Methods

Clone()

Creates a copy of the query elements, but shares parameter values with the original, so it is not a complete copy.

Declaration
public override object Clone()
Returns
Type Description
object

Copy of all the restrictions/joins
Overrides
Remarks

This method is used by the SentryQueryUpdater to modify a query with sentry extensions without affecting the original query.

GetMainField()

Returns information about a database field.

Declaration
public override FieldInfo GetMainField()
Returns
Type Description
FieldInfo
Overrides

GetReferencedFields()

Enumerate every FieldInfo referenced inside this argument, recursively.

Declaration
public override IEnumerable<FieldInfo> GetReferencedFields()
Returns
Type Description
IEnumerable<FieldInfo>
Overrides
Remarks

Used by Select.GetTableInfos to anchor joins for compound arguments (CASE, CONCAT, math, aggregations, function calls) that wrap fields from multiple tables. Unlike GetMainField(), which returns at most one representative field, this enumerates them all so every referenced table is discovered.
