Hello Experts,
I found this group in google while I was searching for how to auto
increment strings with the numbers in it.
I am switching database from access to oracle 11g. I have create all the
required tables, but I am stuck at one point. The previous person who
created access database had auto increment with SG0101, SG0102,........ In
oracle, I know we can auto increment primary keys but only with the numbers
not with characters.
So I have customerid which is a primary key and it automatically increments
the number, but I have one more column with memberid where I am inserting
all the ids that start with SG0101 bla bla.....
I already have 800 member ID's that start with SG, but that value doesnt
automatically increment, because I dont have any sequence or trigger to do
that.
So how do I create a sequence and trigger that will automatically start
value with SG and keeps on auto incrementing?
Here is the table info:
CREATE TABLE "CUSTOMERS"
( "CUSTID" NUMBER,
"MEMBERID" VARCHAR2(30),
"FNAME" VARCHAR2(30),
"MNAME" VARCHAR2(30),
"LNAME" VARCHAR2(30),
"CONTACTNAME" VARCHAR2(30),
"BNAME" VARCHAR2(255),
"FEDERALID" VARCHAR2(30),
"BADDRESS" VARCHAR2(255),
"BCITY" VARCHAR2(30),
"BSTATE" VARCHAR2(2),
"BZIPCODE" VARCHAR2(10),
"MAILADDRESS" VARCHAR2(100),
"MCITY" VARCHAR2(30),
"MSTATE" VARCHAR2(2),
"MZIPCODE" VARCHAR2(10),
"TELEPHONE" VARCHAR2(13),
"CELLPHONE" VARCHAR2(13),
"FAX" VARCHAR2(13),
"EMAIL" VARCHAR2(75),
"JOINDATE" TIMESTAMP (6) WITH LOCAL TIME ZONE,
"STATUS" VARCHAR2(8),
"ZONE" VARCHAR2(5),
CONSTRAINT "CUSTOMERS_PK" PRIMARY KEY ("CUSTID") ENABLE
Any help will be appreciate it.
