Based on your description, your query is not correct; you should rewrite it, likely using parenthesis to define your actually desired value expression.

This may or may not be what you intended:

SELECT company_code, item_code, item_description, product_line, udf_item_width, udf_item_length, sales_unit_measure, ''as mat_type
FROM mas_combined_item_master
WHERE (company_code='BUR' OR company_code='SNJ' OR company_code='EBC')
AND udf_edb_managed=''
AND item_code LIKE 'S-%'
ORDER BY item_code;
