+ * `id` is projection name of column node + * + * Example: SELECT id AS id_alias FROM test_table; + * `id_alias` is projection name of column node + * + * Calculation of projection names is done during expression nodes resolution. This is done this way + * because after identifier node is resolved we lose information about identifier name. We could + * potentially save this information in query tree node itself, but that would require to clone it in some cases. + * Example: SELECT big_scalar_subquery AS a, a AS b, b AS c; + * All 3 nodes in projection are the same big_scalar_subquery, but they have different projection names. + * If we want to save it in query tree node, we have to clone subquery node that could lead to performance degradation. + * + * Possible solution is to separate query node metadata and query node content. So only node metadata could be cloned + * if we want to change projection name. This solution does not seem to be easy for client of query tree because projection + * name will be part of interface. If we potentially could hide projection names calculation in analyzer without introducing additional + * changes in query tree structure that would be preferable. + * + * Currently each resolve method returns projection names array. Resolve method must compute projection names of node. + * If node is resolved as list node this is case for `untuple` function or `matcher` result projection names array must contain projection names + * for result nodes. + * If node is not resolved as list node, projection names array contain single projection name for node. + * + * Rules for projection names: + * 1. If node has alias. It is node projection name. + * Except scenario where `untuple` function has alias. Example: SELECT untuple(expr) AS alias, alias. + * + * 2. For constant it is constant value string representation. + * + * 3. For identifier: + * If identifier is resolved from JOIN TREE, we want to remove additional identifier qualifications. + * Example: SELECT default.test_table.id FROM test_table. + * Result projection name is `id`. + * + * Example: SELECT t1.id FROM test_table_1 AS t1, test_table_2 AS t2 + * In example both test_table_1, test_table_2 have `id` column. + * In such case projection name is `t1.id` because if additional qualification is removed then column projection name `id` will be ambiguous. + * + * Example: SELECT default.test_table_1.id FROM test_table_1 AS t1, test_table_2 AS t2 + * In such case projection name is `test_table_1.id` because we remove unnecessary database qualification, but table name qualification cannot be removed + * because otherwise column projection name `id` will be ambiguous. + * + * If identifier is not resolved from JOIN TREE. Identifier name is projection name. + * Except scenario where `untuple` function resolved using identifier. Example: SELECT untuple(expr) AS alias, alias. + * Example: SELECT sum(1, 1) AS value, value. + * In such case both nodes have `value` projection names. + * + * Example: SELECT id AS value, value FROM test_table. + * In such case both nodes have have `value` projection names. + * + * Special case is `untuple` function. If `untuple` function specified with alias, then result nodes will have alias.tuple_column_name projection names. + * Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value) AS a; + * Result projection names are `value`, `a.id`. + * + * If `untuple` function does not have alias then result nodes will have `tupleElement(untuple_expression_projection_name, 'tuple_column_name') projection names. + * + * Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value); + * Result projection names are `value`, `tupleElement(value, 'id')`; + * + * 4. For function: + * Projection name consists from function_name(parameters_projection_names)(arguments_projection_names). + * Additionally if function is window function. Window node projection name is used with OVER clause. + * Example: function_name (parameters_names)(argument_projection_names) OVER window_name; + * Example: function_name (parameters_names)(argument_projection_names) OVER (PARTITION BY id ORDER BY id). + * Example: function_name (parameters_names)(argument_projection_names) OVER (window_name ORDER BY id). + * + * 5. For lambda: + * If it is standalone lambda that returns single expression, function projection name is used. + * Example: WITH (x -> x + 1) AS lambda SELECT lambda(1). + * Projection name is `lambda(1)`. + * + * If is it standalone lambda that returns list, projection names of list nodes are used. + * Example: WITH (x -> *) AS lambda SELECT lambda(1) FROM test_table; + * If test_table has two columns `id`, `value`. Then result projection names are `id`, `value`. + * + * If lambda is argument of function. + * Then projection name consists from lambda(tuple(lambda_arguments)(lambda_body_projection_name)); + * + * 6. For matcher: + * Matched nodes projection names are used as matcher projection names. + * + * Matched nodes must be qualified if needed. + * Example: SELECT * FROM test_table_1 AS t1, test_table_2 AS t2. + * In example table test_table_1 and test_table_2 both have `id`, `value` columns. + * Matched nodes after unqualified matcher resolve must be qualified to avoid ambiguous projection names. + * Result projection names must be `t1.id`, `t1.value`, `t2.id`, `t2.value`. + * + * There are special cases + * 1. For lambda inside APPLY matcher transformer: + * Example: SELECT * APPLY x -> toString(x) FROM test_table. + * In such case lambda argument projection name `x` will be replaced by matched node projection name. + * If table has two columns `id` and `value`. Then result projection names are `toString(id)`, `toString(value)`; + * + * 2. For unqualified matcher when JOIN tree contains JOIN with USING. + * Example: SELECT * FROM test_table_1 AS t1 INNER JOIN test_table_2 AS t2 USING(id); + * Result projection names must be `id`, `t1.value`, `t2.value`. + * + * 7. For subquery: + * For subquery projection name consists of `_subquery_` prefix and implementation specific unique number suffix. + * Example: SELECT (SELECT 1), (SELECT 1 UNION DISTINCT SELECT 1); + * Result projection name can be `_subquery_1`, `subquery_2`; + * + * 8. For table: + * Table node can be used in expression context only as right argument of IN function. In that case identifier is used + * as table node projection name. + * Example: SELECT id IN test_table FROM test_table; + * Result projection name is `in(id, test_table)`. + */ +using ProjectionName = String; +using ProjectionNames = std::vector; +constexpr auto PROJECTION_NAME_PLACEHOLDER = "__projection_name_placeholder"; + +struct IdentifierResolveScope +{ + /// Construct identifier resolve scope using scope node, and parent scope + IdentifierResolveScope(QueryTreeNodePtr scope_node_, IdentifierResolveScope * parent_scope_); + + QueryTreeNodePtr scope_node; + + IdentifierResolveScope * parent_scope = nullptr; + + ContextPtr context; + + /// Identifier lookup to result + std::unordered_map identifier_lookup_to_resolve_state; + + /// Argument can be expression like constant, column, function or table expression + std::unordered_map expression_argument_name_to_node; + + ScopeAliases aliases; + + /// Table column name to column node.

