  1. Advanced Third Party Access Rebecca Pyle October, 2007

  2. Agendum – more of the same • ISQL • Microsoft Access

  3. ISQL – basics • SELECT fields or * for all fields • FROM table • WHERE criteria SELECT * FROM dba.Invoice WHERE InvoiceDate between ′2007-06-01′ and ′2007-06-30′ • Single quotes around text. • Be careful if you copy and paste – curly quotes don’t work

  4. ISQL – statistics window • Shows what and how: table and method of search • How: Index or sequential (“seq”). Seq is table scan (entire table) • Sybase 9: • Scans table unless very limiting criteria • Caches results then subsequent queries on same criteria are fast • GW users tend to see performance suffer in some circumstances

  5. ISQL – Force use of index • You can “force” the engine to use a specific index SELECT fields FROM table FORCE INDEX (index name) WHERE criteria • Example SELECT * FROM dba.Invoice force index (invinvdate) WHERE InvoiceDate between '2007-06-01' and '2007-06-30‘ • Finding index names: select * from sys.sysindexes where tname = 'invoice'

  6. ISQL – Force use of index • Not available in Access GUI • Can put in pass-through query • Query, SQL-specific, Pass-through • Speaking of which, Access and ISQL syntax similar but not exactly the same • Dba_invoice vs. dba.invoice for table names • #...# vs. ‘…’ around date values • Double vs. single quotes around text values

  7. ISQL – query from command line • ISQL queries can be run from the command line • And consequently, in a batch file • “dbisqlc” + connection parameters + select statement (one paragraph) dbisqlc -c "uid=edit; pwd=data; dsn=gblware32" SELECT * from dba.invoice where invoicedate between ‘2007-06-01' and '2007-06-03' and FOP in ('A', 'P'); output to c:\inv.txt; • Can’t use symbols that mean something to DOS. <> (not equal) doesn’t work (because > means something in DOS), Use != e.g., where Status != ‘V’

  8. ISQL – I ♥ LIST • LIST is comma-delimited • You can get a “cross-tab” file with this: select bkagt, list(distinct provider order by provider) as Provsfrom dba.invoicewhere invoicedate = '2007-04-16' and traveltype = 'a' group by bkagt;output to c:\bkagt.txtquote '' • quote '' means no quotes

  9. Access • Invoices missing service fee • Apollo invoice numbers • Original ticket information • Thru-fare calculation • City pair “include returns” • True OD with segment information • One-way tickets • Last segment • Building import files • Add/delete comment lines – Fare savings in Invoice Query

  10. Access – Invoices missing service fee • Query what’s potentially missing (fees)

  11. Access – Invoices missing service fee • Query invoice table and the Fees query • Outer join on branch and invoice number • Criteria “is null” on a field from the Fees query • Group by

  12. Access – Missing invoice numbers • GlobalWare Missing Invoices report is not always accurate because of /QA- and MCOs • These attach to the original invoice and Apollo invoice number is in comment line 115 • Query invoice and comment line 115, and create a field that is line 115 if present, else invoice number

  13. Access – Missing invoice numbers • Query comment line 115

  14. Access – Missing invoice numbers • Query invoice and comment line 115 query, and create a field that is line 115 if present, else invoice number

  15. Access - Calculated leg fare • Like commission – sum and divide by number of legs • Add Fare and TrueODNum to Segment Count query

  16. Access - Calculated leg fare • Join to Segments table on InvPayid and TrueODNum • Divide fare total from segment count by number of segments

  17. Access - City pair “include returns” • Treat AUS-DEN and DEN-AUS as the same city pair • Create field: CityPair: Iif (DepartCity<ArrivalCity, DepartCity & '-' & ArrivalCity, ArrivalCity & '-' & DepartCity) • If logic syntax in ISQL (also concatenate and field alias): IF DepartCity<ArrivalCity THEN DepartCity || '-' || ArrivalCity ELSE ArrivalCity || '-' || DepartCity ENDIF AS CityPair

  18. Access - True OD with segment information • Information that could be different on connecting flights is not necessarily in TrueOD, e.g., fare basis • To get this information, join Segments and TrueOD tables via InvPayId and TrueODNum • To get TrueOD only segments in results, group by and pick an aggregate (min or max) for FareBasis

  19. Access - True OD with segment information

  20. Access - One-way tickets • Segments with only one true OD • Max(trueOD) = 1 • Also • Not void • Not refund • Can get info from invoice also if needed (invoice date for criteria, tkt #, etc.) • Might want to exclude Amtrak (OX not accurate)

  21. Access - One-way tickets

  22. Access – Last Segment • For Arrival manifest-type reports • Query segments for greatest segment number per Payid

  23. Access – Last Segment • Query segments and that query

  24. Access - Building import files • Export from one GW and import into another • Export from something else (e.g., website) and import into GW

  25. Access - Building import files • Account IDs, Invoices (including segments and comments), GL • All are flat files • Account IDs and Invoices files are tab-delimited • GL file is fixed-length fields • Account Id is easy; Invoices tricky particularly if you need segments or comments, GL not too bad once you figure out the number fields

  26. Access - Building import files • Basic steps • Build a table in Access that looks like the file • Query data source (e.g., AccountID table) and append to Access table • Export the Access table to text file • Import into GlobalWare • You can build a macro to automate the query and export steps

  27. Access – Add/delete comment lines • EDIT user has insert and delete rights to the Comments table • Fare savings through Invoice Query • Calculate fare savings • Store in Comment line • Define comment line in Invoice Query

  28. Access – Add/delete comment lines • Calculate fare savings • If MaxFare is zero, savings = zero • Otherwise, MaxFare minus TotalCost • If you do fare savings on exchanges the GW way, add the Exchanged amount back in • Saved: IIf([MaxFare]=0,0,[MaxFare]-[TotalCost]-[Exchange]) • Exchange is a negative value, so you subtract it

  29. Access – Add/delete comment lines • Store in comment line fields • Store PayId in InvPayid • Store a number in LineNum • Store Saved in Data • Append to Comments table

  30. Access – What else? • I know we didn’t cover all of these topics in PHX • If you have questions, please feel free to email me – my email address is in the attendee list
