SELECT owner, table_name
FROM dba_tables
This is assuming that you have access to the DBA_TABLES
data dictionary view. 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). 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.
Alternatively, 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_name
FROM all_tables
Although, 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 are only concerned with the tables that you own, not those that you have access to, you could use USER_TABLES
:
SELECT table_name
FROM user_tables
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.
Oracle also has a number of legacy data dictionary views-- TAB
, DICT
, TABS
, and CAT
for example-- that could be used. In general, I would not suggest using these legacy views unless you absolutely need to backport your scripts to Oracle 6. Oracle has not changed these views in a long time so they often have problems with newer types of objects. For example, the TAB
and CAT
views both show information about tables that are in the user's recycle bin while the [DBA|ALL|USER]_TABLES
views all filter those out. CAT
also shows information about materialized view logs with a TABLE_TYPE
of "TABLE" which is unlikely to be what you really want. DICT
combines tables and synonyms and doesn't tell you who owns the object.
Are you using Oracle's ODBC driver, or Microsoft?
Stick with the Oracle driver.
Try using your simple test case with a text parameter instead of an integer. Without seeing your code, it could be that you need to pass in a long int to the procedure. Trying a simple text parameter could verify that the problem is in variable typing.

It is possible to search through object code-- you'd generally use the DBMS_METADATA package to generate the DDL for the object and then search the CLOB. However, it doesn't sound like that's actually what you want to do.
If you are just trying to figure out whether a table is referenced by any code in your system, you would generally want to use the
DBA_DEPENDENCIES
view (orALL_DEPENDENCIES
orUSER_DEPENDENCIES
depending on your privileges and the scope of what you're looking for). Something likewill show you everything that depends on the
EMP
table in theSCOTT
schema.The only time you'd want to search code rather than looking at
DBA_DEPENDENCIES
would be when you had code that was doing dynamic SQL where the table name was hard-coded. But that's relatively unlikely in practice.
