I have in the database:
ALTER PROCEDURE [dbo].[uspConsumeEnrollments]
(--#File NVARCHAR(300),
#XML XML,
#FamilySent INT = 0 OUTPUT)
AS
BEGIN
SELECT #FamilySent = 755;
Here I am trying to download data:
public int Create(FamilyModel model)
{
try
{
var XML = model.GetEnrolmentFromModel().Serialize();
var RV = -99;
var familySent = 0;
using (var imisContext = new ImisDB())
{
var returnParameter = new SqlParameter("#RV", SqlDbType.Int);
returnParameter.Direction = ParameterDirection.Output;
var xmlParameter = new SqlParameter("#XML", XML);
xmlParameter.DbType = DbType.Xml;
var familySentParameter = new SqlParameter("#FamilySent", SqlDbType.Int);
familySentParameter.Value = 0;
familySentParameter.Direction = ParameterDirection.Output;
var sql = "exec #RV = uspConsumeEnrollments #XML, #FamilySent";
SqlParameter[] myParams = { returnParameter, xmlParameter, familySentParameter };
var result = imisContext.Database.ExecuteSqlCommand(sql, myParams);
RV = (int)returnParameter.Value;
Debug.WriteLine("RV: " + RV);
try
{
familySent = (int)familySentParameter.Value;
}
catch { }
Debug.WriteLine("familySent: " + familySent);
}
return RV;
}
catch (SqlException e)
{
}
}
The reference to the procedure works because I get the RV
I have a problem with FamilySent: I do not get any value.
In the above example I have #FamilySent = 755;
This should be returned and displayed in
Debug.WriteLine("familySent:" + familySent);
but it does not work.
Please try this out :
Modified version of your stored procedure :
ALTER PROCEDURE [dbo].[uspConsumeEnrollments](

)
AS
BEGIN
SELECT #FamilySent = 755 as FamilySent;
C# code :
public int Create(FamilyModel model)
{
try
{
var XML = model.GetEnrolmentFromModel().Serialize();
var RV = -99;
var familySent = 0;
using (SqlConnection cnx = new SqlConnection(connexionString))
using (SqlCommand cmd = new SqlCommand("[dbo].[uspConsumeEnrollments]", cnx))
{
cmd.CommandType = CommandType.StoredProcedure;
var xmlParameter = new SqlParameter("#XML", XML);
xmlParameter.DbType = DbType.Xml;
cmd.Parameters.Add(xmlParameter);
var familySentParameter = new SqlParameter("#FamilySent", SqlDbType.Int);
familySentParameter.Value = 0;
familySentParameter.Direction = ParameterDirection.Output;
cmd.Parameters.Add(familySentParameter);
cnx.Open();
List<string[]> res = new List<string[]>();
using (SqlDataReader reader = cmd.ExecuteReader())
{

// then here get all of your data you need
if(res.Count > 0){

break;

I have a string array which consists of identifiers. I want to get some values from SQL using these identifiers . Is there a way of adding them with a string value to SqlCommand parameters?
I want to create a query like:
select CaseList from MasterReportData where Id = 1 OR Id = 2 OR Id = 3
This is my C# code:
public static List<string> GetCaseList(string[] masterIdList)
{
try
{
string query = " select CaseList from MasterReportData where #masterId";
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(query, conn);
cmd.Parameters.AddWithValue("masterId", ***);
conn.Open();
using (SqlDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
list.Add(reader[0].ToString());
}
}
conn.Close();
}
catch (Exception e)
{
var err= 0;
}
return list;
}
There are many different ways you can go about doing this but I prefer to create a temp table of possible values. That way you can do something like
select CaseList from MasterReportData where Id IN(select Id from tempTable)
The best approach (with sql optimization) would be:
Create your Type:
CREATE TYPE dbo.IntTTV AS TABLE
( Id int )
Your Ids:
var ids = new List<int>
{
1,
2,
3,
}
Create a schema:
var tableSchema = new List<SqlMetaData>(1)
{
new SqlMetaData("Id", SqlDbType.Int) // I think it's Int
}.ToArray();
Create the table in C#
var table = ids
.Select(i =>
{
var row = new SqlDataRecord(tableSchema);
row.SetInt32(0, i);
return row;
})
.ToList();
Create the SQL Parameter
var parameter = new SqlParameter();
parameter.SqlDbType = SqlDbType.Structured;
parameter.ParameterName = "#Ids";
parameter.Value = table;
parameter.TypeName = "dbo.IntTTV";
var parameters = new SqlParameter[1]
{
parameter
};
Slightly change your query (this is just an example:)
string query = "select mrd.CaseList from MasterReportData mrd"
+ " inner join #ids i on mrd.Id = i.id";
public static List<string> GetCaseList(string[] masterIdList)
{
List<string> list = new List<string>();
try
{
string query = "select CaseList from MasterReportData where ";
using (SqlConnection conn = new SqlConnection(connString))
{
int i = 0;
SqlCommand cmd = new SqlCommand(query, conn);
for(i = 0; i < masterIdList.Length; i++)
{
var parm = "#ID" + i;
cmd.Parameters.Add(new SqlParameter(parm, masterIdList[i]));
query += (i > 0 ? " OR " : "") + " Id = " + parm;
}
cmd.CommandText = query;
//cmd.Parameters.AddWithValue("masterId", ***);
conn.Open();
using (SqlDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
list.Add(reader[0].ToString());
}
}
}
}
catch (Exception e)
{
e.ToString();
}
return list;
}

