There appears to be a difference in the results from the following SQL statement when run on an 8.1.5 version versus a 8.1.8 version:
SELECT T1.MRPtPro AS MRPtPro, T1.MRPtDOB, T1.MRPtSSN, T1.MRPtNbr, T2.MRMDNam AS MRPtProN, T1.MRPtChtCmpFlg, T1.MRPtPhA, T1.MRPtPhP, T1.MRPtPhS, T1.MRPtFNam, T1.MRPtLNam, T1.MRPtSts, T1.PrtNbr FROM (MR0011 T1 LEFT JOIN MR00051 T2 ON T2.PrtNbr = T1.PrtNbr AND T2.MRMDNbr = T1.MRPtPro) WHERE (T1.PrtNbr = 1 and T1.MRPtSts = 'A' and T1.MRPtLNam >= 'person ') AND (T1.MRPtLNam < 'persoo ') ORDER BY T1.PrtNbr, T1.MRPtSts,
T1.MRPtLNam, T1.MRPtFNam
The column MRPtLAN has both upper and lower case data.
The 8.1.5 version shows all matches both upper and lower case. While the 8.1.8 version shows only those entries that are lower case. Any ideas as to why this is?
We would like it to show all matches (case-insensitive) that are returned in 8.1.5 but would like to be on a newer version of the database 8.1.8 and eventually 8.2.X.
Both databases are UTF-8 encoding and running on REDHAT EL 4.0. Both databases were created from a pg_dump that came out of a 7.4.5 version of Postgresql with SQL_ASCII encoding. I don’t think the encoding should matter but included it for your review.
