Fonction values - module sqlalchemy

Signature de la fonction values

def values(*columns: 'ColumnClause[Any]', name: 'Optional[str]' = None, literal_binds: 'bool' = False) -> 'Values' 

Description

help(sqlalchemy.values)

Construct a :class:`_expression.Values` construct.

The column expressions and the actual data for
:class:`_expression.Values` are given in two separate steps.  The
constructor receives the column expressions typically as
:func:`_expression.column` constructs,
and the data is then passed via the
:meth:`_expression.Values.data` method as a list,
which can be called multiple
times to add more data, e.g.::

    from sqlalchemy import column
    from sqlalchemy import values

    value_expr = values(
        column("id", Integer),
        column("name", String),
        name="my_values",
    ).data([(1, "name1"), (2, "name2"), (3, "name3")])

:param \*columns: column expressions, typically composed using
 :func:`_expression.column` objects.

:param name: the name for this VALUES construct.  If omitted, the
 VALUES construct will be unnamed in a SQL expression.   Different
 backends may have different requirements here.

:param literal_binds: Defaults to False.  Whether or not to render
 the data values inline in the SQL output, rather than using bound
 parameters.
