I just make this updated and manually tested the jdbc datasource with h2
database as below
with "text.json" below:
```json
{"name": "bcd"}
{"name": "abc"}
{"name": "Hyukjin"}
```
with the codes below:
```r
> df <- read.df(source="jdbc",
+ driver="org.h2.Driver",
+ url="jdbc:h2:mem:testdb0;user=testUser;password=testPass",
+ dbtable="PEOPLE")
> collect(df)
NAME
1 fred
2 mary
> jsonDF <- read.json("test.json")
> write.df(jsonDF,
+ source = "jdbc",
+ mode = "overwrite",
+ driver = "org.h2.Driver",
+ url = "jdbc:h2:mem:testdb0;user=testUser;password=testPass",
+ dbtable = "PEOPLE")
> readback <- read.df(source = "jdbc",
+ driver = "org.h2.Driver",
+ url =
"jdbc:h2:mem:testdb0;user=testUser;password=testPass",
+ dbtable = "PEOPLE")
