I have two different set of columns in my cfquery. One set of columns is reserved for the values and second is reserved for title in the form input fields. I'm building structure on the server side and I would like these two in separate columns. Here is example:
<cfquery name="UInfo" datasource="Test">
SELECT TOP 1
u_fname,
u_lname,
zu_fname,
zu_lname
FROM Users WITH (NOLOCK)
WHERE u_urid = '0012341'
</cfquery>
<cfloop query="UInfo">
<cfset qryRecs = StructNew()>
<cfloop array="#UInfo.getColumnNames()#" index="columnName">
<cfset qryRecs[columnName]['value'] = UInfo[columnName][CurrentRow]>
<cfset qryRecs[columnName]['title'] = (structKeyExists(UInfo, "z"&columnName)? UInfo[columnName][CurrentRow] : "")>
</cfloop>
</cfloop>
My code above will produce this kind of output:
U_FNAME
struct
title First Time
value Mark
U_FLAST
struct
title New Customer
value Miller
ZU_FNAME
struct
title First Time
value [empty string]
ZU_LNAME
struct
title New Customer
value [empty string]
As you can see above my code produced structure for Z columns as well. I don't need separate structure for these columns they should show in TITLE only. My output should be something like this:
U_FNAME
struct
title First Time
value Mark
U_FLAST
struct
title New Customer
value Miller
I'm not sure how to get desired output. If anyone can help please elt me know. Thank you!
Appears you simply need an if statement on the columnName inside the column names loop
<cfif left(columnName, 1) eq "u">
You have this:
<cfset qryRecs = StructNew()>
inside a loop. It should be before this:
<cfloop query="UInfo">

I need to provide some status on items in my table which I do in the last column of my table.
First I go and query one table to see if I have a confirmation for the item .
<cfquery name="focnotice" datasource="******" result="FocResult">
SELECT ecspc
FROM tbl_CNR_H
WHERE icsc = '#myarray[i].ICSC#'
AND asr_no = '#myarray[i].ASR#'
</cfquery>
The ECSPC is a field in my Table, so logic is see if there is a record. If so, see if the ECSPC value is something other then "". If so, query another table to see if there is a matching record for this ECSPC.
<cfset ISUPStatus = "#focnotice.ecspc#">
<cfif ISUPStatus NEQ "">
<cfquery name="isupStatus" datasource="******" result="ISUPResult">
select *
from tbl_ISUP
where dpc = '#ISUPStatus#'
</cfquery>
<cfset isupcount = #ISUPResult.RecordCount#>
<cfif #isupcount# GT 0>
<cfset ISUPorder = "Yes">
<cfelse>
<cfset ISUPorder = "No">
</cfif>
<cfelse>
<cfset ISUPorder = "No">
</cfif>
I get the following error in my debug
Complex object types cannot be converted to simple values.
The expression has requested a variable or an intermediate expression
result as a simple value. However, the result cannot be converted to a
simple value. Simple values are strings, numbers, boolean values, and
date/time values. Queries, arrays, and COM objects are examples of
complex values. The most likely cause of the error is that you tried
to use a complex value as a simple one. For example, you tried to use
a query variable in a cfif tag.
What am I missing here ?
You are passing invalid parameter into the Query "myarray[i].ICSC",'#myarray[i].ASR#'. You need to specify what index of array you are using.
<cfquery name="focnotice" datasource="*******" result="FocResult">
Select ecspc
From tbl_CNR_H
Where icsc = <cfqueryparam cfsqltype="cf_sql_varchar" value="#myarray[1].ICSC#">
AND
asr_no = <cfqueryparam cfsqltype="cf_sql_varchar" value="#myarray[1].ASR#">
</cfquery>
I believe the error causing you the issue lies in:
<cfset isupcount = #ISUPResult.RecordCount#>
From a quick look of your code, try using instead:
<cfset isUpCount = isUpStatus.recordCount>
But in addition please look at the comments above, especially joins.
I have a query result set from cfquery. I just want to add a new after a particular row number. But When tried each time it inserts the row at the end.
Is there any way I can insert row at the middle of the query?
<cfquery datasource="cse" name="abc">
select * from grade
</cfquery>
<cfset i = 0>
<cfloop query="abc">
<cfset i = i+1>
<cfif i eq 2>
<cfset queryAddRow(abc)>
</cfif>
</cfloop>
You cannot, easily. You have a coupla options.
