I am using sql OPENQUERY to check if record exist passing parameter update it, if not insert a new record.
Here is what I have so far
DECLARE #sql VARCHAR (8000)
DECLARE #Id VARCHAR(20)
SET #Id= '31124'
SET #sql = '
SELECT * FROM OPENQUERY
(
SERVERNAME,
''
SELECT Name FROM table WHERE Id= ''''' + #Id + '''''
''
)'
EXEC (#sql)
DECLARE #sql VARCHAR (8000)
DECLARE #Id VARCHAR(20)
SELECT #Id= '31124'
SELECT #sql =
'
IF EXISTS
(
SELECT * FROM OPENQUERY
(
SERVERNAME,
''SELECT Name FROM table WHERE Id= ''''' + #Id + '''''''
)
)
BEGIN
UPDATE OPENQUERY
(
SERVERNAME,
''SELECT Name FROM table WHERE Id= ''''' + #Id + '''''''
)
SET Name = ''NewName''
ELSE
INSERT OPENQUERY
(
SERVERNAME,
''SELECT Name FROM table''
)
VALUES
(
''NewName''
)
END
'
EXEC (#sql)
Unless you have some specific requirement to use EXEC, you don't need it.
DECLARE #Id VARCHAR(20)
SELECT #Id= '31124'
IF EXISTS
(
SELECT * FROM OPENQUERY
(
SERVERNAME,
'SELECT Name FROM table WHERE Id= ''' + #Id + ''''
)
)
BEGIN
UPDATE OPENQUERY
(
SERVERNAME,
'SELECT Name FROM table WHERE Id= ''' + #Id + ''''
)
SET Name = 'NewName'
ELSE
INSERT OPENQUERY
(
SERVERNAME,
'SELECT Name FROM table'
)
VALUES
(
'NewName'
)
END

What i am trying to do looks like the following
insert into user_audit
( SELECT COLUMN_NAME
FROM information_schema.columns
WHERE TABLE_NAME='user' and TABLE_SCHEMA = database() )
VAlUES ( SELECT * FROM `user` where id = NEW.id )
Insert into user_audit the column name of user table and the values of user table
Thanks for helping
Can you please try the following Dynamic SQL: It might help
declare #insertquery nvarchar(1000)
Declare #ColumnNames varchar(2000)
select #ColumnNames = COALESCE(#ColumnNames + ', ', '') + COLUMN_NAME
from
INFORMATION_SCHEMA.COLUMNS
where
TABLE_NAME='user' and TABLE_SCHEMA = database();
set #insertquery = N'insert into user_audit(' + #ColumnNames + ') SELECT * FROM `user` where id = NEW.id;
sp_executesql #insertquery
I have a Emplyee table as Follow,
https://i.stack.imgur.com/WjtM6.png
In every Updation(any column Delete,Update) ineed save that details to another table for security purpose.That tbale structure as following.
https://i.stack.imgur.com/Yv1YD.png
I can write a Code in my programe to do this job, but Can i write a trigger to Automatically saved old data to employee updation table using triger?
in a MySql that function availble, I dont Konw about MS SQL.
thank you!
i would suggest to create audit table similar to original table
IF NOT EXISTS
(SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[Audit]')
AND OBJECTPROPERTY(id, N'IsUserTable') = 1)
CREATE TABLE Audit
(Type CHAR(1),
TableName VARCHAR(128),
PK VARCHAR(1000),
FieldName VARCHAR(128),
OldValue VARCHAR(1000),
NewValue VARCHAR(1000),
UpdateDate datetime,
UserName VARCHAR(128))
GO
Then work on the trigger as below, which can track, INSERT, UPDATE and DELETE operations.
CREATE TRIGGER TR_GUESTS_AUDIT ON dbo.IBIS_UnitSchedule FOR UPDATE

Hi all I have written the following Procedure to display the results as pivot as per the requirement
DECLARE #values AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #values = STUFF(
(
SELECT DISTINCT ',[' + ColumnName + ']'
FROM xTable
FOR xml path ('')
),1,1,'')
SET #query = 'SELECT viewName1.*, pValues.Code, ' + #values + ' FROM
(
SELECT Column1,Column2, Column3
FROM viewname
) aliasName
PIVOT
(
MAX(value)
FOR ColumnName in (' + #values + ')
) pValues INNER JOIN viewName1 ON pValues.Code = viewname.Code'
EXEC(#query)
But when the value and column names are same in my xTable and viewName1 I am getting that error how can I resolve this. I tried with alas but I am not getting the expected result so can some one help me.
Sample is I am having a ColumnName as TopBrand in my table xTable, this can be a value in my viewName1 like for X Column TopBrand can be a value.
I think you need to have a separate list for FOR and IN clauses and the former should include the alias:
DECLARE #valuesFor AS NVARCHAR(MAX),
#valuesIn AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #valuesFor = STUFF(
(
SELECT DISTINCT N',pValues.[' + ColumnName + ']'
FROM xTable
FOR xml path ('')
),1,1,'')
SELECT #valuesIn = STUFF(
(
SELECT DISTINCT N',[' + ColumnName + ']'
FROM xTable
FOR xml path ('')
),1,1,'')
SET #query = N'SELECT viewName1.*, pValues.Code, ' + #valuesFor + N' FROM
(
SELECT Column1,Column2, Column3
FROM viewname
) aliasName
PIVOT
(
MAX(value)
FOR ColumnName in (' + #valuesIn + N')
) pValues INNER JOIN viewName1 ON pValues.Code = viewname.Code'
EXEC(#query)
I have a query that outputs just one row of data. I want to convert that row to column and the column to row.
My original query
------------------------
ID Name Desc
------------------------
1 Nisha Some desc
what I need
--------------------------
FieldName FieldValue
--------------------------
ID 1
