go to post Vitaliy Serdtsev · Jun 30, 2022 parameter INDEXNULLMARKER; Override this parameter value to specify what value should be used as a null marker when a property of the type is used in a subscript of an index map. The default null marker used is -1E14, if none is specfied for the datatype. However %Library.PosixTime and %Library.BigInt datatypes could have values that collate before -1E14, and this means null values would not sort before all non-NULL values. For beauty, I would also use the value of this parameter, for example: Class dc.test Extends %Persistent { Property idp As dc.test; Property idpC As %Integer(INDEXNULLMARKER = "$c(0)") [ Calculated, Private, Required, SqlComputeCode = {s {*}=$s({idp}="":$c(0),1:{idp})}, SqlComputed ]; Property Name As %String [ Required ]; Index iUnq On (idpC, Name) [ Unique ]; ClassMethod Test() { d ..%KillExtent() &sql(insert into dc.test(Name,idp)values('n1',1)) w SQLCODE,! ;0 &sql(insert into dc.test(Name,idp)values('n2',1)) w SQLCODE,! ;0 &sql(insert into dc.test(Name,idp)values('n2',1)) w SQLCODE,!! ;-119 &sql(insert into dc.test(Name,idp)values('n1',null)) w SQLCODE,! ;0 &sql(insert into dc.test(Name,idp)values('n2',null)) w SQLCODE,! ;0 &sql(insert into dc.test(Name,idp)values('n2',null)) w SQLCODE,!! ;-119 zw ^dc.testD,^dc.testI } }Output: USER>d ##class(dc.test).Test() 0 0 -119 0 0 -119 ^dc.testD=4 ^dc.testD(1)=$lb("",1,"n1") ^dc.testD(2)=$lb("",1,"n2") ^dc.testD(3)=$lb("","","n1") ^dc.testD(4)=$lb("","","n2") ^dc.testI("iUnq",1," N1",1)="" ^dc.testI("iUnq",1," N2",2)="" ^dc.testI("iUnq",$c(0)," N1",3)="" ^dc.testI("iUnq",$c(0)," N2",4)=""Or Property idpC As %Integer [ Calculated, Private, Required, SqlComputeCode = {s {*}=$s({idp}="":$$$NULLSubscriptMarker,1:{idp})}, SqlComputed ];Output: USER>d ##class(dc.test).Test() 0 0 -119 0 0 -119 ^dc.testD=4 ^dc.testD(1)=$lb("",1,"n1") ^dc.testD(2)=$lb("",1,"n2") ^dc.testD(3)=$lb("","","n1") ^dc.testD(4)=$lb("","","n2") ^dc.testI("iUnq",-100000000000000," N1",3)="" ^dc.testI("iUnq",-100000000000000," N2",4)="" ^dc.testI("iUnq",1," N1",1)="" ^dc.testI("iUnq",1," N2",2)=""

go to post Vitaliy Serdtsev · Jun 30, 2022 The new version of IRIS 2022.2 has a new feature Columnar Storage, about which the documentation says the following: Choosing a storage layout is not an exact science. You might need to experiment with multiple layouts and run multiple query tests to find the optimal one. Therefore, you are unlikely to find an exact answer to your question. Usually, the more efficient the query is and there are "correct" indexes, the smaller the GREF and, accordingly, the shorter the execution time. But this is influenced by many factors, not just the above: see InterSystems SQL Optimization Guide

PS: for simplicity, I would advise you to create a clone of your dc.child class (without Relationship) and already take the "disappeared" data from it. After linking the tables (possibly with subsequent copying of data from the old Storage to the new one), the clone with the data can be deleted.
