CF Declaring SQL variables
Hi all, I've a section of query I'm trying to run, I've tried lots of different ways to write it but have had no success yet Does anyone know how this query should be written: [code] cfquery name=breadcrumb datasource=#REQUEST.theDatabase# !---SELECT the values for the Deleted level into variables--- DECLARE DeletedAreaName VARCHAR(50); DECLARE DeletedLft INTEGER; DECLARE DeletedRgt INTEGER; SELECT SiteAreaName, Lft, Rgt INTO DeletedAreaName, DeletedLft, DeletedRgt FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#' /cfquery [/code] Thanks, Richard ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:244615 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: CF Declaring SQL variables
without testing: I think the into only takes the name of the (new) table If you need to change the column names you could try it like this: SELECT SiteAreaName as DeletedAreaName, Lft as DeletedLft , Rgt as DeletedRgt INTO DeletedArea FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#' - Original Message - From: Richard Cooper [EMAIL PROTECTED] To: CF-Talk cf-talk@houseoffusion.com Sent: Friday, June 23, 2006 12:39 PM Subject: CF Declaring SQL variables Hi all, I've a section of query I'm trying to run, I've tried lots of different ways to write it but have had no success yet Does anyone know how this query should be written: [code] cfquery name=breadcrumb datasource=#REQUEST.theDatabase# !---SELECT the values for the Deleted level into variables--- DECLARE DeletedAreaName VARCHAR(50); DECLARE DeletedLft INTEGER; DECLARE DeletedRgt INTEGER; SELECT SiteAreaName, Lft, Rgt INTO DeletedAreaName, DeletedLft, DeletedRgt FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#' /cfquery [/code] Thanks, Richard ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:244616 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: CF Declaring SQL variables
It's not strictly that I need to change the column names... I was planning to use them within the same query like this: [code] cfquery name=breadcrumb datasource=#REQUEST.theDatabase# !---SELECT the values for the Deleted level into variables--- DECLARE DeletedAreaName VARCHAR(50); DECLARE DeletedLft INTEGER; DECLARE DeletedRgt INTEGER; SELECT SiteAreaName, Lft, Rgt INTO DeletedAreaName, DeletedLft, DeletedRgt FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#'; !---Perform the deletion--- DELETE FROM directoryLinks WHERE Lft BETWEEN DeletedLft AND DeletedRgt; !---UPDATE the table so that the gaps between Lft and Rgt values are removed--- UPDATE directoryLinks SET Lft = CASE WHEN Lft DeletedLft THEN Lft - (DeletedRgt - DeletedLft + 1) ELSE Lft END, Rgt = CASE WHEN Rgt DeletedLft THEN Rgt - (DeletedRgt - DeletedLft + 1) ELSE Rgt END WHERE Lft DeletedLft OR Rgt DeletedLft; /cfquery [/code] NB. Forgot to previously mention thatI'm using MX 7 SQL server 2000 ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:244618 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: CF Declaring SQL variables
Assuming you're using MS-SQL (not sure about other DBs), and assuming you're only trying to 'get' the data into the variables: Your variable should start with an '@'. DECLARE @DeletedAreaName VARCHAR(50); DECLARE @DeletedLft INTEGER; DECLARE @DeletedRgt INTEGER; SELECT TOP 1 @DeletedAreaName = SiteAreaName, @DeletedLft = Lft, @DeletedRgt = Rgt FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#' Oh and I'd use cfqueryparam, but you may have stripped that for the sake of brevity.

Re: CF Declaring SQL variables
Hi Auke, I think this would have worked but I'm getting a CURSOR error: 'VARCHAR' is not a recognized CURSOR option. I've come across this error a few times before and don't really understand it and the way to fix it. Any ideas.

Re: CF Declaring SQL variables
Auke's code is working fine for me: DECLARE @MyVar VARCHAR( 3 ); SELECT TOP 1 @MyVar = game_sTeamA FROMtbl_game WHERE game_nID = 1 ; SELECT @MyVar Result: | (No Column Name) --+--- 1 | GER Mingo.

Hi Auke, I think this would have worked but I'm getting a CURSOR error: 'VARCHAR' is not a recognized CURSOR option. I've come across this error a few times before and don't really understand it and the way to fix it. Any ideas. I think only CURSORs are allowed names without a leading '@'. Most likely you are declaring your variables like this: DECLARE DeletedAreaName VARCHAR(50); instead of DECLARE @DeletedAreaName VARCHAR(50); Because (I think) you are declaring the variable without the starting '@', MS-SQL assumes it's a cursor, and therefore complains about the VARCHAR that follows it. ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:244625 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Re: CF Declaring SQL variables
Hi All, Tried both combinations of both way but couldn't get it to work. In the end I had to break it into multiple queries. [code] !--- GET Delete --- cfquery name=breadcrumb1 datasource=#REQUEST.theDatabase# !---SELECT the values for the Deleted level into variables--- SELECT SiteAreaName, Lft, Rgt FROM directoryLinks WHERE SiteAreaName = '#ARGUMENTS.SiteAreaName#' /cfquery cfset DeletedAreaName = '#breadcrumb1.SiteAreaName#' cfset DeletedLft = '#breadcrumb1.Lft#' cfset DeletedRgt = '#breadcrumb1.Rgt#' !--- Delete --- cfquery name=breadcrumb2 datasource=#REQUEST.theDatabase# !---Perform the deletion--- DELETE FROM directoryLinks WHERE Lft BETWEEN cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / AND cfqueryparam value=#DeletedRgt# cfsqltype=cf_sql_integer /; /cfquery !---UPDATE the table so that the gaps between Lft and Rgt values are removed--- !--- GET Delete --- cfquery name=breadcrumb3 datasource=#REQUEST.theDatabase# UPDATE directoryLinks SET Lft = (CASE WHEN Lft cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / THEN Lft - (cfqueryparam value=#DeletedRgt# cfsqltype=cf_sql_integer / - cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / + 1) ELSE Lft END), Rgt = (CASE WHEN Rgt cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / THEN Rgt - (cfqueryparam value=#DeletedRgt# cfsqltype=cf_sql_integer / - cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / + 1) ELSE Rgt END) WHERE Lft cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / OR Rgt cfqueryparam value=#DeletedLft# cfsqltype=cf_sql_integer / /cfquery [/code] Thanks for all you help.