This part is most complex because - * for identifier resolution scopes and identifier lookup context play important part. - * - * ClickHouse SQL support lexical scoping for identifier resolution.

Try to resolve identifier from join tree if scope is query, or if there are registered table columns in scope. - * Steps 2 and 3 can be changed using prefer_column_name_to_alias setting. - * 4. If it is table lookup, try to resolve identifier from CTE. - * If identifier could not be resolved in current scope, resolution must be continued in parent scopes. - * 5. Try to resolve identifier from parent scopes. - * - * Additional rules about aliases and scopes. - * 1. Parent scope cannot refer alias from child scope. - * 2. Child scope can refer to alias in parent scope. - * - * Example: SELECT arrayMap(x -> x + 1 AS a, [1,2,3]), a; Identifier a is unknown in parent scope. - * Example: SELECT a FROM (SELECT 1 as a); Here we do not refer to alias a from child query scope.

This is done this way - * because after identifier node is resolved we lose information about identifier name. We could - * potentially save this information in query tree node itself, but that would require to clone it in some cases. - * Example: SELECT big_scalar_subquery AS a, a AS b, b AS c; - * All 3 nodes in projection are the same big_scalar_subquery, but they have different projection names. - * If we want to save it in query tree node, we have to clone subquery node that could lead to performance degradation. - * - * Possible solution is to separate query node metadata and query node content. So only node metadata could be cloned - * if we want to change projection name. This solution does not seem to be easy for client of query tree because projection - * name will be part of interface. If we potentially could hide projection names calculation in analyzer without introducing additional - * changes in query tree structure that would be preferable. - * - * Currently each resolve method returns projection names array. Resolve method must compute projection names of node. - * If node is resolved as list node this is case for `untuple` function or `matcher` result projection names array must contain projection names - * for result nodes. - * If node is not resolved as list node, projection names array contain single projection name for node. - * - * Rules for projection names: - * 1. If node has alias. It is node projection name. - * Except scenario where `untuple` function has alias. Example: SELECT untuple(expr) AS alias, alias. - * - * 2. For constant it is constant value string representation. - * - * 3. For identifier: - * If identifier is resolved from JOIN TREE, we want to remove additional identifier qualifications. - * Example: SELECT default.test_table.id FROM test_table. - * Result projection name is `id`. - * - * Example: SELECT t1.id FROM test_table_1 AS t1, test_table_2 AS t2 - * In example both test_table_1, test_table_2 have `id` column. - * In such case projection name is `t1.id` because if additional qualification is removed then column projection name `id` will be ambiguous. - * - * Example: SELECT default.test_table_1.id FROM test_table_1 AS t1, test_table_2 AS t2 - * In such case projection name is `test_table_1.id` because we remove unnecessary database qualification, but table name qualification cannot be removed - * because otherwise column projection name `id` will be ambiguous. - * - * If identifier is not resolved from JOIN TREE. Identifier name is projection name. - * Except scenario where `untuple` function resolved using identifier. Example: SELECT untuple(expr) AS alias, alias. - * Example: SELECT sum(1, 1) AS value, value. - * In such case both nodes have `value` projection names. - * - * Example: SELECT id AS value, value FROM test_table. - * In such case both nodes have have `value` projection names. - * - * Special case is `untuple` function. If `untuple` function specified with alias, then result nodes will have alias.tuple_column_name projection names. - * Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value) AS a; - * Result projection names are `value`, `a.id`. - * - * If `untuple` function does not have alias then result nodes will have `tupleElement(untuple_expression_projection_name, 'tuple_column_name') projection names. - * - * Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value); - * Result projection names are `value`, `tupleElement(value, 'id')`; - * - * 4. For function: - * Projection name consists from function_name(parameters_projection_names)(arguments_projection_names). - * Additionally if function is window function. Window node projection name is used with OVER clause. - * Example: function_name (parameters_names)(argument_projection_names) OVER window_name; - * Example: function_name (parameters_names)(argument_projection_names) OVER (PARTITION BY id ORDER BY