JdbcTemplate multiple result sets
I managed to get a Set<ResultSet>
using this code,
private Set<ResultSet> executeProcedure(final String sql)
{
return jdbc.execute(new CallableStatementCreator() {
@Override
public CallableStatement createCallableStatement(Connection con) throws SQLException
{
return con.prepareCall(sql);
}
}, new CallableStatementCallback<Set<ResultSet>>() {
@Override
public Set<ResultSet> doInCallableStatement(CallableStatement cs) throws SQLException
{
Set<ResultSet> results = new HashSet<>();
boolean resultsAvailable = cs.execute();
while (resultsAvailable)
{
results.add(cs.getResultSet());
resultsAvailable = cs.getMoreResults();
}
return results;
}
});
}
Just going to look at translating a ResultSet
into List<Map<String, Object>>
.
You can use the resultSet.getMetaData() method to work out what columns are in the data:
ResultSetMetaData meta = resultSet.getMetaData();
int colcount = meta.getColumnCount();
for (int i = 1; i <= colcount; i++)
{
String name = meta.getColumnLabel(i); // This is the name of the column
int type = meta.getColumnType(i); // from java.sql.Types
// Maybe add to a Map,List, etc...
}
You can then do as the other commentors have mentioned do a loop through the ResultSet pulling out the data you need:
while (resultSet.hasNext())
{
resultSet.next();
// Find the columns you want to extract (via the above method maybe) and add to your row.
}
