I have a table with a column specified as the LONG datatype. When selecting data I get the following error: "ORA-00932: INCONSISTENT DATATYPE." Is there a quick way to extract this information?

I have a table with a column specified as the LONG datatype. When selecting data I get the following error: "ORA-00932: INCONSISTENT DATATYPE." Is there a quick way to extract this information? My Oracle version is 9.2.0.4.

You can try to explicitly convert the LONG datatype to a character datatype with the TO_CHAR function:

SELECT TO_CHAR(my_long_column) FROM my_table;

You can then store the returned value to a variable defined as the VARCHAR2 datatype.

ORA-00932 using length function An article on this Web site said the length function could tell me the length of a long datatype column. However, in SQL*Plus I received the following error: "ORA-00932: inconsistent datatypes: expected NUMBER got LONG."

Correct use of CLOB datatype I have a database design where CLOB datatypes are being used in place of VARCHAR2 datatypes. The VARCHAR2 datatypes are not large. I believe this was done was to use ConText indexes for Web page searches. I need some ammunition regarding the use or incorrect use of CLOBs.

Changing datatype of one column I have an Oracle table with 8 million records. I need to change the datatype associated with one of the columns. What would be the best process for doing this? I am a .NET developer and do not know exactly how to approach this.
