The ODBC Client has a connection attribute to monitor the status of connection pools. This attribute, which is described in the following table, allows your application to fetch statistics for the pool to which a connection belongs.
| Connection Attribute | Description |
| SQL_ATTR_POOL_INFO Value: SQL_GET_POOL_INFO |
Calling SQLGetConnectAttr (SQL_ATTR_POOL_INF, SQL_GET_POOL_INFO) returns a PoolInfoStruct that contains the statistics for the connection pool to which this connection belongs. This PoolInfoStruct is defined in qesqlext.h. For example:SQLGetConnectAttr(hdbc, SQL_ATTR_POOL_INFO, PoolInfoStruct *, SQL_LEN_BINARY_ATTR(PoolInfoStruct), &len);This is a read-only connection attribute. The driver returns an error if SQLSetConnectAttr (SQL_ATTR_POOL_INFO) is called. |
