Annotation Type PrepareKey

@Retention(value=SOURCE)
@Target(value=LOCAL_VARIABLE)
public @interface PrepareKey

Annotation for local variables marking PreparedStatement to be generated. SQL query is taken from preceding javadoc comments.

Example:

 String messageText = ...;
 /**
  * INSERT INTO LOG (MESSAGE) VALUES (:messageText)
  */
 @PrepareKey("id") PreparedStatement stmt = null;
 executeUpdate(stmt);
 int id = getGeneratedKeys()[0].intValue();
 

Preprocessor generates code required to prepare statement with given auto-generated columns and set its parameters.

Note that parameters referenced in query (as :paramName) should be accessible as variables in the current scope.

You can use string and query substitution in comments, see Query.

Optional Element Summary

value Comma-separated list of column names which are auto-generated by the statement.

value

Comma-separated list of column names which are auto-generated by the statement. Leave default value to return all generated keys (but the order is unspecified, plus such feature may be not supported).

Generated key values can be retrieved by GBase.getGeneratedKeys(java.sql.PreparedStatement) method, which returns array of generated key values - one value for each given column (order of columns is preserved if the value was specified).

Default:
