Question

ColdFusion uses #‘s to delineate variables. In SQL Server a table name with # or ## is temp table and a global temp table respectively. How does one use SQL Temp tables in ColdFusion?

Answer 1

ColdFusion treats shows ## as a single # in the output. Hence

<cfquery name="qryTempUser">
SELECT * 
FROM   ##tempUsers
WHERE  Active_CODE = 1
</cfquery>

is pulling from a temp table called #tempUsers

<cfquery name="qryTempUser">
SELECT * 
FROM   ###myTableName#
WHERE  Active_CODE = 1
</cfquery>

is pulling from a temp table called that is specified in a ColdFusion variable called myTableName

<cfquery name="qryTempUser">
SELECT * 
FROM   ####tempUsers
WHERE  Active_CODE = 1
</cfquery>

is pulling from a global temp table called ##tempUsers

<cfquery name="qryTempUser">
SELECT * 
FROM   #####myTableName#
WHERE  Active_CODE = 1
</cfquery>

is pulling from a global temp table called that is specified in a ColdFusion variable called myTableName
