This will result in more than 10% of the full record set being returned. So if the last position in the SELECT TOP(10) PERCENT record set is a tie, then these tied records would be returned by the SELECT TOP statement. The WITH TIES clause would include rows that may be tied in last place within the limited result set. You could modify this example to include the WITH TIES clause as follows: SELECT TOP(10) PERCENT WITH TIES The other 90% of the result set would not be returned by the SELECT statement.
So in this example, the SELECT statement would return the top 10% of records from the employees table where the last_name is 'Anderson'. This SQL Server SELECT TOP example would select the first 10% of the records from the full result set. Let's look at a SQL Server example, where we use the TOP PERCENT keyword in the SELECT statement. ASC is ascending order and DESC is descending order. It is used in the SELECT TOP 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. expressions The columns or calculations that you wish to retrieve. This may result in more rows be returned than the TOP parameter permits. toad for sql server freeware,Filter by All Products Oracle SQL Server IBM DB2 MySQL NoSQL Postgres SAP. If the WITH TIES clause is specified, then rows tied in last place within the limited result set are returned. For example, TOP(10) PERCENT would return the top 10% of the full result set. First off, if you run a web server, you can use phpMyAdmin, which is nice because it will work on any platform that has a web browser.
If PERCENT is specified, then the top rows are based on a percentage of the total result set (as specfied by the top_value). There are numerous Mac OS clients for MySQL, all of which work for MariaDB, although you generally have to use SQL statements to use MariaDB features like virtual columns, etc. For example, TOP(10) would return the top 10 rows from the full result set. ] Parameters or Arguments TOP (top_value) Returns the top number of rows in the result set based on top_value.
