I am writing a query in ColdFusion 9.01 script and having trouble understanding why it is not caching the results. The same exact query will cache when executed using the CFML tag syntax.
The SQL, datasource, username, password are not changing. I have dumpped the cfscript query object after instantiating it and verified the cachedWithin argument was properly received during init. I'm stumped.
CFScript Version that will not cache
var Q = new Query(
SQL="SELECT * FROM TABLE"
,cachedwithin=createTimeSpan(0,0,60,0)
).execute().getResult();
CFML Tag Version that will cache
<cfquery name="local.q">SELECT * FROM TABLE</cfquery>
Thank you for your time and help.

Give it a name! :)
var Q = new Query(
SQL="SELECT * FROM TABLE"
,cachedwithin=createTimeSpan(0,0,60,0)
,name="myQuery"
).execute().getResult();

I cannot figure this out. My company recently upgraded our ColdFusion Server from CF9 to CF2021. One of my pages uses queries of queries to run. Prior to the upgrade the page worked fine. However after the upgrade the query of query where statement is not returning any results. Even though the original query has the data. The data is coming from DB2 data source in case that changed with the new version.
<cfquery name = "query_data_sample" dbtype="query">
SELECT
SAMPLE_DATE
, SAMPLE_NBR
, SAMPLE_MISC_NBR
, SUM (RECD_QTY) AS TTL_RECD_QTY
, SUM (MISC_QTY_1) AS TTL_MISC_QTY_1
, SUM ( 1 ) AS TTL_COUNT
FROM original_query_result
WHERE 1=1
AND SAMPLE_DATE = <cfqueryparam value = "#original_query_result.SAMPLE_DATE#" cfsqltype = "CF_SQL_DATE">
AND SAMPLE_NBR = <cfqueryparam value = "#trim(original_query_result.SAMPLE_NBR)#" cfsqltype = "CF_SQL_CHAR">
AND SAMPLE_MISC_NBR = <cfqueryparam value = "#trim(original_query_result.SAMPLE_MISC_NBR)#" cfsqltype = "CF_SQL_CHAR">
GROUP BY
SAMPLE_DATE
, SAMPLE_NBR
, SAMPLE_MISC_NBR
</cfquery>
When I comment out the AND statements and dump out the above query I can see the output of the original_query_result with all the TTL values and Sample rows. However if I want to grab just one row with the AND statements then the query comes back as not finding the row. I am doing a cfoutput query = original_query_result and trying to get the total quantity to display on each row in my output grid table.
Any help would be greatly appreciated. I have been trying to figure this out for more then a week now.
I saw something similar a while back and found this post:
https://web.archive.org/web/20180210052449/http://blog.dkferguson.com/index.cfm/2010/2/17/Using-Querie-of-Queries-with-CFDirectory
Basically I had to CAST the date and use cfqueryparam (as you are):
SAMPLE_DATE = CAST(<cfqueryparam value="#original_query_result.SAMPLE_DATE#" cfsqltype="CF_SQL_DATE"> AS date)
The post said they had to cast both sides but I didn't find this.
I am creating a new query object with
<cfset LOCAL.Query = QueryNew( "" ) />
I am then building up a complicated data set from an array that was passed in.
My query object looks perfect.
How do I then add the SQL text and datasource to the query so that I can execute it?
I am going to be inserting the data using a passed in datasource and insert statement.
If I'm understanding you correctly, in order to use SQL and retrieve data from your query object you will use CFQUERY. Instead of a 'datasource' attribute you will use 'dbtype="query"'. The table name of the query will be your query object. For example:
<cfquery dbtype="query" name="myQry">
SELECT * FROM LOCAL.Query
</cfquery>
You cannot add new records with an INSERT statement. You must use the function: QUERYADDROW() and, possibly, QUERYSETCELL().
For instance, :
<cfset queryAddRow(LOCAL.Query, {"id"=1,"title"="Hello world"})>
Or:
<cfset queryAddRow(LOCAL.Query)>
<cfset querySetCell(LOCAL.Query, "id", "1")>
<cfset querySetCell(LOCAL.Query, "title", "Hello world")>
Dan answered the question for me.
I was hoping to be able to modify the query object and add the datasource and SQL but after much study I was unable to do so.
The correct answer is Dan´s comment about a new query object.
I have a simple Query of Queries statement like this:
<cfquery name="rsProductTypeID" dbtype="query">
SELECT
ProductTypeID
FROM
rsProductTypes
WHERE
ProductType = <cfqueryparam value="Computers" cfsqltype="cf_sql_nvarchar"/>;
</cfquery>
All it is doing is asking for the primary key value (ProductTypeID) from the recordset rsProductType depending on which ProductType we are asking for.
For some reason the above query gives me this error:
PreparedStatement.setNString(int,java.lang.String)
But if I change the Query of Queries and remove the <cfqueryparam> part and replace it with normal text, then it works fine. Here is the working code:
<cfquery name="rsProductTypeID" dbtype="query">
SELECT
ProductTypeID
FROM
rsProductTypes
WHERE
ProductType = 'Computers';
</cfquery>
I can't tell what the difference is between the code that is causing it to fail when using <cfqueryparam> and not.
I think I figured it out... when ColdFusion returns a recordset, it doesn't maintain the original datatype from the database. In my database ProductType is defined as nvarchar(50) but ColdFusion returns it as varchar format. So the cfsqltype attribute was causing the error. I changed the cfsqltype attribute to cf_sql_varchar and it works fine. Very annoying but what can you do.
I posted it as a self-answer in case anyone else gets this error. Not sure if that's against the rules or not.
cf_sql_nvarchar is not a valid value for the cfsqltype attribute of cfqueryparam

