HTML mail from SybaseIQ- Sendmail linelength problem (weird ! character)
One of the best ways to send HTML mail from SybaseIQ on IBM AIX is to use sendmail.
Unfortunately sendmail has linelength limit (2040 characters default). After 2040th character sendmail is adding ! and new line characters to text which is ruining HTML.
To fix this problem:
Unfortunately sendmail has linelength limit (2040 characters default). After 2040th character sendmail is adding ! and new line characters to text which is ruining HTML.
To fix this problem:
- Change Linelimit info in Sendmail.cf file. Add L=4096 (or any other suitable value) to corresponding mailer.
- To identify correct mailer check mail log at /var/log/maillog file. Mailer name is mostly Mrelay
- After these steps ! character shall be removed from your mail.
- You may add || CHAR(13) || CHAR(10) after each </tr> statement to add new line in SQL as well.
execute immediate 'exec xp_cmdshell ''(echo "From: myadreess@mail.com."; echo "To: dest1@mail.com,dest2@mail.com"; echo "MIME-Version: 1.0";echo "Content-Type: text/html"; echo "<html><body bgcolor=black><blockquote><font color=green>GREEN</font> <font color=white>WHITE</font> <font color=red>RED</font><font color=blue>Powered by Sybase IQ</font></blockquote></body></html>") | sendmail -t''';

Sybase IQ - Word Index limitations
"words exceeding the maximum permitted word length not supported" error means you did not defined enough/correct delimiters for WD index.
Maximum word length for WD index is 255 characters. You need to delimit your text with correct delimiters to reduce maximum word length under 255.
For columns, which holds SQL statements, delimited by ' ,;=' clause seems valid.This statement means string will be delimited by any of those characters. '.' character is willingly ommited to be able to find 'owner.tablename' format faster.
You may check Sybase Infocenter for detailed information.

Sybase IQ equavelent for while break structure
Sybase IQ uses labes to exit loops. Instead
of break you have to use exit label structure.
Sample "while break" code:
.
.
lbl:
WHILE 10 <15 LOOP
SET i = 1;
IF i = 1 THEN
LEAVE lbl;
END IF;
END LOOP lbl
.
