Displays the content of a single BLOB or CLOB cell from the SQL
Console result grid.
Opens by clicking the ... button on the right edge of a
BLOB or CLOB cell.
The viewer selects a mode automatically based on cell type and content:
| Condition | Display |
|---|---|
| CLOB (text) | Read-only text area. Title bar shows character count and byte size. |
| BLOB — recognised image | Image rendered in a canvas (JPEG, PNG, GIF, BMP, TIFF, ICO, WMF). |
| BLOB — other binary | Hex dump of the first 4096 bytes. Title bar shows the full size. |
| Empty / NULL | Empty display, size 0. |
When the cell was truncated by the BLOB budget or per-cell cap, the viewer shows only the truncated portion.
Download Full Content — fetches the complete value from the server, bypassing the budget for this cell only. The button is shown when all of the following conditions are met:
If the button is not shown and a red label explains that the download
is unavailable, re-run the query with SELECT * or include
all primary key columns explicitly. If the column is aliased or the
source table cannot be determined, increase Max KB in
the SQL Console toolbar and re-run the query to receive the full value
directly.
| Button | Availability | Action |
|---|---|---|
| Save to File | When content is complete (not truncated, or after downloading) | Saves to disk. CLOBs as UTF-8 with BOM; BLOBs with format suggestions based on detected image type. |
| Download Full Content | When content is truncated and all PK columns are present in the result | Fetches the complete value and enables Save to File. |
| Close | Always | Closes the viewer. |
When content is truncated but the download is unavailable (missing or partial primary key, or aliased column), a red label in the button bar explains why and how to enable the download.
