This kind of string concatenations are open for SQL Injection attacks. Also _date column should be some date/time type instead of character IMO:. And use using statement to dispose your connections and commands. –Soner Gönül Sep 3 '15 at 7:18 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted Try to use this i.e., remove the *, it is not required with DELETE statement: string sql = "DELETE FROM [" + tablename + "$] where _date = '" + full_date + "'"; Also the value which you are getting in full_date doesnt seem to be in correct format. Do check the value which you are getting in full_date with the format in which you are having in your table. On a side note: You code is prone to SQL Injection. You need to use prepared statement to avoid that. share|improve this

I'm pretty sure it's a stupid mistake of me but can't figure it out. thank you in advance. alex.alekan 6 posts since Oct 2014 Community Member c# 0 Shark_1 86 1 Year Ago Suppose, your problem is syntax error missing in ConnectionString. Your ConnectionString should be conn.ConnectionString = Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\alm1.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES;IMEX=1"; To know more, go here, if you like. 0 Discussion Starter alex.alekan 1 Year Ago thank you for your reply but it didn't work. infact i thing my connectionstring is ok 0 Shark_1 86 1 Year Ago it didn't work Did it perform an exception as you get earlier? Your SQL Query Statement is in wrong format. "SELECT TXT" + "FROM [2$]" What is "TXT"? You tried to concatinate two strings. If "TXT is a Field Name or Column header, a space is needed in between "TXT" and "FROM".After concatination it will transform to "SELECT TXTFROM [2$]". This is a wrong SQL Statement. Your SQL Statement should be Select * From [Sheet Name] 0 Jan-Willem 1 Year Ago This text "SELECT TXT" + "FROM (...)" will resolve to SELECT TXTFROM (...)" As a result of that the FROM keyword will not be found Should read "SELECT TXT " + "FROM (...) " I prefer to add a space to all substrings that are part of a SQL statement. 0 Discussion Starter alex.alekan 1 Year Ago yep it was the space thing ..silly me. Anyway thank you both for your replies helped alot
