data ResultSetMetadata = ResultSetMetadata' {
- columnInfo :: Maybe [ColumnInfo]
}
newResultSetMetadata :: ResultSetMetadata
resultSetMetadata_columnInfo :: Lens' ResultSetMetadata (Maybe [ColumnInfo])

newResultSetMetadata :: ResultSetMetadata Source #

Create a value of ResultSetMetadata 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:columnInfo:ResultSetMetadata', resultSetMetadata_columnInfo - Information about the columns returned in a query result metadata.

resultSetMetadata_columnInfo :: Lens' ResultSetMetadata (Maybe [ColumnInfo]) Source #

Information about the columns returned in a query result metadata.
