我点击一个按钮，执行如下代码，为什么能点击多次，可以多次select into 临时表 吗？
在查询分析器里只能执行一次select into 临时表。为什么在这里能执行多次？

SqlCommand cmd3 = new SqlCommand("select Field_Value from I_defaultvalue where Table_Name='SYSTEM' and  Table_Field='CUT_CUSTOM_ORDER_RECORD'", con);
            string Field_Value=cmd3.ExecuteScalar().ToString();
            if (Field_Value=="0") 

            { 
                SqlCommand cmd4 = new SqlCommand("select WRPROD,WRTOOL into tbb  from I_CustomOrder group by  WRPROD,WRTOOL", con);    
                cmd3.ExecuteReader();
            }
            else
            {
            
                SqlCommand cmd5 = new SqlCommand("select top Field_Value WRPROD,WRTOOL into tbb  from I_CustomOrder group by  WRPROD,WRTOOL", con);    
                cmd3.ExecuteReader();
            }
