SQL Format on a merge statement with multiple case statements

Looking for a way to alter the format style to correctly layout what amounts to multiple case statements in a sql merge statement,  for example:

MERGE targetTable AS t
    USING sourceTable AS s
    ON (t.keyfield = s.keyfield)
    WHEN MATCHED AND t.HashBytes <> s.Hashbytes THEN
        UPDATE Set ......   /* the update statement is formatted correctly)
    WHEN NOT MATCHED BY TARGET THEN
        INSERT
        (
            column1,
            column2,
            column3
        )
        VALUES
        (
            CASE
                 WHEN s.Column1 = '' THEN
                     NULL
                 ELSE
                     s.Column1
            END, s.Column2, s.Column3      /* why are these not on separate lines? */
        )

    Hi @dkekish

     

    Thank you for reaching out on the Redgate forums regarding your SQL Prompt layout query.

     I think it may be worth looking at the INSERT section of the Formatting styles (Formatting styles > Clauses > INSERT

    There is a setting 'Place subsequent values on new lines' 

    Setting this to 'Always' does seem to change that nested behavior in your code snippets.

    You can further modify the behavior of each case statement through Formatting styles > Expressions > CASE

    This should tackle your two examples with non-case inserts appearing on the same line


     

    and also your example with 3 case checks

     

     

    Is this the type of behavioral change you are wanting to see with your style?

    its worse if you have multiple case statements, then you end up with

    CASE
                    WHEN s.COL1= '' THEN
                        NULL
                    ELSE
                        s.Col1
                END, CASE
                         WHEN s.Col2= '' THEN
                             NULL
                         ELSE
                             s.Col2
                     END, CASE
                              WHEN s.Col3 = '' THEN
                                  NULL
                              ELSE
                                  s.Col3
                          END
