FIX: SQLSetProp() Without Expression Does Not Restore Defaults (145846)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 3.0
  • Microsoft Visual FoxPro for Windows 3.0b
This article was previously published under Q145846

SYMPTOMS

Leaving off the optional [eExpression] in SQLSetProp() may not restore Visual FoxPro defaults for all SQL properties.

WORKAROUND

The values must be set manually, instead of relying on SQLSetProp() to restore the default values.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0 for Windows.

MORE INFORMATION

The help file describes eExpression as "specifies the value for the setting you designate with cSetting. If you omit eExpression, the default value is restored for the setting."

However, the following properties are not restored to their default settings when leaving eExpression off: 
   WaitTime - Resets to zero and default is 100
   Transactions - Gives error message "Property value is out of bounds"
   DispLogin - Gives error message "Property value is out of bounds"
   BatchMode - Resets to false (.F.)

Steps to Reproduce Problem

Type the following commands in the Command Window: 
   x = SQLCONN()                  && You can use any data source.
   ?SQLGetProp(x,"WaitTime")      && Returns 100
   ?SQLSetProp(x,"WaitTime",200)  && Returns 1
   ?SQLGetProp(x,"WaitTime")      && Returns 200
   ?SQLSetProp(x,"WaitTime")      && Returns 1
   ?SQLGetProp(x,"WaitTime")      && Returns 0!
   ?SQLDisConn(x)
The last call to SQLGetProp() returns 0 when the default for WaitTime is 100.
