CRUD Operations in Canvas App: Part I

In this part of CRUD Operations in Canvas App series , we will see in deep of Read operation.

We can perform Reading in Canvas App using Filter() , Search() and LookUp() functions.

Read Data Using Filter()

Syntax: Filter(*DataSource,Condition 1,Condition 2,…)

Toys (Table)

Filter(Toys,Color=’Red’)

This Example will give all Toys whose color is red

Filter(Toys,Color=’Red’,Age=3)

Read Data Using Search()

Syntax: Search(*DataSource,”String To Search”,Column 1,[Column 2,…])

Search() function give records from Table/Collection which contains Conditional Column contains all or part of “String to Search” .

Toys (Table)

Search(Toys,”Re”,”Color”) or Search(Toys,”Red”,”Color”)

This Example will give all Toys whose color is red

Filter(Toys,”e”,”Color”)

Read Data Using LookUp()

Syntax: LookUp(*DataSource,Condition[,Reduced Formula])

DataSource: It could be Table of Dataverse or Collection

Condition: It is check to get exact record

Reduced Formula: Using this formula, we can reduce the record to single value

LookUp() function give single record from Table/Collection that meets the condition.

Toys (Table)

LookUp(Toys,Color=’Red’)

This Example will give all Toys whose color is red

LookUp(Toys,Color=’Red’,Age)

3

The above example give only single value 3 instead of Record, because we apply Reduced formula and got only Age of Matching Record.
