Video Tutorial 6 SQL. INSERT INTO/ INSERT INTO SELECT with MySql WorkbenchThe SQL INSERT INTO StatementThe INSERT INTO statement is used to insert new records in a table. Show
SQL INSERT INTO SyntaxTo add a new record, you must specify which table the record should go into, which fields you assign values to, and finally the values to be assigned. It is possible to write the INSERT INTO statement in two forms. The first form does not specify the column names where the data will be inserted, only their values: INSERT INTO table_name VALUES (value1,value2,value3,...); The second form specifies both the column names and the values to be inserted: INSERT INTO table_name (column1,column2,column3,...) VALUES (value1,value2,value3,...); SQL INSERT INTO EXAMPLEIn a new table "publisher2" we insert two new values; INSERT INTO eli.publisher2 (name, phone) VALUES ('New Store', '555 666'); Below we can see the data in our table after the query SQL INSERT INTO; With SQL, you can copy information from one table into another. The SQL INSERT INTO SELECT StatementThe INSERT INTO SELECT statement selects data from one table and inserts it into an existing table. Any existing rows in the target table are unaffected. SQL INSERT INTO SELECT SyntaxWe can copy all columns from one table to another, existing table: INSERT INTO table2 SELECT * FROM table1; Or we can copy only the columns we want to into another, existing table: INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1; SQL INSERT INTO SELECT ExampleWe are going to copy values from the columns "name" and "phone" from the table "publisher" into the table "publisher2"; INSERT INTO eli.publisher2 (name, phone) SELECT name, phone from eli.publisher; Below we can see the data in our table after the query INSERT INTO SELECT; Notice that in both the cases of INSERT INTO or INSERT INTO SELECT you don´t have to write the columns if the values match the type and size of the columns we are inserting them into; INSERT INTO eli.publisher2 VALUES (4, 'Old store', '555 999'); The article covers the basic syntax of the MySQL INSERT statements and explains how to use the INSERT command in the MySQL table using dbForge Studio for MySQL. Introduction to a MySQL INSERT StatementThe INSERT statement is used to add data to a table. The INSERT INTO command inserts one or multiple rows into a MySQL table. Depending on the number of rows you want to add, the syntax slightly differs. MySQL INSERT INTO – General SyntaxWhen inserting a single row into the MySQL table, the syntax is as follows:
In the INSERT INTO query, you should specify the following information:
The number of columns and values should match; otherwise, it fails. When inserting multiple rows into a MySQL table, the syntax is as follows:
Here you should enter the following information:
In addition, rows are separated by commas in the VALUES clause. MySQL INSERT ExamplesLet’s explore some examples of using a MySQL INSERT statement when performing data-related tasks. To start with, create three tables: Customers, Products01, and Smartphones by executing the following script:
MySQL INSERT command used to insert specified valuesThis command can be used when it is necessary to add values and columns for the specified rows. For example, add data only for the FirstName and LastName columns of the Customers table.
The command inserts values in the FirstName and LastName columns of the Customers MySQL table. Since the Age column uses Null as a default value, MySQL inserts Null into the Age column if you do not specify explicitly its value in the INSERT statement. MySQL INSERT command used to insert values to all columnsThis command can be used in order to add values to all columns. For example, add values to the Product01 table. Keep in mind that the order of values should match the order of columns in the table.
The statement inserts the specified values into all columns of the Product01 table. MySQL INSERT command used to insert the default valueThis command can be used when the default value is specified for the column. For example, the default value for the ProductCount column of the Products01 table equals 0. To insert the default value, execute either of the following queries:
The statement inserts the default value for the ProductCount column. MySQL INSERT used to insert a specific valueTo insert values into the columns, we can use the SET clause instead of the VALUES clause.
In the output, the statement inserts values into the columns based on the explicitly specified values in the SET clause. MySQL INSERT used to insert data from another tableUsing the SELECT clause in the MySQL INSERT INTO statement allows inserting the rows generated by the SELECT statement into the target MySQL table.
In this case, the INSERT INTO statement copies the rows you retrieved with the SELECT statement from the Smartphones table and inserts them into the Products01 table. If you want to retrieve specific rows based on the condition, apply filtering options in the WHERE clause. Keep in mind that the structure of both tables should match; otherwise, it won’t work.
This command adds to the Products01 table values from the Smartphones table where the price equals 34000. You can also copy and insert specified columns from another table. However, in this case, make sure that there is no record with the specified name in the target table; otherwise, it fails, and the error occurs. MySQL INSERT – ignore errors when inserting dataIn case you face errors or any unexpected behavior while executing the insertion of rows into the MySQL table, the statement execution is interrupted. Rows with valid and invalid values are not added to the table. For example, execute the following query:
This statement returns the error because the record with this ID already exists. Now, modify the statement with IGNORE. It allows you to insert rows with valid values but overpass the rows with invalid values.
As a result, the script was executed without errors. MySQL will notify you that rows were added to the table. Creating the INSERT INTO Query with dbForge Studio for MySQLAll the data manipulations, including the Create, Select, Insert, Update, Delete, or Drop operations can be easily performed with dbForge Studio for MySQL. The tool offers a rich set of advanced capabilities and features to boost your productivity and save your time when developing, managing, and deploying MySQL database in the easy-to-use interface. Assume we need to add a new customer to the database. In dbForge Studio for MySQL, we can use the Generate Script As feature to insert one or multiple rows in the MySQL table. To insert information about customers, do the following: 1. In Database Explorer, right-click the required table and select Generate Script As > INSERT > To New SQL Window. The SQL code editor opens containing the automatically generated script. 2. In the SQL code editor, insert data for the specified columns (first_name, last_name, and email) into the VALUES clause. 3. On the standard toolbar, click Execute.The statement adds the First Name, Last Name, and email of the new customer to the bottom line of the grid.
