I am working on a poll which allows multiple selections.
How do I get this strored procedure to work? I am passing null values from
the <cfstoredproc> tag and want to conditionally run a query depending n
whether the value of the variable is NULL or not. I have tried <> NULL, NOT
NULL, !=. With <> nothing happens, and with NOT NULL and != I get syntax
errors.
--------------------------------------------------------------------
CREATE PROCEDURE spMyVote (@PollID VARCHAR(25), @PollType CHAR(3), @ChoiceA
CHAR(1), @ChoiceB CHAR(1), @ChoiceC (1))
AS
IF @PollType = 'MS'
BEGIN
IF @ChoiceA <> NULL
BEGIN
UPDATE PollMultipleChoice
SET AVote = AVote + 1
WHERE PollID = @PollID
END
IF @ChoiceB <> NULL
BEGIN
UPDATE PollMultipleChoice
SET BVote = BVote + 1
WHERE PollID = @PollID
END
IF @ChoiceC <> NULL
BEGIN
UPDATE PollMultipleChoice
SET CVote = CVote + 1
WHERE PollID = @PollID
END
END
----------------------------------------------------
Here is the stored procedure tag:
<cfstoredproc procedure="spMyVote"
datasource="arica">
<cfprocparam type="In"
cfsqltype="CF_SQL_VARCHAR"
dbvarname="@PollID"
value="#TRIM(FORM.PollID)#">
<cfprocparam type="In"
cfsqltype="CF_SQL_CHAR"
dbvarname="@PollType"
value="#TRIM(FORM.PollType)#">
<cfprocparam type="In"
cfsqltype="CF_SQL_CHAR"
dbvarname="@ChoiceA"
value="#Trim(FORM.ChoiceA)#"
null="#IIf(FORM.ChoiceA IS '', 1, 0)#">
<cfprocparam type="In"
cfsqltype="CF_SQL_CHAR"
dbvarname="@ChoiceB"
value="#Trim(FORM.ChoiceB)#"
null="#IIf(FORM.ChoiceB IS '', 1, 0)#">
<cfprocparam type="In"
cfsqltype="CF_SQL_CHAR"
dbvarname="@ChoiceC"
value="#Trim(FORM.ChoiceC)#"
null="#IIf(FORM.ChoiceC IS '', 1, 0)#">
</cfstoredproc>
