Use these iSeries™ Access ODBC driver connection string keywords to change other properties of the ODBC connection.
The following table lists other connection string keywords that are recognized by the iSeries Access ODBC driver:
| Keyword | Description | Choices | Default |
|---|---|---|---|
| ALLOWPROCCALLS | Specifies whether stored procedures can be called when the connection attribute, SQL_ATTR_ACCESS_MODE, is set to SQL_MODE_READ_ONLY. | 0 = Do not allow stored procedures to be called 1 = Allow stored procedures to be called |
0 |
| DB2SQLSTATES | Specifies whether or not to return ODBC-defined SQL States or DB2® SQL States. Refer to the DB2 UDB SQL Reference for more details on the DB2 SQL States. This option should be used only if you have the ability to change the ODBC application's source code. If not, you should leave this option set to 0 as most applications are coded only to handle the ODBC-defined SQL States. | 0 = Return ODBC-defined SQLStates 1 = Return DB2 SQL States |
0 |
 DATETIMETOCHAR or ConvertDateTimeToChar |
Specifies one or more options on how date, time, and
timestamp data types are reported to an application. To specify multiple options
add together the values for the options. This option supports cases in which
date values such as 24:00:00 are used. |
To determine the value for this keyword, add the values
below that are associated with each option that you want. 0 = Continue to map the DATE, TIME, and TIMESTAMP data types as SQL_TYPE_DATE, SQL_TYPE_TIME, and SQL_TYPE_TIMESTAMP 1 = Return DATE data type as SQL_CHAR 2 = Return TIME data type as SQL_CHAR 4 = Return TIMESTAMP data type as SQL_CHAR |
0 |
| DBCSNoTruncError | Specifies whether or not to report a DBCS string conversion overflow error as an ODBC trunctation error. | 0 = Report DBCS string conversion overflow error as
ODBC truncation error 1 = Ignore truncation error |
0 |
| DEBUG | Specifies one or more debug options. To specify multiple debug options add together the values for the options that you want. In most cases you will not need to set this option. | To determine the value for this keyword, add the
values below that are associated with each option that you want. 2 = Return SQL_IC_MIXED for the SQL_IDENTIFIER_CASE option of SQLGetInfo 4 = Store all SELECT statements in the package 8 = Return zero for the SQL_MAX_QUALIFIER_NAME_LEN option of option of SQLGetInfo 16 = Add positioned UPDATEs / DELETEs into packages 32 = Convert static cursors to dynamic cursors 64 = Send the entire column size worth of data for variable length fields (VARCHAR, VARGRAPHIC, BLOB, etc.) Note, set this option with caution as this can have an adverse impact on performance. 128 = Subtract one from the SQLBindParameter sourcelength if the last character in the buffer is a null-terminator character. 256 = Ignore data decimal errors 512 = Ignore case warnings (SQL0402) for scrollable cursors 1024 = Disable variable length compression 2048 = Return no support for SQL_CVT_DATE when calling the SQLGetInfo's SQL_CONVERT_TIMESTAMP option. 32768 = If the result of a query results in a column being divided by 0, return a NULL value instead of an error. |
0 |
| TRUEAUTOCOMMIT | Specifies how to handle autocommit support. In past ODBC drivers, turning autocommit on resulted in the server running under the *NONE isolation level. Now autocommit can run under any isolation level. Applications that require strict conformance to the SQL specification should use setting 1. Note that this setting requires that all files be journaled. Setting 0 offers better performance for most applications. See the SQL reference for further information on Transaction Isolation levels. | 0 = run autocommit under the *NONE isolation level
|
0 |
| NEWPWD |
Specifies a new password used to override the current
user's iSeries password.
This option is only honored if set by an application. When using this option,
the UID and PWD keywords should also be specified. |
New password to use |
none |
| XALCS or XALooselyCoupledSupport | Specifies whether locks are shared between loosely coupled distributed transaction branches. | 0 = Locks are not shared 1 = Locks are shared |
1 (for Windows®) 0 (for Linux®) |
| XALOCKTIMEOUT | Specifies the maximum amount of time (in seconds) that a distributed transaction waits on a lock request before timing out. | 0 = Use the default system setting 0 – 999999999 = the number of seconds to wait |
0 |
| XATXNTIMEOUT or XATransactionTimeout | Specfies the amount of time (in seconds) that a distributed transaction waits before timing out. | 0 = Wait indefinitely for the transaction to finish 0 – 999999999 = the number of seconds to wait |
0 |
