Help Needed with Max syntax

  • Hello we have a detail table in our erp systm that generates timestamp and message info per order. We are trying to create syntax so we can show the end user summarized data. For example this below should be the output we generate through the syntax based on the picture of the detail table included.

    Order_No TimeStamp Message

    67009 2013-10-02 08.43 Order not set for auto-invoice in SVKECH

    67023 2013-10-02 08.43 Order in-use

    67023 2013-10-02 08.43 Order not set for auto-invoice in SVKECH

    109592 2013-09-06  10.27 Order in-use

    117578 2013-09-06  10.27 Failed Logistics Check

    117578 2013-12-12 13.18 Called SNM505C.PC00117578

    119171 2013-07-05 12.59 Order not set for auto-invoice in SVKECH

    This is the syntax we have so far,

    SELECT order_number, MAX(TIMESTAMP) AS Recent, Message FROM LOG Table

    group by order_number

    Any suggestions would be greatly appreciated! Thank you for your time!

  • It seems that you just need to add the column Message to your group GROUP BY statement.;-)

    Hi and welcome to the forums. It would greatly help your posts if you provide readily consumable ddl and sample data.

    Something like this:

    create table #Log

    (

    Order_Number int,

    LogDate datetime,

    LogMessage varchar(200)

    )

    insert #Log

    select 67009, '2013-10-02 08:43', 'Order not set for auto-invoice in SVKECH' union all

    select 67023, '2013-10-02 08:43', 'Order in-use' union all

    select 67023, '2013-10-02 08:43', 'Order not set for auto-invoice in SVKECH' union all

    select 109592, '2013-09-06 10:27', 'Order in-use' union all

    select 117578, '2013-09-06 10:27', 'Failed Logistics Check' union all

    select 117578, '2013-12-12 13:18', 'Called SNM505C.PC00117578' union all

    select 119171, '2013-07-05 12:59', 'Order not set for auto-invoice in SVKECH'

    I changed a couple of your column names because using reserved words as column names is painful to work with.

    The issue you are facing is you want to have a single row for each order but you also have LogMessage in the output. Which message do you want?

    This is the proper syntax but it will not return what you are looking for.

    SELECT order_number, MAX(LogDate) AS Recent, LogMessage

    FROM #Log

    group by order_number, LogMessage

    What is the expected output based on the sample data?

    Hey Sean,

    It seems that the OP wrote the expected results and attached the sample data. So adding message column to the group by seems to work fine.

    Ahh yes. I didn't look at the picture because...well...because so often the attached pictures provide little to the discussion. In this case apparently it did. 😀
