Windows Form Application C# And Microsoft SQL Database Insert Update Delete Retrieve/Select/Display (CRUD)
This a complete (crud) Create, read, update and delete, C# Windows Form Application And Microsoft SQL Database Application/program. This desktop app demonstrates how to insert, update/edit, delete and select/retrieve data from Microsoft SQL server database and display retrieved data on c# treeview.
How To Connect To Microsoft SQL Server Database Using Microsoft SQL Server Management Studio
To access Microsoft SQL Server database you need to pass some database properties like database name and server name in sql connection string.
Below is an example of a connection String
string connectionString = "Data Source=DESKTOP-C7B0LHA\\SQLEXPRESS;Initial Catalog=Staff;Integrated Security=True";
You can get the server name when Microsoft SQL Server Management Studio is starting. As shown below.
Database.
TABLE CREATION QUERY
SID Column Auto Increments Whenever a new record is added to the database. It’s also the table primary key, that means only unique data is accepted/allowed.
USE [Staff] GO /****** Object: Table [dbo].[Newstaff] Script Date: 6/3/2021 3:50:18 AM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[Newstaff]( [SID] [int] IDENTITY(1,1) NOT NULL, [Fname] [varchar](150) NOT NULL, [lname] [varchar](150) NOT NULL, [gender] [varchar](20) NOT NULL, [dob] [varchar](100) NOT NULL, [mobile] [bigint] NOT NULL, [email] [varchar](150) NULL, [joindate] [varchar](100) NOT NULL, [city] [varchar](100) NOT NULL, [basicSalary] [decimal](8, 2) NULL, [post] [varchar](max) NULL, CONSTRAINT [PK_Newstaff] PRIMARY KEY CLUSTERED ( [SID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] GO

<!--
Microsoft ResX Schema
Version 2.0
The primary goals of this format is to allow a simple XML format
that is mostly human readable. The generation and parsing of the
various data types are done through the TypeConverter classes
associated with the data types.
Example:
... ado.net/XML headers & schema ...
<resheader name="resmimetype">text/microsoft-resx</resheader>
<resheader name="version">2.0</resheader>
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
<value>[base64 mime encoded serialized .NET Framework object]</value>
</data>
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
<comment>This is a comment</comment>
</data>
There are any number of "resheader" rows that contain simple
name/value pairs.
Each data row contains a name, and value. The row also contains a
type or mimetype. Type corresponds to a .NET class that support
text/value conversion through the TypeConverter architecture.
Classes that don't support this are serialized and stored with the
mimetype set.
The mimetype is used for serialized objects, and tells the
ResXResourceReader how to depersist the object. This is currently not
extensible. For a given mimetype the value must be set accordingly:
Note - application/x-microsoft.net.object.binary.base64 is the format
that the ResXResourceWriter will generate, however the reader can
read any of the formats listed below.
mimetype: application/x-microsoft.net.object.binary.base64
value : The object must be serialized with
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.soap.base64
value : The object must be serialized with
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.bytearray.base64
value : The object must be serialized into a byte array
: using a System.ComponentModel.TypeConverter
: and then encoded with base64 encoding.
