I am iteratively building a complex query. For one step, I have
a[i] = a[i].filter(Clinical.string_value.op('=')([value[i]])).subquery()
I would like to simply just replace the value in Clinical.string value such
that all spaces are turned into underscores. My naive approach is to do
this as
replace(Clinical.string_value, ' ', '_'), but I know the syntax is invalid
in this context. How do I plug this into my SQLAlch statement? I found the
replace method
here:
http://docs.sqlalchemy.org/en/latest/core/sqlelement.html#sqlalchemy.sql.expression.func,
but it does not seem to fit my use case.
Thanks in advance!
