## toCustomWeek
|
||||
## week(date[,mode])
|
||||
This function returns the week number for date or datetime. The two-argument form of week() enables you to specify whether the week starts on Sunday or Monday and whether the return value should be in the range from 0 to 53 or from 1 to 53. If the mode argument is omitted, the default mode is 0.
|
||||
The following table describes how the mode argument works.
|
||||
|
||||
| Mode | First day of week | Range | Week 1 is the first week … |
|
||||
| ----------- | -------- | -------- | ------------------ |
|
||||
|0|Sunday|0-53|with a Sunday in this year
|
||||
|1|Monday|0-53|with 4 or more days this year
|
||||
|2|Sunday|1-53|with a Sunday in this year
|
||||
|3|Monday|1-53|with 4 or more days this year
|
||||
|4|Sunday|0-53|with 4 or more days this year
|
||||
|5|Monday|0-53|with a Monday in this year
|
||||
|6|Sunday|1-53|with 4 or more days this year
|
||||
|7|Monday|1-53|with a Monday in this year
|
||||
|8|Sunday|1-53|contains January 1
|
||||
|9|Monday|1-53|contains January 1
|
||||
|
||||
For mode values with a meaning of “with 4 or more days this year,” weeks are numbered according to ISO 8601:1988:
|
||||
|
||||
- If the week containing January 1 has 4 or more days in the new year, it is week 1.
|
||||
|
||||
- Otherwise, it is the last week of the previous year, and the next week is week 1.
|
||||
|
||||
For mode values with a meaning of “contains January 1”, the week contains January 1 is week 1. It doesn't matter how many days in the new year the week contained, even if it contained only one day.
|
||||
|
||||
Converts a date or date with time to a UInt8 number containing the Custom Week number.
|
||||
The week number 1 is the first week in year that contains some day, which default to January 1, it can be modify by parameter of function.
|
||||
Week begins at monday.
|
||||
```
|
||||
toCustomWeek(DateTime1, [, CustomDate][, Timezone])
|
||||
week(DateTime1, [, mode][, Timezone])
|
||||
|
||||
```
|
||||
**Parameters**
|
||||
|
||||
- `DateTime1` – Date or DateTime.
|
||||
- `CustomDate` – Optional parameter, default is January 1, format: MM-DD.
|
||||
- `mode` – Optional parameter, Range of values is [0,9], default is 0.
|
||||
- `Timezone` – Optional parameter, it behaves like any other conversion function.
|
||||
|
||||
**Example**
|
||||
By default, the week contains January 1 is the first week:
|
||||
|
||||
``` sql
|
||||
SELECT toDate('2016-12-27') AS date, toCustomYear(date) AS year, toCustomWeek(date) AS week, toStartOfCustomYear(date) AS startday;
|
||||
SELECT toDate('2016-12-27') AS date, week(date) AS week0, week(date,1) AS week1, week(date,9) AS week9;
|
||||
```
|
||||
|
||||
```
|
||||
┌───────date─┬─year─┬─week─┬───startday─┐

||||

|
||||
```
|
||||
|
||||
The week contains January 28 is the first week:
|
||||
## yearWeek(date[,mode])
|
||||
Returns year and week for a date. The year in the result may be different from the year in the date argument for the first and the last week of the year.
|
||||
|
||||
The mode argument works exactly like the mode argument to week(). For the single-argument syntax, a mode value of 0 is used.
|
||||
|
||||
**Example**
|
||||
|
||||
``` sql
|
||||
SELECT toDate('2016-12-27') AS date, toCustomYear(date, '01-28') AS year, toCustomWeek(date,'01-28') AS week, toStartOfCustomYear(date,'01-28') AS startday;
|

SELECT toDate('2016-12-27') AS date, yearWeek(date) AS yearWeek0, yearWeek(date,1) AS yearWeek1, yearWeek(date,9) AS yearWeek9;
