Problems with TEXT BLOB

Post by HK » Wed 05 Dec 2007 11:35

Hello friends.

I'm using the last version of CoreLab(4.20) in Deplhi 2007 with DBExpress 4. If I try to update or insert a TEXT BLOB on compare of two TEXT fields, the system returns a error message : "Error : Operand Type Clash : varbinary is incompatible with text. ". How to resolve this issue ?

You can take a look at the Pictures demo of DbxSda. It demonstrates how to work with IMAGE fields. Approach for working with TEXT fields is the same.
You can also use TMemoField instead of TBlobField that is used in the Demo. TMemoField is a descendant of TBlobField.
