In Oracle,mysql,sqlserver, the syntax format for the number of rows required to fetch a table

In Oracle, if we ask for the first few rows of the table, use the keyword rownum

Example: SELECT * from student where rownum<=10 results in removing the first 10 rows from the student table

In MySQL, use the keyword limit

Example: SELECT * FROM student limit 10 results in removing the first 10 rows of data

Or select * from student limit to represent two rows of data from the first row, i.e. the second row and the third row of data are taken out

In SQL Server, with the keyword top

Example: SELECT Top * from student results in the first 10 rows of data from the table
