## Recursive Queries
The optional RECURSIVE modifier allows for a WITH query to refer to its own output. Example:
**Example:** Sum integers from 1 through 100
```sql
WITH RECURSIVE test_table AS (
SELECT 1 AS number
UNION ALL
SELECT number + 1 FROM test_table WHERE number < 100
)
SELECT sum(number) FROM test_table;
```
``` text
┌─sum(number)─┐
│ 5050 │
└─────────────┘
```
The general form of a recursive `WITH` query is always a non-recursive term, then `UNION ALL`, then a recursive term, where only the recursive term can contain a reference to the query's own output. Recursive CTE query is executed as follows:
1. Evaluate the non-recursive term. Place result of non-recursive term query in a temporary working table.
2. As long as the working table is not empty, repeat these steps:
1. Evaluate the recursive term, substituting the current contents of the working table for the recursive self-reference. Place result of recursive term query in a temporary intermediate table.
2. Replace the contents of the working table with the contents of the intermediate table, then empty the intermediate table.
Recursive queries are typically used to work with hierarchical or tree-structured data. For example, we can write a query that performs tree traversal:
**Example:** Tree traversal
First let's create tree table:
```sql
DROP TABLE IF EXISTS tree;
CREATE TABLE tree
(
id UInt64,
parent_id Nullable(UInt64),
data String
) ENGINE = MergeTree ORDER BY id;
INSERT INTO tree VALUES (0, NULL, 'ROOT'), (1, 0, 'Child_1'), (2, 0, 'Child_2'), (3, 1, 'Child_1_1');
```
We can traverse those tree with such query:
**Example:** Tree traversal
```sql
WITH RECURSIVE search_tree AS (
SELECT id, parent_id, data
FROM tree t
WHERE t.id = 0
UNION ALL
SELECT t.id, t.parent_id, t.data
FROM tree t, search_tree st
WHERE t.parent_id = st.id
)
SELECT * FROM search_tree;
```
```text
┌─id─┬─parent_id─┬─data──────┐
│ 0 │ ᴺᵁᴸᴸ │ ROOT │
│ 1 │ 0 │ Child_1 │
│ 2 │ 0 │ Child_2 │
│ 3 │ 1 │ Child_1_1 │
└────┴───────────┴───────────┘
```
### Search order
To create a depth-first order, we compute for each result row an array of rows that we have already visited:
**Example:** Tree traversal depth-first order
```sql
WITH RECURSIVE search_tree AS (
SELECT id, parent_id, data, [t.id] AS path
FROM tree t
WHERE t.id = 0
UNION ALL
SELECT t.id, t.parent_id, t.data, arrayConcat(path, [t.id])
FROM tree t, search_tree st
WHERE t.parent_id = st.id
)
SELECT * FROM search_tree ORDER BY path;
```
```text
┌─id─┬─parent_id─┬─data──────┬─path────┐
│ 0 │ ᴺᵁᴸᴸ │ ROOT │ [0] │
│ 1 │ 0 │ Child_1 │ [0,1] │
│ 3 │ 1 │ Child_1_1 │ [0,1,3] │
│ 2 │ 0 │ Child_2 │ [0,2] │
└────┴───────────┴───────────┴─────────┘
```
To create a breadth-first order, standard approach is to add column that tracks the depth of the search:
**Example:** Tree traversal breadth-first order
```sql
WITH RECURSIVE search_tree AS (
SELECT id, parent_id, data, [t.id] AS path, toUInt64(0) AS depth
FROM tree t
WHERE t.id = 0
UNION ALL
SELECT t.id, t.parent_id, t.data, arrayConcat(path, [t.id]), depth + 1
FROM tree t, search_tree st
WHERE t.parent_id = st.id
)
SELECT * FROM search_tree ORDER BY depth;
```
```text
┌─id─┬─link─┬─data──────┬─path────┬─depth─┐
│ 0 │ ᴺᵁᴸᴸ │ ROOT │ [0] │ 0 │
│ 1 │ 0 │ Child_1 │ [0,1] │ 1 │
│ 2 │ 0 │ Child_2 │ [0,2] │ 1 │
│ 3 │ 1 │ Child_1_1 │ [0,1,3] │ 2 │
└────┴──────┴───────────┴─────────┴───────┘
```
### Cycle detection
First let's create graph table:
```sql
DROP TABLE IF EXISTS graph;
CREATE TABLE graph
(
