Enterprise Architect - How to set column key to Autonum? - enterprise-architect

Question

I have a bunch of tables with Id int primary keys. However, I forgot to set AutoNum to True in the UI. Since changing all hundreds of tables is tedious, how can I set this property for all Id columns?
I have built a script that runs through each table and detects the Id column:
var package as EA.Package;
package = Repository.GetTreeSelectedPackage();
var tablesEnumerator = new Enumerator(package.Elements);
while (!tablesEnumerator.atEnd()) {
var table as EA.Element;
table = tablesEnumerator.item();
var methodsEnumerator = new Enumerator(table.Methods);
while (!methodsEnumerator.atEnd()) {
var method as EA.Method;
method = methodsEnumerator.item();
if (method.Name !== "Id") { continue; }
Session.Output(method.Name);
// Now what?!
}
}
I have searched for AutoNum in EnterpriseArchitect docs and APIs, but was unable to find suitable references.

According to Autonum in Column Properties inaccessible you can actually change the AutoNum behaviour via API with the means of TaggedValues. So there is no need of direct SQL updates to the database.
Setting the tagged values property and AutoNum on the Id attribute (not the method of the table seems to do the magic. It tried it via the builtin script engine and it works:

function main()
{
var package = Repository.GetTreeSelectedPackage();
var elements as EA.Collection;
elements = package.Elements;
Session.Output("Elements Count " + elements.Count);
for ( var ec = 0 ; ec < elements.Count ; ec++ )
{
var element as EA.Element;
element = elements.GetAt(ec);
if("Table" != element.MetaType) continue;
Session.Output("Element: Name '" + element.Name + "' [" + element.ElementGUID + "] '" + element.MetaType + "'.");
var attributes as EA.Collection;
attributes = element.Attributes;
for ( var ac = 0; ac < attributes.Count ; ac++)
{
var attribute as EA.Attribute;
attribute = attributes.GetAt(ac);
if("Id" != attribute.Name) continue;
Session.Output("Attribute: Name '" + attribute.Name + "' [" + attribute.AttributeGUID + "] in element '"+ element.Name + "' [" + element.MetaType + "].");
var hasTvProperty = false;
var hasTvAutonum = false;
var taggedValues as EA.Collection;
taggedValues = attribute.TaggedValues;
Session.Output("TaggedValues: Count " + taggedValues.Count);
for ( var tc = 0; tc < taggedValues.Count; tc++)
{
var taggedValue as EA.TaggedValue;
taggedValue = taggedValues.GetAt(tc);
if("property" != taggedValue.Name && "AutoNum" != taggedValue.Name) continue;
Session.Output("TaggedValue: Name '" + taggedValue.Name + "'. Value '" + taggedValue.Value + "'");
if("property" != taggedValue.Name)
{
taggedValue.Value = "AutoNum=1;StartNum=1;Increment=1;";
taggedValue.Update();
element.Update();
hasTvProperty = true;
}
if("AutoNum" != taggedValue.Name)
{
taggedValue.Value = "True";
taggedValue.Update();
element.Update();
hasTvAutonum = true;
}
}
if(!hasTvProperty)
{
var tv = taggedValues.AddNew("property", "AutoNum=1;StartNum=1;Increment=1;");
tv.Update();
element.Update();
}
if(!hasTvAutonum)
{
var tv = taggedValues.AddNew("AutoNum", "True");
tv.Update();
element.Update();
}
break;
}
}
}
