Question

我有一个表A，其中包含列“ ColumnName”（它将包含逗号分隔的整数值），并且我有一个存储过程，该过程采用的参数也是逗号分隔的整数值。例如，我在表“ 101,102,103”和“ 103,104,105”中有值，并且用户输入为“ 101,104”，它应该返回2条记录。我该如何实现？需要SQL语句

Answer 1

如果您需要帮助，说明，请告诉我：）

DECLARE 
    @input  VARCHAR(MAX) = '101,104', 
    @separator CHAR(1) =',',
    @separatorPosition INT,
    @value VARCHAR(MAX),
    @start INT = 1

DECLARE @split_input TABLE(Value VARCHAR(MAX))
DECLARE @tmp TABLE (st VARCHAR(50))

INSERT INTO @tmp VALUES ('101,102,103')
INSERT INTO @tmp VALUES ('103,104,105')
INSERT INTO @tmp VALUES ('106,107,108')

SET @separatorPosition = CHARINDEX(@separator, @input)


 IF @separatorPosition = 0
 BEGIN
     INSERT INTO @split_input
     VALUES
     (
         @input
     )
     RETURN
 END

 SET @input = @input + @separator

 WHILE @separatorPosition > 0
 BEGIN
     SET @value = SUBSTRING(@input, @start, @separatorPosition - @start)

     IF (@value <> '')
         INSERT INTO @split_input
         VALUES
         (
             @value
         )

     SET @start = @separatorPosition + 1
     SET @separatorPosition = CHARINDEX(@separator, @input, @start)
 END


 SELECT tmp.st FROM @tmp AS tmp INNER JOIN @split_input AS split ON tmp.st LIKE '%' + split.Value + '%'

SET ANSI_NULLS ON
 GO
 SET QUOTED_IDENTIFIER ON
 GO

CREATE FUNCTION [dbo].[fnParseArray] (@Array VARCHAR(MAX),@separator CHAR(1))

RETURNS @T Table (col1 varchar(50))

AS 

BEGIN

-- @Array is the array we wish to parse

 -- @Separator is the separator charactor such as a comma

  DECLARE @separator_position INT -- This is used to locate each separator character

  DECLARE @array_value VARCHAR(MAX) -- this holds each array value as it is returned

 -- For my loop to work I need an extra separator at the end. I always look to the

  -- left of the separator character for each array value



  SET @array = @array + @separator



 -- Loop through the string searching for separtor characters

  WHILE PATINDEX('%' + @separator + '%', @array) <> 0 

  BEGIN

-- patindex matches the a pattern against a string

SELECT @separator_position = PATINDEX('%' + @separator + '%',@array)

SELECT @array_value = LEFT(@array, @separator_position - 1)

-- This is where you process the values passed.

INSERT into @T VALUES (@array_value)    

-- Replace this select statement with your processing

-- @array_value holds the value of this element of the array

-- This replaces what we just processed with and empty string

SELECT @array = STUFF(@array, 1, @separator_position, '')

END

RETURN 

 END


select * from [dbo].[fnParseArray]('a,b,c,d',',')

这应该做到：

val accessLog = Logging(system.eventStream, "access_log")

val routes =
  path("ping" ) {
    withLog(accessLog) {
      logRequest("ping", Logging.InfoLevel) {
        complete("pong")
      }
    }
  }

您可以像这样测试存储过程：

val loggingAdapter : LoggingAdapter = new LoggingAdapter {
      override def isDebugEnabled : Boolean = logger.isDebugEnabled
      override def isErrorEnabled : Boolean = logger.isErrorEnabled
      override def isInfoEnabled : Boolean = logger.isInfoEnabled
      override def isWarningEnabled : Boolean = logger.isWarnEnabled

      override def notifyDebug(message: String): Unit = logger.debug(message)

      override protected def notifyError(message: String): Unit =  logger.error(message)

      override protected def notifyError(cause: Throwable, message: String): Unit = logger.error(message, cause)

      override protected def notifyWarning(message: String): Unit = logger.warn(message)

      override protected def notifyInfo(message: String): Unit = logger.info(message)
    }

    val routes =
      path("ping" ) {
        withLog(loggingAdapter) {
          logRequest("**ping**", Logging.InfoLevel) {
            complete("pong")
          }
        }
      }
