nStatementHandle

Specifies the statement handle to the data source returned by SQLCONNECT(В ).

cSetting

Specifies the setting. The following table lists the values for cSetting.

Setting	Description
Asynchronous	Specifies whether result sets are returned synchronously (False (.F.), the default), or asynchronously (True (.T.)). Read/write.
BatchMode	Specifies whether SQLEXEC(В ) returns result sets all at once (True (.T.), the default), or individually with SQLMORERESULTS(В ) (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. Read/write.
DisconnectRollback	Specifies if a pending transaction is committed or rolled back when SQLDISCONNECT(В ) is called for the last connection handle. The default is false (.F.), indicating that a pending transaction is committed when SQLDISCONNECT(В ) is called for the last connection handle. Specify true (.T.) to roll back a pending transaction when SQLDISCONNECT(В ) 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, Visual FoxPro 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 Visual FoxPro generates an error if the required login information isn't available. 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 ODBC connection handle, which may be used by external library files (FLL files) to call ODBC. Read-only.
ODBChstmt	The internal ODBC statement handle, which may be used by external library files (FLL files) to call ODBC. 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). Read/write
Password	The connection password. 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(В ) and SQLROLLBACK(В ). Read/write.
UserId	The user identification. Read-only.
WaitTime	The amount of time in milliseconds that elapses before Visual FoxPro checks if the SQL statement has completed executing. The default is 100 milliseconds. Read/write.

eExpression

Specifies the value for the setting you designate with cSetting. If you omit eExpression, the default value is restored for the setting.

Numeric data type. SQLSETPROP( ) returns 1 if it is successful. Otherwise, it returns – 1 if a connection level error occurs or – 2 if an environment level error occurs.

You can use SQLGETPROP(В ) to return the current value for a specified setting.

Note:
You must disable the Open Database Connectivity (ODBC) login dialog box to support SQL pass through with Microsoft Transaction Server. To disable the ODBC login dialog box, use the statement SQLSETPROP(cStatementHandle, 'DispLogin', 3), where cStatementHandle is the statement handle returned by SQLCONNECT(В ). You can also disable the ODBC login dialog box in the Connection Designer.

The ConnectTimeOut option can be set only at the Visual FoxPro level and has no equivalent at the connection level. You can set all other options at either the connection or the Visual FoxPro level. Each option set at the Visual FoxPro level serves as a default value for subsequent connections.
