salam
i'm trying to make a query and in the condition i'm using "BETWEEN" to get what i want in a specific periode.the start date and the end date are in maskedtextbox (short date)
this is a part of query

C#

where
dd.finance=0
and dd.Date_depot between  '" + Convert.ToDateTime(maskedTextBox1.Text)+" ' and ' " +Convert.ToDateTime(maskedTextBox2.Text)"'
and dd.annule=0
and dd.XTransfertSortant=0

the probleme is when i write the query in this way i got an error that ";" is missed before " and dd.annule=0 "

or erro " newline in constant "
with this code

C#

dd.finance=0
and dd.Date_depot between '"+maskedTextBox1.Text+"' and '"+ maskedTextBox2.Text+"'
and dd.annule=0

Solution 1

In first e.g
where
dd.finance=0
and dd.Date_depot between '" + Convert.ToDateTime(maskedTextBox1.Text)+" ' and ' " +Convert.ToDateTime(maskedTextBox2.Text)+"' //forgot '+' sign
and dd.annule=0
and dd.XTransfertSortant=0

try to use
DateTime.Parse( maskedTextBox1.Text );
to convert string to DateTime

and check the format of the date also
