CREATE TABLE table_204_229 (id NUMBER, "property" CLOB, "test method" CLOB, "units" CLOB, "4275" CLOB, "4301" CLOB, "4435" CLOB, "4630" CLOB, "4645" CLOB)

what property comes before tensile elongation ?
SELECT "property" FROM table_204_229 WHERE id = (SELECT id FROM table_204_229 WHERE "property" = 'tensile elongation') - 1
SELECT "property" FROM "table_204_229" WHERE "id" = (SELECT "id" FROM "table_204_229" WHERE "property" = 'tensile elongation') - 1
