Barry | I noticed EDB 2.13 B2 cannot return a Clob or Blob in a subselect.
Example: Select t1.FullName, (Select Image from Pictures where Name_Id=t1.Name_Id) from People t1; The value returned for a Clob is an empty string and a Blob is of 0 bytes. (Neither values returned are NULL so it finds the row ok). If I replace "Image" with a text column like "Image_Name" it returns the text for Image_Name just fine in the subselect. But the Subselect cannot return a Clob or Blob value. Why? Is this a bug or has it been fixed in a later EDB version? Or is this some sort of weird ANSI standard used to torment programmers? ![]() TIA Barry |

I see the same here with 2.16b2. Looks like a bug, you should report it. A possible workaround in case of CLOB type is to cast it as varchar. -- Fernando Dias [Team Elevate] |

Thinking better, even for CLOB, casting it as varchar is not a real workaround ... -- Fernando Dias [Team Elevate] |
