My Foolish Question

Question

Hi People I am using a cfffunction and returntype is array.
I am using on my cfm page and try to get the values i am
getting error:
<cfinvoke component="showall" method="getDBTableStruct"
tablename="#url.table#" returnvariable="tableData"/>
<cfdump var="#tableData#">
<cfset wibble = getDBTableStruct() />
<cfoutput>#wibble[ColumnName]#</cfoutput>
</cfif>
The web site you are accessing has experienced an unexpected

The error occurred in C:\Inetpub\wwwroot\p1\index.cfm: line

115 : <cfinvoke component="showall"
method="getDBTableStruct" tablename="#url.table#"

117 : <cfset wibble = getDBTableStruct() />
118 : <cfoutput>#wibble[ColumnName]#</cfoutput>
119 : </cfif>
Ok When I Dump i get The Following:
array
1
struct
AllowNulls false
CF_DataType CF_SQL_INTEGER
ColumnName ban_id
Increment true
PrimaryKey true
Special [empty string]
2
struct
AllowNulls true
CF_DataType CF_SQL_VARCHAR
ColumnName ban_title
Increment false
PrimaryKey false
Special [empty string]
length 255
3
struct
AllowNulls true
CF_DataType CF_SQL_VARCHAR
ColumnName ban_img
Increment false
PrimaryKey false
Special [empty string]
length 255
4
struct
AllowNulls true
CF_DataType CF_SQL_LONGVARCHAR
ColumnName ban_link
Increment false
PrimaryKey false
Special [empty string]
5
struct
AllowNulls true
CF_DataType CF_SQL_INTEGER
ColumnName ban_hits
Increment false
PrimaryKey false
Special [empty string]
6
struct
AllowNulls true

Ok My CFC is returning this:
<cffunction name="getDBTableStruct" access="public"
returntype="array" output="no" hint="I return the structure of the
given table in the database.">
<cfargument name="tablename" type="string"
required="yes">
<cfscript>
var qRawFetch = 0;
var arrStructure = 0;
var tmpStruct = StructNew();
var i = 0;
var PrimaryKeys = 0;
var TableData = ArrayNew(1);
</cfscript>
<cfset qRawFetch = runSQL("SELECT TOP 1 * FROM
#arguments.tablename#")>
<cfset arrStructure = getMetaData(qRawFetch)>
<cfif isArray(arrStructure)>
<cfloop index="i" from="1" to="#ArrayLen(arrStructure)#"
step="1">
<cfset tmpStruct = StructNew()>
<cfset tmpStruct["ColumnName"] = arrStructure
.Name>
<cfset tmpStruct["CF_DataType"] =
getCFDataType(arrStructure.TypeName)>
<!--- %% Ugly guess --->
<cfif arrStructure
.TypeName eq "COUNTER" OR ( i eq 1 AND arrStructure.TypeName
eq "INT" AND Right(arrStructure
.Name,2) eq "ID" )>
<cfset tmpStruct["PrimaryKey"] = true>
<cfset tmpStruct["Increment"] = true>
<cfset tmpStruct["AllowNulls"] = false>
<cfelse>
<cfset tmpStruct["PrimaryKey"] = false>
<cfset tmpStruct["Increment"] = false>
<cfset tmpStruct["AllowNulls"] = true>
</cfif>
<!--- %% Ugly guess --->
<cfif isStringType(arrStructure.TypeName) AND NOT
tmpStruct["CF_DataType"] eq "CF_SQL_LONGVARCHAR">
<cfset tmpStruct["length"] = 255>
</cfif>
<cfset tmpStruct["Special"] = "">
<cfif Len(tmpStruct.CF_DataType)>
<cfset ArrayAppend(TableData,StructCopy(tmpStruct))>
</cfif>
</cfloop>
<cfelse>
<cfthrow message="Error Found."

<cfreturn TableData>
</cffunction>
