SqlObject Class

prefix, postfix etc, that must be added when certain fields are requested

conection object

the result must be distinct

filter for this level

list of the properties for which the value is know e.g. Name is know if the fileter is in the form [@Name='fff'] or [@Name='fff' and ( xxxxx ) ]

name of the xpath level

used to translate an order by on post process fields to other, supporting fields

post processes for the level

links for properties

the request for this level, it is received from one level down or from user if it is the last level

Storeage for a parent select ( when we need the tsql for the parent level, usually to insert it in prefix )

abstract function that returns the assembly in which this object has the configuration file

reports the ResultTypes supported by this level

stores a query used to test a condition , for example that a table needed to resolve this level exists, if that fails then the empty set is returned rather then exception

the SqlRequest that this level must resolve

The TSQL place holder + information that will be later transformed in TSQL

this property lives only while a request is serviced

add sql wich is necessary if the property: field, is requested

add whatever is required to support it

FilterDecoder reports that a constant is used in filter gives client a chance to modify it

the xpath scanner has detected that this property is used in filter add whatever is required to support it, return value

add whatever is required to support it, return value

add the order by clause when the tsql runs across databases

add the order by clause when the tsql runs inside one database

Add the information that the TSQL is ordered by the property name if overrideFlags is tru don't check if it is legal to use this property for order by

the xpath scanner has detected that this property is used in orderby add whatever is required to support it, return value

add to the collection of properties

name property is used in filter

Allow subclasses to add anything to the statement

build statement

clear all the conditional tsql which was activated for the fields in this request

calculate the list of fixed properties ( their value can be deduced from the filter )

n queries to prepare and the last one to fill the data

Get data from Sql Server. If we fail to get into a database then ignore that database

get the property name as it will be aliased in the result set to the user

fill StatementBuilder with the information for this level

get a fixed ( with known value from filter ) property of type string

returns the object properties by usage

accessor for a property by name and usage ( internal use )

get the property field if it is legal for the usage, else throw

until we have a formal way so that each object declares which properties it uses for urn try this best guess aproach

initialize the connection info and xpath information

combine StatementBuilder from this level with what was received in the result from the parent level

load from the specfied xml doc in the assemblyObject assembly the fields specified in requestedFields; also after loading initialize static links between the properties.

load the specified file for the specified version

load the specified file for the specified version from the specified assembly

execute any PostProcess actions

a computed field has been used. return its dynamically calculated value

resolve all links which can be resolved at the local level

get the object in a clean state remove whatever was changed to resolve the current request

Retrive the request that will be sent to the parent level. we must comunicate wht info we need from the parent level here

pre initialize the object with the static info. ( resolve local links )

accessor for a property by name and usage ( internal use )
