Description

Adds a specified number of empty rows to a query. The function accepts either number of rows or any data structure (struct, arrays or structs, arrays of arrays).

Returns

The number of rows in the query

Function syntax

QueryAddRow(query [, number])

QueryAddRow(query [, number])

QueryAddRow(query [, data])

QueryAddRow(query [, data])

Parameters

Parameter	Description
query	Name of an executed query.
number	Number of rows to add to the query. The default value is 1.

Usage

As previously mentioned, ColdFusion lets you specify a struct, an array of structs, or arrays with single or multiple dimensions to add rows to the query as shown in the following example:

queryAddRow(myQuery1,

[

{id=2,name="Two"},

{id=3,name="Three"},

{id=4,name="Four"}

]);

queryAddRow(myQuery2,{id=4,name="Four"});

queryAddRow(myQuery1,

[

[1,"One"],

[2,"Two"],

[3,"Three"]

]);

queryAddRow(myQuery1, [ {id=2,name="Two"}, {id=3,name="Three"}, {id=4,name="Four"} ]); queryAddRow(myQuery2,{id=4,name="Four"}); queryAddRow(myQuery1, [ [1,"One"], [2,"Two"], [3,"Three"] ]);

queryAddRow(myQuery1, 
[ 
{id=2,name="Two"}, 
{id=3,name="Three"}, 
{id=4,name="Four"} 
]); 
queryAddRow(myQuery2,{id=4,name="Four"});



queryAddRow(myQuery1, 
[ 
[1,"One"], 
[2,"Two"], 
[3,"Three"] 
]);

Example

<h3>QueryAddRow Example</h3>

SELECT Course_ID, Number, Descript

FROM Courses

</cfquery>

<p>The Query "GetCourses" has <cfoutput>#GetCourses.RecordCount#</cfoutput> rows.

<cfset Temp = QuerySetCell(GetCourses, "Descript",

"Description of variable #Countvar#")>

</cfloop>

<P>After the QueryAddRow action, the query has <CFOUTPUT>#GetCourses.RecordCount#</CFOUTPUT>

records.

<PRE>#Course_ID# #Number# #Descript#</pre>

</cfoutput>

<h3>QueryAddRow Example</h3>  <cfquery name = "GetCourses" datasource = "cfdocexamples"> SELECT Course_ID, Number, Descript FROM Courses </cfquery> <p>The Query "GetCourses" has <cfoutput>#GetCourses.RecordCount#</cfoutput> rows. <cfset CountVar = 0> <cfloop CONDITION = "CountVar LT 15"> <cfset temp = QueryAddRow(GetCourses)> <cfset CountVar = CountVar + 1> <cfset Temp = QuerySetCell(GetCourses, "Number", 100*CountVar)> <cfset Temp = QuerySetCell(GetCourses, "Descript", "Description of variable #Countvar#")> </cfloop> <P>After the QueryAddRow action, the query has <CFOUTPUT>#GetCourses.RecordCount#</CFOUTPUT> records. <CFOUTPUT query="GetCourses"> <PRE>#Course_ID# #Number# #Descript#</pre> </cfoutput>

<h3>QueryAddRow Example</h3> 

<!--- start by making a query ---> 
<cfquery name = "GetCourses" datasource = "cfdocexamples"> 
SELECT Course_ID, Number, Descript 
FROM Courses 
</cfquery> 

<p>The Query "GetCourses" has <cfoutput>#GetCourses.RecordCount#</cfoutput> rows. 

<cfset CountVar = 0> 
<cfloop CONDITION = "CountVar LT 15"> 
<cfset temp = QueryAddRow(GetCourses)> 
<cfset CountVar = CountVar + 1> 
<cfset Temp = QuerySetCell(GetCourses, "Number", 100*CountVar)> 
<cfset Temp = QuerySetCell(GetCourses, "Descript", 
"Description of variable #Countvar#")> 
</cfloop> 

<P>After the QueryAddRow action, the query has <CFOUTPUT>#GetCourses.RecordCount#</CFOUTPUT> 
records. 
<CFOUTPUT query="GetCourses"> 
<PRE>#Course_ID# #Number# #Descript#</pre> 
</cfoutput>

