1 Advanced Third Party Access Rebecca Pyle October, 2007

2 2 Agendum – more of the same >ISQL >Microsoft Access

3 3 ISQL – basics >SELECT fields or * for all fields >FROM table >WHERE criteria SELECT * FROM dba.Invoice WHERE InvoiceDate between and >Single quotes around text. >Be careful if you copy and paste – curly quotes dont work

4 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 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 ' ' and ' >Finding index names: select * from sys.sysindexes where tname = 'invoice'

6 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 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 ' and ' ' and FOP in ('A', 'P'); output to c:\inv.txt; >Cant use symbols that mean something to DOS. <> (not equal) doesnt work (because > means something in DOS), Use != e.g., where Status != V

8 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 Provs from dba.invoice where invoicedate = ' ' and traveltype = 'a' group by bkagt; output to c:\bkagt.txt quote '' >quote '' means no quotes

9 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 10 Access – Invoices missing service fee >Query whats potentially missing (fees)

11 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 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 13 Access – Missing invoice numbers >Query comment line 115

14 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 15 Access - Calculated leg fare >Like commission – sum and divide by number of legs >Add Fare and TrueODNum to Segment Count query

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

17 17 Access - City pair include returns >Treat AUS-DEN and DEN-AUS as the same city pair >Create field: CityPair: Iif (DepartCityIf logic syntax in ISQL (also concatenate and field alias): IF DepartCity

18 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 19 Access - True OD with segment information

20 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 21 Access - One-way tickets

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

23 23 Access – Last Segment >Query segments and that query

24 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 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 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 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 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 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 30 Access – What else? >I know we didnt cover all of these topics in PHX >If you have questions, please feel free to me – my address is in the attendee list
