我有一个问题，我使用jdbcTemplate exec一个Sybase存储过程返回多个ResultSet，我怎么能得到所有的resultSet？

我告诉你你说的话并尝试其他的东西。我告诉你代码打击：
ResultSet rs = null;
int updateCount = -1;
int index = 1;
do {
updateCount = cs.getUpdateCount();
if (updateCount != -1) { // it means it's a updateConut
cs.getMoreResults();
System.out.println("updateCount:" + updateCount);
continue;
}
rs = cs.getResultSet();
System.out.println(rs);
if (rs != null) {// it means updateCount == -1 and returns a resultSet
if (1 == index) {
index++ ;
if(rs.next()) {
int errCode = rs.getInt(1);
String errMsg = rs.getString(2);
System.out.println("errCode:" + errCode + " errMsg:" + errMsg);
if (!(Constants.PROC_ERRORCODE_SUCC == errCode)) {
logger.error("call sp errror:" + errMsg);
}
}
} else if (2 == index) {
index++ ;
rs = cs.getResultSet();
while (rs.next()) {
//proc resultSet
}
} else if (3 == index) {
index++ ;
rs = cs.getResultSet();
// proc resultSet
}
} else {
break;
}
cs.getMoreResults();
continue;
}
// it means updateCount == -1 && rs == null nothing left to return
} while (!(updateCount == -1 && rs == null));
这是调试结果
updateCount:1
updateCount:1
updateCount:1
updateCount:0
updateCount:0
updateCount:1
updateCount:1
updateCount:1
updateCount:1
org.apache.commons.dbcp.DelegatingResultSet@bd4e3c
errCode:0 errMsg:
updateCount:1
updateCount:1
updateCount:1
null
这是正确的代码
ResultSet rs = null;
int updateCount = -1;
int index = 1;
do {
updateCount = cs.getUpdateCount();
if (updateCount != -1) {// it means it returns a updateCount
cs.getMoreResults();
continue;
}
rs = cs.getResultSet();
if (rs != null) {// it means it returns a ResultSet
if (1 == index) {
index++;
if(rs.next()) {
int errCode = rs.getInt(1);
String errMsg = rs.getString(2);
// System.out.println("errCode:" + errCode + " errMsg:" + errMsg);
if (!(Constants.PROC_ERRORCODE_SUCC == errCode)) {
logger.error("call sp execute error:" + errMsg);
}
}
rs.close(); // it should call close() here
} else if (2 == index) {
index++;
while (rs.next()) {
//proc the second resultSet
}
rs.close(); // it should call close() here
} else if (3 == index) {
index++;
while (rs.next()) {
//proc the second resultSet
}
rs.close(); // it should call close() here
} else {
break;
}
cs.getMoreResults();
continue;
}
} while (!(updateCount == -1 && rs == null)); //nothing to return
答案 0 :(得分：1)
你一直在循环中调用getMoreResults
CallableStatement cstmt;
ResultSet rs;
int i;
...
cstmt.execute(); // Call the stored procedure
while (cstmt.getMoreResults()){ // If we have more Results
rs = cstmt.getResultSet(); // Get the result set
while (rs.next()) {
i = rs.getInt(1);
System.out.println("Value from result set = " + i);
}
}
rs.close();
cstmt.close();
对于存储过程，看起来总是返回三个结果集
代码应该让你接近，但是如果你想调试它，你可以按照我给你的方式进行循环，并在循环内部调用ResultSetMetaData rsmd = rs.getMetaData（）;并且rsmd对象将告诉你关于当前resultset的几乎所有内容，这样你就可以真实地了解返回的内容。
CallableStatement cstmt;
ResultSet rs;
int i;
...
cstmt.execute(); // Call the stored procedure
// select @errcode,@errmsg
rs = cstmt.getResultSet(); // Get the result set
while (rs.next()) {
// Process the resultset
}
rs.close();
// select op_type, xyqrid, dh, yhdmc, type, qsrq, jzrq,qssj, jzsj, jsfs, oano, description, oprrq, oprsj from #head
rs = cstmt.getResultSet(); // Get the result set
while (rs.next()) {
// Process the resultset
}
rs.close();
// select op_type,xyqrid,dh,gdsid,orgid,qdid,tjlb,pp,gys,fmid,yhed,yhsl,unit from #detail
rs = cstmt.getResultSet(); // Get the result set
while (rs.next()) {
// Process the resultset
}
rs.close();
cstmt.close();
