Arguments

:: Text	`$sel:name:Column'`
-> Column

Create a value of Column with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:parameters:Column', column_parameters - These key-value pairs define properties associated with the column.

$sel:type':Column', column_type - The data type of the Column.

$sel:comment:Column', column_comment - A free-form text comment.

$sel:name:Column', column_name - The name of the Column.

column_parameters :: Lens' Column (Maybe (HashMap Text Text)) Source #

These key-value pairs define properties associated with the column.

column_type :: Lens' Column (Maybe Text) Source #

The data type of the Column.

column_comment :: Lens' Column (Maybe Text) Source #

A free-form text comment.

column_name :: Lens' Column Text Source #

The name of the Column.
