The quotes around the Schema and Table Name prevented the names from being converted to uppercase.
Remove the quotes from the Table and Schema from the UPDATE statement so that it will be converted to uppercase:
For example:
UPDATE "BSQL1"."apk_pkc_TBL"
We will not convert these names to uppercase when quoted.
