# Good Query
This query is the same as the above, but note the constraint in the code.

```R
 im <- initInterMine(mine=listMines()["HumanMine"])
 queryGeneOrth = getTemplateQuery(
     im = im,
     name = "Gene_Orth"
 )
 newConstraint <- list(
     path=c("Gene.homologues.homologue.organism.shortName"),
     op=c("!="),
     value=c("H. sapiens"),
     code=c("B")
 )
 queryGeneOrth$where[[2]] <- newConstraint
 resGeneOrth <- runQuery(im, queryGeneOrth)
```

# Bad Query
This query is bad because it's missing a constraint code. It'll make InterMine return a 400 error.

```R
 im <- initInterMine(mine=listMines()["HumanMine"])
 queryGeneOrth = getTemplateQuery(
     im = im,
     name = "Gene_Orth"
 )
 newConstraint <- list(
     path=c("Gene.homologues.homologue.organism.shortName"),
     op=c("!="),
     value=c("H. sapiens")
 )
 queryGeneOrth$where[[2]] <- newConstraint
 resGeneOrth <- runQuery(im, queryGeneOrth)
```