id). - * Example: function_name (parameters_names)(argument_projection_names) OVER (window_name ORDER BY id). - * - * 5. For lambda: - * If it is standalone lambda that returns single expression, function projection name is used. - * Example: WITH (x -> x + 1) AS lambda SELECT lambda(1). - * Projection name is `lambda(1)`. - * - * If is it standalone lambda that returns list, projection names of list nodes are used. - * Example: WITH (x -> *) AS lambda SELECT lambda(1) FROM test_table; - * If test_table has two columns `id`, `value`. Then result projection names are `id`, `value`. - * - * If lambda is argument of function. - * Then projection name consists from lambda(tuple(lambda_arguments)(lambda_body_projection_name)); - * - * 6. For matcher: - * Matched nodes projection names are used as matcher projection names. - * - * Matched nodes must be qualified if needed. - * Example: SELECT * FROM test_table_1 AS t1, test_table_2 AS t2. - * In example table test_table_1 and test_table_2 both have `id`, `value` columns. - * Matched nodes after unqualified matcher resolve must be qualified to avoid ambiguous projection names. - * Result projection names must be `t1.id`, `t1.value`, `t2.id`, `t2.value`. - * - * There are special cases - * 1. For lambda inside APPLY matcher transformer: - * Example: SELECT * APPLY x -> toString(x) FROM test_table. - * In such case lambda argument projection name `x` will be replaced by matched node projection name. - * If table has two columns `id` and `value`. Then result projection names are `toString(id)`, `toString(value)`; - * - * 2. For unqualified matcher when JOIN tree contains JOIN with USING. - * Example: SELECT * FROM test_table_1 AS t1 INNER JOIN test_table_2 AS t2 USING(id); - * Result projection names must be `id`, `t1.value`, `t2.value`. - * - * 7. For subquery: - * For subquery projection name consists of `_subquery_` prefix and implementation specific unique number suffix. - * Example: SELECT (SELECT 1), (SELECT 1 UNION DISTINCT SELECT 1); - * Result projection name can be `_subquery_1`, `subquery_2`; - * - * 8. For table: - * Table node can be used in expression context only as right argument of IN function. In that case identifier is used - * as table node projection name. - * Example: SELECT id IN test_table FROM test_table; - * Result projection name is `in(id, test_table)`. - */ -using ProjectionName = String; -using ProjectionNames = std::vector; -constexpr auto PROJECTION_NAME_PLACEHOLDER = "__projection_name_placeholder"; + auto options = SelectQueryOptions(QueryProcessingStage::Complete, scope.subquery_depth, true /*is_subquery*/); + options.only_analyze = only_analyze; + auto interpreter = std::make_unique(node->toAST(), subquery_context, subquery_context->getViewSource(), options); -struct IdentifierResolveScope -{ - /// Construct identifier resolve scope using scope node, and parent scope - IdentifierResolveScope(QueryTreeNodePtr scope_node_, IdentifierResolveScope * parent_scope_) - : scope_node(std::move(scope_node_)) - , parent_scope(parent_scope_) - { - if (parent_scope) + if (only_analyze) { - subquery_depth = parent_scope->subquery_depth; - context = parent_scope->context; - projection_mask_map = parent_scope->projection_mask_map; + /// If query is only analyzed, then constants are not correct. + scalar_block = interpreter->getSampleBlock(); + for (auto & column : scalar_block) + { + if (column.column->empty()) + { + auto mut_col = column.column->cloneEmpty(); + mut_col->insertDefault(); + column.column = std::move(mut_col); + } + } } else - projection_mask_map = std::make_shared>(); - - if (auto * union_node = scope_node->as()) - { - context = union_node->getContext(); - } - else if (auto * query_node = scope_node->as()) { - context = query_node->getContext(); - group_by_use_nulls = context->getSettingsRef().group_by_use_nulls && - (query_node->isGroupByWithGroupingSets() || query_node->isGroupByWithRollup() || query_node->isGroupByWithCube()); - } - - if (context) - join_use_nulls = context->getSettingsRef().join_use_nulls; - else if (parent_scope) - join_use_nulls = parent_scope->join_use_nulls; - - aliases.alias_name_to_expression_node = &aliases.alias_name_to_expression_node_before_group_by; - } - - QueryTreeNodePtr scope_node; - - IdentifierResolveScope * parent_scope = nullptr; - - ContextPtr context; - - /// Identifier lookup to result - std::unordered_map identifier_lookup_to_resolve_state; - - /// Argument can be expression like constant, column, function or table expression - std::unordered_map expression_argument_name_to_node; + auto io = interpreter->execute(); + PullingAsyncPipelineExecutor executor(io.pipeline); + io.pipeline.setProgressCallback(context->getProgressCallback()); + io.pipeline.setProcessListElement(context->getProcessListElement()); - ScopeAliases aliases; + Block block; - /// Table column name to column node.
