ATTACH
Attaches a TurboIMAGE/XL database to an SQL DBEnvironment.
Syntax
AT[TACH] [WITH OWNER=OwnerName]
Parameters
OwnerName specifies an owner for all SQL objects that need to be
created for the attached TurboIMAGE/XL database. This name
can be up to 17 bytes in length and can be made up of any
combination of letters (A to Z), decimal digits (0 to 9),
$, #, @, or _ (underscore). However, the first character
cannot be a decimal digit or an underscore. Lowercase
letters are automatically converted to uppercase letters.
Note that group and account names are not included in the
OwnerName parameter.
If this parameter is omitted, the owner name defaults to
the name of the TurboIMAGE/XL database defined in the most
recent SET TURBODB command.
Prerequisites
* SET SQLDBE issued.
* SET TURBODB issued.
* DBA authority.
* Database detached.
Description
Use the ATTACH command to attach a TurboIMAGE/XL database to a
DBEnvironment. This command can only be used after the database name and
the DBEnvironment name have been specified with SET commands.
When a database is attached to a DBEnvironment, only the DBC is defined
as an IMAGE/SQL user and default data type mapping is performed. Once
attached, ATCUtil commands can be used to update this default
information. Refer to the ADD USER, UPDATE USER, UPDATE TYPE, and SPLIT
commands for more information.
A database already attached to a specific DBEnvironment cannot be
reattached. If you attempt to do this, an error message is issued.
To attach databases with the same database name but in different groups
and accounts to the same DBEnvironment, you must use the OwnerName
parameter to specify a different owner name for all but the first such
database you attach.
[REV BEG]
If the DBEnvironment does not exist, IMAGE/SQL displays this message:
DBE does not exist, do you want to create one? [Y/N] :
If you reply 'Y', a DBEnvironment and DBE files are automatically created
for you. The files created are:
-------------------------------------------------------------------------------------------
| |
| File Created File Name |
| |
-------------------------------------------------------------------------------------------
| |
| DBE CON file DBEnvironment-name |
| |
| DBE FILE DBEnvironment-nameFL |
| |
| LOG FILE DBEnvironment-nameLG |
| |
| ATCINFO file DBEnvironment-nameCR |
| |
-------------------------------------------------------------------------------------------
For example, if you issue the command
SET SQLDBE MYDBE
and the DBEnvironment MYDBE does not exist, these files are created:
MYDBE, MYDBEFL, MYDBELG, and MYDBECR.
The default size of DBE FILE and LOG FILE is 1000 pages.[REV END]
Example
In the following example, SALES is attached to PARTSDBE. The accompanying
message summarizes the mapping that took place during the attach.

To see the specific mapping for each data set and field, use the DISPLAY
MAP command. In the example below, the display notes that the data type
mapping performed for the mapped column CREDIT_RATING is imprecise. Also
noted is the splitting of the compound source field OTHER_VENDORS into
three mapped columns.
