    <p>I am newbie in java. I try to make a stored procedure(SP) in SQL SERVER. The SP is: </p> <pre><code>go create procedure sp_calculate @value1 int = 0, @value2 int = 0, @sum int OUTPUT, @multiply int OUTPUT as begin set nocount on set @sum = @value1 + @value2 set @multiply = @value1 * @value2 end </code></pre> <p>I make traint following <a href="https://stackoverflow.com/questions/1947754/getting-the-return-value-from-jdbc-mssql">Getting the Return Value from JDBC MSSQL</a>. So I do it in Java below: </p> <pre><code>public static void main(String[] args) { try (Connection conn = ConnectionUtil.getConnection()) { CallableStatement cst = conn.prepareCall("{ (?, ?) = call sp_calculate ( @value1 =?, @value2=? ) }"); cst.setInt(3, 4);//try some value cst.setInt(4, 10);//try some value cst.registerOutParameter(1, java.sql.Types.INTEGER); cst.registerOutParameter(2, java.sql.Types.INTEGER); cst.executeUpdate(); int sum = cst.getInt(1); int multiply = cst.getInt(2); System.out.println("sum = " + sum + " - product = " + multiply); } catch (SQLException ex) { Logger.getLogger(StoredProcedured.class.getName()).log(Level.SEVERE, null, ex); } } </code></pre> <p>But the result is <code>"com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '{'."</code> Anyone can tell me what error I create?</p> <p>Finally,I work it on out: </p> <pre><code>public static void main(String[] args) { try (Connection conn = ConnectionUtil.getConnection()) { CallableStatement cst = conn.prepareCall("{ call sp_calculate ( ?,?,?,? ) }"); cst.setInt(1, 10);//try some value cst.setInt(2, 4);//try some value cst.registerOutParameter(3, java.sql.Types.INTEGER); cst.registerOutParameter(4, java.sql.Types.INTEGER); cst.executeUpdate(); int sum = cst.getInt(3); int product = cst.getInt(4); System.out.println("sum = " + sum + " - product = " + product); } catch (SQLException ex) { Logger.getLogger(StoredProcedured.class.getName()).log(Level.SEVERE, null, ex); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
