Re: Embedded SQL: 6 views of data, 6 identical cursors, excepting the Where clause

Hi Booth,

To accomplish that, I think using SQL Descriptors is the best combination
of maintaining good performance plus code readability plus helping to
protect against SQL injection attacks.

Here is an excellent article on using them:

subject: Embedded SQL: 6 views of data, 6 identical cursors, excepting
the Where clause

A large file, with 6 views over the file. The requirement is to use SQL
to get the same data, grouped and ordered in the same way, from the file
excepting with a different Where clause. Moving the Where clause from
the Declare Cursor to the Fetch Cursor would reduce a lot of redundant
code. Is there a way to do that or similar?
