![]() ![]() Note that Information Schema queries lacking sufficiently selective filters return an error and do not execute (see General Usage Notes in this topic). To query against a particular schema, you must use a filter predicate (e.g. It is intuitive, quick, and easy to use, lowering the barriers to capturing important information about your databases. Views display all objects in the current/specified database. Database Note Taker is a simple and focused tool that makes database documentation quite handy. Most SHOW commands limit results to the current schema by default. Snowflake automatically converts unquoted, case-insensitive identifiers to uppercase internally, so unquoted object names must be queried in uppercase in the Information Schema views. Warehouse must be running and currently in use to query the views.Ĭase-insensitive (when filtering using LIKE). Formal metadata is not always necessary, as long as all the needed information is included in a readme file, data dictionary, or other open format. You can use the views to replace these commands however, there are some key differences to consider before switching: Spreadsheet- Quick and easy but not a good solution for the long term. First, here’s a summary of your options: 1. ![]() The INFORMATION_SCHEMA views provides a SQL interface to the same information provided by the SHOW commands. Now that you’ve seen all the tool options available: let’s look at some guidelines for developing a data dictionary. Returns results if role has been assigned the MONITOR USAGE global privilege otherwise, returns results only for the ACCOUNTADMIN role.Ĭonsiderations for Replacing SHOW Commands with Information Schema Views ¶ Results returned only for the ACCOUNTADMIN role or task owner (role with OWNERSHIP privilege on task). Results are only returned for the role that has access to the specified object. STAGE_DIRECTORY_FILE_REGISTRATION_HISTORY Results depend on the MONITOR USAGE privilege. REPLICATION_GROUP_REFRESH_PROGRESS, REPLICATION_GROUP_REFRESH_PROGRESS_BY_JOB Results are only returned for a role with any privilege on the replication or failover group. the role with the OWNERSHIP privilege on the integration) or a role with the USAGE privilege on the integration. Results returned only for the ACCOUNTADMIN role, the integration owner (i.e. Results returned only for the ACCOUNTADMIN role. Results depend on the privileges assigned to the user’s current role.ĭATABASE_REFRESH_PROGRESS, DATABASE_REFRESH_PROGRESS_BY_JOB the role with the OWNERSHIP privilege on the task), or a role with the global MONITOR EXECUTION privilege. Define relationships across databases and data sets. Results returned only for the ACCOUNTADMIN role, the task owner (i.e. Dataedo reads foreign keys from the database to the data dictionary, allows you to extend this information with manually defined relationships, and visualizes them with ER diagrams. Results depend on MONITOR USAGE privilege. The underlying DataDictionary object can be used to output the data dictionary in customised ways, such as an ASP.NET page or as part of an API.The table functions in INFORMATION_SCHEMA can be used to return account-level usage and historical information for storage, warehouses, The library contains built-in outputs to:
