String ser = ars1.getString(2);
xmlst = xmlst + ser;
}
但是,
ars1.getString(2)
返回一个空值,其中1是ColumnIndex我尝试使用
ars1.getString('SERIES_XML')
,但结果相同。您能帮我得到正确的列名和相应的值吗
最佳答案
我不知道您是否仍然遇到此问题,最近我遇到了同样的事情,这可以帮助我获取ResultSet中的所有列:
ResultSetMetaData rsmd = result.getMetaData();
int columnCount = rsmd.getColumnCount();
// The column count starts from 1
for (int j = 1; j <= columnCount; j++) {
System.out.println(rsmd.getColumnName(j) + " - " + rsmd.getColumnType(j) + " - " + rsmd.getColumnTypeName(j));
}
再见!
