Return Auto Generated Key Queryjdbc Mysql Java
The Microsoft JDBC Driver for SQL Server supports the optional JDBC 3.0 APIs to retrieve automatically generated row identifiers. The main value of this feature is to provide a way to make IDENTITY values available to an application that is updating a database table without a requiring a query and a second round-trip to the server.
Mysql Auto generated Key Value Executes the below program, Which insert the record in the trnemployee table. After record insertion it return the auto generated primary key value getGeneratedKeys method returns the ResultSet object and from that we retrive the primary key number.
- MySQL and Java « Previous Message. 2003 13:57 Subject: Re: retrieving auto-generated keys on bulk insert Allright. I'll buy that. One more caveat though - how much control do you realistically have here? Will there be other applications hitting the database when you are, or is it really only you? Meaning if a statement causes the.
- SQL Server allows only a single IDENTITY column per table. The result set that is returned by getGeneratedKeys method of the SQLServerStatement class will have only one column, with the returned column name of GENERATEDKEYS. If generated keys are requested on a table that has no IDENTITY column, the JDBC driver will return a null result set.
Because SQL Server doesn't support pseudo columns for identifiers, updates that have to use the auto-generated key feature must operate against a table that contains an IDENTITY column. SQL Server allows only a single IDENTITY column per table. The result set that is returned by getGeneratedKeys method of the SQLServerStatement class will have only one column, with the returned column name of GENERATED_KEYS. If generated keys are requested on a table that has no IDENTITY column, the JDBC driver will return a null result set.
As an example, create the following table in the sample database: /cyberghost-premium-key-generator-download.html.
Belkin driver download n300. 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.
