FlattenArrayBase (fab)
Purpose
Specifies the starting ordinal value appended to column names for flattened arrays. When
flattening arrays, column names are appended with an underscore and the ordinal
value (<array_name>_<ordinal_location>).
Valid Values
0 | 1
Behavior
If set to 0, the first column name in the array will be appended with an _0. For example, the first three columns
generated in the vehicles array would be the following in the Mixed relational view: VEHICLES_0, VEHICLES_1,
VEHICLES_2.
If set to 1, the first column name in the array will be appended with an _1. For example, the first three columns
generated in the vehicles array would be the following in the Mixed relational view: VEHICLES_1, VEHICLES_2,
VEHICLES_3.
