I am trying to create UDF Scalar Function in Azure Synapse Analytics, but I am getting the error given below. I am trying to create table variable or temp table inside the Scalar Function but getting an error.

Msg 105041, Level 16, State 1, Line 9
The SELECT statement is not allowed in user-defined functions.

SELECT @min = MIN(id) , @Max = MAX(id) FROM #Temp

WHILE (@min IS NOT NULL AND @min <= @Max )

    Thanks for the ask and using Microsoft Q&A platform .
    As I understand the ask here is how to use a SELECT statement in a scalar function in Synapse , please do let me know if thats not the case .

    Unfortunately at this time we cannot use a SELECT statement in the body of the function . Please read about this more here

    We can use a SELECT in table valued function which is called out here . Adding a example with the snashot for clarity below .
