SQL INSERT INTO STATEMENT
INSERT INTO STATEMENT
The SQL INSERT statement is used to insert a single record or multiple records into a table.
While inserting a row, if the columns are not specified, it means that vales are added for all of the columns of the table resulting addition of a single row. If it is required to insert values for one or more specific column(s), then it is necessary to specify the name(s) of the column(s) in the SQL query.
The SQL SELECT statement can also be used to insert the rows of one table into another identical table.
While inserting the values, it is needed to enclose the values with single quotes for character or date values.
Syntax:
INSERT INTO < table name > (col1,col2,col3...col n) VALUES (value1,value2,value3…value n);
Parameters:
Name | Description |
---|---|
table_name | Name of the table where data will be inserted. |
col1,col2,col3,con n | Column of the table. |
value1,value2,value3,value n | Values against each column. |
You can use another syntax to insert data. Here, you don't specify column names of the associated table. So, value1 is inserted into the first column of a table, value2 into column2 and so on.
Syntax:
INSERT INTO < table name > VALUES (value1,value2,value3…value n);
Parameters:
Name | Description |
---|---|
table_name | Name of the table where data will be inserted. |
value1,value2,value3,value n | Values against each column. |

Sample table: agents
+------------+----------------------+--------------------+------------+-----------------+---------+ | AGENT_CODE | AGENT_NAME | WORKING_AREA | COMMISSION | PHONE_NO | COUNTRY | +------------+----------------------+--------------------+------------+-----------------+---------+ | A007 | Ramasundar | Bangalore | 0.15 | 077-25814763 | | | A003 | Alex | London | 0.13 | 075-12458969 | | | A008 | Alford | New York | 0.12 | 044-25874365 | | | A011 | Ravi Kumar | Bangalore | 0.15 | 077-45625874 | | | A010 | Santakumar | Chennai | 0.14 | 007-22388644 | | | A012 | Lucida | San Jose | 0.12 | 044-52981425 | | | A005 | Anderson | Brisban | 0.13 | 045-21447739 | | | A001 | Subbarao | Bangalore | 0.14 | 077-12346674 | | | A002 | Mukesh | Mumbai | 0.11 | 029-12358964 | | | A006 | McDen | London | 0.15 | 078-22255588 | | | A004 | Ivan | Torento | 0.15 | 008-22544166 | | | A009 | Benjamin | Hampshair | 0.11 | 008-22536178 | | +------------+----------------------+--------------------+------------+-----------------+---------+
