Question

当我在Laravel框架中连接到MSSQL数据库并从任何表中读取数据时，都会得到以下信息：

“Ü»ñÏ»ñ¨Ý»ñÏ³ÝÛáõÃ»ñ”

我将亚美尼亚文字存储在数据库中。我尝试使用许多不同的字符集，但仍然无法解决我的问题。

我应该使用哪种类型的字符集？

数据存储在varchar中。我正在使用当前配置，用于连接：

'sqlsrv' => [
            'driver' => 'sqlsrv',
            'host' => env('MS_DB_HOST', 'localhost'),
            'port' => env('MS_DB_PORT', '1433'),
            'database' => env('MS_DB_DATABASE', 'forge'),
            'username' => env('MS_DB_USERNAME', 'forge'),
            'password' => env('MS_DB_PASSWORD', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_bin',
            'prefix' => ''
        ],

Table screenshot

select c.name, t.name, c.collation_name from sys.columns c join sys.types t on c.system_type_id = t.system_type_id where object_id = object_id('VMATERIALS')

和

select c.name, t.name, c.collation_name from test.sys.columns c join sys.types t on c.system_type_id = t.system_type_id where object_id = object_id('VMATERIALS')

Query result

在我的MSSQL数据库中，有以下过程：

CREATE FUNCTION asf_ConvertANSIToUnicode (@Source varchar(500)) RETURNS nvarchar(500) AS
BEGIN
DECLARE @Result nvarchar(500)
DECLARE @i bigint
DECLARE @CharCode bigint
DECLARE @Diff bigint
SET @i = 1
SET @Result = ''
While @i <= LEN(@Source)
      Begin
        SET @CharCode = ASCII(SUBSTRING(@Source,@i,1))
        IF @CharCode<128
           SET @CharCode = @CharCode
        ELSE
            IF @CharCode between 178 and 253
                  begin
                        SET @Diff = @CharCode - 178
                        IF @CharCode % 2 = 0
                           SET @CharCode = 1329 + @Diff / 2
                        ELSE
                           SET @CharCode = 1377 + (@Diff-1) / 2
                  END
            ELSE 
                  SET @CharCode = CASE @CharCode
                                        When 162 Then 1415
                                        When 163 Then 1417
                                        When 164 Then 41
                                        When 165 Then 40
                                        When 166 Then 187
                                        When 167 Then 171
                                        When 168 Then 8212
                                        When 169 Then 46
                                        When 170 Then 1373
                                        When 171 Then 44
                                        When 172 Then 45
                                        When 173 Then 1418
                                        When 174 Then 8230
                                        When 175 Then 1372
                                        When 176 Then 1371
                                        When 177 Then 1374
                                        When 254 Then 1370
                                        ELSE @CharCode
                                   END
        SET @Result = @Result + nchar(@CharCode)
        SET  @i = @i + 1
      END 
RETURN @Result
END

和

CREATE FUNCTION asfe_ConvertANSIToUnicode (@Source varchar(500)) RETURNS nvarchar(500) AS
BEGIN
    RETURN dbo.asf_ConvertANSIToUnicode (@Source)
END

如果它可以帮助我，如何在查询中使用它？

任何帮助将不胜感激。

在我的数据库中，我具有将ANSI转换为Unicode的功能：

CREATE FUNCTION asf_ConvertANSIToUnicode (@Source varchar(500)) RETURNS nvarchar(500) AS
BEGIN
DECLARE @Result nvarchar(500)
DECLARE @i bigint
DECLARE @CharCode bigint
DECLARE @Diff bigint
SET @i = 1
SET @Result = ''
While @i <= LEN(@Source)
      Begin
        SET @CharCode = ASCII(SUBSTRING(@Source,@i,1))
        IF @CharCode<128
           SET @CharCode = @CharCode
        ELSE
            IF @CharCode between 178 and 253
                  begin
                        SET @Diff = @CharCode - 178
                        IF @CharCode % 2 = 0
                           SET @CharCode = 1329 + @Diff / 2
                        ELSE
                           SET @CharCode = 1377 + (@Diff-1) / 2
                  END
            ELSE 
                  SET @CharCode = CASE @CharCode
                                        When 162 Then 1415
                                        When 163 Then 1417
                                        When 164 Then 41
                                        When 165 Then 40
                                        When 166 Then 187
                                        When 167 Then 171
                                        When 168 Then 8212
                                        When 169 Then 46
                                        When 170 Then 1373
                                        When 171 Then 44
                                        When 172 Then 45
                                        When 173 Then 1418
                                        When 174 Then 8230
                                        When 175 Then 1372
                                        When 176 Then 1371
                                        When 177 Then 1374
                                        When 254 Then 1370
                                        ELSE @CharCode
                                   END
        SET @Result = @Result + nchar(@CharCode)
        SET  @i = @i + 1
      END 
RETURN @Result
END

所以，我只是使用它，并通过Unicode字符集以这种方式获取数据：

\DB::connection('sqlsrv')->select('SELECT test.dbo.asf_ConvertANSIToUnicode(a.MTNAME) 
    FROM test.dbo.VMATERIALS a;');

在数据库设置中，我使用了以下配置：

'sqlsrv' => [
            'driver' => 'sqlsrv',
            'host' => env('MS_DB_HOST', 'localhost'),
            'port' => env('MS_DB_PORT', '1433'),
            'database' => env('MS_DB_DATABASE', 'forge'),
            'username' => env('MS_DB_USERNAME', 'forge'),
            'password' => env('MS_DB_PASSWORD', ''),
            'charset' => 'utf8',
            'prefix' => '',
        ],

感谢所有人。
