I'm working with some complex Stored Procs that have multiple queries occurring, creating and dropping temp tables, etc. Looking through the SP, I can eventually discern what fields are returned by the Stored Proc, but it's painful and time-intensive. e.g, an SP might look like this:
ALTER procedure [dbo].[sp_duckbilled_platypi]
@BegDate varchar(10),
@EndDate varchar(10),
@Platypus varchar(max),
@Duckbill varchar(max)
as

Given such an SP, is there a way to query said SP to get a list of the fields that will be available to me after calling the SP? IOW, to know which fields I can reference when I do something like this:
DataTable dtPlatypusResults = [call the SP]
foreach (DataRow summary in dtPlatypusResults.Rows)
{
var ps = new PlatypusSummary
{
. . .
...can I get a list of the field values the SP returns which I can reference like so:
var ps = new PlatypusSummary
{
platypus = Convert.ToDouble(summary["poisonToeLength"]),
. . .
?
答案 0 :(得分：1)
在DataTable列中，可以通过遍历列并获取名称或使用LINQ来列出名称。
例如
string[] columnNames = dtPlatypusResults.Columns.Cast<DataColumn>()
.Select(x => x.ColumnName)
.ToArray();
