Go Up to Blob Data Operations

There are six steps required for reading data from an existing Blob:

  1. Create a SELECT statement query that specifies selection of the Blob column (and any other columns desired) in the rows of interest.
  2. Prepare an output XSQLDA structure to hold the column data for each row that is fetched.
  3. Prepare the SELECT statement for execution.
  4. Execute the statement.
  5. Fetch the selected rows one by one.
  6. Read and processing the Blob data from each row.
