The prefix length goes with the index definition, not the column definition. See http://www.mysql.com/doc/en/CREATE_TABLE.html : | Only the MyISAM table type supports indexing on BLOB and TEXT | columns. When putting an index on a BLOB or TEXT column you MUST | always specify the length of the index: | | CREATE TABLE test (blob_col BLOB, INDEX(blob_col(10))); -- Keith C.
