C# Class Remotion.Linq.SqlBackend.SqlGeneration.SqlGeneratingSelectExpressionVisitor

Extends SqlGeneratingExpressionVisitor by emitting "AS" aliases for NamedExpression and SqlEntityExpression instances. This should be used for the SqlStatement.SelectProjection of substatements. For the outermost statement, SqlGeneratingOuterSelectExpressionVisitor should be used.

Inheritance: SqlGeneratingExpressionVisitor, ISqlGroupingSelectExpressionVisitor
