can any one do this ??
I have searched high and low, without finding an answer. So I hope that you guys n girls can help me on my way:
I cant figure out why #old_comment is NULL when I use it in "SET #new_comment...", but it returns a fine value when I use it in the outputparameter "SET #commentOldOUT..."
CREATE PROCEDURE [dbo].[SP_NY_KOMMENTAR]
#tabel NVARCHAR(100),
#id INT,
#comment NVARCHAR(1000) = NULL,
#commentOldOUT NVARCHAR(1000) = NULL OUTPUT
AS
BEGIN
SET NOCOUNT ON;
DECLARE #user NVARCHAR(30);
DECLARE #date NVARCHAR(10);
DECLARE #new_id VARCHAR(100);
DECLARE #new_comment NVARCHAR(MAX);
DECLARE #old_comment NVARCHAR(MAX);
DECLARE #old_comm NVARCHAR(MAX);
DECLARE #old NVARCHAR(MAX);
DECLARE #q2 NVARCHAR(MAX);
SET #new_id = (SELECT CAST(#id AS VARCHAR(100)));
SET #user = (SELECT ORIGINAL_LOGIN());
SET #date = (SELECT CONVERT(DATE,GETDATE()));
SET #old = 'SELECT comment FROM '+ #tabel +' WHERE id = ' + #ny_id;
EXEC sp_executesql
#query = #old,

