No,Creates a virtual table whose contents (columns and rows) are definedby a query. Use this statement to create a view of the data in one ormore tables in the database. For example, a view can be used for thefollowing purposes:To focus, simplify, and customize the perception each user has of thedatabase.As a security mechanism by allowing users to access data through theview, without granting the users permissions to directly access theunderlying base tables.To provide a backward compatible interface to emulate a table whoseschema has changed.So, basically, this acts just like a table, and the only way that you can add 'parameters' to a table is via filter statements when accessing the view. You guys have never done this as a VIEW is a whole other table created by a query and you can include parameters in that query.it is freaking simple as wellbuild your view like you would any other with parameters.Example: USE iepaGO/. Object: StoredProcedure dbo.getBatchData Script Date: 11:41:38./SET ANSINULLS OFFGOSET QUOTEDIDENTIFIER ONGOALTER PROCEDURE dbo.getBatchData@inparm varchar(12)ASselect.from batchdatawherenow call that view like this: select from getbatchdata('61404'). View can not pass paramets directly, but you can use, for example declare @v varbinary(8)set @v = cast(cast(floor( currenttimestamp as float)) as bigint) as varbinary) -set contextinfo @v - saveselect. from myvievcreate myview aswith CTE(date) as (select cast(cast(substring(contextinfo,1,8) as bigint) as datetime) date - read)select.
