Here is another table prod_back CREATE TABLE hrdb.prod_backup( Multi rows insert by a single INSERT statement INSERT OR REPLACE INTO prod_mast(prod_id, prod_name, prod_rate, prod_qc) The above result shows that, though the prod_id 4 already exists yet it has been modified by INSERT statement, because the INSERT OR REPLACE statement has been used. If we want to modify the row for prod_id is 4, we can use the following statement INSERT OR REPLACE INTO prod_mast(prod_id, prod_name, prod_rate, prod_qc) If we want to insert such a row in which the value of primary key column already exists, then see the result sqlite> INSERT INTO prod_mast(prod_id, prod_name, prod_rate, prod_qc)Įrror: UNIQUE constraint failed: prod_mast.prod_id The empty prod_rate column filled by NULL. SQLite shows empty strings for NULL values by default. nullvalue command tells the SQLite to show NULL values as NULL.

sqlite> SELECT * FROM prod_mast įrom the above result, it seems that the value for the two mentioned columns have been inserted and the value for the prod_qc column have also been inserted because for that column the default value assigned 'OK' at the time of creating the table, but the prod_rate column remains empty. INSERT INTO prod_mast(prod_id, prod_name) Here in the example below, two columns have been specified. In such a cases, values for all columns have to supply. The above example shows that no column list have been specified after the table name. Insert value without mention column list: INSERT INTO prod_mast VALUES(3,'Pakora', 48, 'OK') So it is clear that the SQLite library adds a new id. As the prod_id column is defined as INTEGER PRIMARY KEY, so it is auto-incremented by SQLite. The above example shows that the prod_id column not been included within the column list.

Insert value without PRIMARY KEY column INSERT INTO prod_mast(prod_name, prod_rate, prod_qc) INSERT INTO prod_mast(prod_id, prod_name, prod_rate, prod_qc) We have specified all column names after the table name and all values after the VALUES keyword. The following is the basic INSERT SQL statement. Here we will create a new table prod_mast: CREATE TABLE hrdb.prod_mast( This statement is a part of the SQL Data Manipulation Language, DML. The INSERT works on a single table, and can both insert one row at a time or many rows at once using a SELECT command. The INSERT command is used to create new rows in the specified table.
