just learned some painful lessons while using instantdb+dods that i thought
i'd share:

	1.  don't specify "User" as a table name nor "user" as an
attribute/fieldname in DODS
		-these are reserved words in instantdb

	2.  don't use "." in your table name (e.g. myProject.myTable) in
DODS (see the table tab of your data object)
		-when i did this, i got the following error when i tried
executing the create_table.sql file using ScriptTool

		Don't understand SQL after: "create"
		Expected: "ON" found: "."
		       at
org.enhydra.instantdb.db.SQLProg.execute(SQLProg.java:219)
		       at
org.enhydra.instantdb.jdbc.idbStatement.execute(idbStatement.java:235)
		       at
org.enhydra.instantdb.jdbc.idbStatement.executeUpdate(idbStatement.java:103)
		       at org.enhydra.instantdb.SampleThread.run(ScriptTool.
java:474)
		       at java.lang.Thread.run(Thread.java:484)

	3.  don't specify extra carriage returns in between the beginning
and end of a create table sql statement
	     in your .sql files.  for example:

1		e create table Store
2		(
3		    storeName VARCHAR(32) DEFAULT "" NOT NULL   ,
4		    distributor DECIMAL(19,0)  NOT NULL  REFERENCES
Distributor ( oid ) ,
5
6
7		    dateCreated DATE  NOT NULL   ,
8		    dateModified DATE  NOT NULL   ,
9
10
11		    oid DECIMAL(19,0) NOT NULL PRIMARY KEY,
12		    version INTEGER NOT NULL
13		);

	make sure to remove the carriage returns on lines 5,6,9,10.

	for some reason, when i had blank lines in between (which we
auto-generated by DODS), instantdb gave me
	the following error:


	java.lang.StringIndexOutOfBoundsException: String index out of
range: 0
	        at java.lang.String.charAt(String.java:507)
	        at
org.enhydra.instantdb.SampleThread.getSQL(ScriptTool.java:189)
	        at
org.enhydra.instantdb.SampleThread.run(ScriptTool.java:265)
	        at java.lang.Thread.run(Thread.java:484)

 

it would be great if this could be added to the "getting started w/ enhydra"
guide, dods documentation, and/or the instantdb documentation in a section
called "before you start" or "things to be careful" of.  atleast until the
code is corrected.

thanks.
