Method Detail

setRoutineType

public abstract RoutineInfo.Builder setRoutineType(String routineType)

Sets the routine type for the Builder (e.g. SCALAR_FUNCTION).

See https://cloud.google.com/bigquery/docs/reference/rest/v2/routines

setLanguage

public abstract RoutineInfo.Builder setLanguage(String language)

Sets the language for the routine (e.g. SQL or JAVASCRIPT)

setArguments

public abstract RoutineInfo.Builder setArguments(List<RoutineArgument> argumentList)

Specifies the list of input/output arguments for the routine.

setReturnType

public abstract RoutineInfo.Builder setReturnType(StandardSQLDataType returnType)

Sets the return type of the routine.

Optional if language = "SQL"; required otherwise.

If absent, the return type is inferred from definitionBody at query time in each query that references this routine. If present, then the evaluated result will be cast to the specified returned type at query time.

setImportedLibraries

public abstract RoutineInfo.Builder setImportedLibraries(List<String> importedLibrariesList)

Optional. If language = "JAVASCRIPT", this field stores the path of the imported JAVASCRIPT libraries as a list of gs:// URLs.

setBody

public abstract RoutineInfo.Builder setBody(String body)

Required. The body of the routine.

For functions, this is the expression in the AS clause.

If language=SQL, it is the substring inside (but excluding) the parentheses. For example, for the function created with the following statement:

CREATE FUNCTION JoinLines(x string, y string) as (concat(x, "\n", y))

The definitionBody is concat(x, "\n", y) (\n is not replaced with linebreak).

If language=JAVASCRIPT, it is the evaluated string in the AS clause. For example, for the function created with the following statement:

CREATE FUNCTION f() RETURNS STRING LANGUAGE js AS 'return "\n";\n'

The definitionBody is

return "\n";\n

Note that both \n are replaced with linebreaks.

build

public abstract RoutineInfo build()

Creates a RoutineInfo object.
