RE: How 2 convert cfquery to TSQL (MS SQL stored proc)

[Robertson-Ravo, Neil (RX)]

If you are going down the dynamic SQL route you are better off keeping it in
CF.  Dynamic SQL is very inefficient and should be avoided wherever
possible.

You want something like this (not checked, so syntax may be off a
little):

<cfset Variables.FirstName = "">
<cfif IsDefined("Form.FirstName")>
        <cfset Variables.FirstName = Form.FirstName>
</cfif>

<cfset Variables.ZipsReturned = "">
<cfif IsDefined("Form.ZipsReturned ")>
        <cfset Variables.ZipsReturned = Form.ZipsReturned >
</cfif>

<cfquery datasource="blah" name="blahquery">
        FindProfiles '#Variables.FirstName#', '#Variables.ZipsReturned#'
</cfquery>

Then, in your database, create this stored procedure by copy/pasting the
following into a Query Analyzer or other such window:

create procedure FindProfiles
        @FirstName varchar(255),
        @ZipsReturned varchar(8000)

as

set nocount on

declare @SQL varchar(8000), @WhereClause varchar(8000)

set @SQL = 'select * from Profiles
set @WhereClause = ''

if @FirstName > ''
        begin
                if @WhereClause > '' set @WhereClause = @WhereClause = '
and '
                set @WhereClause = @WhereClause + 'FirstName = ''' +
@FirstName + ''''
        end

if @ZipsReturned > ''
        begin
                if @WhereClause > '' set @WhereClause = @WhereClause = '
and '
                set @WhereClause = @WhereClause + 'Zipcode in (' +
@ZipsReturned + ')'
        end

if @WhereClause > '' set @SQL = @SQL + ' where ' + @WhereClause

execute (@SQL)