<cfquery name="resultSet" dbtype="query">
SELECT col1, col2, etc
FROM yourQuery
WHERE [somecondition matching the "top" rows]
UNION
SELECT 'value' AS col1, 'value' AS col2, etc
UNION
SELECT col1, col2, etc
FROM yourQuery
WHERE [somecondition matching the "bottom" rows]
</cfquery>
Or you could simply loop over the original query, building a new query, using queryNew(), queryAddRow() and querySetCell(). At the appropriate point in the loop... add the row you want to insert, then continue adding the rest of them.
There's no elegant way I can think of.
Not knowing the goal you are trying to accomplish, my first advice would be along the lines of the other answers. Add rows that you can subsequently sort using Order By. However, if you really just want to inject a row at a specific position in the existing query, this should do it for you. Note you'll need to define the columns in the QueryNew(), so I've provided a sample case.
<cfquery datasource="cse" name="abc">
select student, teacher from grade
</cfquery>
<cfset abc_new = QueryNew("student,teacher","varchar,varchar")>
<cfloop query="abc">
<!--- ADD NEW DATA TO QUERY AT ROW 2 --->
<cfif CURRENTROW eq 2>
<cfset QueryAddRow(abc_new) />
<cfset QuerySetCell(abc_new,"STUDENT","Tommy Oliver") />
<cfset QuerySetCell(abc_new,"TEACHER","Ms. Appleby") />
</cfif>
<!--- COPY ORIGINAL DATA TO QUERY, ROW NUMBERS NOT PRESERVED --->
<cfset QueryAddRow(abc_new) />
<cfset QuerySetCell(abc_new,"STUDENT",abc.STUDENT) />
<cfset QuerySetCell(abc_new,"TEACHER",abc.TEACHER) />
</cfloop>
<cfdump var="#abc_new#">
The best way would be to create a new query, copying each row from the original but adding the new row at the required point.
Use QueryNew( ) to create the new query.
A bit like copying text files line-by-line and inserting a new line in the middle!
Again, not quite sure you'd need to do this - you could simply add a sortorder column, incrementing in 10s for each row. The new row would then have a sortorder in between the row before and the row after. eg sortorder would be 15 to insert between 10 and 20.
Hope this helps!
I assume row positions in your recordset are based on what you ORDER BY'd in your initial CFQUERY.
Therefore, I'd add the row to the recordset, then do a query of that recordset (query of query) using the same ORDER BY as the initial query, which should then return all rows including your new one, in the (presumed) proper order, in a new recordset.

I was using this line to get the MIN value of a query column. I just noticed a null value in a recordset causes an error. Is there a simply way to tell ArrayMin to skip nulls w/o having to loop the column and load an array with all non-null values?
<cfset temp_data_min = #round(ArrayMin(query_x["some_field"]))#>
thanks!
Building off of what Al said with using the query-of-queries, just adding the Min() call into the query.
<cfquery name="query_x_fixed" dbtype="query">
SELECT Min(some_field) as some_field
FROM query_x
WHERE some_field IS NOT NULL
</cfquery>
<cfset temp_data_min = round(query_x_fixed.some_field)>
Tested to work in CF9
You could loop through your array and create a new array that doesn't contain any null values. Then apply the ArrayMin function to the new array.
<cfset newArray = []>
<cfloop index="x" array="#query_x["some_field"]#">
<cfif x NEQ 'null'>
<cfset arrayAppend(newArray, x)>
</cfif>
</cfloop>
<cfset temp_data_min = round(ArrayMin(newArray))>
NOT TESTED
Simplest way is probably to do a query-of-queries with just that column and remove the nulls.
<cfquery name="query_x_fixed" dbtype="query">
SELECT some_field
FROM query_x
WHERE some_field IS NOT NULL
</cfquery>
<cfset temp_data_min= round(ArrayMin(query_x_fixed["some_field"]))>
(not tested)
You can keep the solution at one line by converting the column to a list then into an array. ListToArray defaults to ignoring empty list items, which is what the null values will be.
<cfset temp_data_min = Round(ArrayMin(ListToArray(ValueList(query_x.some_field, Chr(7)), Chr(7))))>
This should be faster than any of the other proposed solutions and is less code.
I've specified the delimiter for locales that use the comma as the decimal separator in numbers. If you're in the US or another locale that uses the "." then you can remove the delimiter arguments.
Additional functions used:
ListToArray
ValueList
Chr
I’ve mostly only used coldfusion for queries before never needed structs or any object notation until now. The server I am working on doesn’t have debugging turned on just a “500- internal server error.” so I am unable to see why my code is not working and sadly I do not have the ability to turn debugging on.
