> JDBC {{getPrimaryKeys()}} method returns {{_KEY}} as column name rather than actual column name. This breaks apps that expect a valid column name as the primary key.
> Trivially reproducible:
> {noformat}
>   public static void main(String[] args) throws Exception {
>     // Register JDBC driver.
>     Class.forName("org.apache.ignite.IgniteJdbcThinDriver");
>     // Open JDBC connection.
>     try (Connection conn = DriverManager.getConnection("jdbc:ignite:thin://127.0.0.1/")) {
>       // Create database tables.
>       try (Statement stmt = conn.createStatement()) {
>         stmt.executeUpdate("CREATE TABLE TESTER (" + " ID LONG PRIMARY KEY, NAME VARCHAR) " + " WITH \"template=replicated\"");
>       }
>       // Get database metadata
>       DatabaseMetaData md = conn.getMetaData();
>       // Get primary keys
>       ResultSet rs = md.getPrimaryKeys(conn.getCatalog(), "", "TESTER");
>       //
>       while (rs.next()) {
>         // Column 4 is COLUMN_NAME
>         System.out.println("Primary key column is " + rs.getString(4));
>       }
>     }
>   }
> {noformat}
> Expected output is:
> {noformat}
> Primary key column is ID
> {noformat}
> Actual output is:
> {noformat}
> Primary key column is _KEY
> {noformat}
