Hi Bryan,
I tried to work with new repo and get the following error
ij> describe run;
JAVA ERROR: java.lang.Error: Missing return statement in function
java.lang.Error: Missing return statement in function

I check ij.java and see as follows
Token t=null;
String i=null;
if (jj_2_122(2)) {
i = keyword();
} else if (jj_2_123(2)) {
t = jj_consume_token(IDENTIFIER);
haveConnection();
DatabaseMetaData dbmd = theConnection.getMetaData();
String identifier = i;
if(i==null)
identifier = t.image;
if (dbmd.storesLowerCaseIdentifiers())
identifier = identifier.toLowerCase(Locale.ENGLISH);
else if (dbmd.storesUpperCaseIdentifiers())
identifier = identifier.toUpperCase(Locale.ENGLISH);
{if (true) return identifier;}
} else {
jj_consume_token(-1);
throw new ParseException();
}
throw new Error("Missing return statement in function");
According to the code when we give a key word as table the error should appear.
Why this occurs suddenly? Here I am attaching the patch.
thanks

> (attach ij to any database)
> ij> create table run (i int);
> 0 rows inserted/updated/deleted
> ij> desc run;
> ERROR 42X01: Syntax error: Encountered "desc" at line 1, column 1.

> I think this is a parser problem within ij where the "run" is taken as a
> token and that token is not included in the definition of a tablename
> expression in the grammer (should be an easy fix).
