This topic describes the paths and object names that are created and/or used by the SQL Option Server when you create various data objects in SQL Option Server locations. The storage structure and object names depend on the options you specify in your CREATE statements. In the chart, the first two columns of a given row define the condition that is described in the remaining columns of that row (by reading across).
If stogroup is sysdeflt, the location path is used as the stogroup path. When objects are created, the ..\loc-path\dbname\ path is used.
To generate file names for objects that have names greater than 8 characters (for example, 18-character table names), The SQL Option Server truncates the long name to 8 characters. If the resulting file name would not be unique, a unique file name is generated automatically.
The following list explains the abbreviations used in the chart:
| Abbreviation | Meaning |
|---|---|
| Dbname | Database name |
| Tsname | Table space name |
| Sto-name | Storage Group name |
| Dbsto-path | Disk drive and path defined for the database (DB) stogroup. |
| Tssto-path | Disk drive and path defined for the table space (TS) stogroup. |
| Loc-path | Disk drive and path defined for the location. |
This chart does not list all possible combinations of creation conditions. Only the more common conditions are shown.

| Stogroup | Volumes Vcat (No path defined) |
..\loc-path\dbname\ path is used when objects are created | Sto-name you enter | n/a | n/a |
| Stogroup | Volumes Vcat XdbVolPath |
XdbVolPath you enter in SYSIBM.SYSVOLUMES (for example, c:\sto-path) |
Sto-name you enter | n/a | n/a |
| Database | ------ | c:\loc-path\dbname\ | SYSDEFLT | DBname you enter | n/a |
| Database | Stogroup | c:\DBsto-path\ | Sto-name you enter | DBname you enter | n/a |
| Table Space | Database | c:\loc-path\dbname\ | SYSDEFLT | DBname you enter | TSname you enter |
| Table Space | Database Stogroup (Sto-path for the named stogroup is missing from SYSIBM. SYSVOLUMES) |
c:\loc-path\dbname\ | SYSDEFLT | DBname you enter | TSname you enter |
| Table Space | Database Stogroup (Sto-path exists in SYSIBM. SYSVOLUMES and on op system) |
c:\TSsto-path\ | Sto-name you enter | DBname you enter | TSname you enter |
| Table | ------ | c:\loc-path\DSNDB04\*.tab | SYSDEFLT | DSNDB04 | TSname is first 8 characters of table name (or system generated unique name, if needed) |
| Table | Database (DB has NO stogroup) |
c:\loc-path\dbname\*.tab | SYSDEFLT | DBname you enter | TSname is first 8 characters of table name (or system generated unique name, if needed) |
| Table | Database (DB has a stogroup) |
c:\DBsto-path\*.tab | Same sto-name as the database's stogroup | DBname you enter | TSname is first 8 characters of table name (or system generated unique name, if needed) |
| Table | Database Tablespace (DB has NO stogroup; TS has NO stogroup) |
c:\loc-path\dbname\*.tab | SYSDEFLT | DBname you enter | TSname you enter |
| Table | Database Tablespace (DB has NO stogroup; TS has a stogroup) |
c:\TSsto-path\*.tab | Same sto-name as the table space's stogroup | DBname you enter | TSname you enter |
| Table | Database Tablespace (DB has a stogroup; TS has NO stogroup) |
c:\DBsto-path\*.tab | Same sto-name as the database's stogroup | DBname you enter | TSname you enter |
| Table | Database Tablespace (DB has a stogroup; TS has a stogroup) |
c:\TSsto-path\*.tab | Same sto-name as the table space's stogroup | DBname you enter | TSname you enter |
| Index | Tablename (DB has NO stogroup) |
Same path as associated table..\*.idx and ..\*.ptr | SYSDEFLT | DBname to which associated table belongs | Index space name is same as index name |
| Index | Tablename (DB has a stogroup) |
Same path as associated table..\*.idx and ..\*.ptr | Same sto-name as the database's stogroup | DBname to which associated table belongs | Index space name is same as index name |
| Index | Tablename Stogroup |
Same path as associated table..\*.idx and ..\*.ptr | Sto-name you enter | DBname to which associated table belongs | Index space name is same as index name |
