Following is a list of connection parameters that can be supplied to the ASE OLE DB Provider.
Property names |
Description |
Required |
Default value |
---|---|---|---|
User ID, UserID, UID |
A case-sensitive user ID required to connect to the ASE server. |
Yes |
None |
PWD, Password |
A case-sensitive password to connect to the ASE server. |
No, if the user name does not require a password. |
Empty |
Server |
The name or the IP address of the ASE server. |
No, if data source is specified. |
Empty |
Port |
The port number of the ASE server. |
No, if data source is specified. |
Empty |
AnsiNull |
Strict compliance where you cannot use “= NULL.” Instead, you must use “IsNull.” |
No |
1 |
ApplicationName |
The name ASE uses to identify the client application. |
No |
Empty |
BufferCacheSize |
Keeps the input and output buffers in pool. When large results will occur, increase this value to boost performance. |
No |
20 |
CharSet |
The designated character set. The specified character set must be installed on the ASE server. Starting with version 15.0, the charset behavior has changed. If you want to use the ASE server's charset, you must specify it in the connection properties with Charset=ServerDefault. Otherwise, the driver picks up the charset which the client specifies, or gets it from the system environment variables in the order of LC_CTYPE and LANG. If both the environment variables have not been defined, it uses the value iso_1. |
No |
Empty |
ClientHostName |
The name of the client host passed in the login record to the server. |
No |
Empty |
ClientHostProc |
The identity of the client process on this host machine passed in the login record to the server. |
No |
Empty |
CRC |
By default, the driver returns the total records updated when multiple update statements are executed in a stored procedure. This count will also include all updates happening as part of the triggers set on an update or an insert. Set this property to 0 if you want the driver to return only the last update count. |
No |
1 |
DataIntegrity |
Enables Kerberos Data Integrity. |
No |
0 (disabled) |
Data Source |
The Data Source you want to connect in Server:Port format. |
No, if server and port are specified. |
Empty |
DSPassword |
The password used to authenticate on the LDAP server, if the LDAP server does not allow anonymous access. The password can be specified in the DSURL as well. |
No |
Empty |
DSPrincipal |
The user name used to authenticate on the LDAP server, if the LDAP server does not allow anonymous access. The Principal can be specified in the DSURL as well. |
No |
Empty |
DSURL |
The URL to the LDAP server. |
No |
Empty |
DynamicPrepare |
When set to 1, the driver sends SQLPrepare calls to ASE to compile/prepare. This can boost performance if you use the same query repeatedly. |
No |
0 |
EnableServerPacketSize |
Allows ASE server versions 15.0 or later to choose the optimal packetsize. |
No |
1 |
EncryptedPassword |
Specifies if password encryption is enabled: 0 indicates password encryption is disabled, 1 indicates password encryption is enabled. |
No |
0 |
Encryption |
The designated encryption. Possible values: ssl. |
No |
Empty |
HASession |
Specifies if high availability is enabled: 0 indicates high availability disabled, 1 high availability enabled. |
No |
0 |
Initial Catalog, Database |
The database to which you want to connect. |
No |
Empty |
Language |
The language in which ASE returns error messages. |
No |
Empty – ASE uses English by default. |
LoginTimeOut |
Number of seconds to wait for a login attempt before returning to the application. If set to 0, the timeout is disabled and a connection attempt waits for an indefinite period of time. |
No |
10 |
MutualAuthentication |
Enables Kerberos Mutual Authentication. |
No |
0 (disabled) |
PacketSize |
The number of bytes per network packet transferred between ASE and the client. |
No |
Server determined when driver is connected to ASE 15.0 or later. For older ASE servers the default is 512. |
QuotedIdentifier |
Specifies if ASE treats character strings enclosed in double quotes as identifiers: 0 indicates do not enable quoted identifiers, 1 indicates enable quoted identifiers. |
No |
0 |
ReplayDetection |
Enables Kerberos Replay Detection. |
No |
0 |
RestrictMaximum PacketSize |
If the you have memory constraints when EnableServerPacketSize is set to 1, then set this property to an int value in multiples of 512 to a maximum of 65536. |
No |
0 |
SecondaryPort |
The port number of the ASE server acting as a failover server in an active-active or active-passive setup. |
Yes, if HASession is set to 1 |
Empty |
SecondaryServer |
The name or the IP address of the ASE server acting as a failover server in an active-active or active-passive setup. |
Yes, if HASession is set to 1 |
Empty |
ServerInitiated Transactions |
When SQL_ATTR_AUTOCOMMIT is set to “1,” Adaptive Server starts managing transactions as needed. The driver issues a set chained on command on the connection. Older ODBC Drivers do not use this feature and manage the job of starting transactions. Set this property to’'0’ if you want to maintain the old behavior or require that your connection not use “chained” transaction mode. |
No |
1 |
TextSize |
The maximum size of binary or text data that will be sent over the wire. |
No |
Empty. ASE default is 32K. |
