I'm using Oracle SQL Developer and I'm trying to add images from a folder on my desktop to the database. I have a table consisting of:
id number
Name varchar
description clob
thumbnail blob
image ordimage
filename varchar2
I want to be able to add an image to this table.
Is there a way I can manually add them or is their any code tips or help I can get?
In Sql-Developer, you neet to click on the table on the right side,
then select "Data" tab, then insert new row (or select existing row),
next click to BLOB column, on the following dialog click to "Load" option,
then select an image and upload it to the table from local disc

I've been used to quickly uploading a CSV file to append data to an existing table in BigQuery.
I've made the new table name the same as the existing table, and I've then had options to overwrite or append data to the existing table.
This seems to have changed in the past few days and there is a new BigQuery console UI.
When I try and create a new table from a CSV file upload, under the table name field it currently says:
Unicode letters, marks, numbers, connectors, dashes or spaces allowed.
The job will create the specified destination table if needed, or the
table must be empty if it already exists.
However, when I try and create a table with the same name as an existing table (even though the existing table is empty), I get a red warning saying:
Table already exists
Does anyone know if this feature has now been removed or how to easily append data?
The long way round is to upload a CSV to a new table, then query the new table and set the destination to append or overwrite an existing table. Not ideal, particulalry having to define a new table schema.
In order to append a CSV file to an existing BigQuery table when using the Console, please follow the instructions below:
In the Explorer panel, expand your project and select a dataset.
Expand the Actions option and click Open.
In the details panel, click Create table.
On the Create table page, in the Source section:
For Create table from, select Upload.
Browse file from system
On the Create table page, in the Destination section:
For Dataset name, choose the appropriate dataset.
In the Schema section, for Auto detect, check Schema and input parameters to enable schema auto detection. Alternatively, you can manually enter the schema definition
Click Advanced options.
For Write preference, choose Append to table

I am working on a ssrs report. I have a table and it is linked to a database query.
Query returns a field which includes image urls of every item.
For example:
ID Name URL
1 Line1 https://www.servername.com/images/a.jpg
2 Line2 https://www.servername.com/images/b.jpg
Then i add an image from toolbox to table's last cell. Then from Image Properties, i choose database, then i choose database field and MIME type then i click OK.
After i run the report, i see crosses instead of image. Why is it happening? How can i show the images properly?

Thanks.
when you set the source to database you are saying that the image is stored in the database. What you actually have stored is a link, so you need to use image source external and add the data field to the expression for the "use this image".
Select External - then in the dropdown for the "Use this Image" select the data field that has the url in it.
At run time it will pull the url from the database and show the image.

I want to retrieve BLOB data from database table to Display Image Item called P4_COMPANY_LOGO
I have selected the source for Display image item as SQL Query (Return Single Value):
select company_logo from companies where company_id=10;
But when I run the page it immediately return this Error:
P4_COMPANY_LOGO has to have a valid BLOB column as source.
Help Please!..
Maybe you don't have the item properties quite right. This would work:
I have a varbinary(max) column that is storing images in an SQL database.
I am working on a newdb script, where an application creates a new instance of the db and populates a few of the tables. One of those tables I am working on is initializing that image column.
In order to do this, I printed the contents of the column using a select statement and pasted the content into the insert statement of the newdb script. This appeared to work initially, but the image didn't load correctly.
So I compared the DATALENTH() of the original data (5469988) and the new data (21839). It appears the Microsoft SQL Server management Studio - 2014 cut off the data why I copied it from the original db at a certain point. I need to be able to get the entire content of the column. Any ideas?
select cast(convert(varchar(max), VarBinaryMaxColumn, 1) as xml) from Table
Instead of copying/pasting, right-click on the results and do 'Save Results As...', and that should export the full contents. Funny thing is setting the query output to text or file explicitly will still truncate long data values.
If you copy and paste your limited to the query result options. Mostly columns will be cut of after a certain lenght (often 256 chars).
You can select in the top bar "save result as..." which will prompt you an dialog for data export.
You can use the data export wizard too.
I wrote a servlet program to upload an image to Oracle table. I am using Oracle 10g version.
I created the table using
create table insertimage( image BLOB);
The table was created successfully. My servlet shows image uploaded successfully. Even when I delete using
delete from insertimage;
it shows successful row deletion.
But when I try to see the table content using
select * from insertimage;
it gives me
ORA-00932: inconsistent datatypes: expected NUMBER got BLOB error.
So how can I check if the image has been successfully uploaded or not directly in the Oracle table?
There are lot of third party IDEs which you can use - a good free one would be Oracle's own SQL Developer
Double click on the table from the object tree. On the "Data" tab, click the "..." button with the BLOB column & then click the "View as Image" checkbox
