Date Format: No overload for method "ToString" takes 1 arguments

I stay with that error when I'm trying to format a date in my code:
Cmd.CommandText = #"
DECLARE #command varchar(5000);
DECLARE #RestoreList TABLE(DB_name VARCHAR(100), RS_name VARCHAR(100), RS_DateFinExercice DATE, RS_IsClosed VARCHAR(50));
SELECT #command = 'IF ''?'' IN (SELECT name FROM sys.databases WHERE HAS_DBACCESS(name) = 1 AND CASE WHEN state_desc = ''ONLINE'' THEN OBJECT_ID( QUOTENAME( name ) + ''.[dbo].[P_DOSSIER]'',''U'' ) END IS NOT NULL) BEGIN USE [?] SELECT DB_name = CAST(DB_NAME() AS VARCHAR(100)), RS_name = CAST(a.D_RaisonSoc AS VARCHAR(100)), RS_DateFinExercice = CAST((SELECT Max(v) FROM (VALUES (a.[D_FinExo01]), (a.[D_FinExo02]), (a.[D_FinExo03]),(a.[D_FinExo04]),(a.[D_FinExo05])) AS value(v)) AS DATE), RS_IsClosed = CAST((SELECT CASE WHEN (SUM (CASE WHEN JM_Cloture !=2 THEN 1 ELSE 0 END)>0) THEN '''' ELSE ''arc'' END FROM F_JMOUV) AS VARCHAR(50)) FROM [dbo].[P_DOSSIER] a INNER JOIN F_JMOUV b ON DB_name() = DB_NAME() GROUP BY D_RaisonSoc, D_FinExo01, D_FinExo02, D_FinExo03, D_FinExo04, D_FinExo05 HAVING COUNT(*) > 1 END'
INSERT INTO #RestoreList EXEC sp_MSforeachdb #command;
SELECT * FROM #RestoreList ORDER BY DB_name;";
SqlDataReader dr = Cmd.ExecuteReader();
List<DBtoRestore> dgUIDcollection = new List<DBtoRestore>();
if (dr.HasRows)
{
while (dr.Read())
{
DBtoRestore currentdgUID = new DBtoRestore
{
CUID_dbname = dr["DB_name"].ToString(),
CUID_RaisonSoc = dr["RS_name"].ToString(),
CUID_DateFinExercice = dr["RS_DateFinExercice"].ToString(),
CUID_IsClosed = dr["RS_IsClosed"].ToString()
};
dgUIDcollection.Add(currentdgUID);
}
}
dgDBtoRestore.ItemsSource = dgUIDcollection;
Cnx.Close();
The problem is on this line of code:
CUID_DateFinExercice = dr["RS_DateFinExercice"].ToString()
For now, my datagrid report date like 01/01/2020 00:00:00. In SQL, I have 01-01-2020 style.
I want to have the same style in my datagrid.
I have try something like ToString("dd-MM-yyyy") but it's in that context I've received the error.
Any idea to help me?

Convert to a DateTime and then call ToString on it:
Convert.ToDateTime(dr["RS_DateFinExercice"]).ToString("dd-MM-yyyy")

Solution :
CUID_DateFinExercice = ((DateTime)dr["RS_DateFinExercice"]).ToString("dd-MM-yyyy"),

Calling stored procedure error on return value error data type nvarchar(max) to int

I calling a stored procedure and it has an int return value. However there is an error on returning the value back to my back end.
public async Task<string> CreatePortfolio(Portfolio portfolio)
{
string statusMessage;
using (SqlConnection conn = new SqlConnection(Connection))
{
SqlParameter returnValue = new SqlParameter(); //Holds the bit that determines if insert was successful or not
SqlCommand command;
command = new SqlCommand();
command.Connection = conn;
conn.Open();
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "USP_Add_Portfolio";
command.Parameters.AddWithValue("#portfolioName", portfolio.PortfolioName);
command.Parameters.AddWithValue("#description", portfolio.Description);
command.Parameters.AddWithValue("#createID", portfolio.CreateID);
command.Parameters.AddWithValue("#updateID", portfolio.UpdateID);

go
The stored procedure finishes and it adds the new record but it errors on
int i = await command.ExecuteNonQueryAsync().ConfigureAwait(false);
Error:
expecting an int but gets nvarchar

