「いいね」で手動でテーブルから選択しようとしたとき

USE [tableName]
GO

SELECT [ID]
      ,[Name]

  FROM [dbo].[News]
  where News.[Name] like '%'+ 'te' +'%'
GO

結果は 2 行返されます

21  Test 1
22  Test 3

しかし、ストアプロシージャをテストすると

USE [tableName]
GO

DECLARE @return_value int,
        @TotalRecords int

EXEC    @return_value = [dbo].[NewsSelect]
        @Name = NULL,
        @PublishDate = NULL,
        @SearchStringName = N'te',
        @Sort = NULL,
        @Order = NULL,
        @startRowIndex = 0,
        @pageSize = 25,
        @TotalRecords = @TotalRecords OUTPUT

SELECT  @TotalRecords as N'@TotalRecords'

SELECT  'Return Value' = @return_value

GO

0 を返します どこに問題がありますか? なぜ2行を返さないのですか?

問題が見つかりました

 @SearchStringName nchar(100)=null

タイプをncharからnvarcharに変更すると、問題なく動作します:)

@TotalRecords を設定します

SELECT  @TotalRecords as N'@TotalRecords'

ただし、@return_value を使用します

SELECT  'Return Value' = @return_value

おそらくあなたが意味したのですか？

 SELECT  'Return Value' = @TotalRecords
