Team,
I have commited to CVS what I have announced a couple of days
back. Although no one objected then, this might be controversial so I
checked in only to C2.1.
Changed API
* <esql:column> replaced by generic <esql:param name="column"> like
all other taglibs do.
New tags: (name says it all)
* get-object
* get-metadata
* get-resultset
* get-column-type (as int)
Changed Behaviour
* get-columns now tries to print out complex types as well by
looking at jdbc type & if object is instance of List or Set.
Since it is non trivial to retrieve sensible names for parts of
complex types, this introduces <sql-row>, <sql-row-item>,
<sql-list>, <sql-list-item>, <sql-set>, <sql-set-item>.
* <esql:column> accepted only numbers and strings
now <esql:param name="column"> accepts expressions as well.
Example:
<esql:get-object>
<esql:param name="column"><xsp:expr>i+1</xsp:expr></esql:param>
<esql:get-object>
* <esql:row-results> & friends now enclose everything in
<xsp:content>. If superfluous, these tags just disapear when the
xsp taglib is applied. OTOH they make behaviour for those new to
esql a bit friendlier.
Example:
<esql:results>
<esql:row-results>
count=<esql:get-int column="1"/>
</esql:row-results>
</esql:results>
This would have resulted in an compile error. Now this compiles
and outputs "j=42".
For more details see my previous mails on this.
If this survives for the next week without getting me killed by angry
user / developers I'll put it into C2 and C1 as well ;-)
Chris.
