When I query against a database, certain columns of data in the grid are coming back blank, no data.
Example... Table SOME_TBL has column COL1 which is of datatype nvarchar2. A query run for SOME_TBL returns all records and values except for values in only the COL1 column.
If this same query is run in a different version of Toad or SQL Plus there is no problem with the data displaying for COL1.
This is a problem in both the editors grid (F5 and F9) and in Schema Browsers table | data tab.
Mismatch in Oracle client and database versions. Oracle has limited support for the use of an 8i client with 10g+ database.
Please upgrade the Oracle client to a version that more closely matches the version of the newest database version.
