Thereafter you may simply pass schema name as an argument SQL> alias tables_schema = select owner, table_name, last_analyzed from all_tables where owner = :ownr If you want to list tables from a specific schema, using a new user-defined alias and passing schema name as a bind argument with only a set of columns being displayed, you may do so using You don't have to define this alias as it comes by default under SQLcl. select table_name "TABLES" from user_tables Tables - tables - show tables from schema To know what the tables alias is referring to, you may simply use alias list SQL > alias list tables

SQL > set sqlformat ansiconsole - resizes the columns to the width of the - data to save space It is recommended to enter this sqlcl specific command before running any other commands or queries which display data. First, connect to a sql command line ( sql.exe in windows) session. Here are few examples showing the usage and additional aspects of the feature.

DICT combines tables and synonyms and doesn't tell you who owns the object.Ī new feature available in SQLcl( which is a free command line interface for Oracle Database) is CAT also shows information about materialized view logs with a TABLE_TYPE of "TABLE" which is unlikely to be what you really want. For example, the TAB and CAT views both show information about tables that are in the user's recycle bin while the _TABLES views all filter those out. Oracle has not changed these views in a long time so they often have problems with newer types of objects. In general, I would not suggest using these legacy views unless you absolutely need to backport your scripts to Oracle 6. Oracle also has a number of legacy data dictionary views- TAB, DICT, TABS, and CAT for example- that could be used. Since USER_TABLES only has information about the tables that you own, it does not have an OWNER column – the owner, by definition, is you. If you are only concerned with the tables that you own, not those that you have access to, you could use USER_TABLES: SELECT table_name Of course, you may want to exclude certain schemas like SYS and SYSTEM which have large numbers of Oracle tables that you probably don't care about.Īlternatively, if you do not have access to DBA_TABLES, you can see all the tables that your account has access to through the ALL_TABLES view: SELECT owner, table_nameĪlthough, that may be a subset of the tables available in the database ( ALL_TABLES shows you the information for all the tables that your user has been granted access to). If you do not have those privileges but need them, you can request that the DBA explicitly grants you privileges on that table, or, that the DBA grants you the SELECT ANY DICTIONARY privilege or the SELECT_CATALOG_ROLE role (either of which would allow you to query any data dictionary table). This is assuming that you have access to the DBA_TABLES data dictionary view.
