Query goal: | Find all the base table columns that have the type timestamp without time zone or timestamp with time zone. Return the data only if there is at least one column with the type timestamp without time zone and one column with the type timestamp with time zone. |
Query type: | Problem detection (Each row in the result could represent a flaw in the design) |
Query reliability: | Medium (Medium number of false-positive results) |

Data source: | INFORMATION_SCHEMA only |

Collection name | Collection description |

Find problems about base tables | A selection of queries that return information about the data types, field sizes, default values as well as general structure of base tables. Contains all the types of queries - problem detection, software measure, and general overview |
Find problems automatically | Queries, that results point to problems in the database. Each query in the collection produces an initial assessment. However, a human reviewer has the final say as to whether there is a problem or not . |
