使用Microsoft JDBC驱动程序的SELECT INTO查询影响的行数

Question

Is there a way to get a "rows affected" result for

SELECT * INTO TableB FROM TableA

with Microsoft's JDBC driver for SQL Server? When I execute that query in SQL Server Management Studio it returns the number of rows the same way as it does for DELETE, INSERT, or UPDATE.

I tried executeQuery but it doesn't return a ResultSet . I tried executeUpdate but I always get -1 as result, and I tried execute , but the return value seems to be false so there is no ResultSet . I've downloaded the MS JDBC driver 6.0 from 31.01.2017 because I read about problems with older versions.

Answer 1

Update: This issue has been fixed in version 6.1.5 of the JDBC Driver for SQL Server.

(previous answer)

Testing confirms that even with the most recent Microsoft JDBC driver (6.0.8112.100)

 sql = "SELECT * INTO TableB FROM TableA"; try (Statement st = conn.createStatement()) { int n = st.executeUpdate(sql); System.out.printf("%d row(s) affected", n); } 

produces

 -1 row(s) affected 

while the jTDS driver correctly returns the actual number of rows:

 3 row(s) affected 

A workaround for the Microsoft JDBC driver would be to use an anonymous code block to return a ResultSet containing @@ROWCOUNT

 sql = "SET NOCOUNT ON; " + "SELECT * INTO TableB FROM TableA; " + "SELECT @@ROWCOUNT AS n; "; try ( Statement st = conn.createStatement(); ResultSet rs = st.executeQuery(sql)) { rs.next(); int n = rs.getInt(1); System.out.printf("%d row(s) affected", n); } 

which does correctly return

 3 row(s) affected