ExecuteNonQuery (not worrying about the async for the moment...) returns the number of rows affected for UPDATE, INSERT, DELETE, and -1 otherwise. It does NOT return information directly from the stored procedure.
In your case above, I think you should call the "await" without the "int i =" and not worry about the return value from the ExecuteNonQueryAsync call. Instead, after the value, look at the value in returnValue.Value, which would be the value of the "return" parameter. It is an object, so verify the type or use Convert.ToInt32().

This doesn't look correct because SqlDbType.NVarChar is an enumeration value:
command.Parameters.AddWithValue("#statusMessage", SqlDbType.NVarChar).Direction = ParameterDirection.Output;
What happens if you use this instead:
command.Parameters.Add(new SqlParameter("#statusMessage", SqlDbType.NVarChar, -1)).Direction = ParameterDirection.Output;

-I really don't know what's happening here since i'm just a newbie but when I changed it to "string", it works well.
-Remaining issue is when I'm setting a session.

Building dynamic sql query with between and order by key word

I have a situation where parameter to my sql query would be dynamic.if parameter is null i don't want to add it to the query,I have tried some thing(never worked)..and it look like stoopid to me now
ds = SqlHelper.ExecuteDataset(GlobalSettings.DbDSN, CommandType.Text, "SELECT TOP 1000 [ID],[Project],[Owner],[Consultant],[Contractor],[Value],[Level1],[Level2] ,[Status] ,[Category] ,[Country],[CreatedDate],[CreatedByID],[CreatedByName] FROM [tbl_Projects] where"+if(!string.IsNullOrEmpty(paraCategory)){ "[Category] = #Category and"}+"+ Country =#country and "+if(!string.IsNullOrEmpty(paraCategory)){ " value between #val1 and #val2"}+" order by CreatedDate asc",
new SqlParameter("#Category", paraCategory),
new SqlParameter("#Country", paraCountry),
new SqlParameter("#val1", paraValue1),
new SqlParameter("#val2", paraValue2));
I have checked Building dynamic sql also
here
But it is not usefull where I need to put like and between key words..can any one give me a hand on this?

Just to give you an idea, I would do something like this:
var sql as new StringBuilder();
sql.Append("SELECT ... all your columns ... FROM yourTable");
var parameters as new List(Of SqlParameter);
if (!string.IsNullOrEmpty(paraCategory)
{
sql.Append("[Category]=#Category,");
parameters.AddWithvalue("#Category", paraCategory);
}
sql.Length -= 1
//...your other parameters...
sql.Append("ORDER BY CreatedDate");
And then pass it all to your SqlHelper:
ds = SqlHelper.ExecuteDataset(GlobalSettings.DbDSN, CommandType.Text, sql.ToString(), parameters);
Also note that the above code is not really defensive. So for example if no parameter is delivered it will fail. And since I don't know the SqlHelper-Class, you might need to have something else than a List(Of SqlParameter).

Change SqlHelper.ExecuteDatasetso that it takes a delegate to call the specific code you want:
class SqlHelper
{
public delegate void SqlCommandDelegate(SqlCommand command);
public Dataset ExecuteDataset(string dsn,
CommandType commandType,
SqlCommandDelegate specificPreparations)
{
Dataset results;
using (SqlConnection conn = new SqlConnection())
{
conn.ConnectionString = dsn;
using (SqlCommand command = conn.CreateCommand())
{
command.CommandType = commandType;
connection.Open();
specificPreparations(command);
SqlDataReader reader = command.ExecuteReader();
results.Load(reader);
}
}
return results;
}
}
Then to call it:
ds = SqlHelper.ExecuteDataset(GlobalSettings.DbDSN,
CommandType.Text,
delegate(SqlCommand command)
{
command.CommandText = "SELECT BLAH FROM BLAH";
foreach (var myParameter in myParameterList)
{
SqlParameter p = new SqlParameter();
// Construct p
command.Paramters.Add(p)
}
// Anything else you want to do to the command
});
}

