[Zope] Allowed SQL statements for ZSQL

[andreas rippel]

Hi all,

I'm looking for the SQL grammar, which is allowed/supported by ZSQL.
E.g. the point is, how does ZSQL support sql-transaction expressions.
E.g. "select NOW()" is a legal expression for MySQL, but causes a parse-error in ZSQL.
There seems to be a "standard" inclusion of a limit clause within ZSQL
for security and/or overflow reasons.
Does anybody know the grammar?
Are there considerations to suit or extend the grammar?

Thanks
   Andreas
