[英]Retrieve query execution plan text from a MSSQL server using JDBC
I have the following Java method that is only returning the statement itself. 我有以下仅返回语句本身的Java方法。 How can I retrieve the MSSQL query execution plan text using JDBC?
如何使用JDBC检索MSSQL查询执行计划文本?
public String explainStatementMssql(String sqlStatement) {
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
StringBuilder output = new StringBuilder();
try {
connection = Utilities.getConnection();
connection.setAutoCommit(false);
statement = connection.createStatement();
statement.execute("SET SHOWPLAN_TEXT ON");
statement.executeQuery(sqlStatement);
rs = statement.getResultSet();
while (rs.next()) {
output.append(rs.getString(1)).append("\n");
}
statement.execute("SET SHOWPLAN_TEXT OFF");
connection.commit();
}
catch (Exception e) {
e.printStackTrace();
}
finally {
Utilities.close(rs, statement, connection);
}
return output.toString();
}

Have you had a look at the first example in the following post: Get the query plan using jdbc PreparedStatement on sql server 您是否看过以下文章中的第一个示例: 在SQL Server上使用jdbc PreparedStatement获取查询计划
It's not using jtds, but I'm sure minor tweaks should provide you with what you're looking for. 它没有使用jtds,但是我敢肯定,较小的调整应该可以为您提供所需的内容。
