How to get constraint name and table and column names

Constraints on a table in Oracle can be found using the below views user_constraints: It provides information about constraints owned by the current user. all_constraints: shows information about constraints accessible to the current user, including those owned by other users. dba_constraints: provides information about all constraints in the

echo „select CONSTRAINT_NAME,CONSTRAINT_TYPE,R_CONSTRAINT_NAME,STATUS,DEFERRED,INDEX_NAME from dba_constraints where“>> $ {REBUILDTABLESCRIPT} echo „OWNER=upper (‚$ {OWNER}‘) and TABLE_NAME=upper (‚$ {OBJECT_NAME}‘) order by CONSTRAINT_TYPE;“

It uses sub-queries to add r_table_name and r_column_name to user_constraints, and then uses them to connect rows. Adjust the where clause to your needs. To get this to work, either run these queries as sys/system, change the quries to use the user_% or all_% views instead of sys_% views, or give the user these 2 privileges: Show All Oracle Database Table Constraints using dba_constraints This article delves into the world of Oracle Database constraints, empowering you to understand their types, statuses, and modification history. We’ll dissect a powerful SQL query that retrieves this crucial information, making you a database management pro. Sample SQL Command

DBA_CONSTRAINTS describes all constraint definitions on all tables in the database. Its columns are the same as those in ALL_CONSTRAINTS. SQL – CONSTRAINTS What are constraints in SQL? SQL constraints define rules for the data in a table. Constraints are used to limit the kind of data that can be entered into a table. This ensures that the table’s data is accurate and reliable. Types of Constraints : Domain Integrity Constraints —- Not null, Check, Default Entity Integrity Constraints —– Unique, Primary Key Referential

In Oracle, a foreign key is a column that references a primary key in another table. It is used to establish a relationship between two tables and ensure data integrity. To check foreign key constraints in Oracle, you can use the following steps: The view V1 is created with ‚WITH READ ONLY‘ (hence a record exist in DBA_CONSTRAINTS with CONSTRAINT_TYPE=’O‘) where are the view V2 has the same defination as V1 but is without ‚WITH READ ONLY‘. How can I alter view V2 without dropping so that it is similar to V1 (‚WITH READ ONLY‘) and thereby a record exist in DBA_CONSTRAINTS

Following the release of Oracle 19c, many Oracle customers planned to migrate their older DBs especially the widely used version „11g“ to 19c. Because of the restrictions on the direct upgrade from 11g to 19c, data pump method became the optimal method for this migration/upgrade.
