SQLite – INSERT Query
SQLite INSERT INTO Statement is used to add new rows of data into a table in the database.
Syntax
Following are the two basic syntaxes of INSERT INTO statement.
INSERT INTO TABLE_NAME [(column1, column2, column3,...columnN)] VALUES (value1, value2, value3,...valueN);
Here, column1, column2,…columnN are the names of the columns in the table into which you want to insert data.
You may not need to specify the column(s) name in the SQLite query if you are adding values for all the columns of the table. However, make sure the order of the values is in the same order as the columns in the table. The SQLite INSERT INTO syntax would be as follows −
INSERT INTO TABLE_NAME VALUES (value1,value2,value3,...valueN);
Example
Consider you already have created COMPANY table in your testDB.db as follows −
sqlite> CREATE TABLE COMPANY( ID INT PRIMARY KEY NOT NULL, NAME TEXT NOT NULL, AGE INT NOT NULL, ADDRESS CHAR(50), SALARY REAL );
Now, the following statements would create six records in COMPANY table.
INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (1, ''Paul'', 32, ''California'', 20000.00 ); INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (2, ''Allen'', 25, ''Texas'', 15000.00 ); INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (3, ''Teddy'', 23, ''Norway'', 20000.00 ); INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (4, ''Mark'', 25, ''Rich-Mond '', 65000.00 ); INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (5, ''David'', 27, ''Texas'', 85000.00 ); INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) VALUES (6, ''Kim'', 22, ''South-Hall'', 45000.00 );
You can create a record in COMPANY table using the second syntax as follows −
INSERT INTO COMPANY VALUES (7, ''James'', 24, ''Houston'', 10000.00 );
All the above statements would create the following records in COMPANY table. In the next chapter, you will learn how to display all these records from a table.
ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 1 Paul 32 California 20000.0 2 Allen 25 Texas 15000.0 3 Teddy 23 Norway 20000.0 4 Mark 25 Rich-Mond 65000.0 5 David 27 Texas 85000.0 6 Kim 22 South-Hall 45000.0 7 James 24 Houston 10000.0
Populate One Table Using Another Table
You can populate data into a table through select statement over another table provided another table has a set of fields, which are required to populate the first table. Here is the syntax −
INSERT INTO first_table_name [(column1, column2, ... columnN)] SELECT column1, column2, ...columnN FROM second_table_name [WHERE condition];
For now, you can skip the above statement. First, let”s learn SELECT and WHERE clauses which will be covered in subsequent chapters.
