// This is a generic lookup constructor that will work with any table and any column.
|
|
// It extends the capabilites of the lookup dialog in the following ways:
|
|
//
|
|
// 1) 2 columns rather than one
|
|
// 2) The ability to select DISTINCT column values
|
|
//
|
|
// Only set distinctValues equal to true if necessary. In many cases, the constraints
|
|
// of the index(es) will enforce this uniqueness. Selecting DISTINCT does require
|
|
// overhead by the database to ensure that all values returned are distinct. Therefore,
|
|
// use this ONLY when you need it.
|
|
//
|
|
// For complicated queries, you can pass in the sql select statement. This would be
|
|
// necessary if joins are involved since by default both columns must come from the
|
|
// same table.
|
|
//
|
|
// If you do query by sql statement, you must pass in the maximum length of column1,
|
|
// since it cannot be derived when you query using your own sql statement.
|
|
//
|
|
// The optional database connection can be used if you'd like the lookup class
|
|
// to use a database pointer other than the READONLY_DB of the app. This is necessary
|
|
// if records are being saved, but not committed to the db, yet should be included
|
|
// in the lookup window.
