LSH Datatype Limits To Avoid Errors Like ORA-910 "specified length too long for its datatype" (Doc ID 2197181.1)

Last updated on MARCH 08, 2017

Applies to:

Oracle Life Sciences Data Hub - Version 2.4.6 and later
Information in this document applies to any platform.

Goal

The Datatypes in LSH depend on Database limits. If these are exceeded, you may hit errors like ORA-910 "specified length too long for its datatype".

 

The example below reproduces when Installing a Load Set where varchar2 column value is larger than the maximum of 4000:


Apply similar steps to Smoke Test "2.24 Create a SAS Load Set", but using a sas7bdat file where a table has a VARCHAR2 column length larger than 4000:

1. Go to LSH development Work Area

2. Create new Load Set with SAS Adapter Type and create Table Descriptor using sas7bdat file with a VARCHAR2 column length larger than 4000.

3. Create Table Instance from existing Table Descriptor. It will create a column DESCRIPTION as VARCHAR2 (4005)

4. Install the Load Set. LSH displays:

Error during Workarea Install : There are errors during OWB deployment. See install log for details.

a) Per OWB log:

2016/10/10-22:45:29-PDT [63815614][CDR_RTREPOS.CDR_RTREPOS] java.sql.SQLException: ORA-00910: specified length too long for its datatype

and then, as consequence, the table cannot be created and it displays:

2016/10/10-22:45:29-PDT [63815614][CDR_RTREPOS.CDR_RTREPOS] java.sql.SQLException: ORA-00942: table or view does not exist

 

In the example above, LSH tries to create a database table and then, hits the Database Datatype limits. Per <NOTE:18506.1> OERR: ORA-910 "specified length too long for its datatype"

Error: ORA-00910 specified length too long for its datatype
---------------------------------------------------------------------------
Cause: for datatypes CHAR and RAW, the length specified was > 2000; otherwise, the length specified was > 4000.

Action: use a shorter length or switch to a datatype permitting a longer length such as a VARCHAR2, LONG CHAR, or LONG RAW
