where-in

I am working on a query page where a user selects a value which represents different types, each identified by an ID. The problem is selecting these IDs from the data base using the WHERE IN method. This is my SQL statement SELECT M.REG_NO, T.TYPE_ID FROM MAIN AS M INNER JOIN CLASSIFICATION AS C ON M.REG_NO = C.REG_NO INNER JOIN TYPE AS T ON T.TYPE_ID = C.TYPE_ID WHERE T.TYPE_ID IN (@Types) it will work for one single value, eg. 46, but NOT if the value is in brackets, eg. (46) or ('46'), the way it should be for the IN. I am using visual studio which is auto generating the method to access

This question already has answers here : Closed 4 years ago .

I am using Dapper on ODBC provider, which as known does not support named parameters. For most of my queries I used pseudo named parameters: ?name? . However, when I try to string query = $"select * from \"{TableName}\" where ID in ?Ids?"; return connection.Query<CdfGroupByCdfUserRecord>(query, new {Ids = ids}).ToArray(); I see that Dapper generates query select * from "MY_TABLE" where ID in (?Ids1,?Ids2,?Ids3,?Ids4,?Ids5)? What should I do to get it work? This appears to be a bug in dapper. I'll try to fix it for 1.50.2. I've logged it (for tracking purposes) here 来源： https://stackoverflow

I am working on a join query in which I have to get the data from a column which contain the comma separated values.like allowed_activity contain 1,2,3,4,5,6 this the activity_id which is allowed.

I want to retrieve data from the table based on a couple of columns, some with data, other with NULL. In the first code example below, the procedure is fine - all the rows are returned. In the second example no rows are returned - because NULL=NULL return FALSE. The third example is more or less what I have in mind, when the column has NULL values, then this clause has to be "ignored" and only the data in the first two columns are used to return the rows based on these two columns. SELECT * FROM XYZ WHERE col1 IN ('a', 'b') AND col2 IN ('c', 'd') AND col3 IN ('e', 'f') SELECT * FROM XYZ WHERE
