Don't pass the dates as strings, use parameters and set the blank date
parameter to null prior to sending it:
PRIVATE myDate AS Date
myDate = DATE()
IF EMPTY(m.myDate)
m.myDate = NULL
ENDIF
m.lcSQL = "INSERT INTO myTable (myDateField) VALUES (?m.myDate)"

I have a SQL Server 2012 Express table with a field called DOB of type DATE
The field accepts NULL values and does not have a default value..
To insert the DOB from VFP I transform it to the form 'YYYY-MM-DD' and send
it as a character string.
However, if the DOB is empty, the only way VFP inserts the record is if the
empty value is sent as ''
and the DOB field displays '1900-01-01' which is the value inserted.
I want to insert NULL in the field, not '1900-01-01'
If I use the SQL Server Management Studio, I can insert the NULL value
directly with this expression:
insert into mydatabase.dbo.employees(name,dob) values( 'John Doe',NULL)
However, this command, from VFP, does not insert the record:
cCmd = [insert into mydatabase.dbo.employees(name,dob) values( 'John
Doe',NULL) ]
sqlexec(nHandle,cCmd)
How can I get the field to get the NULL value?
TIA
