Hello to all. So: Delphi 5, Firebird 1.5 in a SQL write. Select* from table where upper(name) like 'GRG' Return me error. Conversion error from string Blob The field name is a type BLOB SUBtype 1-text. The manual for SQL which I wrote that the upper should also work with strings and BLOB subtype text. It is a guide for Interbase 6. Where could be a problem?
