DELETE Statements

To delete information from a table, use DELETE statements.


The DELETE statement requires the table name in the FROM clause and the row's primary key in the WHERE clause, as shown in the following example:

<delete_statement> ::= DELETE FROM <table_name> 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 number of affected rows, as shown in the following example:
Connection connection = DriverManager.getConnection("jdbc:ibmcloudsqlquery:Api Key=MyAPIKey;",);
String cmd = "DELETE FROM [CloudObjectStorage_1].[SampleBucket_1].Jobs WHERE Id = ?";
PreparedStatement pstmt = connection.prepareStatement(cmd);
pstmt.setString(1, "215776c8-81e1-4f8a-90ad-c70fd395ab41");
int count=pstmt.executeUpdate();
