How to find what the sql excepion was with mysql

Ruby
#1

I got an exception
E:/TradingTools/CODE/ImportTrade.rb:20:in `execute’

The associated piece of code is
st= dbConn.prepare("insert into raw_data

(SYMBOL,ACTION,SIZE,PRICE,DATE_TIME_OF_TRADE ,EXECUTION,ACCOUNT_ID)
VALUES(?,?,?,?,?,?,?)")
st.execute(dataArray[0],dataArray[1],dataArray[2],dataArray[3],tradeDate,dataArray[5],dataArray[6])
st.close

How do i find out what the exception details were that was triggered
at st.execute in this case.
any assistance will be appreciated

Assuming the exception object is e, you can check out e.

Exceptions and rescuing them works like this (assuming you want to
st.execute throws a MysqlException):

begin
st.execute(dataArray[0],dataArray[1],dataArray[2],dataArray[3],tradeDate,dataArray[5],dataArray[6])
rescue MysqlException => e
puts e.message
end
