TSQL Help

  • All,

    I am trying to split a string down into 2 seperate strings using TSQL.

    i.e.

    name                                   

    Acrobat 7.0 Professional          

    DemoShield 7.5

    name                         version

    Acrobat                       7.0 Professional

    DemoShield                   7.5

    I basically want to split the first occurence of a number after a space in a string into 2 seperate strings.

    Any help would be appreciated

    Regards

  • RTRIM(LEFT([column],PATINDEX('%[0-9]%',[column])-1)) AS [name]

    SUBSTRING([column],PATINDEX('%[0-9]%',[column]),255) AS [version]

    Is it possible for the string not to have a number?

  • or use

    RTRIM(LEFT([column],PATINDEX('% [0-9]%',[column])-1)) AS [name]

    SUBSTRING([column],PATINDEX('% [0-9]%',[column]),255) AS [version]

    if you want to include a space before the number in case the name portion contains numbers

  • I'm sorry David but I just don't see any difference between the 2 statements.  Care to highlight it for me?

  • I had the same problem, but after a while I found the difference

    RTRIM(LEFT([column],PATINDEX('%[0-9]%',[column])-1)) AS [name]

    RTRIM(LEFT([column],PATINDEX('% [0-9]%',[column])-1)) AS [name]

    Do you see the difference now that both statements are immediately adjacent, Remi? There is one extra space after the % sign.

    Reminds me of "Where is Wally??" cartoons

  • Thanx Vlad.

    Now here's the interesting part.  How is david gonna highlight that space in red without using an underscore ?

  • RTRIM(LEFT([column],PATINDEX('%[0-9]%',[column])-1)) AS [name]

    RTRIM(LEFT([column],PATINDEX('% [0-9]%',[column])-1)) AS [name]

  • Ooops! Sorry about that

  • Ok that was too easy for you guys .

  • Guys,

     

    I get the following error when running the following command:

    RTRIM(LEFT([name],PATINDEX('% [0-9]%',[name])-1)) AS [name],

    SUBSTRING([name],PATINDEX('% [0-9]%',[name]),255) AS [version],

    Invalid length parameter passed to the substring function.

    Regards

  • It works for me, so it will probably be something in your data structure.

    What is the length and datatype of the column you want to parse?

    declare @name varchar (255)

    set @name = 'SM Widows 3.1'

    select RTRIM(LEFT(@name,PATINDEX('% [0-9]%',@name)-1)) AS [name]

    select SUBSTRING(@name,PATINDEX('% [0-9]%',@name),255) AS [version]

    name

    ---------------------------------------------------------------------------

    SM Widows

    (1 row(s) affected)

    version

    --------------------------------------------------------------------------- 

    3.1

    (1 row(s) affected)

    If I change @name to varchar(10), I get precisely the same error message you did - so it will probably be something along this line.

  • The name column is VARCHAR(255).

     

     

  • You will get the error if the column does not contain a number preceeded by a space

    if so try this

    LEFT([name],PATINDEX('% [0-9]%',[name]+' 1')-1) AS [name],

    SUBSTRING([name],PATINDEX('% [0-9]%',[name]+' 1')+1,255) AS [version]

    Note the spaces (I did not colour them red)

  • I don't mind for a single script.  But it was hard to figure out the difference when they were not side by side .
