Sometimes `recsel` chokes on a large query, and you need to break the query into chunks with a pipe.
|
|
|
|
This Kickstarter file has 374,853 records.
|
|
Here's the chonky query:
|
|
|
|
```sh
|
|
recsel kick.rec -e "Category = 'Games'" -p "Subcategory,Avg(Goal)" -G Subcategory
|
|
```
|
|
|
|
It breaks down like this:
|
|
|
|
| Chunk | Meaning |
|
|
|:-----------------------------:|:---------------------------------------------:|
|
|
| `recsel kick.rec` | Select records from `kick.rec` |
|
|
| `-e "Category = 'Games'"` | Select only records where Category = 'Games' |
|
|
| `-p "Subcategory,Avg(Goal)"` | Print the Subcategory and average goal |
|
|
| `-G "Subcategory"` | Group by subcategory |
|
|
|
|
Two ways to break the query apart:
|
|
|
|
```sh
|
|
recsel kick.rec -e "Category = 'Games'" | recsel -p "Subcategory,Avg(Goal)" -G "Subcategory"
|
|
|
|
recsel kick.rec -e "Category = 'Games'" > games.rec
|
|
recsel games.rec -p "Subcategory" -G "Subcategory"
|
|
```
