ADM Reference

prepareQuery

Internal function. Prepares the database query for some querying object such as a SmartDataObject.

Location: query.p

Parameters:

INPUT pcQuery AS CHARACTER

The complete query expression.

Returns: LOGICAL

Notes:

The main purpose for this is to prepare a query on an AppServer. You can do this in two different ways:

addQueryWhere, assignQueryWhere manipulates a client-side property that openQuery checks and uses as input to this method.
setQueryWhere calls this method and blank properties used by 1 in order to make openQuery NOT call this.
