## Example
### DDL (Redshift)
```sql
CREATE TABLE IF NOT EXISTS "sample_schema"."sample_table"
(
	"div_cd" VARCHAR(2) NOT NULL
	,"div_name" VARCHAR(30) NOT NULL
	,"org_cd" VARCHAR(8) NOT NULL
	,"org_name" VARCHAR(60) NOT NULL
	,"team_cd" VARCHAR(2) NOT NULL
	,"team_name" VARCHAR(120) NOT NULL
	,"personal_cd" VARCHAR(7) NOT NULL
	,"personal_name" VARCHAR(300) NOT NULL
	,"username" VARCHAR(6) NOT NULL
	,"staff_flg" CHAR(1)  DEFAULT '0'::bpchar ENCODE lzo
	,"leader_flg" CHAR(1)  DEFAULT '0'::bpchar ENCODE lzo
)
DISTSTYLE EVEN
;
```

### ddlparse output BigQuery JSON schema
Not parse `leader_flg` field.