I've read all previous thread on this topic but couldn't find appropriate solution yet.
SqlCommand objCommand = new SqlCommand();
you can recreate this object then it will work.
I got this answer.
You have two fields:
Is Deleted
Is Primarry
You have to passed the boolean that may have true/false.
Try passing 1 for true and 0 for false.
This should do the trick

double[] paramValue;
string[] timeStamp;
var client = new WebServiceSample.WebService1SoapClient();
paramValue = client.GetWeatherItemData(paramName, dtFrom, dtTo).Value.ToArray();
timeStamp = client.GetWeatherItemData(paramName, dtFrom, dtTo).TimeStamp.ToArray();
This seems to work fine. But i have annother method that returns an array of the same struct:
public struct GetWeatherItemDataStruct
{
//public DateTime[] TimeStamp;
public double[] Value;
public string[] TimeStamp;
}
[WebMethod]
public GetWeatherItemDataStruct[] GetSelectedWeatherItemsData(string[] parameterName, string fromTime, string toTime)
{
int numbeOfParameters = parameterName.Length;
GetWeatherItemDataStruct[] getSelectedItemsStructObj = new GetWeatherItemDataStruct[numbeOfParameters];
SqlConnection conn = null;
SqlDataReader rdr = null;
int prameterID = 0;
int tblSize = 0;
double[] result;
int i = 0;
int counter = 0;
for (counter = 0; counter < numbeOfParameters; numbeOfParameters++)
{
prameterID = GetParameterID(parameterName[counter]);
tblSize = GetTableSize(parameterName[counter], fromTime, toTime, prameterID);
result = new double[tblSize];
string[] tStamp = new string[tblSize];
String source = "Data Source=MASTER-PC\\SQLEXPRESS;Initial Catalog=WeatherDatabase;Integrated Security=True";
try
{
using (conn = new SqlConnection(source))// create and open a connection object
{
// 1. create a command object identifying
// the stored procedure
SqlCommand cmd = new SqlCommand("GetWeatherItemData", conn);
// 2. set the command object so it knows
// to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;
// 3. add parameter to command, which
// will be passed to the stored procedure
//cmd.Parameters.Add(new SqlParameter("#WeatherParameterID", "1"));
cmd.Parameters.Add("#WeatherParameter", SqlDbType.VarChar).Value = parameterName;
cmd.Parameters.Add("#FromTimeStamp", SqlDbType.VarChar).Value = fromTime;
cmd.Parameters.Add("#ToTimeStamp", SqlDbType.VarChar).Value = toTime;
conn.Open();
// execute the command
rdr = cmd.ExecuteReader();
while (rdr.Read())
{
result[i] = (double)rdr["MeasurementValue"];
tStamp[i] = rdr["Recieved"].ToString();
i++;
}
getSelectedItemsStructObj[counter].Value = result;
getSelectedItemsStructObj[counter].TimeStamp = tStamp;
}
}
catch (SqlException e)
{
//Log exception
//Display Error message
}
}
return getSelectedItemsStructObj;
}
Here im stuck. How do i read the tables for each object?
Based on the comments above.
To get data from a struct inside an array, you retrieve it just like you were setting it.
myArrayOfStruct[0].myStructProperty
If it's an array IN the struct, it's just:
myArrayOfStruct[0].myArrayProperty[0]
If you wanted to loop through all structures in the array and all of the items in an array property, you'd next two loops:
for (int i = 0; i < myArrayOfStruct.length; i++){
for (int j = 0; j < myArrayProperty.length; j++){
myData = myArrayOfStruct[i].myArrayProperty[j];
// do something with the data
}
}
Basically, myArrayOfStruct[0].myProperty is the same as accessing it like this:
MyStruct myStruct = myArrayOfStruct[0];
myStruct.myProperty
Does this answer your question? You set it correctly above. You retrieve it in a similar fashion.
