subject: SQL problem with Java -- JDBC driver seems to be turning
mixed case names into UPPERCASE

I was trying to use more descriptive names in a data base created with
SQL. I admit this is a little overboard, but here is an example:

Data Field Buffer Buffer Field Column
Field Type Length Length Position Usage Heading
DUEDAY4 BINARY 4 0 2 414 Both
"dueDayOfMonth4"
Alternative name . . . . . . . . . . . . :
"dueDayOfMonth4"
Default value . . . . . . . . . . . . . . : None
DUEDAY4A CHAR 1 1 416 Both
"dueDay4WeekendActio
n"
Alternative name . . . . . . . . . . . . :
"dueDay4WeekendAction"
Allows the null value
Default value . . . . . . . . . . . . . . :
'0'
Coded Character Set Identifier . . . . . : 37


When I execute a SELECT statement I get a -206 error, here is the message:

[SQL0206] Column DUEDAY4WEEKENDACTION not in specified tables.

Notice that the variable name has been upper cased.

I am guessing that the field - DUEDAY4 is being used, not the alternative
name dueDay4WeekendAction. Does it have to be enclosed in double quotes
in the SQL?

Does that make sense?

If so, how do you tell the SQL engine to use the alternative name when
creating the connection. I looked at the properties to include in the
JDBC URL and didn't see anything.

Thanks

Because the column name is actually "dueDay4WeekendAction"

Because it wasn't enclosed in quotes when you specified it in the
SELECT statement.

alternative
name dueDay4WeekendAction.

Why do you think that? If you'd specified the short name it would
have been used.


Does it have to be enclosed in double quotes in the SQL?

Yes (if by "it" you mean the alternative name).


Does that make sense?

Yes.

I don't think you can set a property for this. If you want to use the
short names then just specify them on the SQL statement.

Simon Coulter.

Are you saying column names on the 400 are case sensitive?
