Question

In this code:

string sql = "SELECT * FROM rd_main WHERE manifest!=\"\" AND manifest IS NOT NULL";
string tableName = "rd_main";
conn.Open();
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
DataSet ds = new DataSet();
da.Fill(ds, tableName);

I keep getting:

Cannot use empty object or column names. Use a single space if necessary.

on the da.Fill(…)

I have tried:

SELECT rd_main.* FROM rd_main WHERE rd_main.manifest<>"" AND rd_main.manifest IS NOT NULL

What am I doing wrong?

Answer 1

You want single quotes, not double quotes.

string sql = "SELECT * FROM rd_main WHERE manifest!='' AND manifest IS NOT NULL";
