	### Dataset Summary

	A large crowd-sourced dataset for developing natural language interfaces for relational databases.

	WikiSQL is a dataset of 80654 hand-annotated examples
	of questions and SQL queries distributed across 24241 tables from Wikipedia.

	### Supported Tasks and Leaderboards

	## Dataset Structure

	### Data Instances

	#### default

	- Size of downloaded dataset files: 26.16 MB
	- Size of the generated dataset: 154.74 MB
	- Total amount of disk used: 180.90 MB

	An example of 'validation' looks as follows.
	```
	This example was too long and was cropped:

	{
	"phase": 1,
	"question": "How would you answer a second test question?",
	"sql": {
	"agg": 0,
	"conds": {
	"column_index": [2],
	"condition": ["Some Entity"],
	"operator_index": [0]
	},
	"human_readable": "SELECT Header1 FROM table WHERE Another Header = Some Entity",
	"sel": 0
	},
	"table": "{\"caption\": \"L\", \"header\": [\"Header1\", \"Header 2\", \"Another Header\"], \"id\": \"1-10015132-9\", \"name\": \"table_10015132_11\", \"page_i..."
	}
	```

	### Data Fields

	The data fields are the same among all splits.

	#### default
	- `phase`: a `int32` feature.
	- `question`: a `string` feature.
	- `header`: a `list` of `string` features.
	- `page_title`: a `string` feature.
	- `page_id`: a `string` feature.
	- `types`: a `list` of `string` features.
	- `id`: a `string` feature.
	- `section_title`: a `string` feature.
	- `caption`: a `string` feature.
	- `rows`: a dictionary feature containing:
	- `feature`: a `string` feature.
	- `name`: a `string` feature.
	- `human_readable`: a `string` feature.
	- `sel`: a `int32` feature.
	- `agg`: a `int32` feature.
	- `conds`: a dictionary feature containing:
	- `column_index`: a `int32` feature.
	- `operator_index`: a `int32` feature.
	- `condition`: a `string` feature.
