TEXT and BYTE Objects Are Created Before the Data Row Is Inserted

When TEXT or BYTE data is written to disk, the row to which it belongs might not exist yet. During an insert, for example, the TEXT or BYTE data is transferred before the rest of the row data. After the TEXT or BYTE object is stored, the data row is created with a 56-byte descriptor that points to its location. For a description of how TEXT and BYTE data types are stored physically, refer to the section on the structure of a dbspace blobpage in the disk storage and structure chapter of the IBM Informix: Administrator's Reference.