I have a query where I am attempting to insert values into a table and one of these values (ImportID) is of type uniqueidentifier in the database. I have looked in the adobe CF documentation and saw that both cf_sql_char and cf_sql_idstamp should work for the cfquery param for my uniqueidentifier type. I also read this thread which says the same thing: What is the most appropriate Coldfusion cfsqltype to use for MS SQL's uniqueidentifier field type?
I have found a few other places that use the "maxlength" parameter for the cfqueryparam tag and cf_sql_char as the type but have not been able to make my code work. I keep getting an error along the lines of "Conversion failed when converting from a character string to uniqueidentifier." I'm including my code where I generate the UID and attempt the insert below (I replaced some of the variable names and took out all of the other columns for the import):
<cfscript>
ImportID = createUUID();
</cfscript>
<cfquery name="INSERTTableName" datasource="#Application.Datasource#">
INSERT INTO TableNameImport(
ImportID
)
VALUES(
<cfqueryparam value="#variables.ImportID#" cfsqltype="CF_SQL_CHAR">
)
</cfquery>
Any help would be greatly appreciated. Thanks in advance.
*********************************EDIT********************************
Found the answer:
<cfquery name="INSERTTableName" datasource="#Application.Datasource#">
DECLARE #ImportID uniqueidentifier
SET #ImportID = NEWID()
INSERT INTO TableNameImport(
ImportID
)
VALUES(
#ImportID
)
</cfquery>
The problem was that the UUID created from the coldfusion call is a different format from the one created in Microsoft SQL Server.
You are correct. SQL uses a GUID and createUUID manks a UUID. Both are 32hex value but use a differnt text format (location of dashes). And the use a different calculation to generate the random value. You can utilize UUID's if you change the text formating to have the GUID dash locations or send the binary value. For your example above that works you might also want return the GUID if cf needs a reference to that value.
I'm working with a query that has a column named "Date."
The original query returns okay from the database. You can output the original query, paginate the original query, get a ValueList of the Date column, etc.
Query of Query
<cfquery name= "Query" dbtype= "query">
select
[Query].[Date]
from [Query]
</cfquery>
Response from ColdFusion
Query Of Queries syntax error. Encountered "Date. Incorrect Select
List,
Typically, I use descriptive names so I haven't run across this issue previously.
In this case, I'm working with a stored procedure that someone else wrote. I ended up modifying the stored procedure to use a more descriptive column name.
I have a service I use for transforming, searching and sorting queries with ColdFusion. I'm curious to know the answer to my original question, so that I can modify my service to either throw a better error or handle reserved words.
Is there a way to escape and use ColdFusion query reserved words as column names in a query of query?
The following code works fine for me:
<cfset query = queryNew("date")>
<cfdump var="#query#">
<cfquery name= "Query" dbtype= "query">
select
[Query].[Date]
from [Query]
</cfquery>
<cfdump var="#query#">
In standard mysql you'd "escape" the fields by using the ` character.
So for example:
select `query`.`date` from `query`
Try that and see if it works?
