The CallText function sends a request to execute a warehouse function that returns a text value. This is often used to extract and display numbers in a more readable format or to join digits with text or symbols. 

Syntax

CallText(function_name, argument)

Function arguments:

function nameThe warehouse function to call.
argumentOne or more arguments to pass to the warehouse function.

🚧

All arguments must meet the warehouse function’s input requirements. Unsupported arguments result in an invalid formula.

Example

A table contains a Revenue column that provides restaurant revenue data as a number value. Using the CallText function, you can execute Snowflake's TO_CHAR function to extract digits and preserve the number format when combining Revenue and Currency values into a single text string. 

Concat("$", CallText("TO_CHAR", [Revenue], "999,999,999,999.00"), " ", [Currency])

Returns the Revenue value as a text string and preserves the number format (999,999.999.00) upon text conversion.
