# generate_series
|
||
|
||
`generate_series(START, STOP)` - Returns a table with the single ‘generate_series’ column (UInt64) that contains integers from start to stop inclusively.
|
||
|
||
`generate_series(START, STOP, STEP)` - Returns a table with the single ‘generate_series’ column (UInt64) that contains integers from start to stop inclusively with spacing between values given by STEP.
|
||
|
||
The following queries return tables with the same content but different column names:
|
||
|
||
``` sql
|
||
SELECT * FROM numbers(10, 5);
|
||
SELECT * FROM generate_series(10, 14);
|
||
```
|
||
|
||
And the following queries return tables with the same content but different column names (but the second option is more efficient):
|
||
|
||
``` sql
|
||
SELECT * FROM numbers(10, 11) WHERE number % 3 == (10 % 3);
|
||
SELECT * FROM generate_series(10, 20, 3) ;
|
||
