The four BLOB types are very similar to each other; the only difference is the maximum amount of data each can store. Sometimes, for the security reasons, you may need to store large data objects e.g., images, PDF files, and videos in the MySQL database.MySQL provides a BLOB type that can hold a large amount of data. SET mime = :mime, FROM files

The actual BLOB column type is of four types-TINYBLOB, BLOB, MEDIUMBLOB and LONGBLOB. To insert the content of a file into a BLOB column, you follow the steps below: First, open the file for reading in binary mode.

Simple code examples will be presented within this section, and a The following example creates a table that defines a BLOB column named blarge: CREATE TABLE t1 (id INTEGER ,blarge BLOB(128K)); The following example shows a stored procedure that inserts part of a BLOB into one table and the remaining part of the BLOB into another table: CREATE TABLE LocalData(ld_ID INTEGER, ld_DATA BLOB);

A BLOB is a binary large object that can hold a variable amount of data. The maximum value of a BLOB object is specified by the available memory and the communication package size. WHERE id = :id;""SELECT mime, In addition, BLOB strings do not hold character data.

* insert blob into the files table

To insert the content of a file into a BLOB column, you follow the steps below:To update a BLOB column, you use the same technique as described in the inserting data into a BLOB column.
