Storing images in relational database tables is a common task in software development. SQL Server offers a simple and efficient mechanism to store binary data, such as images, within database tables using the image data type.
Inserting Images Into a Database
To insert an image into a database table, you can use the following query:
INSERT INTO tableName (ImageColumn) SELECT BulkColumn FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img
Here, tableName is the name of the table, ImageColumn is the name of the column that will store the image, image..Path..here is the physical path to the image file, and Single_Blob indicates that the image is stored as a single, large object (LOB).
Example
Consider the following query that inserts an image named "image.jpg" into the ImageColumn column of the FEMALE table:
INSERT INTO FEMALE (ImageColumn) SELECT BulkColumn FROM Openrowset( Bulk 'C:\Users\John Doe\Pictures\image.jpg', Single_Blob) as img
Retrieving Images From a Database
To retrieve an image from a database table, you can use the following query:
SELECT ImageColumn FROM tableName WHERE ID = @ID
Here, @ID is a placeholder for the primary key value of the record containing the image.
You can then extract the image from the ImageColumn field and display it as desired.
