How delete all rows from table in SQL?

To remove one or more rows in a table:
  1. First, you specify the table name where you want to remove data in the DELETE FROM clause.
  2. Second, you put a condition in the WHERE clause to specify which rows to remove. If you omit the WHERE clause, the statement will remove all rows in the table.

Similarly, how do you delete all rows in a table?

To delete every row in a table:

  1. Use the DELETE statement without specifying a WHERE clause. With segmented table spaces, deleting all rows of a table is very fast.
  2. Use the TRUNCATE statement. The TRUNCATE statement can provide the following advantages over a DELETE statement:
  3. Use the DROP TABLE statement.

Likewise, how do you delete a complete table in SQL? To delete an entire table including all of its rows, issue the drop table command followed by the tablename. drop table is different from deleting all of the records in the table. Deleting all of the records in the table leaves the table including column and constraint information.

Also to know, how do you delete a row in a table?

To do this, select the row or column and then press the Delete key.

  1. Right-click in a table cell, row, or column you want to delete.
  2. On the menu, click Delete Cells.
  3. To delete one cell, choose Shift cells left or Shift cells up. To delete the row, click Delete entire row. To delete the column, click Delete entire column.

What would keep the delete statement without the where clause from deleting all the rows in a table?

TRUNCATE. TRUNCATE is a statement that will essentially remove all records from the table, just as if you had used DELETE without a WHERE clause. This means TRUNCATE will remove all records in your table, but its structure will remain intact.