SET #q2 = N'UPDATE ' + #tabel + ' SET comment = ''' + #new_comment + ''' WHERE id = ' + #ny_id;
EXEC (#q2);
END
Sorry, I tried your query but for me it works fine! Have you tried to "debug" your query? You can see the value of every variable when in debug. (The green arrow in SQL Server 2008)
I'm guessing that you didn't pass a value explicitly for the #comment parameter? If so, the problem would be here:
SET #new_comment = COALESCE(#old_comment + CHAR(13),'') + '[' + #user + ' ' + #date + '] ' + #comment;
The parameter #comment has a default value of NULL and concatenating anything with NULL results in NULL. That would explain why #old_comment, #user and #date all have values, but when it put it all together then #new_comment is NULL. This would be a better default value:
#comment NVARCHAR(1000) = '',
And your code as written is a bit messy, I assume that #old_comment and #commentOldOUT are only for debugging purposes? I don't see why you don't use #old_comm directly.
Finally, if you're working with dynamic SQL then I strongly recommend adding a debugging parameter to print out your SQL strings easily. It's a very useful troubleshooting tool, especially if you don't have SSMS available.
Well I can now see that I did several things wrong, below is the new, and now working, stored procedure:
CREATE PROCEDURE [dbo].[SP_NY_KOMMENTAR]
#tabel NVARCHAR(100),
#id INT,
#comment NVARCHAR(1000) = NULL
AS
IF #comment IS NOT NULL
BEGIN
SET NOCOUNT ON;
DECLARE #user NVARCHAR(30);
DECLARE #date NVARCHAR(10);
DECLARE #SQLSelect nvarchar(500);
DECLARE #ParmSelect nvarchar(500);
DECLARE #old_comment NVARCHAR(MAX);
DECLARE #old_commentOUT NVARCHAR(MAX);
DECLARE #new_comment NVARCHAR(MAX);
DECLARE #SQLUpdate nvarchar(500);
DECLARE #ParmUpdate nvarchar(500);
SET #user = (SELECT ORIGINAL_LOGIN());
SET #date = (SELECT CONVERT(DATE,GETDATE()));
SET #SQLSelect = N'SELECT #old_commentOUT = kommentar FROM ' + QUOTENAME(#tabel) + ' WHERE id = #id';
SET #ParmSelect = N'#id INT, #old_commentOUT NVARCHAR(MAX) OUTPUT';
EXEC sp_executesql
#SQLSelect,
#ParmSelect,
#id = #id,
#old_commentOUT = #old_comment OUTPUT;
SET #old_comment = (SELECT #old_comment);
SET #new_comment = COALESCE(#old_comment + CHAR(13) + CHAR(10),'') + '[' + #user + ' ' + #date + '] ' + #comment;
SET #SQLUpdate = N'UPDATE ' + QUOTENAME(#tabel) + ' SET kommentar = #new_comment WHERE id = #id';
SET #ParmUpdate = N'#id INT, #new_comment NVARCHAR(MAX)';
EXEC sp_executesql
#SQLUpdate,
#ParmUpdate,
#id = #id,
#new_comment = #new_comment;
END
For example I weren't using parameterbinding correct, after that I tried to bind tabelnames as a parameter...
I want to get all the transactions applied on a specific table in SQL Server 2008.
I found the last time a table was updated using this script:
SELECT OBJECT_NAME(OBJECT_ID) AS DatabaseName, last_user_update,*
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID( 'DBName')
AND OBJECT_ID=OBJECT_ID('tableName')
I want to know all the transactions (Inserts, Updates, Deletes) for that table, and their datetime, and the query applied.
What is the best way to do this?
The only way to do this in a reasonable amount of time is to use a third party tool(as Martin said in first comment) such as ApexSQL Log that can read transaction log and get the information you need.
Note that in order for this to work your database has to be in a full recovery mode because that’s when SQL Server logs full transaction details that can be reconstructed later.
Another option is to investigate how to use undocumented fn_dblog function but this will take you a lot more time and you won’t be able to read detached logs or transaction log backups.
creating a trigger which will create a new table Emp_audit and add new tuples to it whenever any change is made to table employee
create trigger my_trigger on Employees
AFTER INSERT, UPDATE, DELETE
AS
DECLARE #What varchar(30);
DECLARE #Who varchar(30);
DECLARE #for int;
DECLARE #At time;
DECLARE #COUNTI int;
DECLARE #COUNTD int;
select #COUNTI = COUNT(*) from inserted;
select #COUNTD = COUNT(*) from deleted;
set #Who = SYSTEM_USER;
set #At = CURRENT_TIMESTAMP;
if( #COUNTD = 0 and #COUNTI = 1)
begin
set #What = 'insert';
select #for = EmployeeID from inserted i;
end
else
begin
if( #COUNTD = 1 and #COUNTI = 0)
begin
set #What = 'delete';
select #for = EmployeeID from deleted i;
end
else
begin
set #What = 'update';
select #for = EmployeeID from inserted i;
end
end
INSERT INTO EMP_Audit Values (#What, #Who, #for, #At);
You would be much better off setting up auditing for this need rather than trying to extract this information retrospectively from the transaction log.
If you are on Enterprise Edition you could use the built in SQL Server Audit functionality, otherwise it should be relative straight forward to log the desired information via triggers.
You could create your own transaction logs
Step 1: Create your own table for transaction logs
CREATE TABLE [dbo].[TransactionLogs](
[TransactionLogID] [bigint] IDENTITY(1,1) NOT NULL,
[Query] [nvarchar](max) NOT NULL,
[DateCreated] [datetime] NOT NULL,
CONSTRAINT [PK_TransactionLogs] PRIMARY KEY CLUSTERED
(
[TransactionLogID] 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
Step 2: Create stored procedure that create logs. (Note: Replace YourTablePKColumn with your table primary key column.)
create procedure [dbo].[sp_CreateQueryLogs]

create table #tmpValues(ColumnValues nvarchar(max))
insert into #tmpValues(ColumnValues)
exec('select CAST ( ( select * from ' + #TableName + ' where YourTablePKColumn = ' + #YourTablePKColumn + '

deallocate updatedCursor;
end
declare updatedCursor cursor local for
select cast(YourTablePKColumn as nvarchar(30)) from inserted;
open updatedCursor;
fetch next from updatedCursor

