• name, value Name and value for a variable.

• name, value, type Name, value and type for a variable.

• name, list(value) Name, list of values.

• name, list(value), list(type) Name, list of values, list of types.

Examples

# NOT RUN {
query_obj <- Query(Session,
  "declare variable $name external; for $i in 1 to 2 return element { $name } { $i }")
Bind(query_obj, "$name", "number")
print(Execute(query_obj))

query_obj <- Query(Session,
  "declare variable $name external; for $i in 3 to 4 return element { $name } { $i }")
Bind(query_obj, "$name", "number", "xs:string")
print(Execute(query_obj))

query_obj <- Query(Session,
  "declare variable $name external;
  for $t in collection('TestDB/Books')/book where $t/@author = $name
  return $t/@title/string()")
Bind(query_obj, "$name", list("Walmsley", "Wickham"))
print(Execute(query_obj))

query_obj <- Query(Session,
  "declare variable $name external;
  for $t in collection('TestDB/Books')/book where $t/@author = $name
