MySQL select query return unrelated output -

- 

select updatedate, id,cssn,clname,cfname,cdob,cdod,ccity,cstate,chospital,ccurstatus,cmmrcashworker,ctelephone med_patient ccurstatus!='completed' , cmmrcashworker = '2' , chospital = '1234' or chospital1 = '1234' or chospital2 ='1234' , updatedate between '1/30/2010' , '1/28/2010' order id desc'

output:

updatedate   chospital   chospital1     chospital2  01/15/2010   1234  01/15/2010   1234

but acutally knowledge query must return empty row.

where mistake in query?

try adding parentheses chospital condition, otherwise or not expect:

ccurstatus!='completed' , cmmrcashworker = '2' , (chospital = '1234' or chospital1 = '1234' or chospital2 ='1234') , updatedate between '1/30/2010' , '1/28/2010' order id desc'

also:

... updatedate between '1/30/2010' , '1/28/2010' ...

^ doing string compare rather date comparison, try changing to:

... updatedate between '2010-01-30' , '2010-01-28' ...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
