You select all columns of all rows from a table with the select * from table_name sql statement. Be careful, this can potentially be a very expensive, poor performance, network intensive type of operation - it is better to select only the columns and rows needed.
It depends on the DBMS MSSQL: SELECT TOP 1 column FROM table MySQL: SELECT column FROM table LIMIT 0,1 (start index, number of rows to get)
116 ÷ 2 = 58 even rows. There will also be 58 odd rows.
1 row of 100 chairs. 2 rows of 50 chairs. 4 rows of 25 chairs. 5 rows of 20 chairs. 10 rows of 10 chairs. 20 rows of 5 chairs. 25 rows of 4 chairs. 50 rows of 2 chairs. 100 rows of 1 chair. Or you could put them all in one big circle.
The Selection Operation is used to select a subset of the tuples (records) from a relation (file) that satisfy a selection condition.If we think of a relation as a table, the select operation select some of the Rows from the table while discarding other Rows. The Projection select certain column from the table and discarding the other columns.The result of the Projection operation can hence be visualized as a vertical partition of the relation into two relations, one has needed columns (attributes) & contain the result of the operations & the other contains in the discarded column.Binamani BoroGuwahati
