1. Your upper/lower case is screwed up between CollectionTab and
InvoiceTab; that is, CollectionTab has upper case InvCodes and
InvoiceTab has lower case, or vice-versa.
2. You have accidentally defined InvCode as VARCHAR in one table and
CHAR in another. If the InvCodes are of variable length, this would
cause failure to match because of the space-filling inherent in CHAR.
Similarly, defining the fields as different-length CHAR fields would
cause this problem.
3. Some error you or your scripts made in converting the data caused
trailing spaces to be appended to the InvCode field in one table but not
To really determine the problem, I would need to see:
1. The actual PostgreSQL tabledefs (pg_dump -s -t "InvoiceTab" database)
2. The first 10 rows of data for each table. Please cut-and-past and do
not transcribe the data, because you almost certainly have a trailing
space, case, or punctuation problem here and only an exact dump will
show the problem.
