Filter Search Lookup in PowerApps

 

In PowerApps, we can use the Filter, Search, and LookUp function.

 

Filter Function

 

The Filter function finds the records in a table. It must satisfy a formula. We can use Filter to find a set of records with the conditions. If the condition becomes true, it displays the records; else, it discards.

 

Syntax

 

Filter (Table, Formula1 [, Formula2, ... ] )

 

Explanation

• Filter-Keyword
• Table-Table Name
• Formula- We apply the formula (If you search more than one column)

Follow the below steps to work with Sort in PowerApps.

 

Step 1 - Log in to the PowerApps

 

After downloading the PowerApps from the Windows Store, we need Microsoft related organization’s Office 365 ID or (MSDN, Microsoft, Skype, Office 365, etc.) to login with it.

Step 4 - Designing the App

 

Now, let's start designing the app. On the left side, we can see the individual screens for adding our data. On the right side, we see the list of Layouts. On the top, there is a formula bar. There, we have the Properties of the screen that we select. 

 

 

Step 5 - Choose the Blank Layout.

 

 

Step 6 - Insert a Button from the Insert menu.

    ProductNo: 112,
    ProductName: "DVD",
    Rate: 1500
}, {
    ProductNo: 856,
    ProductName: "Modem",
    Rate: 500
}, {
    ProductNo: 469,
    ProductName: "Processor",
    Rate: 5000
})

Step 8 - Run the app.

Search Function

 

The Search function finds records in a table. The string may occur anywhere within the column. Searching is case-insensitive and unlike Filter and LookUp, the Search function uses a single string to match instead of using a formula.

 

Syntax

 

Search( Table, SearchString, Column1 [, Column2, ... ] )

 

Explanation

• Search - Keyword
• Table - Table Name
• SearchString - The string to search for.
• Column(s) - The names of columns within Table to search

ClearCollect(SivaEnterprise,Search (SivaEnterprise, "DVD", "ProductName"))

• SivaEnterprise-It’s the table name
• Search-Keyword
• SivaEnterprise- Collection name
• DVD, ProductName-Field name and Column name to Search

Output

 

 

LookUp Function

 

The LookUp function finds the first record in a table that satisfies a formula. Use LookUp to find a single record that matches one or more criteria.

 

Syntax

 

LookUp( Table, Formula [, ReductionFormula ] )

 

Explanation

• LookUp - Keyword
• Table - Table Name
• Formula- We apply the formula (If you search more than one column)
• ReductionFormula - Optional. This formula is evaluated over the record that was found, reducing the record to a single value.