you can do this using a SP
CREATE PROCEDURE MyDynamicSP(#Condition1 as varchar(100),Condition2 as varchar(100),Condition3 as varchar(100))
AS
SET NOCOUNT ON
DECLARE #STRSQL VARCHAR(1000)
SET #STRSQL = 'SELECT * FROM MyTable WHERE '
IF NOT #Condition1 IS NULL
#STRSQL = #STRSQL + ' ' + #Condition1
IF NOT #Condition2 IS NULL
#STRSQL = #STRSQL + ' ' + #Condition2
IF NOT #Condition3 IS NULL
#STRSQL = #STRSQL + ' ' + #Condition3
EXEC sp_executesql #STRSQL
SET NOCOUNT OFF

You can do the testing inside the query as such :
SELECT *whatever you need*
FROM [tbl_Projects]
where
(#Category is null or [Category] = #Category) and
(#Country is null or [Country] = #country) and
(#val1 is null or value > #val1) and
(#val2 is null or value < #val2)
order by CreatedDate asc
And you always send the 4 parameters. On the plus side, you can build your query in a SQL worksheet and it's easier to spot syntax errors an so on.
You might need to add some tests for what would be an empty value, though.

Pass table valued parameter using ADO.NET

How to pass table valued parameter to stored procedure using ADO.NET?

Create type in SQL Server:
CREATE TYPE [dbo].[MyDataType] As Table
(
ID INT,
Name NVARCHAR(50)
)
Create Procedure:
CREATE PROCEDURE [dbo].[MyProcedure]
(
#myData As [dbo].[MyDataType] Readonly
)
AS
BEGIN
SELECT * FROM #myData
END
Create DataTable in C#:
DataTable myDataTable = new DataTable("MyDataType");
myDataTable.Columns.Add("Name", typeof(string));
myDataTable.Columns.Add("Id", typeof(Int32));
myDataTable.Rows.Add("XYZ", 1);
myDataTable.Rows.Add("ABC", 2);
Create SQL Parameter:
SqlParameter parameter = new SqlParameter();
parameter.ParameterName = "#myData";
parameter.SqlDbType = System.Data.SqlDbType.Structured;
parameter.Value = myDataTable;
command.Parameters.Add(parameter);

I tried this and received the exception:
The table type parameter '#MyDataType' must have a valid type name.
I had to set the "TypeName" property of the SqlParameter:
parameter.TypeName = "MyDataType";

This question is a duplicate of How to pass table value parameters to stored procedure from .net code. Please see that question for an example illustrating the use of either a DataTable or an IEnumerable<SqlDataRecord>.

For multilinguals, a little late to the show:
a) elsewhere on tsql
--- create a vector data type
CREATE TYPE [dbo].[ItemList] AS TABLE([Item] [varchar](255) NULL)
b)
Dim Invoices As New DataTable("dbo.ItemList") 'table name is irrelevant
Invoices.Columns.Add("Invoice", GetType(String))
...
With .SqlCommand.Parameters
.Clear()
.Add(New Data.SqlClient.SqlParameter() With {
.SqlDbType = Data.SqlDbType.Structured,
.Direction = Data.ParameterDirection.Input,
.ParameterName = "#Invoices",
.TypeName = "dbo.ItemList",
.Value = Invoices})
End With
...
' using store procedure
.CommandText = "SELECT * FROM dbo.rpt(#invoices) "
' or direct reference is a select
.CommandText = "SELECT * FROM dbo.invoicedata" +
"where ((select count(*) from #invoices) = 0 or "+
"InvoiceNumber in (select distinct * from #Invoices))

You can prefix with Exec
using( SqlConnection con = new SqlConnection( "Server=.;database=employee;user=sa;password=12345" ) )
{
SqlCommand cmd = new SqlCommand( " exec ('drop table '+#tab)" , con );
cmd.Parameters.AddWithValue( "#tab" ,"Employee" );
con.Open( );
cmd.ExecuteNonQuery( );
}