from UInt64,
to UInt64,
label String
) ENGINE = MergeTree ORDER BY (from, to);
INSERT INTO graph VALUES (1, 2, '1 -> 2'), (1, 3, '1 -> 3'), (2, 3, '2 -> 3'), (1, 4, '1 -> 4'), (4, 5, '4 -> 5');
```
We can traverse that graph with such query:
**Example:** Graph traversal without cycle detection
```sql
WITH RECURSIVE search_graph AS (
SELECT from, to, label FROM graph g
UNION ALL
SELECT g.from, g.to, g.label
FROM graph g, search_graph sg
WHERE g.from = sg.to
)
SELECT DISTINCT * FROM search_graph ORDER BY from;
```
```text
┌─from─┬─to─┬─label──┐
│ 1 │ 4 │ 1 -> 4 │
│ 1 │ 2 │ 1 -> 2 │
│ 1 │ 3 │ 1 -> 3 │
│ 2 │ 3 │ 2 -> 3 │
│ 4 │ 5 │ 4 -> 5 │
└──────┴────┴────────┘
```
But if we add cycle in that graph, previous query will fail with `Maximum recursive CTE evaluation depth` error:
```sql
INSERT INTO graph VALUES (5, 1, '5 -> 1');
WITH RECURSIVE search_graph AS (
SELECT from, to, label FROM graph g
UNION ALL
SELECT g.from, g.to, g.label
FROM graph g, search_graph sg
WHERE g.from = sg.to
)
SELECT DISTINCT * FROM search_graph ORDER BY from;
```
```text
Code: 306. DB::Exception: Received from localhost:9000. DB::Exception: Maximum recursive CTE evaluation depth (1000) exceeded, during evaluation of search_graph AS (SELECT from, to, label FROM graph AS g UNION ALL SELECT g.from, g.to, g.label FROM graph AS g, search_graph AS sg WHERE g.from = sg.to). Consider raising max_recursive_cte_evaluation_depth setting.: While executing RecursiveCTESource. (TOO_DEEP_RECURSION)
```
The standard method for handling cycles is to compute an array of the already visited nodes:
**Example:** Graph traversal with cycle detection
```sql
WITH RECURSIVE search_graph AS (
SELECT from, to, label, false AS is_cycle, [tuple(g.from, g.to)] AS path FROM graph g
UNION ALL
SELECT g.from, g.to, g.label, has(path, tuple(g.from, g.to)), arrayConcat(sg.path, [tuple(g.from, g.to)])
FROM graph g, search_graph sg
WHERE g.from = sg.to AND NOT is_cycle
)
SELECT * FROM search_graph WHERE is_cycle ORDER BY from;
```
```text
┌─from─┬─to─┬─label──┬─is_cycle─┬─path──────────────────────┐
│ 1 │ 4 │ 1 -> 4 │ true │ [(1,4),(4,5),(5,1),(1,4)] │
│ 4 │ 5 │ 4 -> 5 │ true │ [(4,5),(5,1),(1,4),(4,5)] │
│ 5 │ 1 │ 5 -> 1 │ true │ [(5,1),(1,4),(4,5),(5,1)] │
└──────┴────┴────────┴──────────┴───────────────────────────┘
```
### Infinite queries
It is also possible to use infinite recursive CTE queries if `LIMIT` is used in outer query:
**Example:** Infinite recursive CTE query
```sql
WITH RECURSIVE test_table AS (
SELECT 1 AS number
UNION ALL
SELECT number + 1 FROM test_table
)
SELECT sum(number) FROM (SELECT number FROM test_table LIMIT 100);
```
```text
┌─sum(number)─┐
│ 5050 │
└─────────────┘
```

# Nullable处理函数 {#nullablechu-li-han-shu}
## isNull {#isnull}
检查参数是否为[NULL](../../sql-reference/syntax.md#null-literal)。
isNull(x)
**参数**
- `x` — 一个非复合数据类型的值。
**返回值**
- `1` 如果`x`为`NULL`。
- `0` 如果`x`不为`NULL`。
**示例**
存在以下内容的表
```response
┌─x─┬────y─┐
│ 1 │ ᴺᵁᴸᴸ │
│ 2 │ 3 │
└───┴──────┘
```
对其进行查询
```sql
SELECT x FROM t_null WHERE isNull(y)
```
```response
┌─x─┐
│ 1 │
└───┘
```
## isNotNull {#isnotnull}
检查参数是否不为 [NULL](../../sql-reference/syntax.md#null-literal).
isNotNull(x)
**参数:**
- `x` — 一个非复合数据类型的值。
**返回值**
- `0` 如果`x`为`NULL`。
- `1` 如果`x`不为`NULL`。
**示例**
存在以下内容的表
```response
┌─x─┬────y─┐
│ 1 │ ᴺᵁᴸᴸ │
│ 2 │ 3 │
└───┴──────┘
```
对其进行查询
```sql
SELECT x FROM t_null WHERE isNotNull(y)
```
```response
┌─x─┐
│ 2 │
└───┘
```
## 合并 {#coalesce}
检查从左到右是否传递了«NULL»参数并返回第一个非`'NULL`参数。
coalesce(x,...)
