i try with string split from sql 2016 but he had on another line the values not the same.
how can i do it?

Answer 1

You can try below -
DEMO
select
left(colname,charindex('/',colname)-1) as signon,
right(colname,charindex('/',colname)-1) as signoff
from tablename
OUTPUT:
signon signoff
01-05-2015 20-04-2016

Answer 2

You can use string functions:
select col1,
left(col1, charindex('/', col1) - 1),
stuff(col1, 1, charindex('/', col1) + 1, '')
from t;

Answer 3

You can try the following query.
select substring([SIGN ON SIGN OFF],1,charindex('/',[SIGN ON SIGN OFF])-2) as sign_in,
substring([SIGN ON SIGN OFF],charindex('/',[SIGN ON SIGN OFF])+1,len([SIGN ON SIGN OFF])) as sign_off

Answer 4

if i enter manually both answers worked. but for some reason executing was give me an error. so i give up from trying in the Sql code i did in c#.
here my solution that worked fo all cells.
DBHelper.DBHelper da = new DBHelper.DBHelper();
DataTable dt = new DataTable();
dt = da.getAllEmbarques();
foreach (DataRow row in dt.Rows)
{
try
{
List<SqlParameter> p = new List<SqlParameter>();
string nospaces = row[5].ToString().Replace(" ", string.Empty);
string[] newsplit = nospaces.Split('/');
if (newsplit.Count() == 1)
{
string[] newsplit1 = newsplit[0].ToString().Split('-');
DateTime dt1 = new DateTime(Int32.Parse(newsplit1[0]), Int32.Parse(newsplit1[1]), Int32.Parse(newsplit1[2]));
SqlParameter parameter = new SqlParameter("#SIGNIN",SqlDbType.DateTime);
parameter.IsNullable = true;
parameter.Value = dt1;
p.Add(parameter);
parameter = new SqlParameter("#SIGNOFF", SqlDbType.DateTime);
parameter.IsNullable = true;
parameter.Value = DBNull.Value;
p.Add(parameter);
p.Add(new SqlParameter("#id", row[7].ToString()));
da.UpdateStringsplitEmbarques(p.ToArray());
}
else
if (newsplit.Count() == 2)
{
string[] newsplit1 = newsplit[0].ToString().Split('-');
string[] newsplit2 = newsplit[1].ToString().Split('-');
DateTime dt1 = new DateTime(Int32.Parse(newsplit1[0]), Int32.Parse(newsplit1[1]), Int32.Parse(newsplit1[2]));
DateTime dt2 = new DateTime(Int32.Parse(newsplit2[0]), Int32.Parse(newsplit2[1]), Int32.Parse(newsplit2[2]));
SqlParameter parameter = new SqlParameter("#SIGNIN", SqlDbType.DateTime);
parameter.IsNullable = true;
parameter.Value = dt1;
p.Add(parameter);
parameter = new SqlParameter("#SIGNOFF", SqlDbType.DateTime);
parameter.IsNullable = true;
parameter.Value = dt2;
p.Add(parameter);
p.Add(new SqlParameter("#id", row[7].ToString()));
da.UpdateStringsplitEmbarques(p.ToArray());
}
}
catch
{
}
}
thanks you all for the time spending answering my question.
