RAISERROR N'<\<%7.3s>> syntax, is there documentation that explains this syntax? RRS feed

  • Question

  • Dear Microsoft Forum Member,

    I am reviewing the RAISERROR Microsoft documentation and reference is made to the error message with the syntax N'<\<%7.3s>>'. I do not understand what this syntax is saying. Is there any

    documentation that explains the meaning behind each of these characters? Please let me know.

    Thank you.

  • It is explained at RAISERROR (Transact-SQL) => % [[flag] [width] [. precision] [{h | l}]] type

    %7.3s stands Parameter numeric with precise 7 and scale 3, followed by a string.

  • To clarify, here is an example:

    RAISERROR('This is a test: <%7.3s>', 1, 1, 'Nattmössa')

    This results in:

    This is a test: <    Nat>
    Msg 50000, Level 1, State 1

    Since this is matter of a string, "scale" is misleading terminology. What it actually means that the width of the value is 7 ot which only three are printed, the rest is blank space.

    This is also explained in the topic for RAISERROR, but it is not particularly intuitive. Nor is it particularly useful.