**参数:**
- 任何数量的非复合类型的参数。所有参数必须与数据类型兼容。
**返回值**
- 第一个非NULL\`参数。
- `NULL`如果所有参数都是NULL\`。
**示例**
考虑可以指定多种联系客户的方式的联系人列表。
```response
┌─name─────┬─mail─┬─phone─────┬──icq─┐
│ client 1 │ ᴺᵁᴸᴸ │ 123-45-67 │ 123 │
│ client 2 │ ᴺᵁᴸᴸ │ ᴺᵁᴸᴸ │ ᴺᵁᴸᴸ │
└──────────┴──────┴───────────┴──────┘
```
`mail`和`phone`字段是String类型但`icq`字段是`UInt32`,所以它需要转换为`String`。
从联系人列表中获取客户的第一个可用联系方式:
```sql
SELECT coalesce(mail, phone, CAST(icq,'Nullable(String)')) FROM aBook
```
```response
┌─name─────┬─coalesce(mail, phone, CAST(icq, 'Nullable(String)'))─┐
│ client 1 │ 123-45-67 │
│ client 2 │ ᴺᵁᴸᴸ │
└──────────┴──────────────────────────────────────────────────────┘
```
## ifNull {#ifnull}
如果第一个参数为«NULL»则返回第二个参数的值。
ifNull(x,alt)
**参数:**
- `x` — 要检查«NULL»的值。
- `alt` — 如果`x`为NULL\`,函数返回的值。
**返回值**
- 价值 `x`,如果 `x` 不是 `NULL`.
- 价值 `alt`,如果 `x``NULL`.
**示例**
SELECT ifNull('a', 'b')
┌─ifNull('a', 'b')─┐
│ a │
└──────────────────┘
SELECT ifNull(NULL, 'b')
┌─ifNull(NULL, 'b')─┐
│ b │
└───────────────────┘
## nullIf {#nullif}
如果参数相等,则返回`NULL`。
nullIf(x, y)
**参数:**
`x`, `y` — 用于比较的值。 它们必须是类型兼容的,否则将抛出异常。
**返回值**
- 如果参数相等,则为`NULL`。
- 如果参数不相等,则为`x`值。
**示例**
SELECT nullIf(1, 1)
┌─nullIf(1, 1)─┐
│ ᴺᵁᴸᴸ │
└──────────────┘
SELECT nullIf(1, 2)
┌─nullIf(1, 2)─┐
│ 1 │
└──────────────┘
## assumeNotNull {#assumenotnull}
将[可为空](../../sql-reference/functions/functions-for-nulls.md)类型的值转换为非`Nullable`类型的值。
assumeNotNull(x)
**参数:**
- `x` — 原始值。
**返回值**
- 如果`x`不为`NULL`,返回非`Nullable`类型的原始值。
- 如果`x`为`NULL`,则返回任意值。
**示例**
存在如下`t_null`表。
SHOW CREATE TABLE t_null
┌─statement─────────────────────────────────────────────────────────────────┐
│ CREATE TABLE default.t_null ( x Int8, y Nullable(Int8)) ENGINE = TinyLog │
└───────────────────────────────────────────────────────────────────────────┘
┌─x─┬────y─┐
│ 1 │ ᴺᵁᴸᴸ │
│ 2 │ 3 │
└───┴──────┘
将列`y`作为`assumeNotNull`函数的参数。
SELECT assumeNotNull(y) FROM t_null
┌─assumeNotNull(y)─┐
│ 0 │
│ 3 │
└──────────────────┘
SELECT toTypeName(assumeNotNull(y)) FROM t_null
┌─toTypeName(assumeNotNull(y))─┐
│ Int8 │
│ Int8 │
└──────────────────────────────┘
## 可调整 {#tonullable}
将参数的类型转换为`Nullable`。
toNullable(x)
**参数:**
- `x` — 任何非复合类型的值。
**返回值**
- 输入的值,但其类型为`Nullable`。
**示例**
SELECT toTypeName(10)
┌─toTypeName(10)─┐
│ UInt8 │
└────────────────┘
SELECT toTypeName(toNullable(10))
┌─toTypeName(toNullable(10))─┐
│ Nullable(UInt8) │
