- Create a file
jsh jbase ~/mongo -->create-file mydemo type=mongo
Notice: Assuming options 'collection=mydemo]D database=jbase write=schema'
[ 417 ] File mydemo]D created , type = OBJECT

- Populate the file with test data
jsh jbase ~/mongo -->make-demo-file 10000 mydemo (C
10,000 processed

- From a Mongo shell, we can see the data.
> db.mydemo.find()
{ "_id" : "00001", "_type" : "named", "_attr00001" : "GREG", "_attr00002" : "BAILEY", "_attr00003" : "10260 SW GREENBURG RD", "_attr00004" : "LEVEL 42", "_attr00005" : "NEW YORK", "_attr00006" : "NY", "_attr00007" : 44223, "_attr00008" : "(125) 555-1337", "_attr00009" : "(524) 555-2437", "_attr00010" : "[email protected]", "_attr00011" : [ "DIGITAL", "PSERIES", "XSERIES", "ASUS", "SPARC" ], "_attr00012" : [ "LINUX RH9", "LINUX RH9", "TRU64", "TRU64", "LINUX RH9" ], "_attr00013" : [ "jBASE", "QM", "ROS", "ROS", "D3" ], "_attr00014" : [ 416, 1470, 271, 1296, 961 ] }

- We can do anything with the data that we could for any hash file
jsh jbase ~/mongo -->COUNT mydemo
10000 Records counted
jsh jbase ~/mongo -->SELECT mydemo WITH LASTNAME EQ "MURPHY"
759 Records selected
>DELETE mydemo
759 record(s) deleted.
jsh jbase ~/mongo -->COUNT mydemo
9241 Records counted

- Run jQL against it. Note that the DICT section is also a mongo file (or collection as they call it)
jsh jbase ~/mongo -->LIST mydemo FIRSTNAME LASTNAME EMAIL OS

- As with JD files, you can create a dynamic object and write that directly to a Mongo file. When we do this, we get named fields in mongo.
$ cat test8.jabba
filename = "mydemo"
open filename to dscb else stop 201,filename
rec = new object
rec->Name = "Greg"
rec->Age = 55
write rec on dscb,"greg"

And from the Mongo shell.
> db.mydemo.find()
{ "_id" : "greg", "Name" : "Greg", "Age" : 55, "_type" : "object" }

- To emphasise this point, the (O) option to make-demo-file now creates a dynamic object and writes it to the file instead of multivalue data. Again, we can see it writes named fields to Mongo
> db.mydemo.find()
{ "_id" : "01", "firstname" : "DELLA", "lastname" : "BAILEY", "addr1" : "42 MILLI WAYS", "addr2" : "#1020", "city" : "LOS ANGLES", "state" : "MI", "zip" : "12345", "hometel" : "(666) 246-0149", "worktel" : "(666) 246-0149", "email" : "[email protected]", "hardware" : [ "XSERIES" ], "os" : [ "AIX" ], "systemtype" : [ "QM" ], "numusers" : [ 1973 ], "_type" : "object" }
{ "_id" : "02", "firstname" : "CLIVE", "lastname" : "AUBERT", "addr1" : "10260 SW GREENBURG RD", "addr2" : "LEVEL 42", "city" : "SPRINGFIELD", "state" : "CA", "zip" : "12345", "hometel" : "(524) 555-2437", "worktel" : "(124) 555-1337", "email" : "[email protected]", "hardware" : [ "ISERIES", "SOLARIS", "SPARC", "SOLARIS", "ASUS" ], "os" : [ "NT", "HPUX", "NT", "LINUX RH9", "LINUX RH8" ], "systemtype" : [ "jBASE", "ROS", "QM", "D3", "jBASE" ], "numusers" : [ 1691, 618, 1982, 845, 952 ], "_type" : "object" }
