Lets look at an example showing how to use the SQL UPDATE statement to update a single column in a table. In this UPDATE example, we have a table called customers with the following data customeridlastnamefirstnamefavoritewebsite. Jackson. Joetechonthenet. Smith. Janedigminecraft. Ferguson. Samanthabigactivities. Reynolds. Allencheckyourmath. Anderson. Paige. NULL9. Johnson. Derektechonthenet.

In this UPDATE example, the firstname field is set to Judy in the customers table where the customerid is equal to 8. Example Update multiple columns. Lets look at an UPDATE example that shows how to update more than one column in a table. TIP When you update multiple columns in an UPDATE statement, you need to comma separate the columnvalue pairs in the SET clause. In this UPDATE example, we have a table called suppliers with the following data supplieridsuppliernamecitystate. Microsoft. Redmond. Washington. 20. 0Google. Mountain View. California. Oracle. Redwood City. California. 40. 0Kimberly Clark. Irving. Texas. 50. Tyson Foods. Springdale. Arkansas. 60. 0SC Johnson. Racine. Wisconsin. Dole Food Company. Westlake Village.

Enter the following UPDATE statement Try It. UPDATE suppliers. SET supplierid 1. Apple. city Cupertino. WHERE suppliername Google There will be 1 record updated. Select the data from the suppliers table again SELECT FROM suppliers These are the results that you should see supplieridsuppliernamecitystate. Microsoft. Redmond. Command And Conquer Renegade Game. Washington. 15. 0Apple. Cupertino. California. Oracle. Redwood City. California. 40. 0Kimberly Clark. Irving. Texas. 50. Tyson Foods. Springdale. Arkansas. 60. 0SC Johnson. Racine. Wisconsin. Dole Food Company. Westlake Village. California. 80. 0Flowers Foods. Thomasville. Georgia. Electronic Arts. Redwood City. California. This UPDATE example would update the supplierid to 1. Apple and city to Cupertino where the suppliername is Google. Example Update table with data from another table. Lets look at an UPDATE example that shows how to update a table with data from another table. In this UPDATE example, we have a table called products with the following data productidproductnamecategoryid. Pear. 50. 2Banana. Orange. 50. 4Apple. Bread. 75. 6Sliced Ham. Kleenex. NULLAnd a table called summarydata with the following data productidcurrentcategory. Now lets update the summarydata table with values from the products table. Enter the following UPDATE statement UPDATE summarydata. SET currentcategory SELECT categoryid. FROM products. WHERE products. WHERE EXISTS SELECT categoryid. FROM products. WHERE products. There will be 5 records update. Select the data from the summarydata table again SELECT FROM summarydata These are the results that you should see productidcurrentcategory. This example would update the currentcategory field in the summarydata table with the categoryid from the products table where the productid values match. The first 5 records in the summarydata table have been updated. TIP Notice that our UPDATE statement included an EXISTS condition in the WHERE clause to make sure that there was a matching productid in both the products and summarydata table before updating the record. If we hadnt included the EXISTS condition, the UPDATE query would have updated the currentcategory field to NULL in the 6th row of the summarydata table because the products table does not have a record where productid8.
