The following commands select data from the customers table and export it to the data.csv file. Issue the query to select data from the table to which you want to export.Set the output mode to CSV to instruct the sqlite3 tool to issue the result in the CSV mode.Turn on the header of the result set using the.To export data from the SQLite database to a CSV file, you use these steps: By using the sqlite3 tool, you can use the SQL statements and dot-commands to interact with the SQLite database. SQLite project provides you with a command-line program called sqlite3 or sqlite3.exe on Windows. Export SQLite Database to a CSV file using sqlite3 tool There are several ways to dump data from an SQLite database to a CSV file. Here is the result after insert.Summary: in this tutorial, you will learn how to export SQLite database to a CSV file. INSERT INTO prod_backup SELECT * FROM prod_mast Here is the statement to insert all rows of prod_mast table rows into pord_backup table. 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. ![]()
