How to use variable in the LIKE function along with % operators

Hi,
Is there any way i can use the variable in the Like function. That means i have query like
SELECT * FROM Device WHERE DeviceName LIKE %v_MediaName%;
Here "v_MediaName" is the userdefined variable which contains string. I want to retrieve all the records from the "DEVICE" table whose DeviceName LIKE %v_MediaName%;
If i put it in a single quotes '%v_MediaName%' then the v_MediaName will be treaded as a string instead of a variable. I am using this query in a Procedure.
please help me out to resolve the issue.
thanks

LIKE '%'||v_MediaName||'%';
Will not make use of the indexes though.

Thank you all for your replies. The above proposed solution partially resolved my issue. But I am still seeing some problem.
I have a search word in the cachestore table which is 'WEP3-SEG-1'
When I execute the below query, I am expecting to see 'WEP3-SEG-1' in the output
Declare @LineName varchar(50) = 'WEP3-SEG-1A'
Select * From
CacheStore where @LineName like
'%' + SearchWord
+ '%'
But I am getting all the below search words along with 'WEP3-SEG-1'
ID           SearchWord
2                P
3               %
4               -
5               3
6             'WEP3-SEG-1'
I just want to see this in the output
ID              SearchWord
6               'WEP3-SEG-1'
How to achieve this? Thanks again for all your help.

How to use variables in the mail text while sending mails through workflows

I had prepared a workflow in which i am sending mail to a administrator if personnel data of any employee is changed.But i want to send the personnel no of employee whose data have been changed.How can i send this personnel no in the mail.
Points will be rewarded for useful answer.

Hi Anand,
You have the "EmployeeNumber" field in the event container. Pass this into the workflow container by defining a Workflow Container element and subsequently use this container as a variable in your email using insert fields option and you will have the PersonNumber visible in your mail sent to the administrator.

How to use database look up table function in xsl mapping

Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

How to put decimal in the substring function

Hi Friends
I am having a input value which is a UDF named GetValue which is mapped with a substring (0,4) which is again mapped to a split by value and then to the target field MENGE
My problem is when value is coming from GetValue and i am mapping it to substring there i want to take the decimals also
forexample let us value coming is 2 than in the substring and then to the target field i want to send as 2.000.
Please help me how it can be done.
Thanks

Hi Aquarian,
The value which is coming from GetValue UDF, map that to a FormatNumber Function
Use the standard function 'formatnumber' with number format 0.00
double click on 'formatnumber' function in mapping editor to get number format field.
you need not put anything in the 'decimal separator' field.
this function is available in arithmetic set of standard functions.
I believe this should be it.
Let me know if you need more help.
Thanks,
Varun

How does the sync functionality work with large libraries on small devices?

How does the sync functionality work with large libraries?
Say I sync 100gb of photos with the new Photos app and turn on sync on a 16gb iphone. Will it fill the device up to 16gb? Can I tell it to limit to xgb so I leave room for music and apps? How does this work? Will it slow down my phone if its trying to sync 100gb across smaller devices?

"Will the Apple TV now read directly from the Time Capsule?" ATV does not 'read' from the TC. It connects to the Mac and itunes library associated with the Mac. Of course the itunes program can 'point' to a library on the TC. You'll still need to have itunes open and the Mac powered on and not sleeping with the TC mounted to the Desktop to use ATV properly. So bottom line the use of TC just adds one more step to view files on the ATV.
