Statement.return_generated_keys Example
How to Retrieve Automatically Generated Keys in JDBC? You can retrieve automatically generated keys (also called auto-generated keys or auto increment) from a table using JDBC 3.0 methods getGeneratedKeys. The following are Jave code examples for showing how to use executeQuery of the java.sql.Statement class. You can vote up the examples you like. Your votes will be used in our system to get more good examples. As an example, create the following table in the sample database: CREATE TABLE TestTable (Col1 int IDENTITY, Col2 varchar(50), Col3 int); In the following example, an open connection to the sample database is passed in to the function, an SQL statement is constructed that will add data to the table, and then the statement is run and the IDENTITY column value is displayed. If you include the Statement.RETURNGENERATEDKEYS parameter, the data type of the automatically generated keys in the ResultSet is DECIMAL, regardless of the data type of the corresponding column.

For example, in a table if we have a column with name ID and data type INT, which is auto-incremented and, if we already have 6 records in that table. When you insert the next record using the INSERT statement the ID value of the new record will be 7 and the ID value of its next record will be 8.

あるPRIMARY KEY (USER_ID)
あります(なぜそれがSQL_CREATE

さて、私は?

Jul 09, 2019 The Private Key is generated with your Certificate Signing Request (CSR). The CSR is submitted to the Certificate Authority right after you activate your Certificate. The Private Key must be kept safe and secret on your server or device, because later you’ll need it for Certificate installation.

PreparedStatementはStatementサブインターフェースですので、一部のJDBCドライバーがバグでない限り、これが機能しない理由はありません。
