how to split the column data if spaces are not there and store it into new table?

hi,

i got one requirement i.e we purchased one database , before that we are using one database for application.

now in new database the data for column is stored by merging unit+drugname+measure columns.

now my requirement is i have to use same table structure which is having previously and used for application .but i have to get data from newly purchased database table and store it into my old table.because the newly purchased database table data is hord-coded.

here i am giving one simple example and my required output , kindly have a look on it.

**Table-1**:

    CREATE TABLE MASTERT(CODE INT, DRUGNAME VARCHAR(20), ROUTE VARCHAR(20))

    INSERT MASTERT VALUES(2567,'30SESICONMG','SP')

    INSERT MASTERT VALUES(1456,'30AMERIZOMERISMG','SP')

    INSERT MASTERT VALUES(246789,'30LOCTON-ZENICMG','SP')

    INSERT MASTERT VALUES(134,'30TWENTERZARMG','SP')

Sample data:

    Code                   DRUGNAME                      ROUTE

    -----------------------------------------------------------

    2567                   30SESICONMG              SP

    1456                   30AMERIZOMERISMG         SP

    246789                 30LOCTON-ZENICMG         SP

**TABLE2**

    CREATE TABLE DRUGDESRIPTION(CODE CHAR(3), DESCRIPTION VARCHAR(50))

    INSERT DRUGDESRIPTION VALUES('SP','SPRUNPETA')

Sample data:

    CODE         DESRIPTION

    -----------------------   

    SP           SPRUNPETA

**TABLE-3**:

    CREATE TABLE DRUG

    (CODE INT,

      DRUGNAME VARCHAR(50),

      ROUTE  VARCHAR(20),

      UNIT INT,

      MEASURE VARCHAR(20)

    )

My expected output is like below

    CODE           DRUGNAME        ROUTE         UNIT         MEASURE

    ------------------------------------------------------------------

    2567          SESICON          SPRUNPETA     30           MG

    1456          AMERIZOMERIS     SPRUNPETA     30           MG

    246789        LOCTON-ZENIC     SPRUNPETA     30           MG

It means I am getting the data from `DRUGDESRIPTION` and `mastert` tables and store it into `DRUG` table.

Note that under the `drugname` column we cannot expect the length of drug name data like in some columns (`SESICON, AMERIZOMERIS, LOCTON-ZENIC`) here column length may also increase.

actually i know 30 is the unit and mg is measure and SESICON, AMERIZOMERIS, LOCTON-ZENIC are drugnames. but  there is no space in between words then how can i split it and store it.

Can anyone help me as early as possible please.

Thanks in advance.
