Full Name to v Sales Person we can update esql Sales Person. Before we go much further, let’s first wipe out the city column values.

There are three components to an UPDATE statement: Note: The Sales Person ID generated for your table’s rows may be different than what is show in the exercises, since this primary key is auto generated.Keep in mind that when updating data in columns whose data type is CHAR, VARCHAR, or VARBINARY, the padding or truncation of data depends upon the SET ANSI_PADDING setting.When SET ANSI_PADDING OFF then CHAR data types are padded with spaces, VARCHAR data types have trailing spaces removed, and VARBINARY have trailing zeros removed.Update your records on the spreadsheet that you just exported then import it here. For example, if you are matching by Email, it means that it will only update records that do not match the emails in the "Email" selected column of your import. Overwrite “Overwrite” means that the import record will update the matched record with the columns in your import file.In this example, I incorrectly entered names for my companies, so I updated the spreadsheet with the correct names, deleted all columns except for name and Copper ID, and am updating the names by Copper ID: 3. For example, if you are matching by email and choosing overwrite, records that match the email in your import will be overwritten, but only if any data has changed. Click "Continue Import" If you have chosen "Overwrite", you will see the following warning before completing your import.
