SQL Server VARBINARY(MAX) - c#

I have a stored procedure that inserts a varchar & VARBINARY(MAX) values in the table.
I pass a c# byte[] to the varbinary(max) field. I also see that the size of the byte[] size is 80142 which satisfies the max limit of varbinary. Stored procedure executes without any errors. But when I try to query that table I see empty values in the varbinary datatype.
SQL sp
ALTER PROCEDURE [dbo].[Test]
-- Add the parameters for the stored procedure here
#PNumber varchar(50)
,#Byte varbinary(max)
AS
BEGIN
SET NOCOUNT ON;
-- Insert statements for procedure here
INSERT INTO [Test].[dbo].[Data]
([PNumber]
,[PByte])
VALUES
(#PNumber
,#Byte)
END
C# CODE
byte[] theData = doc.GetData();
DAL_DataTableAdapters.QueriesTableAdapter qta = new DAL_DataTableAdapters.QueriesTableAdapter();
qta.Test("test", theData);
Table structure:
CREATE TABLE [dbo].[Data]
(
[ID] [int] IDENTITY(1,1) NOT NULL,
[PNumber] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[PByte] [varbinary](max) NULL
) ON [PRIMARY]


How do you determine that the data is empty? I'm quite certain that SQL Server Management Studio will not display a value that is too long (I don't know the limit), even when the value is there.

I have 2 tables :
CREATE TABLE [dbo].[Accessoires1]
(
[ID] [int] IDENTITY(1,1) NOT NULL,
[Date] [datetime] NOT NULL,
[ClientID] [int] NOT NULL,
[TotalPrice] [varchar](50) NOT NULL
)
CREATE TABLE [dbo].[Accessoires2]
(
[Accessoire1_ID] [int],
[Date] [datetime] NOT NULL,
[ClientID] [int] NOT NULL,
[TotalPrice] [varchar](50) NOT NULL
)
Then I have a stored procedure Proc1 that insert values into table Accessoire1, and I have Proc2 which adds data to accessoires2 - but it needs the a specific accessoire1_ID
In my C# code, I execute those procedures at the same exact time so I need the Accessoires1.ID to be inserted into accessoires2 - how can I manage to do that?

In your first procedure do this:
CREATE PROCEDURE nameOfSp
#col1 VARCHAR(20),
#newId INT OUTPUT
AS
BEGIN
SET NOCOUNT ON
-- your code
-- assign identity to variable
SELECT #newId = SCOPE_IDENTITY()
RETURN
END
Your c# code will need to call the first stored procedure and passing it an output parameter like this:
SqlParameter newId = new SqlParameter();
newId.ParameterName = "#newId";
newId.DbType = DbType.Int32;
newId.Direction = ParameterDirection.Output;
After the first procedure is executed, your C# code can get the value of newId returned like this:
int outValue = (int) newId.Value;
Now you can pass it to your 2nd procedure.

Stored Procedure Storing 0 in Auto increment column in Table

I have the following table where ProspectCode is Identity Not Null
Table LeadMastersNew
ProspectCode int
CompanyName nvarchar(50)
PersonName nvarchar(50)
Designation nvarchar(50)
Number nvarchar(50)
Number2 nvarchar(50)
Emailaddress nvarchar(50)
Address nvarchar(MAX)
Address2 nvarchar(MAX)
CityName nvarchar(50)
State nvarchar(50)
PinNumber nvarchar(50)
Product nvarchar(50)
RemarkNote nvarchar(MAX)
The issue which I am facing lately is that when I am storing records to the above table using stored procedure,ProspectCode is always set to 0 for all the rows that I add.I have 160 Records in the above table,But when I add new Record, its ProspectCode is set to 0 for all the record that I add.
Stored Procedure
ALTER Procedure [dbo].[Proc_InsertLeads]
#ProspectCode nvarchar(50),#CompanyName nvarchar(50),#PersonName nvarchar(50),#Designation nvarchar(50),#Number nvarchar(50),
#Number2 nvarchar(50),#Emailaddress nvarchar(50),#Address nvarchar(MAX),#Address2 nvarchar(MAX),
#CityName nvarchar(50),#State nvarchar(50),#PinNumber nvarchar(50),#Product nvarchar(50),#RemarkNote nvarchar(MAX)
AS
BEGIN
SET IDENTITY_INSERT LeadMastersNew ON;
INSERT INTO LeadMastersNew
(ProspectCode,CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote)
VALUES(#ProspectCode,#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote)
INSERT INTO LoggerLeadMasters
(ProspectCode,CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote,Activity,ActivityTime)
VALUES(#ProspectCode,#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote,'New Record Added',getdate())
SET IDENTITY_INSERT LeadMastersNew OFF;
END
EXEC Proc_InsertLeads'ABc','Mr abc','MD','PhoneNumber','','abc#abcindia.com','xyz','','Mumbai','Maharashtra','400059','Abc', 'Abc'
Sets ProspectCode to 0
Can anyone help me to fix this issue? Do I have to change my stored Procedure or Table Schema?
Thanks

