The number of values in the value list must be the same as the number of columns in the column list.
If you omit the column list, you have to specify values for all columns in the value list. Third, add a comma-separated list of values after the VALUES keyword.
However, it is a good practice to include the column list after the table name. Second, add a comma-separated list of columns after the table name.First, specify the name of the table to which you want to insert data after the INSERT INTO keywords.Let’s examine the INSERT statement in more detail:

SQLite INSERT – inserting a single row into a table In addition, you can insert a row into a table using data provided by a SELECT statement. SQLite provides various forms of the INSERT statements that allow you to insert a single row, multiple rows, and default values into a table. To insert data into a table, you use the INSERT statement.

* JdbcInsert1.Summary: in this tutorial, you will learn how to use SQLite INSERT statement to insert new rows into a table. To help you understand how this process works, the following source code shows a complete Java program that creates a Connection to the database, and then inserts the data as shown previously: You can create your database tables through your database management tools. Note: In this example, I assumed that the database table named Customers is already created. In a real application you’ll just replace the string constants we’ve used with variables that you obtain from (a) an end-user or (b) an input data source. Statement.executeUpdate("INSERT INTO Customers " + "VALUES (1004, 'Cramden', 'Mr.', 'New York', 2001)") Īs you can see, this is pretty easy (once you've seen how it’s done). Statement.executeUpdate("INSERT INTO Customers " + "VALUES (1003, 'Flinstone', 'Mr.', 'Bedrock', 2003)") Statement.executeUpdate("INSERT INTO Customers " + "VALUES (1002, 'McBeal', 'Ms.', 'Boston', 2004)")
We can just re-use the Statement object to insert our new values: Inserting the other three records is just as easy as inserting this record. (Snum stands for Salesperson Number, which we'll use later to link this table to our Salesperson table.) If you're not familiar with SQL, note that you must insert your fields in the order in which your table is defined (Cnum, Lname, Salutation, City, and Snum). (I show the complete process of obtaining a database Connection object below.) Statement.executeUpdate("INSERT INTO Customers " + "VALUES (1001, 'Simpson', 'Mr.', 'Springfield', 2001)") Īs this shows, you (1) create a JDBC Statement object from your Connection instance, and (2) run your SQL INSERT statement using the Statement object's executeUpdate method. Statement statement = conn.createStatement() create a Statement from the connection Here’s an example of how to create a Java Statement object, and then insert a record for a person named Mr. When Sun (now Oracle) created JDBC, they intended to “make the simple things simple.” Step 2: Execute the JDBC INSERT statement If you’re comfortable with SQL, this is a simple process. Execute a SQL INSERT command through the JDBC Statement object.Inserting data into a SQL database table using Java is a simple two-step process: Here’s what the Customers database table looks like: Cnum In all of my examples in this series, I’ll be working with a database named Demo that has a database table named Customers. Step 1: A sample databaseīefore getting into the SQL INSERT statements, you need to know what the sample database table looks like. In this article I’ll take the next step and show how to insert data into a database table using Java, JDBC, and SQL. In my first Java JDBC tutorial (How to connect to a JDBC database) I demonstrated how to connect your Java applications to standard SQL databases like MySQL, SQL Server, Oracle, SQLite, and others using the JDBC Connection object.
