Sql server Swift仅打印我的sql server查询结果的第一个字符

我是Swift和Xcode的新手。我正在尝试使用Swift从SQL Server获取数据。连接成功。 今天我意识到，当我在xcode中运行查询时，xcode只得到整列值的第一个字符。 例如我的查询字符串如下所示：

var ozetquery:String = "SELECT PRO_NAME AS NAME, Sum(PRO_COUNT) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

client = SQLClient.sharedInstance()!
    client.delegate = self
    client.connect(strIP,username: strUName,password: strPass,database: strDBName){ success in
        if success {
            self.client.execute(self.ozetquery) {
                results in
                for table in results as! [[[String:AnyObject]]] {
                    for row in table {
                        for (columnName, value) in row {
                            print("\(columnName) = \(value)")
                            }}}
                self.client.disconnect()
            }}
        else{}
    }

var ozetquery:String = "SELECT PRO_NAME AS NAME, CAST(Sum(PRO_COUNT) AS NVARCHAR(10)) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

PRO_名称为nvarchar（100），在SQL-SERVER中PRO_计数为int

我获取数据的Swift代码如下：

var ozetquery:String = "SELECT PRO_NAME AS NAME, Sum(PRO_COUNT) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

client = SQLClient.sharedInstance()!
    client.delegate = self
    client.connect(strIP,username: strUName,password: strPass,database: strDBName){ success in
        if success {
            self.client.execute(self.ozetquery) {
                results in
                for table in results as! [[[String:AnyObject]]] {
                    for row in table {
                        for (columnName, value) in row {
                            print("\(columnName) = \(value)")
                            }}}
                self.client.disconnect()
            }}
        else{}
    }

var ozetquery:String = "SELECT PRO_NAME AS NAME, CAST(Sum(PRO_COUNT) AS NVARCHAR(10)) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

通常情况下，我的查询结果如下：

var ozetquery:String = "SELECT PRO_NAME AS NAME, Sum(PRO_COUNT) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

client = SQLClient.sharedInstance()!
    client.delegate = self
    client.connect(strIP,username: strUName,password: strPass,database: strDBName){ success in
        if success {
            self.client.execute(self.ozetquery) {
                results in
                for table in results as! [[[String:AnyObject]]] {
                    for row in table {
                        for (columnName, value) in row {
                            print("\(columnName) = \(value)")
                            }}}
                self.client.disconnect()
            }}
        else{}
    }

var ozetquery:String = "SELECT PRO_NAME AS NAME, CAST(Sum(PRO_COUNT) AS NVARCHAR(10)) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

但是，在xcode中，它的打印方式如下：

var ozetquery:String = "SELECT PRO_NAME AS NAME, Sum(PRO_COUNT) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

client = SQLClient.sharedInstance()!
    client.delegate = self
    client.connect(strIP,username: strUName,password: strPass,database: strDBName){ success in
        if success {
            self.client.execute(self.ozetquery) {
                results in
                for table in results as! [[[String:AnyObject]]] {
                    for row in table {
                        for (columnName, value) in row {
                            print("\(columnName) = \(value)")
                            }}}
                self.client.disconnect()
            }}
        else{}
    }

var ozetquery:String = "SELECT PRO_NAME AS NAME, CAST(Sum(PRO_COUNT) AS NVARCHAR(10)) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

如何在xcode中修复此结果？

我通过如下更改SQL查询语句找到了解决方案：

var ozetquery:String = "SELECT PRO_NAME AS NAME, Sum(PRO_COUNT) AS COUNTER FROM PRO_LIST GROUP BY PRO_NAME"

client = SQLClient.sharedInstance()!
    client.delegate = self
    client.connect(strIP,username: strUName,password: strPass,database: strDBName){ success in
        if success {
            self.client.execute(self.ozetquery) {
                results in
                for table in results as! [[[String:AnyObject]]] {
                    for row in table {
                        for (columnName, value) in row {
                            print("\(columnName) = \(value)")
                            }}}
                self.client.disconnect()
            }}
        else{}
    }
