Query based inserting or updating of blob
And you don't actually store the image in the database, you just store the path (or just the filename) in the DB.Then your code elsewhere uses this file name to access the file.
In addition, the table must have a UNIQUEIDENTIFIER column with the ROWGUIDCOL attribute.Note that braces are not required around the table name as the query builder will handle that automatically. That is, all methods (except execute()) return the query object itself allowing method calls to be chained.In many cases, that means the query object will not need to be saved to a variable at all.There are different ways in which a DBA can enable the FILESTREAM feature, to know how you can refer to my previous tip titled Different ways to enable FILESTREAM feature of SQL Server 2008.However, in order to enable the FILESTREAM feature you need to be a member of SYSADMIN or SERVERADMIN fixed server role.The fields() method takes a single associative array that specifies what fields to set to what values when the specified conditions are met.
Note that unlike Insert queries, Update Query::fields() only accepts an associative array.
Also, the order of fields in the array and the order in which methods are called are irrelevant.
The above example is equivalent to the following query: .
Click on that and SQL Developer will display the BLOB data in picture form.
Have something other than a picture stored in that BLOB? Save it to a file, then use the Log panel to quickly open your file.
You’ve also got large objects which are composed of text – that would be a CLOB.
