begin
declare @SQLQuery AS VARCHAR(2000)

SSIS package info:
SSIS package has a script task which contains the code for sending messages to MSMQ

Problem:
On exec [test_proc] ‘<xml></xml>’
Works fine

But On exec [test_proc] ‘
Error:
Message Text:<xml version=1.0>

The problem seem to be passing special characters to the script task variable
