Remarks
If a layer or a standalonetable participates in a relationship, MapServer advertises that by populating those information as RelateInfo.
When there are more than one relationships exist between the same source and destination table(s) or layer(s), RelationshipID can be used to uniquely identify a relationship.
Example: Printing a list of all relates a layer or standalonetable is participating
Assuming pMTI is a MapTabeInfo passed in to this function
IRelateInfos pRIs = null;
IRelateInfo pRI = null;
pRIs = pMTI.RelateInfos;
if (pRIs == null)
{
Console.WriteLine(“No relationship is available”);
return;
}
for (int j = 0; j < pRIs.Count; j++)
{
pRI = pRIs.get_Element(j);
Console.WriteLine(pRI.Name + “, " + pRI.RelationshipID + “, ” + pRI.RelatedTableID + “\n”);
}
