To modify existing records, use UPDATE statements.

Limitations

Updates are only supported in Trino releases 352 or later.

Update Syntax

The UPDATE statement takes as input a comma-separated list of columns and new column values as name-value pairs in the SET clause, as shown in the following example:

UPDATE <table_name> SET <select_statement> | {<column_reference> = <expression> [ , ... ]} WHERE { Id = <expression>  } [ { AND | OR } ... ] 

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

The following is an example query:

UPDATE [Hive].[Default].Customers SET Name='Floppy Disks' WHERE Id = @myId
