What is the equivalent of "if exists()" in databricks sql?

What is the equivalent of the below sql server syntax in databricks sql? there are cases where i need to execute a block of sql code on certain conditions. I know this can be achieved with spark.sql, but the problem with spark.sql()  is it does not provide the number of affected columns (insert/update/delete) after the execution of dml statement.

IF EXISTS(SELECT 1 FROM table WHERE col = value)

BEGIN

     DELETE FROM table WHERE col = value

END

ELSE

BEGIN

    <code to run in else>

END

Hi @reachrishav, In Databricks SQL, you can replicate SQL Server's conditional logic using `CASE` statements and `MERGE` operations. Since Databricks SQL doesn't support `IF EXISTS` directly, you can create a temporary view to check your condition and then use `MERGE` to perform the desired operations. Afterward, you can count the affected rows with a `SELECT` statement. This approach allows for conditional execution and tracking of affected rows without relying on SQL Server-specific syntax.

Does this help with your use case? If you have any more specific requirements or questions, feel free to ask!
