You need to add the follow line: AUTHID CURRENTUSER. CREATE OR REPLACE PROCEDURE spupdateacounts( accountsfiledir IN VARCHAR2, accountsfilename IN VARCHAR2) AUTHID CURRENTUSER IS BEGIN EXECUTE IMMEDIATE ’CREATE OR REPLACE DIRECTORY extaccountsdir AS ’ accountsfiledir ’; EXECUTE IMMEDIATE ’grant read, write on directory extaccountsdir to myuser’; EXECUTE IMMEDIATE ’drop. The procedure with execute immediate command is failing with ORA-01031: insufficient privileges. The procedure is trying to create a table and drop the table. The owner of the procedure has DBA role. Still the user cannot create the table or drop the table through execute immediate command. You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn’t reference the table by the schema name.
Learn the cause and how to resolve the ORA-00942 error message in Oracle.Description
When you encounter an ORA-00942 error, the following error message will appear:
*ORA-00942: table or view does not existCause
You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn’t reference the table by the schema name.Resolution
The option(s) to resolve this Oracle error are:Option #1
If this error occurred because the table or view does not exist, you will need to create the table or view.
You can check to see if the table exists in Oracle by executing the following SQL statement:
For example, if you are looking for a suppliers table, you would execute:Option #2
If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object.Option #3
If this error occurred because the table/view belongs to another schema and you didn’t reference the table by the schema name, you will need to rewrite your SQL to include the schema name.
For example, you may have executed the following SQL statement:
But the suppliers table is not owned by you, but rather, it is owned by a schema called app, you could fix your SQL as follows:
If you do not know what schema the suppliers table/view belongs to, you can execute the following SQL to find out:
This will return the schema name who owns the suppliers table.
Summary: in this tutorial, you will learn how to use the Oracle DROP TABLE statement to remove an existing table.Introduction to Oracle DROP TABLE statement
To move a table to the recycle bin or remove it entirely from the database, you use the DROP TABLE statement:
In this statement:
*First, indicate the table and its schema that you want to drop after the DROP TABLE clause. If you don’t specify the schema name explicitly, the statement assumes that you are removing the table from your own schema.
*Second, specify CASCADE CONSTRAINTS clause to remove all referential integrity constraints which refer to primary and unique keys in the table. In case such referential integrity constraints exist and you don’t use this clause, Oracle returns an error and stops removing the table.
*Third, specify PURGE clause if you want to drop the table and release the space associated with it at once. By using the PURGE clause, Oracle will not place the table and its dependent objects into the recycle bin.
Notice that the PURGE clause does not allow you to roll back or recover the table that you dropped. Therefore, it is useful if you don’t want the sensitive data to appear in the recycle bin.Execute Immediate Drop Table Error DefinitionOracle DROP TABLE examples
Let’s look at some examples of using the DROP TABLE statement.Basic Oracle DROP TABLE example
The following CREATE TABLE statement creates persons table for the demonstration:
The following example drops the persons table from the database:Oracle DROP TABLE CASCADE CONSTRAINTS example
The following statements create two new tables named brands and cars:
In these tables, each brand has 1 or more cars while each car belongs to only one brand.
The following statement tries to drop the brands table:
Oracle issued the following error:
This is because the primary key of the brands table is currently referenced by the brand_id column in the cars table.
The following statement returns all foreign key constraints of the cars table:
To drop the brands table, you must use the CASCADE CONSTRAINTS clause as follows:
This statement dropped not only the brands table but also the foreign key constraint fk_brand from the cars Mac citrix download. table.
If you execute again the statement to get the foreign key constraints in the cars table, you will not see any row returned.Oracle DROP TABLE PURGE exampleExecute Immediate Drop Table Error Example
The following statement drops the cars table using the PURGE clause:Drop multiple tables at onceOracle Execute Immediate Into
Oracle provides no direct way to drop multiple tables at once. However, you can use the following PL/SQL block to do it:
This block deletes all tables whose names start with TEST_.
To test this code, you can first create three tables: test_1, test_2 and test_3 as follows:
Then, execute the PL/SQL block above.
In this tutorial, you have learned how to use the Oracle DROP TABLE statement to drop a table from the database.
