Methods

GetAliased()

public IReadOnlyCollection<IQueryElement> GetAliased()

Returns

IReadOnlyCollection<IQueryElement>

GetColumnAlias(SqlColumn)

Effective column alias: the finalized alias recorded by the aliasing pass, otherwise derived from the column's expression - resolving sub-expression aliases through this context so finalized names are honoured (mirrors SqlColumn's own derivation, but context-aware). This is the crux of non-mutating aliasing: derivation must read finalized names, not stale nodes.

public string? GetColumnAlias(SqlColumn column)

Parameters

column SqlColumn

Returns

string

GetFieldName(SqlExpressionBase)

Effective field physical name: the finalized name recorded by the aliasing pass (for derived-table / CTE source fields), otherwise the field's own physical name - PhysicalName for a table field, the finalized name of its definition field for a CTE reference field (CteField), or the delegated Name for a CTE definition field (SqlCteField).

public string GetFieldName(SqlExpressionBase field)

Parameters

field SqlExpressionBase

Returns

string

GetTableAlias(SqlTableSource)

Effective table-source alias: the finalized alias recorded by the aliasing pass, otherwise derived from the node - resolving a nested table source through this context so finalized names are honoured (mirrors SqlTableSource's own derivation, but context-aware).

public string? GetTableAlias(SqlTableSource tableSource)

Parameters

tableSource SqlTableSource

Returns

string

GetUsedTableAliases()

public HashSet<string> GetUsedTableAliases()

Returns

HashSet<string>

RegisterAliased(IQueryElement)

public void RegisterAliased(IQueryElement element)

Parameters

element IQueryElement

RegisterAliased(IReadOnlyCollection<IQueryElement>)

public void RegisterAliased(IReadOnlyCollection<IQueryElement> elements)

Parameters

elements IReadOnlyCollection<IQueryElement>

SetColumnAlias(SqlColumn, string?)

Parameters

Parameters

name string

SetTableAlias(SqlTableSource, string)

public void SetTableAlias(SqlTableSource tableSource, string alias)

Parameters