If you want an identity column to assign numbers automatically, the thing you really shouldn't be doing is setting IDENTITY_INSERT to ON. Turning that setting on says to SQL Server "trust me, I'll provide the values in the identity column".
You probably want code something like:
BEGIN
DECLARE #NewID int
INSERT INTO LeadMastersNew
(/*ProspectCode,*/CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote)
VALUES(/*#ProspectCode,*/#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote)
SET #NewID = SCOPE_IDENTITY()
INSERT INTO LoggerLeadMasters
(ProspectCode,CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote,Activity,ActivityTime)
VALUES(#NewID ,#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote,'New Record Added',getdate())
END
This may not work exactly first time since I can't reconcile the code you've shown with how you're calling it. If ProspectCode is indeed an int column and you're actually trying to insert an nvarchar value of 'Choice Brokers', you should be getting an error.

you don't need identity_insert if you set autoincrement
remove rows
SET IDENTITY_INSERT LeadMastersNew ON;
SET IDENTITY_INSERT LeadMastersNew OFF;
and it should work

Here ProspectCode must set to Auto-increment since it is identity column for table. So basically in store procedure you must remove input parameter #ProspectCode and while inserting new row don't ON OFF IDENTITY_INSERT on table, final store procedure look like:
ALTER Procedure [dbo].[Proc_InsertLeads]
#CompanyName nvarchar(50),#PersonName nvarchar(50),#Designation nvarchar(50),#Number nvarchar(50),
#Number2 nvarchar(50),#Emailaddress nvarchar(50),#Address nvarchar(MAX),#Address2 nvarchar(MAX),
#CityName nvarchar(50),#State nvarchar(50),#PinNumber nvarchar(50),#Product nvarchar(50),#RemarkNote nvarchar(MAX)
AS
BEGIN
DECALRE #ID INT = 0
INSERT INTO LeadMastersNew
(CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote)
VALUES(#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote)
SET #ID = SCOPE_IDENTITY()
INSERT INTO LoggerLeadMasters
(ProspectCode,CompanyName,PersonName,Designation,Number,Number2,Emailaddress,Address,Address2,CityName,State,PinNumber,Product,RemarkNote,Activity,ActivityTime)
VALUES(#ID,#CompanyName,#PersonName,#Designation,#Number,#Number2,#Emailaddress,#Address,#Address2,#CityName,#State,#PinNumber,#Product,#RemarkNote,'New Record Added',getdate())
END
Here I am using #ID parameter to find newly inserted ProspectCode in table LeadMastersNew which will used in table LoggerLeadMasters as ProspectCode.

Storing XML file in SQL Server 2008 R2 express

I am trying to store XML data into a SQL Server 2008 R2 Express database, every xml file has different data. What is the easiest way to do this?
What are the best options please explain with example.

I believe easiest way will be to create a stored procedure to handle the storage for you. You can then retrieve it by an ORM of preferage and let C# deserialize it for you.
CREATE TABLE [dbo].[MyXmlStorage]
(
[Id] [int] IDENTITY(1,1) NOT NULL,
[FileName] [nvarchar](255) NOT NULL,
[Xml] [xml] NOT NULL,
CONSTRAINT [PK_MyXmlStorage]
PRIMARY KEY CLUSTERED ([Id] ASC)
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
CREATE PROCEDURE [dbo].[InsertXml]
(#filePathFull nvarchar(255))
AS
DECLARE #xmlAsString VARCHAR(MAX)
DECLARE #sql nvarchar(max)
DECLARE #xml XML
DECLARE #Rms_FileId nvarchar(50)
DECLARE #Rms_Id nvarchar(50)
DECLARE #Rms_Type nvarchar(50)
DECLARE #Rms_Timestamp nvarchar(50)
BEGIN
SET #sql = 'SELECT #xmlAsString = x.y FROM OPENROWSET( BULK ''' + RTRIM(#filePathFull) + ''', SINGLE_CLOB) x(y)'
exec sp_executesql #sql,N'#xmlAsString VARCHAR(MAX) OUTPUT',#xmlAsString OUTPUT
set #xml = CONVERT(XML,#xmlAsString)
INSERT INTO MyXmlStorage([FileName],[Xml])
VALUES (#filePathFull, #xml)
END
Then run it like this:
exec InsertXml N'C:\files\xmlfile.xml'

