# tableBelongsTo

##### Syntax

    void ADODB_Active_Record::TableBelongsTo(
      string $childTable,
      string $relationName,
      string $foreignKey,
      optional string $parentPrimaryKey = 'id',
      optional string $parentClass = 'ADODB_Active_Record'
      )

## Description

If the child table differs from the convention that the child table name is the plural of the child class name, use the function: tableBelongsTo();

## Parameters

### $childTable

The child table in the relationship

### $foreignKey

If, due to database design constraints, the key field in the child table is not named the same as that of the parent table, specify it here.

### $parentTable

The key field of the parent table in the relationship

### $foreignClass

If the class name for the child table differs from that of the parent, for example there has been some extension of methods, specify it here

## Usage

In this example the class is child, but the table name is children, and the link between the two tables is children.person_id = person.id

    ADODB_Active_Record::TableBelongsTo('children','person','person_id','id');
