Use these iSeries™ Access ODBC driver connection string keywords to change Server properties of the ODBC connection.
The following table lists connection string keywords for Server properties that are recognized by the iSeries Access ODBC driver:
| Keyword | Description | Choices | Default |
|---|---|---|---|
| CMT or CommitMode | Specifies the default transaction isolation level. | 0 = Commit immediate (*NONE) 1 = Read committed (*CS) 2 = Read uncommitted (*CHG) 3 = Repeatable read (*ALL) 4 = Serializable (*RR) |
2 |
| CONNTYPE or ConnectionType | Specifies the level of database access for the connection. | 0 = Read/Write (all SQL statements allowed) 1 = Read/Call (SELECT and CALL statements allowed) 2 = Read-only (SELECT statements only) |
0 |
| DATABASE | Specifies the iSeries relational database (RDB) name
to connect. Note, this option is only valid to V5R2 iSeries servers.
This option will be ignored when connecting to earlier pre-V5R2 servers.
Special values for this option include specifying an empty-string or *SYSBAS. An empty-string indicates to use the user-profile's default setting for database. Specifying *SYSBAS will connect a user to the SYSBAS database (RDB name). |
iSeries relational database name | empty-string |
| DBQ or DefaultLibraries | Specifies the iSeries libraries to add to the server
job's library list. The libraries are delimited by commas or spaces, and *USRLIBL
may be used as a place holder for the server job's current library list. The
library list is used for resolving unqualified stored procedure calls and
finding libraries in catalog API calls. If *USRLIBL is not specified, the
specified libraries will replace the server job's current library list. Note: The
first library listed in this property will also be the default library, which
is used to resolve unqualified names in SQL statements. To specify no default
library, a comma should be entered before any libraries.
|
iSeries libraries Only 25 libraries are supported in a library list on a connection to a pre-V5R1 server. 75 entries are supported on a V5R1 and later servers. Entries over 75 are ignored. |
QGPL |
| MAXDECPREC or Maximum Decimal Precision | Specifies the maximum precision of decimal data that will be returned. | 31 or 63 | 31 |
| MAXDECSCALE or Maximum Decimal Scale | Specifies the maximum scale used in arithmetic calculations involving decimal data. This value must be less than the value of MAXDECPREC. | 0 – 63 | 31 |
| MINDIVSCALE or Minimum Divide Scale | Specifies the minimum scale used in arithmetic calculations involving decimal data. | 0 – 9 | 0 |
| NAM or Naming | Specifies the naming convention used when referring to tables. | 0 = "sql" (as in schema.table) 1 = "system" (as in schema/table) |