Example

The following example first creates an empty recordset. Then it creates a struct with key-value pairs that represent rows in the query recordset. Finally the rows are populated with the struct data.

myTeam=QueryNew("Jersey,Player_Name,Matches_Played","integer,varchar,integer"); //Create empty recordset myTeam

//Display query headers

WriteOutput("Empty query recordset:");

WriteDump(myTeam);

/*Now add rows and populate rows with data. Create a struct with data*/

RealMadrid=StructNew();

RealMadrid={Jersey=1,Player_Name="Keylor Navas",Matches_Played=50};

QueryAddRow(myTeam,RealMadrid);

//Add more data to Real Madrid

RealMadrid={Jersey=7,Player_Name="Cristiano Ronaldo",Matches_Played=75};

//Add the updated struct as data in myTeam

QueryAddRow(myTeam,RealMadrid);

WriteOutput("Record with rows added:");

WriteDump(myTeam);

</cfscript>

<cfscript> myTeam=QueryNew("Jersey,Player_Name,Matches_Played","integer,varchar,integer"); //Create empty recordset myTeam //Display query headers WriteOutput("Empty query recordset:"); WriteDump(myTeam); /*Now add rows and populate rows with data. Create a struct with data*/ RealMadrid=StructNew(); RealMadrid={Jersey=1,Player_Name="Keylor Navas",Matches_Played=50}; QueryAddRow(myTeam,RealMadrid); //Add more data to Real Madrid RealMadrid={Jersey=7,Player_Name="Cristiano Ronaldo",Matches_Played=75}; //Add the updated struct as data in myTeam QueryAddRow(myTeam,RealMadrid); WriteOutput("Record with rows added:"); WriteDump(myTeam); </cfscript>

<cfscript>
       myTeam=QueryNew("Jersey,Player_Name,Matches_Played","integer,varchar,integer"); //Create empty recordset myTeam
       //Display query headers
       WriteOutput("Empty query recordset:");
       WriteDump(myTeam);
       /*Now add rows and populate rows with data. Create a struct with data*/
       RealMadrid=StructNew();
       RealMadrid={Jersey=1,Player_Name="Keylor Navas",Matches_Played=50};
       QueryAddRow(myTeam,RealMadrid);
       //Add more data to Real Madrid
       RealMadrid={Jersey=7,Player_Name="Cristiano Ronaldo",Matches_Played=75};
       //Add the updated struct as data in myTeam
       QueryAddRow(myTeam,RealMadrid);
       WriteOutput("Record with rows added:");
       WriteDump(myTeam);
</cfscript>

Output

Using member function

The member function returns the updated query, not the number of rows as per the function version.

myQuery=QueryNew("ID, Name, Age","integer,varchar,integer");

// Add rows and populate rows with struct data

people=StructNew();

people={ID=50,Name="John Doe",Age=30};

added=QueryAddRow(myquery,people)

writeOutput(added) // Returns 1

//break;

peopleAnother={ID=51,Name="Jane Doe",Age=32};

myQuery.addRow(peopleAnother);

WriteDump(myQuery);

</cfscript>

<cfscript> myQuery=QueryNew("ID, Name, Age","integer,varchar,integer"); // Add rows and populate rows with struct data people=StructNew(); people={ID=50,Name="John Doe",Age=30}; added=QueryAddRow(myquery,people) writeOutput(added) // Returns 1 //break; peopleAnother={ID=51,Name="Jane Doe",Age=32}; myQuery.addRow(peopleAnother); WriteDump(myQuery); </cfscript>

<cfscript>
       myQuery=QueryNew("ID, Name, Age","integer,varchar,integer");
       // Add rows and populate rows with struct data
       people=StructNew();
       people={ID=50,Name="John Doe",Age=30};
       added=QueryAddRow(myquery,people)
       writeOutput(added) // Returns 1
       //break;
       peopleAnother={ID=51,Name="Jane Doe",Age=32};
       myQuery.addRow(peopleAnother);
       WriteDump(myQuery);
