Learn about using INSERT INTO SQL statements. The INSERT INTO statement is used to insert or add new data rows in a table. There are two methods to INSERT the data rows in a table. In First method, column names are not specified and the values are given in a bracket separated by a comma.
In this method the values for each column must be specified and the values should be provided sequentially by columns. "INSERT INTO tablename VALUES (value1, value2, value3);" In second method, the column names are given in first bracket and the values are given in another bracket. In this method we can INSERT values to only selected column names.
This is the convenient way to store the data rows, as we can see which value is going to be stored in which column. "INSERT INTO tablename (column1, column2, column3) VALUES (value1, value2, value3);" While using INSERT INTO statement the string values must be wrapped in single quotes, while wrapping numeric values in quotes is optional or not required.
I'll select the "school" database, "USE school;" I'll run a simple SQL statement to display all the data rows in teachers table using SQL statement, "SELECT * FROM teachers;" Add new data row using SQL statement, "INSERT INTO teachers VALUES (NULL, 'Peter Brown', 1234509876);" In this INSERT INTO SQL statement, column names are not specified. Since, the teacherid column is auto increment that is it will automatically add the next number for the data row, we provided the 'NULL' value means no value for that column. Press enter to execute the SQL statement.
If you see the message, "Query OK, 1 row affected", it means the data row was successfully inserted to the table.
