Limit Columns Certificate For Free

To get the last 10 rows in SQL, you can use the ORDER BY clause with the DESC (descending) or ASC (ascending) keyword to sort the rows, and then use the LIMIT clause to limit the result set to the last 10 rows.

The following is the syntax to get the last 10 records from the table. Here, we have used LIMIT clause. SELECT * FROM ( SELECT * FROM yourTableName ORDER BY id DESC LIMIT 10 )Var1 ORDER BY id ASC; Let us now implement the above query.

SELECT * FROM MYTABLE WHERE INSTR(ColumnName,' ') > 0; Essentially in this query it finds the character position containing first space from the column values and when it finds the first space in it the index value should be greater than 1 and it should display all the records based on that.

The TOP clause is used to fetch the n no of top records from the table. The LIMIT is used to retreive the records from one or more tables from the database. And we can limit the no of records returned from the database. Most of the SQL databases are not support the LIMIT command.
