Instance Attribute Details

#prepared_statements_column_defaults ⇒ Object (readonly)

A hash with column symbol keys and default values. Instance’s values are merged into this hash before creating to reduce the number of free columns (columns that may or may not be present in the INSERT statement), as the number of prepared statements that can be created is 2^N (where N is the number of free columns).
