Spring SimpleJdbcCall default (optional) arguments

Question

I am trying to invoke a stored procedure which has default (optional) arguments without passing them and it is not working. Essentially the same problem as described here.

My code:

  SqlParameterSource in = new MapSqlParameterSource()
        .addValue("ownname", "USER")
        .addValue("tabname", cachedTableName)
        .addValue("estimate_percent", 20)
        .addValue("method_opt", "FOR ALL COLUMNS SIZE 1")
        .addValue("degree", 0)
        .addValue("granularity", "AUTO")
        .addValue("cascade", Boolean.TRUE)
        .addValue("no_invalidate", Boolean.FALSE)
        .addValue("force", Boolean.FALSE);

And I get an exception:

Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: Required input parameter 'PARTNAME' is missing
    at org.springframework.jdbc.core.CallableStatementCreatorFactory$CallableStatementCreatorImpl.createCallableStatement(CallableStatementCreatorFactory.java:209)

Where PARTNAME is an optional parameter according to this. Also confirmed by the fact that I can run this procedure w/o the PARTNAME argument manually.

Answer 1

Ater giving up on this question and just passing all the parameters, including optional ones I ran into its inability to pass boolean arguments, because boolean is not an SQL data type, only PL/SQL.

So my current solution is that JDBC is not suited for running stored procedures and this is how I'm working around it:

  jdbcTemplate.execute(
        new CallableStatementCreator() {
           public CallableStatement createCallableStatement(Connection con) throws SQLException{
              CallableStatement cs = con.prepareCall("{call sys.dbms_stats.gather_table_stats(ownname=>user, tabname=>'" + cachedMetadataTableName + "', estimate_percent=>20, method_opt=>'FOR ALL COLUMNS SIZE 1', degree=>0, granularity=>'AUTO', cascade=>TRUE, no_invalidate=>FALSE, force=>FALSE) }");
              return cs;
           }
        },
        new CallableStatementCallback() {
           public Object doInCallableStatement(CallableStatement cs) throws SQLException{
              cs.execute();
              return null; // Whatever is returned here is returned from the jdbcTemplate.execute method
           }
        }
  );
