VALUES( 'Learn MySQL INSERT Statement', 1) Code language: SQL (Structured Query Language) ( sql ) The following statement inserts a new row into the tasks table: INSERT INTO tasks(title, priority) ) Code language: SQL (Structured Query Language) ( sql ) 1) MySQL INSERT – simple INSERT example Let’s create a new table named tasks for practicing the INSERT statement. In this syntax, rows are separated by commas in the VALUES clause. (vnn,vn2.) Code language: SQL (Structured Query Language) ( sql ) To insert multiple rows into a table using a single INSERT statement, you use the following syntax: INSERT INTO table(c1,c2.) In addition, the positions of columns must be corresponding with the positions of their values. The number of columns and values must be the same. Then, put a comma-separated list of values of the corresponding columns inside the parentheses following the VALUES keyword.First, specify the table name and a list of comma-separated columns inside parentheses after the INSERT INTO clause.The INSERT statement allows you to insert one or more rows into a table. The following illustrates the syntax of the INSERT statement: INSERT INTO table(c1,c2.) Introduction to the MySQL INSERT statement We hope this article helped you with insert or update related queries.Summary: in this tutorial, you will learn how to use the MySQL INSERT statement to insert one or more rows into a table. We already have the row with customer_name = “Rasmus,” Hence, we get an action output message.Īction Output Message : 17:22:35 INSERT INTO customer_data (customer_id, customer_name, customer_place) SELECT * FROM (SELECT 6, “Rasmus”,”TestPlace”) AS tmp_name WHERE NOT EXISTS ( SELECT customer_name FROM customer_data WHERE customer_name = “Rasmus” ) LIMIT 1 0 row(s) affected Records: 0 Duplicates: 0 Warnings: 0 0.00047 sec.Ġ rows affected, so nothing new gets inserted. To have a better understanding of the concept, let us re-run the same query, this time. Since we do not yet have a row with customer_id = 6 the query will insert a new row on running this query. SELECT customer_name FROM customer_data WHERE customer_name = "Rasmus" SELECT * FROM (SELECT 6, "Rasmus","TestPlace") AS tmp_name INSERT INTO customer_data (customer_id, customer_name, customer_place) Example: We want to add one more row to our table customer_data ( refer figure 1.1) or update based on customer_name. In this section, we will be using the NOT EXISTS keyword. MySQL Insert or Update conditional : NOT EXISTS Read more about REPLACE in the official documentation. Also, the action message output said 2 rows affected, which means one got deleted before inserting the other. It shows that customer_name and customer_place got changed in the row with customer_id=2. REPLACE INTO customer_data(customer_id, customer_name, customer_place) VALUES(2, "Hevika","Atlanta") Īction Output Message : 18:27:57 REPLACE INTO customer_data (customer_id, customer_name, customer_place) VALUES(2, “Hevika”,”Atlanta”) 2 row(s) affected 0.0023 secĭoing a select * again on customer_data gives the data as shown in figure 1.5. Observe the below query with an action output message received after running it. We will be using the same example from customer_data table. The difference is: If the new row to be inserted has the same value of the PRIMARY KEY or the UNIQUE index as the existing row, in that case, the old row gets deleted first before inserting the new one.
