I have a MySQL table like this
id Name count
1 ABC 1
2 CDF 3
3 FGH 4
using simply select query I get the values as
1 ABC 1
2 CDF 3
3 FGH 4
How I can get the result like this
1 ABC 1
2 CDF 3
3 FGH 4
4 NULL 0
You can see Last row. When Records are finished an extra row in this format
last_id+1, Null ,0 should be added. You can see above. Even I have no such row in my original table. There may be N rows not fixed 3,4
216
To insert a row into a table, you need to specify three things: First, the table, which you want to insert a new row, in the INSERT INTO clause. Second, a comma-separated list of columns in the table surrounded by parentheses. Third, a comma-separated list of values surrounded by parentheses in the VALUES clause.
You need to use ORDER BY clause to get the second last row of a table in MySQL. The syntax is as follows. select *from yourTableName order by yourColumnName DESC LIMIT 1,1; To understand the above syntax, let us create a table.
Here is the basic syntax for adding rows to a table in SQL: INSERT INTO table_name (column1, column2, column3,etc) VALUES (value1, value2, value3, etc); The first line of code uses the INSERT statement followed by the name of the table you want to add the data to.
First, specify the name of table that you want to insert after the INSERT INTO keywords. Second, specify a comma-separated column list inside parentheses after the table name. Third, specify a comma-separated list of row data in the VALUES clause. Each element of the list represents a row.
The answer is very simple
select (select max(id) from mytable)+1 as id, NULL as Name, 0 as count union all select id,Name,count from mytable;
