It would also fail on Pervasive. For Pervasive to get the list of table name, you would use:
select xf$name from x$file
THen to list the columns in a table you would use:
SELECT xf$name, xe$name FROM "X$Field", x$file where xe$file = xf$id group by xf$name, xe$name
You can safely disregard any columns that start with "NN_" and have a datatype of 227.
>>select xf$name from x$file
Is xf$name a constant in above command?
Do I replace "file" with the name of a file?
Do you have any good links with more info?
I notice there's no Pervasive SQL topic area.
Does Pervasive SQL use BTrieve as part of it's DB engine?
Are they associated with each other some how?
Pervasive.SQL is the current version of Btrieve. "xf$name" is the name of the column in the system table X$FILE (you can double click it within the PCC and see what's all's there).
To get a list of columns for a specific table, you'd need to look up the table name in the X$FILE to get the XF$ID which is in the X$FIELD table as XE$FILE column. So for example:
select XE$NAME from X$FIELD where XE$FILE = (select XF$ID from X$FILE where XF$NAME = 'myTableName')
