Question

I’ve written the following Spring JDBC API StoredProcedure sub-class:

class GetLdapPropertiesStoredProcedure extends StoredProcedure {  protected GetLdapPropertiesStoredProcedure(JdbcTemplate jdbcTemplate) {     super(jdbcTemplate, 'get_ldap_properties');     setFunction(true);     declareParameter(new SqlReturnResultSet('rs', new ProductPropertiesMapper()));     declareParameter(new SqlParameter('in_ldap_code', Types.VARCHAR));     compile(); }  public Properties execute(String productCode) {     HashMap input = new HashMap();     input.put('in_ldap_code', productCode);      Map results = execute(input);      Collection<Map.Entry<Object,Object>> entries = (Collection<Map.Entry<Object,Object>>) results.get('rs');     Properties properties = new Properties();     properties.entrySet().addAll(entries);     return properties; }  } 

Which calls the following Oracle function:

FUNCTION get_ldap_properties ( in_ldap_code   IN VARCHAR2 ) RETURN rowset; 

However, when I call the above I get the following Oracle exception:

java.sql.SQLException: ORA-06550: line 1, column 13: PLS-00306: wrong number or types of arguments in call to 'GET_LDAP_PROPERTIES' ORA-06550: line 1, column 7: PL/SQL: Statement ignored 

Can anyone please see what I’m doing wrong?

Answer 1

This is the statement you’ll get for a function call (i.e. with setFunction(true)) :

{ ? = call get_ldap_properties(?) } 

So you need to add a first out parameter for the return value. Try this instead:

setFunction(true);  // The return value parameter must be the first parameter that you declare. declareParameter(new SqlOutParameter('RETURN_VALUE', OracleTypes.CURSOR, new ProductPropertiesMapper())); 

Edit: Fixed the syntax to deal with the function's return value and the rowset when using Oracle according to Thomas Risberg's answer on Spring Community Forums.