Having an issue concatenating the following statement.
Basically I want the length column to add inches after but it will not run. I am going to create a function out of this in the future but unable to get past this step. What gives?
declare #column varchar(255)
declare #sql varchar(5000)
declare #additional varchar(500)
set #column = 'length'
set #additional = 'inches'
select #sql = 'select distinct ps.p_c_id, '
select #sql = #sql + #column + ' '+#additional+ ' ' + ' as value'
select #sql = #sql
select #sql = #sql + ' from dbo.Product ps
inner join dbo.ProductAttributes psa on psa.p_s_id = ps.p_s_id
where ps.p_c_id is not null and ' + #column + ' is not null'
exec (#sql)
You are concatenating, what i'm assuming is an int or float value to a string ' inches'...have to cast the "length" value as a varchar...
just select your #sql next time to see the resulting syntax and it should jump out at you. here is changes that should work
BTW...look at implementing EXEC sp_executesql ...makes dynamic sql less suseptable to injection by using parameters, etc... look up in Books OnLine
Sorry...eating Crow...sp_executesql does not protect from injection just improves performance in general...see article MSDN SQL Injection
declare #column varchar(255)
declare #sql varchar(5000)
declare #additional varchar(500)
set #column = 'psa.length'
set #additional = 'inches'
select #sql = 'select distinct ps.p_c_id, '
select #sql = #sql + 'CAST(' + #column + ' AS varchar(10)) + ' + ''' '+#additional+ ''' ' + ' as value'
select #sql = #sql
select #sql = #sql + ' from dbo.Product ps
inner join dbo.ProductAttributes psa on psa.p_s_id = ps.p_s_id
where ps.p_c_id is not null and ' + #column + ' is not null'
--select #sql AS [ExecutableSQL]
exec(#sql)
Your output is;
select distinct ps.p_c_id, length inches as value from dbo.Product ps
inner join dbo.ProductAttributes psa on psa.p_s_id = ps.p_s_id
where ps.p_c_id is not null and length is not null
So it looks like a missing , between length inches assuming you want both;
select #sql = #sql + #column + ','+ #additional+ ' ' + ' as value'
Using Sql Server 2008, developed a view "vw_MasterView" I get this error:
Conversion failed when converting the nvarchar value 'SELECT * FROM VW_MASTERVIEW v WHERE 1=1 AND v.ClinicId = '' to data type int.

ALTER PROCEDURE [dbo].[ClientSummary1]

declare #sql nvarchar(2000);
SET NOCOUNT ON
set #sql = 'SELECT * FROM VW_MASTERVIEW v WHERE 1=1 ';
IF #LocationId is not null
begin
set #sql = #sql + ' AND v.LocationId = ''' + #LocationId + '''';
end
if #userName is not null
begin
set #sql = #sql + ' AND (v.FirstUser = '' OR v.SecondUser = '')' + #userName + '''';
end
if #startDate is not null
begin
set #sql = #sql + ' AND v.FirstVisitDate = ''' + #startDate + '''';
end
if #endDate is not null
begin
set #sql = #sql + ' AND v.LastVisitDate = ''' + #endDate + '''';
end
EXEC(#sql)
I get both the LocationId and userName from a VS2010 application.
Thanks in Advance
When appending strings together in SQL Server, you have to cast non-textual types (such as int) to a textual type (such as varchar):
set #sql = #sql + ' AND v.LocationId = ''' +
cast(#LocationId as varchar(10)) + '''';
-- ^^^^ have to cast ^^ make sure size is big enough
Note that dynamic SQL should not be necessary in the first place. You can just run the query directly with the parameters (I implemented the null checks with the extra or conditions):
SELECT * FROM VW_MASTERVIEW v
WHERE (v.LocationId = #LocationId OR #LocationId is null)
AND (v.FirstUser = #userName OR v.Seconduser = #userName OR #userName is null)
AND (v.FirstVisitDate = #startDate OR #startDate is null)
AND (v.LastVisitDate = #endDate OR #endDate is null)
I may not have the logic right for FirstUser and SecondUser - I took an educated guess from your incomplete code.
Hope this helps!
