# Using Component Queries

## Using Component Queries

Component Queries allow a component template to **repeat once for each record returned by a SOQL query**.

Use them for:

* LineitemsSOQL
* Related lists

This avoids standard table layouts and gives full control over styling.

### Example 1: Repeating Opportunity Sections on an Account

**Use case:** Generate an Account document that includes a formatted section for each related Opportunity.

**Parent Template (Account)**

```html
<!--{{!
<LineItemsSOQL>
  <component>Opportunity Summary Component</component>
  <soql>
    SELECT Id 
    FROM Opportunity 
    WHERE AccountId='{{!Account.Id}}'
  </soql>
</LineItemsSOQL>
}}-->
```

This query:

* Retrieves all related Opportunities
* Inserts the component once per record

**Component Template (Opportunity)**

Template Format: **Component**

```html
<h3>{{!Opportunity.Name}}</h3>

<p>
  Stage: {{!Opportunity.StageName}}<br/>
  Amount: {{!Opportunity.Amount}}<br/>
  Close Date: {{!Opportunity.CloseDate}}
</p>
```

If the Account has three Opportunities, this component renders three times.

### Example 2: Scalable Queries Using Column Fields

**Use case:** Repeat a component for a large list of records while executing only **one SOQL query**.

**Parent Template**

```html
<!--{{!
<lineitemsSOQL>
  <class>none</class>
  <soql>
    SELECT Id, Name, StageName
    FROM Opportunity
    WHERE AccountId='{{!Account.Id}}'
  </soql>

  <component columnFields="true" mergeFieldPrefix="opp">
    Opportunity Summary Component
  </component>

  <column componentMergeField="true">Id</column>
  <column componentMergeField="true">Name</column>
  <column componentMergeField="true">StageName</column>
</lineitemsSOQL>
}}-->
```

**Component Template**

```html
<h3>{{!opp.Name}}</h3>
<p>Stage: {{!opp.StageName}}</p>
```

{% hint style="success" %}
Considerations for this method:

* Use `mergeFieldPrefix`
* Every merge field must be defined in a `<column>` tag
* Only one SOQL query runs, regardless of record count
  {% endhint %}
