{Test 6: Blob Handling}

{
  1. Create an empty database and populate with a single table and stored procedure
     returning a blob.

  2. Show the character sets available (List RDB$CHARACTER_SETS)

  3. Select all from new table and show metadata.

  4. Insert row and include WIN1252 characters known to be in two byte UTF8, plus Fixed point

  5. Select all from new table

  6. Use Update Query to set blob field with plain text loaded from file

  7. Select all from new table

  8. Add another row with a null blob

  9. Update this row's blob field with a copy of the first row (demo of blob assignment)

  10. Select all from new table.

  11. Execute Stored proc and display results

  12. Drop Database and repeat above but with WIN1252 and  no default connection character set.
