Primary Keys

You can use the getPrimaryKeys method to return information about the primary keys for Zoho Creator tables. You can restrict the results by the table name.

The following code example outputs the column or columns composing the primary key for the [CData].[Employee Management].Leave_Types table:

String connectionString = "jdbc:zohocreator:InitiateOAuth=GETANDREFRESH;";

Connection conn = DriverManager.getConnection(connectionString);
ResultSet rs = conn.getMetaData().getPrimaryKeys("CData","Employee Management","Leave_Types");
while(rs.next()){
  System.out.println(rs.getString("COLUMN_NAME"));
}

The getPrimaryKeys method returns the following columns:


Column Name	Data Type	Description
TABLE_CAT	String	The table catalog
TABLE_SCHEM	String	The table schema.
TABLE_NAME	String	The table name.
COLUMN_NAME	String	The column name.
KEY_SEQ	short	The sequence number, or column index starting from 1, within the foreign key.