Ok, this is an example for storing the values of the xml into the table instead. I havent't tried this code but it should be working but at least it should clarify how to do as expected.
/* Imagine your xml looks something like this
<Content>
<Title>Text</Title>
<Value>15</Value>
</Content>
*/
CREATE TABLE [dbo].[MyXmlStorage]
(
[Id] [int] IDENTITY(1,1) NOT NULL,
[Title] [nvarchar](100) NOT NULL,
[Value] int NOT NULL,
CONSTRAINT [PK_MyXmlStorage]
PRIMARY KEY CLUSTERED ([Id] ASC)
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
CREATE PROCEDURE [dbo].[InsertXml]
(#filePathFull nvarchar(255))
AS
DECLARE #xmlAsString VARCHAR(MAX)
DECLARE #sql nvarchar(max)
DECLARE #xml XML
DECLARE #Rms_FileId nvarchar(50)
DECLARE #Rms_Id nvarchar(50)
DECLARE #Rms_Type nvarchar(50)
DECLARE #Rms_Timestamp nvarchar(50)
BEGIN
SET #sql = 'SELECT #xmlAsString = x.y FROM OPENROWSET( BULK ''' + RTRIM(#filePathFull) + ''', SINGLE_CLOB) x(y)'
exec sp_executesql #sql,N'#xmlAsString VARCHAR(MAX) OUTPUT',#xmlAsString OUTPUT
set #xml = CONVERT(XML,#xmlAsString)
/* Use xpath to query nodes for values inside the Content tag*/
INSERT INTO MyXmlStorage([Title],[Value])
SELECT
x.y.value('title[1]/text()[1]', 'nvarchar(100)') AS title,
x.y.value('value[1]/text()[1]', 'int') AS value
FROM #xml.nodes('//Content') AS x(y)
END
)

How to get some extra info description of a mysql table

I found in stackoverflow a link who explains this question. I wrote a procedure who does that but the retreived data is not as it's expected by mysql
Here is data that I receive using procedure (this gives an error when I use it for creating a table in this form, the error is syntax error near id int(11))
CREATE TABLE IF NOT EXISTS `atelier`(
`id` int(11) NO PRI auto_increment
`nom` varchar(30) NO UNI
`at_date` date NO
`pax` int(11) NO
`prix` double NO
`vente` double YES
`note` varchar(200) YES
`cr_user` varchar(15) NO
`cr_date` datetime NO
`up_user` varchar(15) YES
`up_date` datetime YES
And here is the data given by phpmyadmin
CREATE TABLE `Atelier` (
`id` int(11) NOT NULL auto_increment,
`nom` varchar(30) NOT NULL,
`date` date NOT NULL,
`pax` int(11) NOT NULL,
`prix` double NOT NULL,
`vente` double default NULL,
`note` varchar(200) default NULL,
`cr_user` varchar(15) NOT NULL,
`cr_date` datetime NOT NULL,
`up_user` varchar(15) default NULL,
`up_date` datetime default NULL,
PRIMARY KEY (`id`)
) ENGINE=Innodb DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
What I want to know should I do translation of YES AND NO within my program or there is a way to obtain it with a query, and with wich query I can obtain info of two last lines given by phpmyadmin.(I think they are usefull for the choose of ENGINE and define the unique and primary keys)
PS:Using c#, and names of the tables I get from another procedure that exist in my program. I don't get it with DESCRIBE. What I receive is between id and up_date.
Here is the link of my procedures MY PROCEDURES

You didn't show the procedure generating this output, but if you replace DESCRIBE in there with SHOW CREATE TABLE I suppose it will work.

Stored Procedure with IsIDenity and cmd.Parameters.Add

I am creating an ASP.NET Wiki for myself to track the knowlege I gain in C# and other language.
I have created a Stored Procedure to insert a category into a DB, the DB has two fields C_ID(int) and Category(varchar 25). In my ASP page, there is no field for C_ID, it increments automatically by IsIdentiy = true;
When I try to excute it, it fails. What is the best approach to handle this?
Code:
ALTER PROCEDURE dbo.InsertCategory
#ID int,
#CATEGORY varchar(25)
AS
INSERT INTO Wiki
(C_ID, C_Category)
Values (#ID, #CATEGORY)
/* SET NOCOUNT ON */
RETURN
Did I miss something to insert from the .aspx page?
try
{
//create a command object identifying the Stored Procedure
SqlCommand cmd = new SqlCommand("InsertCategory", conn);
//Set the command type
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("Category", txtAddCatagory));
cmd.ExecuteNonQuery();
}

Just omit the id from the insert. If you configured identity correctly, the database will take care of increasing the number. For example:
GO
ALTER PROCEDURE dbo.InsertCategory(#CATEGORY varchar(25))
AS
INSERT INTO Wiki (C_Category) Values (#CATEGORY)
GO
To verify the identity is set correctly, if you script the table, the C_id column should look like;
[C_id] [int] IDENTITY(1,1) NOT NULL,
Or even better:
[C_id] [int] IDENTITY(1,1) PRIMARY KEY,

So you're getting an exception that you cannot insert into an identity column, right? The trick is to not specify the identity column in your insert statement, because it automatically get populated... ;)
ALTER PROCEDURE dbo.InsertCategory #CATEGORY varchar(25) AS
INSERT INTO Wiki (C_Category) Values (#CATEGORY) /* SET NOCOUNT ON */ RETURN
