INDEX Creation problem : " instead of `

Syntax error in INDEX or PRIMARY KEY creation :

Should be :

```
ALTER TABLE street
    ADD CONSTRAINT street_pkey PRIMARY KEY (`StrId`);
ALTER TABLE `street` ADD INDEX ( `AdmId` ) ;
```

instead of

```
ALTER TABLE street
    ADD CONSTRAINT street_pkey PRIMARY KEY ("StrId");
ALTER TABLE `street` ADD INDEX ( "AdmId" ) ;
```
