从返回多个结果集的存储过程插入临时表 [英] Insert Into temp table from a stored procedure that returns multiple result sets

问题描述

考虑下面的sql

一个名为 myProc 的存储过程，它返回两个结果集.结果集 1 返回 column1、column2.结果集 2 返回第 3 列、第 4 列、第 5 列.

A stored proc called myProc which returns two result sets. Result set 1 returns column1, column2. Result set 2 returns column 3, column 4, column 5.

由于临时表仅定义了 2 个 int 列，因此以下 sql 将失败.

The following sql will fail since the temp table only has defined 2 int columns.

Create Table #temp1(
Column1 int,
Column2 int)

insert into #temp1 exec myProc

我的问题是是否可以只将第一个结果集插入 #temp1 中?

My question is is it possible to just insert the first result set into #temp1?

推荐答案

旧帖子，但我遇到了同样的问题，虽然上面提到的答案有点相关，但 OP 的问题是关于返回多个集合的 SP.除了重写 SP 以将其拆分为更小的 SP 之外，我能找到的唯一解决方案是编写一个 SQL CLR 过程，该过程执行 SP 并仅返回所需的结果集.该过程获取所需结果集的索引，执行 SqlCommand 以运行初始 T-SQL SP，然后循环访问 SqlDataReader 结果直到它找到所需的结果集并返回相应的记录.以下代码是 SQL CLR 过程的一部分:

Old post, but I faced the same problem and although the answers mentioned above are a bit related, the OP's question is about SP that returns multiple sets. The only solution I could find, apart from rewriting the SP to split it into smaller SPs, was to write a SQL CLR procedure that executes the SP and returns only the required result set. The procedure gets the index of the required result set, executes a SqlCommand to run the intial T-SQL SP, then loops through a SqlDataReader results until it finds the desired result set and returns the corresponding records. The following code is part of the SQL CLR procedure:

SqlDataReader rdr = command.ExecuteReader();
int index = 0;
bool bContinue = true;
while (index < resultSetIndex.Value)
{
    if (!rdr.NextResult())
    {
        bContinue = false;
        break;
    }
    index++;
}
if (!bContinue)
    throw new Exception("Unable to read result sets.");

.......

List<SqlMetaData> metadataList = new List<SqlMetaData>();
for (int i = 0; i < rdr.FieldCount; i++)
{
    string dbTypeName = rdr.GetDataTypeName(i);
    SqlMetaData metadata;
    if (dbTypeName.ToLower().Contains("char"))
        metadata = new SqlMetaData(rdr.GetName(i), (SqlDbType)Enum.Parse(typeof(SqlDbType), dbTypeName, true), 50);
    else
        metadata = new SqlMetaData(rdr.GetName(i), (SqlDbType)Enum.Parse(typeof(SqlDbType), dbTypeName, true));
    metadataList.Add(metadata);
}
SqlDataRecord record = new SqlDataRecord(metadataList.ToArray());
object[] values = new object[rdr.FieldCount];
if (rdr.HasRows)
{
    SqlContext.Pipe.SendResultsStart(record);
    while (rdr.Read())
    {
        rdr.GetValues(values);
        record.SetValues(values);
        SqlContext.Pipe.SendResultsRow(record);
    }
    SqlContext.Pipe.SendResultsEnd();
}
