How to use limit in oracle

LIMIT Clause in Oracle
What is LIMIT clause?
The LIMIT clause is used to limit the number of rows retrieved from an Oracle database table.
Syntax:
<code>SELECT * FROM table_name LIMIT start_row, row_count</code>
Where:
-
start_row
Specifies the number of rows to skip, starting from 0 . -
row_count
Specifies the number of rows to retrieve.
Usage:
The LIMIT clause is placed at the end of the SELECT statement. It can be used to page results or retrieve a specific number of rows.
Example:
Retrieve the first 10 rows:
<code>SELECT * FROM customers LIMIT 10;</code>
Retrieve the 5 rows starting from row 10 :
<code>SELECT * FROM customers LIMIT 9, 5;</code>
Note:
- If
start_row
is not specified, the default value is 0, starting from the first row start. - If
row_count
is negative, no rows will be retrieved. - The LIMIT clause, when used in conjunction with the ORDER BY clause, controls the order in which rows are retrieved.
- In some cases, the LIMIT clause may affect query performance.

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The function in Oracle to calculate the number of days between two dates is DATEDIFF(). The specific usage is as follows: Specify the time interval unit: interval (such as day, month, year) Specify two date values: date1 and date2DATEDIFF(interval, date1, date2) Return the difference in days

The Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

The INTERVAL data type in Oracle is used to represent time intervals. The syntax is INTERVAL <precision> <unit>. You can use addition, subtraction, multiplication and division operations to operate INTERVAL, which is suitable for scenarios such as storing time data and calculating date differences.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

Oracle database server hardware configuration requirements: Processor: multi-core, with a main frequency of at least 2.5 GHz. For large databases, 32 cores or more are recommended. Memory: At least 8GB for small databases, 16-64GB for medium sizes, up to 512GB or more for large databases or heavy workloads. Storage: SSD or NVMe disks, RAID arrays for redundancy and performance. Network: High-speed network (10GbE or higher), dedicated network card, low-latency network. Others: Stable power supply, redundant components, compatible operating system and software, heat dissipation and cooling system.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.

The method of replacing strings in Oracle is to use the REPLACE function. The syntax of this function is: REPLACE(string, search_string, replace_string). Usage steps: 1. Identify the substring to be replaced; 2. Determine the new string to replace the substring; 3. Use the REPLACE function to replace. Advanced usage includes: multiple replacements, case sensitivity, special character replacement, etc.
