Now, the user is saying that when they select from blobtable (using PL/SQL developer), blobcol contains "Value Error" for this row. Out of curiosity, I tried selecting the same record in SQL*Plus and I get the following value for blobcol: CREATE DIRECTORY MY_DIR AS '/directory/subdirectory'; DECLARE src_bfile BFILE := BFILENAME('MY_DIR', 'filename.txt'); dest_blob BLOB; BEGIN SELECT BLOBCOL into dest_blob FROM BLOBTABLE WHERE ROWID = 'ROWIDVALUE'; DBMS_LOB.

UPDATE summary_data SET current_category = (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id) WHERE EXISTS (SELECT category_id FROM products WHERE products.product_id = summary_data.product_id); If you want to test your skills using the SQL UPDATE statement, try some of our practice exercises.

I wanted to be able to write SQL Statements that allowed files to be read into the stream and update the backend database column (CLOB).

With some MSSQL and My SQL skills, I did some reading up on how Oracle can manipulate CLOB/LOB Columns using DBMS_LOB.

The Oracle UPDATE statement locates one or more rows (or all the rows) in a table and sets one or more columns to the specified values.

As with the INSERT statement, the values must either match the columns data type or one that the database can implicitly convert.

During a recent migration project for one of our customers, I needed to export certain XML rows from a Novell Sentinel 6.1 Oracle 10G R2 Hotfix 4 Database.
