NO for all objects created in Oracle... 30 chars is the max. R -----Original Message----- Sent: Thursday, June 12, 2003 11:30 AM To: Multiple recipients of list ORACLE-L
hi, We use Oracle 8 DB. I am not a Oracle technical guy. So lemme try explaining the problem. We need to create tables with columns, whose names(column-names) are more than 30 characters long. This is being restricted because, all columns of all tables have entries in a table called 'col'. Thit table is defined as: SQL> desc col Name Null? Type ----------------------------------------- -------- ---------------------------- TNAME NOT NULL VARCHAR2(30) COLNO NOT NULL NUMBER CNAME NOT NULL VARCHAR2(30) COLTYPE VARCHAR2(106) WIDTH NOT NULL NUMBER SCALE NUMBER PRECISION NUMBER NULLS VARCHAR2(19) DEFAULTVAL LONG CHARACTER_SET_NAME VARCHAR2(44) SQL> since CNAME is defined as VARCHAR2(30), we are forced to retrict column names to a max of 30 characters long. For eg. create table T1(xxxxxxxxxxxxxxxxxxxxxxxxxxxxx31 varchar2(50)); The above statement will be rejected with the error: * ERROR at line 1: ORA-00972: identifier is too long However, the statement "create table T1(xxxxxxxxxxxxxxxxxxxxxxxxxxxx30 varchar2(50))" Succeeds in creating the table; I guess this table col is created by the system itself. how can we change this size So that the 30 character restriction in column names can be avoided??? baski **************************Disclaimer************************************ Information contained in this E-MAIL being proprietary to Wipro Limited is 'privileged' and 'confidential' and intended for use only by the individual or entity to which it is addressed.
