Example
In the "Sales Item Detail" table (pub.demo.retail.item), you can find only those rows whose SKUs start with either "96" or "3B". To do this, create a computed column and apply thebeginswith(X;L) function to the
sku column, where L is the list containing the strings
'96' and
'3B':<base table="pub.demo.retail.item"/> <willbe name="example" value="beginswith(sku;'96' '3B')"/>
For
those values in the sku column that begin with "96"
or "3B", the result is
1.
Otherwise, the result is 0.
You could then use the <sel> operation
to select only those rows where the example column equals
1.
<sel value="(example=1)"/>
The
results are those rows where the value in the sku column is
3B7, 969, or
96A.
