Oracle OLEDB Throws Error "DBCOLUMNFLAGS_ISFIXEDLENGTH" to Handle CHAR(n BYTE) From Linked Server With MS SQL Server (Doc ID 2484393.1)

Last updated on APRIL 17, 2023

Applies to:

Oracle Provider for OLE DB - Version 12.1.0.2 and later
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)

Symptoms

 Error occurred while querying column CHAR(n BYTE) from MS SQL Server with linked server using Oracle OLEDB provider.

 Msg 7356, Level 16, State 1, Line 1
 The OLE DB provider "OraOLEDB.Oracle" for linked server "OrclTestLink" supplied inconsistent metadata for a column.
 The column "GENDER" (compile-time ordinal 2) of object ""TEST"."TEST1"" was reported to have a "DBCOLUMNFLAGS_ISFIXEDLENGTH" of 16 at compile time and 0 at run time.

Changes

 Notes :  In Oracle, you can define the type of a string column as:
                      CHAR(15 BYTE)    – the column can hold string of up to 15 bytes,
                      CHAR(15 CHAR)   – the column can hold string of up to 15 characters,
                      Simply CHAR(15)  – the semantics depend on the value of the NLS_LENGTH_SEMANTICS parameter of the session creating the table.
             By default your table is created with byte semantics.
