Question

Now I am using one database table to another database stored procedure normally (database name..table name) but I have dynamically pass the database name how to write the stored procedure pls give me any suggestion

I am writing like this

Select QT.Name,SC.Name as Status,QT.QuoteNumber,QT.PolicyNumber,LC.Name as LineCode,QT.DBAName as DBAName       
  from QMSV3Dev..Quote QT, QMSV3Dev..StatusCode SC, QMSV3Dev..LineCode LC      
  where QT.StatusCode = SC.StatusCode And QT.LineCode = LC.LineCode and       
  QT.DBAName like 'a%' order by QT.Name,QuoteNumber desc  

In above stored procedure QMSV3Dev..Quote, QMSV3Dev is the database name and Quote is table name, this sp executed in another database like test now

Same query pass the database name dynamically

CREATE Procedure [dbo].[usp_GetSearch123]      
(      
 @SearchValue varchar(100),      
 @SearchBy varchar(250),
 @DbName varchar(50)      
)     
AS    
Begin
  Select QT.Name,SC.Name as Status,QT.QuoteNumber,QT.PolicyNumber,LC.Name as LineCode,QT.DBAName as DBAName         
  from  @DbName+'..Quote ' QT,@DbName+'.. StatusCode' SC, @DbName+'..Linecodes' LC      
  where QT.StatusCode = SC.StatusCode And QT.LineCode = LC.LineCode and       
  (QT.Name like @SearchValue+'%' or QT.DBAName like @SearchValue+'%')       
  order by QT.Name,QuoteNumber desc
 end

The answer is simpler that you think. For that, you have to use Dynamic SQL.

It would be something like this:

CREATE Procedure [dbo].[usp_GetSearch123]      
(      
 @SearchValue varchar(100),      
 @SearchBy varchar(250),
 @DbName varchar(50)      
)     
AS    
Begin

  Declare @cmd varchar(5000)

  select @cmd = 
  'Select QT.Name,SC.Name as Status,QT.QuoteNumber,QT.PolicyNumber,LC.Name as LineCode,QT.DBAName as DBAName         
  from ' + @DbName + '..Quote QT, ' + @DbName + '.. StatusCode SC, ' + @DbName+'..Linecodes LC      
  where QT.StatusCode = SC.StatusCode And QT.LineCode = LC.LineCode and       
  (QT.Name like "' + @SearchValue + '%" or QT.DBAName like "' + @SearchValue +'%")       
  order by QT.Name,QuoteNumber desc'

  exec(@cmd)
 end 

---

You create a varchar variable @cmd and put the select on it and afterwards execute it by exec(@cmd).
