CFML - query row to structure - coldfusion

Question

I would like to handle a row from a query by a function, where I pass the row as a structure.
ideally...
<cfloop query="myquery">
#myfunction(#row#)#
</cfloop>
I could set it up like this too...
<cfloop query="myquery">
#myfunction(#col1#,#col2#,#col3#,#col4#)#
</cfloop>
but I don't want to. I haven't been able to finda simple way of extracting a row, But I thought I'd ask.

Answer 1

found a little more elegant looking solution, for single row
<cfscript>
function GetQueryRow(query, rowNumber) {
var i = 0;
var rowData = StructNew();
var cols = ListToArray(query.columnList);
for (i = 1; i lte ArrayLen(cols); i = i + 1) {
rowData[cols[i]] = query[cols[i]][rowNumber];
}
return rowData;
}
</cfscript>

Answer 2

Adobe ColdFusion 11 introduced QueryGetRow which converts a row from a query into a struct.

Answer 3

Ben Nadel has posted a blog post about this where he gives an example UDF that converts a query to a struct, and it accepts an optional row argument that allows you to turn an single row in that query to a struct. Take a look here.

<cffunction name="QueryToStruct" access="public" returntype="any" output="false"
hint="Converts an entire query or the given record to a struct. This might return a structure (single record) or an array of structures.">
<cfargument name="Query" type="query" required="true" />
<cfargument name="Row" type="numeric" required="false" default="0" />
<cfscript>
var LOCAL = StructNew();
if (ARGUMENTS.Row){
LOCAL.FromIndex = ARGUMENTS.Row;
LOCAL.ToIndex = ARGUMENTS.Row;
} else {
LOCAL.FromIndex = 1;
LOCAL.ToIndex = ARGUMENTS.Query.RecordCount;
}
LOCAL.Columns = ListToArray( ARGUMENTS.Query.ColumnList );
LOCAL.ColumnCount = ArrayLen( LOCAL.Columns );
LOCAL.DataArray = ArrayNew( 1 );
for (LOCAL.RowIndex = LOCAL.FromIndex ; LOCAL.RowIndex LTE LOCAL.ToIndex ; LOCAL.RowIndex = (LOCAL.RowIndex + 1)){
ArrayAppend( LOCAL.DataArray, StructNew() );
LOCAL.DataArrayIndex = ArrayLen( LOCAL.DataArray );
for (LOCAL.ColumnIndex = 1 ; LOCAL.ColumnIndex LTE LOCAL.ColumnCount ; LOCAL.ColumnIndex = (LOCAL.ColumnIndex + 1)){
LOCAL.ColumnName = LOCAL.Columns[ LOCAL.ColumnIndex ];
LOCAL.DataArray[ LOCAL.DataArrayIndex ][ LOCAL.ColumnName ] = ARGUMENTS.Query[ LOCAL.ColumnName ][ LOCAL.RowIndex ];
}
}
if (ARGUMENTS.Row){
return( LOCAL.DataArray[ 1 ] );
} else {
return( LOCAL.DataArray );
}
</cfscript>
</cffunction>
usage...
<!--- Convert the entire query to an array of structures. --->
<cfset arrGirls = QueryToStruct( qGirls ) />
<!--- Convert the second record to a structure. --->
<cfset objGirl = QueryToStruct( qGirls, 2 ) />

Answer 5

Another solution would be:
function QueryToStruct(query){
var cols = ListToArray(query.columnList);
var salida = query.map(function(v=0,i,a){
return {'#cols[1]#':v};
});
return ValueArray(salida,'#cols[1]#');
}
