6 Functions 🧮

SQL expressions can utilize a myriad of functions alongside field values and constants. Each function needs a set number of 'arguments' and yields one value.

6.1 Aggregate functions 📊

Refer to Section 10.3 for details.

• YEARPART 📅
  YEARPART(date) - Retrieves the year of the date.

• MONTHPART 📆
  MONTHPART(date) - Determines the month of the date.

• DAYPART 🌞
  DAYPART(date) - Extracts the day from the date.

• DATEPART 🗓
  DATEPART(date) - Provides the date while removing minutes.

• TIMEPART ⌚
  TIMEPART(date) - Gives the time in minutes from the date.

• YEARMONTHPART 📅📆
  YEARMONTHPART(date) - Shows year and month as a string.

• MONTHYEARPART 📆📅

Emojis SQL in ICM InfoWorks - 11 One-To-Many Links 🌐

 11 One-To-Many Links 🌐

One-to-many links enable queries to consider linked objects, even when there's a possibility of having none, one, or multiple linked objects.

The keywords all_us_links and all_ds_links help in joining ALL upstream or downstream links to any node or link type.

Available One-To-Many Links:

From	To	Name
Node	Link	us_links
Node	Link	ds_links
Node	Subcatchment	subcatchments
Link	Link	us_links
Link	Link	ds_links
Subcatchment	Lateral link	drains_from
Subcatchment	Lateral link	lateral_connected_links

🔍 How to Use them in Queries:

11.1 Determining Linked Objects 🔗

Utilize ANY(linkname.*) to check if linked objects exist. Example: ANY(us_links.*)

11.2 Counting Linked Objects 🧮

Employ COUNT(linkname.*) to tally the linked objects. For instance: COUNT(manhole_surveys.*)=0

11.3 Aggregate Functions 📊

Almost all aggregate functions from the array fields section, except FIRST and LAST, apply for one-to-many links.

11.4 'Bare' One-To-Many Fields Usage 📋

You can assign values to one-to-many fields through an assignment clause outside an aggregate function. For example:

• With only a SET sub-clause: SET us_pipes.width = 123 sets the width for every upstream pipe.
• With a WHERE sub-clause: SET us_links.width = 234 WHERE shaft_depth = 1650 will adjust the width for every upstream link where the shaft depth equals 1650.

11.5 Interplay Between 'Bare' Fields & Aggregate Functions ⚙️

If one-to-many field values are used outside aggregate functions in a WHERE sub-clause and inside aggregate functions in the SET sub-clause, the aggregate functions in the SET sub-clause will only be evaluated for objects linked to the current object where the WHERE sub-clause holds true.

However, if you incorporate an aggregate function IN the WHERE sub-clause, it will run for all objects linked via the one-to-many link to the current object.
