Custom Group Banding Size Method

Custom Group Banding Size Method is an advanced property that is hidden by default. For information on how to display this property, see Viewing and Changing Advanced VLDB Properties.

The Custom Group Banding Size Method helps optimize custom group banding when using the Size Banding method. You can choose to use the standard method that uses the Analytical Engine or database-specific syntax, or you can choose to use case statements or temp tables.

Examples

The following SQL examples were created in MicroStrategy Tutorial. The report contains a Custom Group "Customer Value Banding" that uses the size method and the Revenue metric. The SQL for each of the three settings for this property is presented below. All three options start with the same SQL passes. In this example, the first six passes are the same. The remaining SQL passes differ depending on the Custom Group Banding Count Method selected.

create table ZZMD000 (CUSTOMER_ID SHORT, WJXBFS1 DOUBLE)

insert into ZZMD000 

select a11.CUSTOMER_ID AS CUSTOMER_ID, a11.TOT_DOLLAR_SALES 

 as WJXBFS1

from CUSTOMER_SLS a11

create table ZZMD001 (WJXBFS1 DOUBLE)

insert into ZZMD001 

select sum(a11.TOT_DOLLAR_SALES) as WJXBFS1

from YR_CATEGORY_SLS a11

select pa1.CUSTOMER_ID AS CUSTOMER_ID,

 (pa1.WJXBFS1 / pa2.WJXBFS1) as WJXBFS1

from ZZMD000 pa1, ZZMD001 pa2

create table ZZMQ002 (CUSTOMER_ID SHORT, WJXBFS1 DOUBLE)

 [Placeholder for an Analytical SQL]

insert into ZZMQ02 values (DummyInsertValue)

Treat banding as normal calculation

select sum(a11.TOT_DOLLAR_SALES) as WJXBFS1

from CUSTOMER_SLS a11, ZZMQ002 a12

where a11.CUSTOMER_ID = a12.CUSTOMER_ID

select a12.DA57 AS DA57, sum(a11.TOT_DOLLAR_SALES) 

 as WJXBFS1

from CUSTOMER_SLS a11, ZZMQ002 a12

where a11.CUSTOMER_ID = a12.CUSTOMER_ID

group by a12.DA57

drop table ZZMD000

drop table ZZMD001

drop table ZZMQ002

Use standard CASE statement syntax

create table ZZOP003 (CUSTOMER_ID SHORT, DA57 LONG)

insert into ZZOP003 

select pa3.CUSTOMER_ID AS CUSTOMER_ID,

 (case 

 when (pa3.WJXBFS1 >= 0 and pa3.WJXBFS1 < .2) then 1

 when (pa3.WJXBFS1 >= .2 and pa3.WJXBFS1 < .4)then 2

 when (pa3.WJXBFS1 >= .4 and pa3.WJXBFS1 < .6)then 3

 when (pa3.WJXBFS1 >= .6 and pa3.WJXBFS1 < .8)then 4

 when (pa3.WJXBFS1 >= .8 and pa3.WJXBFS1 <= 1)then 5

 end) as DA57

from ZZMQ002 pa3

drop table ZZMD000

drop table ZZMD001

drop table ZZMQ002

drop table ZZOP003

Insert band range to database and join with metric value

create table ZZOP003 (BandNo LONG, BandStart DOUBLE, 

 BandEnd DOUBLE)

insert into ZZOP003 values (1, 0, .2)

[Insertions for other bands]

where ((pa3.WJXBFS1 >= pa4.BandStart

 and pa3.WJXBFS1 < pa4.BandEnd)

 or (pa3.WJXBFS1 = pa4.BandEnd

 and pa4.BandNo = 5))
