hi...

using python v2.6, using the mysqldb lib

the test tbl looks like:
DROP TABLE IF EXISTS `functionError_TBL`;
CREATE TABLE `functionError_TBL` (
`parentFunction` varchar(100) NOT NULL default '',
`currentFunction` varchar(100) NOT NULL default '',
`parentFunctionID` int(10) NOT NULL default 0,
`errorStatus` int(1) NOT NULL default 0,
`clientServerUUID` varchar(100) NOT NULL default '',
`processTime` timestamp NOT NULL default 0,
`CollegeID` int(10) NOT NULL default 0,
`CrawlID` varchar(200) NOT NULL default '',
`CollegeName` varchar(200) NOT NULL default '',
`CollegeAbbrv` varchar(200) NOT NULL default '',
.
.

the test script looks like
.
.
tlist= [(1, 1, 1281502771)]

ins="insert into functionError_TBL "
ins=ins+"(errorStatus, CollegeID, processTime)"
ins=ins+" values "
ins=ins+" (%s,%s, from_unixtime(%s))"
db.executemany (ins, tlist)


if the parameter is :
(%s,%s, from_unixtime(%s))"

it appears to work, data is inserted correctly...

if the parameters are changed to
(%s,from_unixtime(%s), %s)"

along with the corresponding insert portion, and the test list, an
error is generated..

this implies that something is going on with the use of the
"from_unixtime" that i don't fully understand..

thoughts/pointers/comments...

thanks


thoughts on how to resolve this would be greatly appreciated.

thanks

hey dennis...

umm.. given that i'm building the ins var/string to insert into the
execute... i can't just place the triple quotes around it..

are you saying that the execute should have quotes placed around it
within the execute
so it would be something like
execute("\""+sel""\""...

or are you saying that within python i can just extend the line for
the "sel" on multiple lines..

as to the err.
i'm getting a " >>> Warning: Data truncated for column

it appears that if i place the >>from_unixtime(%s) << at the end of
the paramaters, then everything works.. but if i place it within the
"%s" block.. the error is generated.

I'm assuming there's some way to wrap the from_unixtime(%s) so it
could be used as

%s,%s,%s, from_unixtime(%s), %s, %s,...

in checking the docs/spec.. i didn't see anything that discussed this...

thanks
