In this article I will explain how to write query to get last inserted record id in sql server or last modified record id value in SQL Server.
Before write query first design one table and give name as EmployeeDetails in your database as shown below
In this article I will explain how to write query to get last inserted record id in sql server or last modified record id value in SQL Server.
Description:
In
previous post I explained how to set identity property or auto increment column in data
table and many articles relating to SQL
Server.
Now I will explain how to write a query to get last inserted record id value or
last modifies record id in SQL
Server.
Generally if we create data table we will set identity column or auto increment column in table to increase column id value
automatically whenever new record inserted in SQL Server. In one situation I got
requirement like to get last inserted record Id from data table in SQL Server.
Before write query first design one table and give name as EmployeeDetails in your database as shown below
EmployeeDetails
Table
Column Name
|
Data Type
|
Allow Nulls
|
EmpId
|
Int
(set Identity=true)
|
No
|
EmpName
|
varchar(50)
|
Yes
|
Role
|
Varchar(50)
|
Yes
|
To
insert new record in above table we need to write query like this
INSERT INTO
EmployeeDetails(EmpName,Role) VALUES('SureshDasari','Team Lead')
|
Now
if we want to get last inserted record we have multiple options check below
queries
The
table which is having Identity Property from that table we can get the last
inserted record id will be like this
SELECT @@IDENTITY
SELECT SCOPE_IDENTITY()
SELECT IDENT_CURRENT('TableName')
|
Another way we can get it in
SELECT MAX(EmpId) FROM EmployeeDetails
|
Other way
SELECT TOP 1 EmpId FROM EmployeeDetails ORDER
BY EmpId DESC

I am fan of ur posts...
tell me what if Identity=false?
if identity is false you need to increment id by yourself so as not to conflict with previous id and use SELECT TOP 1 EmpId FROM EmployeeDetails ORDER BY EmpId DESC
how to write both queries in single line i mean how to get identity id after inserting a row in single query...l
Dim a As String
a = "select TOP 2 RecieptNo, Date,TutionFeeRs,TutionFeePs from tutuionreciept where AppNo =" & TextBox1.Text & " "
cmd = New SqlCommand(a, con)
cmd.Connection = con
dr = cmd.ExecuteReader
dr.Read()
If (dr.HasRows = True) Then
TextBox14.Text = dr.GetValue(0)
TextBox16.Text = dr.GetValue(1)
TextBox15.Text = dr.GetValue(2) + dr.GetValue(3)
End If
dr.NextResult()
dr.Read()
If (dr.HasRows = True) Then
While (dr.NextResult = True)
TextBox19.Text = dr.GetValue(0)
TextBox18.Text = dr.GetValue(1)
TextBox17.Text = dr.GetValue(2) + dr.GetValue(3)
dr.NextResult()
End While
Else
MsgBox("No record")
End If
