PreparedStatement

[Geert Van Damme <ge...@vdab.be>]

Hi all,

The docs say a prepared statement is created whenever a <esql:parameter/> tag appears in the query. If I use this tag in a nested query (not a subquery in sql but a nested query in XSP), will the same prepared statement be used for every iteration or will the esql:parameter tag create a new prepared statement every time (which would kind of disable an important use of a prepared statement) ?

Thanks
Geert

It will create the statement multiple times. However, in theory the
driver should recognize the statement and reuse the previous one.
