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?

Thank you. It works well as you suggested but:
cName = 'RAFAEL' vDOB = NULL
cCmd = 'insert into mydatabase.dbo.employees(name,dob) values (?cName,?vDOB)' sqlexec(nHandle,cCmd)
the above works, the below construct does not:
Text to cCmd textmerge noshow flags 2 pretext 15
insert into mydatabase.dbo.employees(name,dob) values ('<<cName>>',<<vDOB>>)
endtext
sqlexec(nHandle,cCmd)
Why?
I use text.. endtext most of the time, especially when the statements are very long and occupy several lines.
Character strings are surrounded with '<<>>', numbers are <<>> and dates are '<<cDate>>' (dates are converted to the form YYY-MM-DD)

I use TEXT ENDTEXT all the time too, but I moved away from the string substitution provided by <<>>.
I would imagine it is failing because you need single quotes around the <<vDOB>> like this:
Text to cCmd textmerge noshow flags 2 pretext 15
insert into mydatabase.dbo.employees(name,dob) values ('<<cName>>','<<vDOB>>')
endtext
This is how I would do it:
cName = 'RAFAEL' vDOB = NULL
Text to cCmd textmerge noshow flags 2 pretext 15
insert into mydatabase.dbo.employees(name,dob) values (?cName,?vDOB)
endtext
sqlexec(nHandle,cCmd)

NULL means "I don't know" and <<NULL>> in a textmerge returns nothing.
In my VFP 9, it returned .NULL. as the second argument, which no server would understand :)
try:
SET NULLDISPLAY TO 'NULL'
before the textmerge.
Also, this might work better if you formatted the date you are inserting using DTOS and wrapped it in single quotes.

myDate = createObject("Date") myDate.value = date() ? myDate.ToString() && 06/14/2018 ? myDate.ToString('F') && June 14, 2018 00:00:00 AM ? myDate.ToString('D') && Thursday, June 14, 2018 (etc etc etc)

I don't ever remember writing code like this in FP/VFP: myDate = createObject("Date")
That is great that you can, and I bet it would have been easier to pass a date to another language in a function.

myDate = createObject("Date") myDate.value = date() ? myDate.ToString() && 06/14/2018 ? myDate.ToString('F') && June 14, 2018 00:00:00 AM ? myDate.ToString('D') && Thursday, June 14, 2018 (etc etc etc)

Too bad that a Date variable doesn't know enough about itself to present that.
myDateString= myDate.ToString(myFormat)
now iterate through all of the formats to potentially see:
// Displays the following output by format:// d: 6/15/2008// D: Sunday, June 15, 2008// f: Sunday, June 15, 2008 9:15 PM// F: Sunday, June 15, 2008 9:15:07 PM// g: 6/15/2008 9:15 PM// G: 6/15/2008 9:15:07 PM// m: June 15// o: 2008-06-15T21:15:07.0000000// R: Sun, 15 Jun 2008 21:15:07 GMT// s: 2008-06-15T21:15:07// t: 9:15 PM// T: 9:15:07 PM// u: 2008-06-15 21:15:07Z// U: Monday, June 16, 2008 4:15:07 AM// y: June, 2008

NULL means "I don't know" and <<NULL>> in a textmerge returns nothing.
In my VFP 9, it returned .NULL. as the second argument, which no server would understand :)
try:
SET NULLDISPLAY TO 'NULL'
before the textmerge.
Also, this might work better if you formatted the date you are
inserting
using DTOS and wrapped it in single quotes.

Thank you. It works well as you suggested but:
cName = 'RAFAEL' vDOB = NULL
cCmd = 'insert into mydatabase.dbo.employees(name,dob) values (?cName,?vDOB)' sqlexec(nHandle,cCmd)
the above works, the below construct does not:
Text to cCmd textmerge noshow flags 2 pretext 15
insert into mydatabase.dbo.employees(name,dob) values ('<<cName>>',<<vDOB>>)
endtext
sqlexec(nHandle,cCmd)
Why?
I use text.. endtext most of the time, especially when the statements are very long and occupy several lines.
Character strings are surrounded with '<<>>', numbers are <<>> and dates are '<<cDate>>' (dates are converted to the form YYY-MM-DD)

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 = NULLENDIF
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?

Very nice! Adapter Pattern to the rescue :D

In SSMS run this script CREATE PROCEDURE newEmployee -- Add the parameters for the stored procedure here @name varchar(75) , @dob datetime = null AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
Insert into Employees values(@name, @dob)
END GO
In your VP app:
cCmd = [exec newEmployee 'john Doe' ]
sqlexec(nHandle,cCmd)
From wherever you can do this
select * from Employees
You should see this:
name dob john Doe NULL
To get the date in use this statement: exec newEmployee 'Tommy Doe', '1997-01-05'
You will now see this: name dob john Doe NULL Tommy Doe 1997-01-05 00:00:00.000
Let SQL do the work for you and just call that code for all your necessary functionality in the future.
