How to interprete 'B = T1.A' and 'T1.A AS B' as equivalent? (convert "UnnamedExpr" with "op": "Eq" into "ExprWithAlias")

in views mssqlserver allows 2 ways to define a columns alias. I would like to "normalize" the representation in json. I would like to have the same style in JSON for the same logic. There could be a property to indicate how this was in the original expression to not lost this information.

The best would be, if I could convert the presentation of `B = T1.A` into the presentation of `T1.A AS B`
but it would also be OK to convert `T1.C AS D` into `D = T1.C`

```sql
CREATE VIEW aaa.test01 AS SELECT B = T1.A, T1.C AS D FROM aaa.bbb AS T1
```

Serialized as JSON:
```json
[
{
"CreateView": {
"or_replace": false,
"materialized": false,
"name": [
{
"value": "aaa",
"quote_style": null
},
{
"value": "test01",
"quote_style": null
}
],
"columns": [],
"query": {
"ctes": [],
"body": {
"Select": {
"distinct": false,
"top": null,
"projection": [
{

Commencez par retracer la manière dont l’analyseur SQL représente la forme `UnnamedExpr`/`BinaryOp` et la forme `ExprWithAlias` présentées dans le JSON de l’issue. Définissez comment les alias SQL Server équivalents doivent être normalisés et comment la présentation originale serait préservée, puis vérifiez que les deux exemples de CREATE VIEW sont sérialisés de manière cohérente.

Rédigé par le modèle d'indexation à partir du texte de l'issue.
