![]() No other records would be returned by this query. It doesnt matter if the actual data in the key columns would be shorter than the maximum declared sizes. On a memory-optimized table, a nonclustered index cant have key columns whose maximum declared sizes exceed 2,500 bytes. Now the results would be sorted by contact_id in ascending order, so the first 5 smallest contact_id records that have a website of '' would be returned by this SELECT LIMIT statement. No limit for a hash index, as long as all index keys fit in-row. If we wanted to select the 5 smallest contact_id values instead of the largest, we could change the sort order as follows: SELECT contact_id, last_name, first_name If there are other records in the contacts table that have a website value of '', they will not be returned by the SELECT LIMIT statement in SQL. Note that the results are sorted by contact_id in descending order so this means that the 5 largest contact_id values will be returned by the SELECT LIMIT statement. So the above is the MySQL code to select all columns of the table named tablename and limit the amount of rows returned to 5 rows. This SQL SELECT LIMIT example would select the first 5 records from the contacts table where the website is ''. Let's look at how to use a SELECT statement with a LIMIT clause in SQL.įor example: SELECT contact_id, last_name, first_name The first row returned by LIMIT will be determined by offset_value. This is where sort order matters so be sure to use an ORDER BY clause appropriately. For example, LIMIT 10 would return the first 10 rows matching the SELECT criteria. How to SELECT the last 10 rows of an SQL table which has no ID field Ask Question. LIMIT number_rows It specifies a limited number of rows in the result set to be returned based on number_rows. ASC is ascending order and DESC is descending order. ![]() It is used in the SELECT LIMIT statement so that you can order the results and target those records that you wish to return. ![]() The conditions that must be met for the records to be selected. There must be at least one table listed in the FROM clause. ![]() tables The tables that you wish to retrieve records from. LIMIT number_rows Parameters or Arguments expressions The columns or calculations that you wish to retrieve. The syntax for the SELECT LIMIT statement in SQL is: SELECT expressions ![]()
