UPDATE Statements
To modify existing records, use UPDATE statements.
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.
UPDATE <table_name> SET { <column_reference> = <expression> } [ , ... ] WHERE { Id = <expression> } [ { AND | OR } ... ]
<expression> ::=
| @ <parameter>
| ?
| <literal>
You can use the executeUpdate method of the Statement or PreparedStatement classes to execute data manipulation commands and retrieve the rows affected.
String cmd = "UPDATE User SET CN='User Name' WHERE Id = ?";
PreparedStatement pstmt = connection.prepareStatement(cmd);
pstmt.setString(1, "CN=User Name,CN=Users,DC=Domain");
int count = pstmt.executeUpdate();
System.out.println(count + " rows were affected");
connection.close();
