CREATE TABLE table_204_882 (id NUMBER, "number" NUMBER, "builder" CLOB, "entered service" CLOB, "withdrawn" CLOB, "notes" CLOB)

what was the most reason given in the notes column ?
SELECT "notes" FROM table_204_882 GROUP BY "notes" ORDER BY COUNT(*) DESC LIMIT 1
SELECT "notes" FROM "table_204_882" GROUP BY "notes" ORDER BY COUNT(*) DESC FETCH FIRST 1 ROWS ONLY