By trial and error with commenting blocks out I’ve noticed the errors are occurring in my struct line, and adding the struct to my array. From what I’ve read of the CF documentation I do not see any syntax errors but any help would be much appreciated as to if I have any bad logic or what could be wrong.
<cfset dataArray = []>
<cfset i = 0>
<cfloop query="getMembers">
<cfquery name="getmaps" datasource=“a" dbtype="odbc">
SELECT member_id, mlong, mlat
FROM maps
WHERE member_id = '#getMembers.MemberID#'
</cfquery>
<cfif getmaps.recordcount eq 1>
<!--- temp structure to insert into array --->
<cfset dataTemp = {
memberID = getMemebers.memberID,
name = getMemebers.MemberName,
long = getmaps.mlong,
lat = getmaps.mlat
}>
<cfset dataArray[i] = dataTemp>
<cfset i++>
</cfif>
</cfloop>
I addition to Shawn's comment, I believe you'll have a problem with starting your array index at 0, rather than 1. Coldfusion begins array indices at 1.
edit Some more suggestions:
<cfset dataArray = []>
<cfloop query="getMembers">
<!--- Not usually a good idea to query each time through a loop - should be able to do a single query outside it --->
<cfquery name="getmaps" datasource=“a" dbtype="odbc">
SELECT member_id, mlong, mlat
FROM maps
WHERE member_id = <cfqueryparam value='#getMembers.MemberID#' cfsqltype="cf_sql_varchar"><!--- assuming varchar since you had quotes around it --->
</cfquery>
<cfif getmaps.recordcount eq 1>
<!--- temp structure to insert into array --->
<cfset dataTemp = {
memberID = getMembers.memberID,
name = getMembers.MemberName,
long = getmaps.mlong,
lat = getmaps.mlat
}>
<cfset ArrayAppend(dataArray,dataTemp)>
</cfif>
</cfloop>
You should consider combining the two queries into one query.
<cfquery name="qryMemberMaps" datasource="a" dbtype="ODBC">
SELECT
members.memberID, members.MemberName,
maps.mlong, maps.mlat
FROM
[members_database].dbo.members JOIN [maps_database].dbo.maps ON members.memberID = maps.member_id
</cfquery>
The current method could potentially generate thousands of queries when you only need one!
Anytime you find yourself looping over a query and calling other queries, it is a good idea to revise the original query and save hammering your database server.
For putting the data into an array of structs, Jake's answer works well.
If you are joining multiple DB's make sure that you create a non-clustered index on the column(s) that will act as the primary/foreign keys.
I'm trying to create a function to create csv files from queries. After I run the query, I'm looping through it and appending each row's fields to a StringBuffer object. To that end, I'm putting the column names into an array:
<cfset indexes = #ListToArray(Arguments.header)# />
where the argument is currently a string like:
"col1, col2, col3...."
I've verified that both the query and the array are what they should be by dumping.
The trouble comes when looping through the query results. Given:
<cfset indexes_length = #ArrayLen(indexes)# />
<cfloop query="query_for_csv">
<cfloop index="i" from="1" to="#indexes_length#">
<cfset attr = #indexes[i]# />
<cfset sbOutput.Append(
"#query_for_csv[attr][query_for_csv.CurrentRow]#") />
</cfloop>
</cfloop>
Only the first value of the first row is output before I get the error message:
[Table (rows 10 columns col1, col2, col3):
[col1: coldfusion.sql.QueryColumn#6f731eba]
[col2: coldfusion.sql.QueryColumn#6ee67e7f]
[col3: coldfusion.sql.QueryColumn#5c6647cb]
is not indexable by col2
If I replace the variable #attr# with the literal "col2":
#query_for_csv['col2'][query_for_csv.CurrentRow]#
then the loop sails through with no problem, and spits out all the values indexed by 'col2'. Any ideas?
I would guess it's the spaces in your header list that is the problem, so probably this would work:
<cfset attr = trim(indexes[i]) />
However, since you're not using them, you probably don't need that and can just do this...
<cfloop query="QueryName">
<cfloop index="CurCol" list=#QueryName.ColumnList# >
<cfset sbOutput.Append(
QueryName[CurCol][QueryName.CurrentRow]
)/>
</cfloop>
</cfloop>
p.s.
You'll note here that there's only one pair of hashes - there only needs to be one pair in your original code snippets too (in the to attribute) - the rest are unnecessary noise.
As has already been said before, try to avoid spaces before or after a list element.
