SqlSetProp Function (Long, String, Usual) |
Namespace: XSharp.VFP
FUNCTION SqlSetProp( nStatementHandle AS LONG, cSetting AS STRING, eExpression AS USUAL ) AS LONG
Setting | Description | Read/Write |
---|---|---|
Asynchronous | Specifies whether result sets are returned synchronously (False (.F.), the default), or asynchronously (True (.T.)). | Read/write |
BatchMode | Specifies whether SqlExec( ) returns result sets all at once (True (.T.), the default), or individually with SqlMoreResults( ) (False (.F.)). | Read/write |
ConnectBusy | Contains True (.T.) if a shared connection is busy; otherwise contains False (.F.). | Read-only |
ConnectString | The login connection string. | Read-only |
ConnectTimeOut | Specifies the time to wait (in seconds) before returning a connection time-out error. If you specify 0, the wait is indefinite and a time-out error is never returned. ConnectTimeOut can be 0 to 600. The default is 15. | Read/write |
DataSource | The name of the data source as defined in the ODBC.INI file for ODBC connections. | Read/write |
DisconnectRollback |
Specifies if a pending transaction is committed or rolled back when SqlDisconnect( ) is called for the last connection handle. The default is false (.F.), indicating that a pending transaction is committed when SqlDisconnect( ) is called for the last connection handle. Specify true (.T.) to roll back a pending transaction when SqlDisconnect( ) is called for the last connection handle. Connections with automatic transaction processing are not affected by this setting. | Read/write |
DispLogin |
Contains a numeric value that determines when the ODBC Login dialog box is displayed. DispLogin may assume the following values: 1 or DB_PROMPTCOMPLETE (from Foxpro.H).1 is the default. 2 or DB_PROMPTALWAYS (from Foxpro.H). 3 or DB_PROMPTNEVER (from Foxpro.H). If 1 or DB_PROMPTCOMPLETE is specified, X# displays the ODBC Login dialog box only if any required information is missing. If 2 or DB_PROMPTALWAYS is specified, the ODBC Login dialog box is always displayed, making it possible for you to change settings before connecting. If 3 or DB_PROMPTNEVER is specified, the ODBC Login dialog box isn't displayed and X# generates an error if the required login information isn't available. Read/write. | Read/write |
DispWarnings | Specifies if error messages are displayed (True (.T.)) or are not displayed (False (.F.), the default). | Read/write |
IdleTimeout | The idle timeout interval in minutes. Active connections are deactivated after the specified time interval. The default value is 0 (wait indefinitely). | Read/write |
ODBChdbc | The internal Ado.Net DbConnection object. | Read-only |
ODBChstmt | The internal Ado.Net DbCommand object. | Read-only |
PacketSize |
The size of the network packet used by the connection. Adjusting this value can improve performance.
The default value is 4096 bytes (4K). Changing this property does not work for all providers. | Read/write |
Password | The connection password. When you create a connection with the Login dialog then this password is not always available. | Read-only |
QueryTimeOut | Specifies the time to wait (in seconds) before returning a general time-out error. If you specify 0 (the default), the wait is indefinite and a time-out error is never returned. QueryTimeOut can be 0 to 600. | Read/write |
Shared | Specifies whether the underlying connection is a shared connection (True (.T.)), or not (False (.F.)). | Read-only |
Transactions |
Contains a numeric value that determines how the connection manages transactions on the remote table. Transactions may assume the following values: 1 or DB_TRANSAUTO (from Foxpro.H).1 is the default. Transaction processing for the remote table is automatically handled. 2 or DB_TRANSMANUAL (from Foxpro.H). Transaction processing is handled manually through SqlCommit( ) and SqlRollBack( ). | Read/write |
UserId | The user identification. When you create a connection with the Login dialog then this UserId is not always available. | Read-only |
WaitTime | The amount of time in milliseconds that elapses before X# checks if the SQL statement has completed executing. The default is 100 milliseconds. | Read/write |
