示例1: FindExpressionsByName
/// <summary>
/// Finds all registered tables or columns with the given name.
/// We exclude parameter because they won't be prefixed/suffixed the same way (well, that's a guess, I hope it's a good one)
/// </summary>
/// <param name="name"></param>
/// <param name="builderContext"></param>
/// <returns></returns>
protected virtual IList<Expression> FindExpressionsByName(string name, BuilderContext builderContext)
{
var expressions = new List<Expression>();
expressions.AddRange(from t in builderContext.EnumerateAllTables() where t.Alias == name select (Expression)t);
expressions.AddRange(from c in builderContext.EnumerateScopeColumns() where c.Alias == name select (Expression)c);
return expressions;
}示例2: CheckTablesAlias
/// <summary>
/// Give all non-aliased tables a name
/// </summary>
/// <param name="builderContext"></param>
protected virtual void CheckTablesAlias(BuilderContext builderContext)
{
var tables = builderContext.EnumerateAllTables().ToList();
