CHOP_UP

Undocumented odm_model_util.chop_up( p_short_stmt IN VARCHAR2, p_long_stmt IN OUT sys.dbms_sql.varchar2s, p_long_count IN OUT BINARY_INTEGER);

TBD

CLOB_TO_EXPRESSION_REC

Undocumented odm_model_util.clob_to_expression_rec(p_clob IN CLOB) RETURN sys.dbms_data_mining_transform.expression_rec;

TBD

DM_ENABLED_CHECK

Undocumented odm_model_util.dm_enabled_check;

exec odm_model_util.dm_enabled_check;

EXPRESSION_REC_TO_CLOB

Undocumented odm_model_util.expression_rec_to_clob( p_expr IN sys.dbms_data_mining_transform.expression_rec) RETURN CLOB;

TBD

TABLE_EXIST

Returns TRUE if a table exists, else FALSE

Calls DBMS_ASSERT to validate the name. odm_model_util.table_exist(p_table_name IN VARCHAR2) RETURN BOOLEAN;

BEGIN

        IF odm_model_util.table_exist('SYS.TAB$') THEN

          dbms_output.put_line('Exists');

        ELSE

          dbms_output.put_line('Not Found');

        END IF;

UPCASE

Upper cases a string.

There are multiple examples of Oracle not using the UPPER function ... but no available explanation as to why some developers feel compelled to reinvent the wheel. odm_model_util.upcase( p_out_name OUT VARCHAR2, p_in_name IN VARCHAR2);

DECLARE

       iVal dbms_id := 'Morgan';

       oVal dbms_id;

      BEGIN

        odm_model_util.upcase(oVal, iVal);

        dbms_output.put_line(oVal);

      END;
