I inserted the string 'ñ' into an ISO88591 column, then selected ascii(x) from that column. (The 'ñ' character is the n-with-tilde, which is used in the Spanish language.) The value I got back was 241 (which seems right; the 'ñ' character has an encoding of hex 'f1' = 241 decimal in the ISO88591 code page). So, I think the behavior in Trafodion has changed. I also tried this on a UTF8 column. There, the ASCII function seems to work fine so long as the encoding is less than or equal to 127. Again, I inserted 'ñ', and then selected ascii(x) from that column. This time I did get an error, but a different error: *** ERROR[8428] The argument to function ASCII is not valid. I suspect what is going on there is the SQL run-time is allowing the ASCII function on UTF8 characters only if the UTF8 character is single-byte. > Correct the Syntax Descriptions for *ASCII Fucntion* in Trafodion SQL > Reference Manual > -------------------------------------------------------------------------------------- > > Key: TRAFODION-3048 > URL: https://issues.apache.org/jira/browse/TRAFODION-3048 > Project: Apache Trafodion > Issue Type: Documentation > Reporter: Liu Yu > Assignee: Liu Yu > Priority: Major > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
