This document discusses Quick Query and Advanced Query, which are basic building blocks used in DMS forms to query data. Quick Query provides a basic search capability on common fields, while Advanced Query provides a separate window for more complex queries. Both utilize common packages and libraries to validate inputs and build SQL statements dynamically based on selected columns, operators, and other parameters. The document provides examples of how to implement query functionality using these shared components.

Introduction
 To understand how QQ and
Advance Query works in DMS.

What is Quick Query?
 Quick Query is a basic component
used in forms.
 The Quick Query is used on most
common fields in a given form.
 Quick Query is a standard option in
all our standard forms
development.
 User knows it as the flashlight
button.

5. 08/31/18 For a Better Future 5
What is Quick Query
Made of?
 The components has several parts
are:
 Packages: CMN_SQL_PKG
 PL/SQL Library:
CMN_L_TOOLBAR.pll
 Forms Program Unit:
DEV_TLBR_QUERY_RECORD_P
RE
 Used in all DMS forms for Quick
Query.

6. 08/31/18 For a Better Future 6
What is Advanced
Query?
 A separate window interface build to
support more advanced criteria option for
user to selected.
 The advanced query window has three
areas:
 Query parameters – users enter filter
information for the advanced query.
 Order result by - users can select the
columns that the query will be ordered by.
Maximum of 5.
 Results – Contains the result set.

7. 08/31/18 For a Better Future 7
What is Advanced Query
made of?
 The components has several parts
are:
 Packages: CMN_SQL_PKG
 PL/SQL Library:
CMN_L_TOOLBAR.pll
 Forms store procedure:
CMN_BLOCK_QUERY_(<Name>)
 Examples: Donor, Event, and B&C
Advanced Query.

How to Implement?
 Perform program validation of input fields
 Call VALIDATE_ITEM
 Initialize SQL creation field
 CMN_SQL_PKG. INIT_SQL_STMT_FIELDS
 Build where statement
 CMN_SQL_PKG.WHERE_STMT
 Build order by (if needed)
 CMN_SQL_PKG.CREATE_ORDER_BY
 Retrieve global fields into local variables
 CMN_SQL_PKG. RETR_SQL_STMT_FIELDS
 Append to query block (When finished)
 Execute query (When finished)

9. 08/31/18 For a Better Future 9
Build Where Statements
 The CMN_SQL_PKG.WHERE_STMT creates
where clause based on column name and
operator passed in.
 IF input value is passed in then continue on.
 Build the constructor operator (AND or OR)
 Build where clause based on operator passed
in. Valid operators are:
 ‘LIKE’-(varchar2 only), '=','<>','!
=','>','>=','<','<=', BETWEEN,an IN. Note : IN
clause needs data passed in following way
(value1,value2,value3…).

Additional Operators
 SUB-QUERY – supports <column>
IN (<SQL>).
 ADD_LINE – Allow you to add you
own SQL line.
 EXISTS
 NOT EXISTS
 HAVING

11. 08/31/18 For a Better Future 11
Real Life
 We used Quick Query in most form
development.
 It a basic building block for other
DMS modules like criteria,
advanced query, reporting, and
etc.
 Quick Query is a core
infrastructure piece for now and
the future.

12. 08/31/18 For a Better Future 12
What This Means
 Quick Query should be used when
your building SQL statement in the
development process.
 Quick Query to key to a modular
approach to build SQL statement
now and future rewrite.

Next Steps
 Review Tech docs for Advanced
Query, Form Query, and SQL
Build.
 Answer questions?
 Next Lecture is Batch Reporting?
