SQL Declare Variables For SAP Business One

Using variables in SQL queries for SAP Business One is straight forward for simple select statements but what about the more complex variables or if you want to declare a variable for your SQL?

Answer: You have to get a bit more creative! See the example below.

To select a from and to date as a variable in a declare statement you have to add a nifty bit of extra code.

/*

/SELECT FROM [dbo].[VPM1] T0/

declare  @fromdate as datetime

/* WHERE */

set @fromdate = /* T0.DueDate */ ‘[%0]’

 

/SELECT FROM [dbo].[VPM1] T1/

declare  @tilldate as datetime

/* WHERE */

set @tilldate = /* T0.DueDate */ ‘[%1]’

 

 

select  OVPM.docnum, VPM1.dueDate,VPM1.CheckNum, VPM1.Branch,

VPM1.BankCode, VPM1.CheckSum, OVPM.CardName,

case

when OPCH.docnum is null then VPM2.docEntry

else OPCH.docnum

end as ‘docnum’

from OVPM INNER join VPM1 on OVPM.docnum = VPM1.docnum

left join  VPM2 LEFT JOIN OPCH ON VPM2.DocEntry = OPCH.DocEntry

on OVPM.docnum = VPM2.docnum

where OVPM.Canceled = ‘N’ AND VPM1.DueDate >=@fromdate AND

VPM1.DueDate <=@tilldate
