oracle - Comparing outputs from 2 separate sql queries -

-

i trying write query inventory system. in order have count number of duplicates in 1 table , compare default quantity values taken table.

here 2 queries working currently: 

select template_id,  count(template_id) howmuch, t.name   consumables e, templates t  t.consumable_type_id = '2410980' group template_id, t.name having ( count(template_id) > 1 )

the query above takes account of each unique template id , gives me count of how many duplicates present tells me amount of single substance. 

   select        property_descriptors.default_value,        templates.name           templates,       property_descriptors           templates.consumable_type_id = '858190' ,       templates.audit_id = property_descriptors.audit_id ,       property_descriptors.name = 'reorder point'

this query finds amount of each individual substance have in our system.

my issue dont know of way compare results 2 queries.

ideally, want query give substance have duplicate count lower default value (found using query 2).

any ideas appreciated!

here table schema reference:

consumables

id|template_id|

templates

id|property_descriptor_id|name|audit_id

property_descriptors

id| name|default_value|audit_id

thanks!

    select  q1.name, q2.default_value - q1.howmuch           (select template_id, count(template_id) howmuch, t.name            consumables e, templates t             t.consumable_type_id = '2410980'            group template_id, t.name            having ( count(template_id) > 1 )) q1,           (select property_descriptors.default_value default_value,            templates.name  name                       templates,             property_descriptors                    templates.consumable_type_id = '858190' ,           templates.audit_id = property_descriptors.audit_id ,           property_descriptors.name = 'reorder point') q2          q1.name = q2.name

should trick you'll need clean result bit work away negative results or add q2.default_value - q1.howmuch > 0 in outer clause

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
