ying-hua opened a new issue, #10962:
URL: https://github.com/apache/inlong/issues/10962
### Description
Currently, SQL statements of Json SourceData in Inlong transform only
support selecting data from key-value pair structures such as
```
{
"sid":"value1",
"msgs":[
{"msg":"1001"},
{"msg":"1002"}
]
}
```
However, it lacks the capability to select data from simple array structures
like {"arr":[1,2,3]}.
### Use case
### case 1
transformSql = "select $root.matrix(0)(1) from source"
jsonString:
```
{
"matrix":[
[1,2,3],
[4,5,6],
[7,8,9]
]
}
```
result: $root.matrix(0)(1)="2"
### case 2
transformSql = "select $root.fruit(0) from source"
jsonString:
```
{
"fruit":["apple", "banana"]
}
```
result: $root.fruit(0)="apple"
### case 3
transformSql = "select $root.arr(1).id, $root.arr(2)(1) from source"
jsonString:
```
{
"arr":[
"value1",
{"id":"1001"},
[12,-3,25]
]
}
```
result: $root.arr(1).id = "1001", $root.arr(2)(1) = "-3"
