View Oracle running status by using SQLPlus: Query the V$INSTANCE table; through the Overview tab of Oracle Enterprise Manager; through the Monitoring dashboard of Oracle Cloud Control; through the Summary section of Oracle Grid Control.

Oracle sequences are used to generate unique sequences of numbers, usually used as primary keys or identifiers. Creating a sequence requires specifying the sequence name, starting value, incremental value, maximum value, minimum value, cache size, and loop flags. When using a sequence, use the NEXTVAL keyword to get the next value of the sequence.

Oracle provides multiple deduplication query methods: The DISTINCT keyword returns a unique value for each column. The GROUP BY clause groups the results and returns a non-repetitive value for each group. The UNIQUE keyword is used to create an index containing only unique rows, and querying the index will automatically deduplicate. The ROW_NUMBER() function assigns unique numbers and filters out results that contain only line 1. The MIN() or MAX() function returns non-repetitive values of a numeric column. The INTERSECT operator returns the common values of the two result sets (no duplicates).

Use the ALTER TABLE statement, the specific syntax is as follows: ALTER TABLE table_name ADD column_name data_type [constraint-clause]. Where: table_name is the table name, column_name is the field name, data_type is the data type, and constraint-clause is an optional constraint. Example: ALTER TABLE employees ADD email VARCHAR2(100) Add an email field to the employees table.

Oracle cursor is a database pointer used to traverse a record set, and its features include record-by-record processing, efficiency, updating, and security. Use scenarios include batch processing of data, updating or deleting specific records and transactions.

To delete a primary key in Oracle, you need to follow the following steps: 1. Delete the referenced foreign key constraint; 2. Delete the primary key constraint; 3. If necessary, add a new primary key constraint.

The steps to modify the field name in an Oracle table are as follows: Connect to the database. Use the ALTER TABLE statement to modify the field name. Specify the table name and the old field name. Specify the new field name. Submit changes.

Oracle Environment Variable Configuration Guide: Create an ORACLE_HOME environment variable, pointing to the Oracle home directory. Add the Oracle binary directory to the PATH environment variable. Set the TNS_ADMIN environment variable (if the file is named using TNS). Verify the environment variable settings to make sure the output displays the set variables.
