We are calling the pl/sql stored procedure through Spring SimpleJdbcCall, the fetchsize set on the JdbcTemplate is being ignored by SimpleJdbcCall. The rowmapper resultset fetch size is set to 10 even though we have set the jdbctemplate fetchsize to 200. Any idea why this happens and how to fix it?
Have printed the fetchsize of resultset in the rowmapper in the below code snippet - Once it is 200 and other time it is 10 even though I use the same JdbcTemplate on both occassion.
This direct execution through jdbctemplate returns fetchsize of 200 in the row mapper
jdbcTemplate = new JdbcTemplate(ds);
jdbcTemplate.setResultsMapCaseInsensitive(true);
jdbcTemplate.setFetchSize(200);
List temp = jdbcTemplate.query("select 1 from dual", new ParameterizedRowMapper() {
public Object mapRow(ResultSet resultSet, int i) throws SQLException {
System.out.println("Direct template : " + resultSet.getFetchSize());
return new String(resultSet.getString(1));
}
});
This execution through SimpleJdbcCall is always returning fetchsize of 10 in the rowmapper
jdbcCall = new SimpleJdbcCall(jdbcTemplate).withSchemaName(schemaName)
.withCatalogName(catalogName).withProcedureName(functionName);
jdbcCall.returningResultSet((String) outItValues.next(), new ParameterizedRowMapper<Map<String, Object>>() {
public Map<String, Object> mapRow(ResultSet rs, int row) throws SQLException {
System.out.println("Through simplejdbccall " + rs.getFetchSize());
return extractRS(rs, row);
}
});
outputList = (List<Map<String, Object>>) jdbcCall.executeObject(List.class, inParam);
