> ---------------------------------------------------------
>
> Key: IGNITE-9606
> URL: https://issues.apache.org/jira/browse/IGNITE-9606
> Project: Ignite
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.6
> Reporter: Pat Patterson
> Assignee: Pavel Kuznetsov
> Priority: Major
>
> 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}
