sql-server - Sql Query problems with Case, Replicate and Trim functions

Question

I have some problems in my SQL queries. The table name is debitorders which consists of the following columns:

1. firstname (varchar(50),null)
2. surname (varchar(50),null)
3. accountnumber (varchar(50),null)
4. accounttype (varchar(50),null)
5. bankname (varchar(50),null)
6. branch (varchar(50),null)
7. amount (varchar(50),null)
8. date (date, null)

This is our query so far:

SET @BankName = 'ABSA'
--SET @BankName = 'First National Bank'
SET @QueryResultA = (SELECT CASE @BankName 
                     WHEN 'ABSA' THEN 'ABSA            0040000146162'
                     WHEN 'First National Bank' THEN 'First National B0020000045603'
                     END)
--PRINT @QueryResultA
SET @Amount = (SELECT amount FROM debitorders)
SELECT
       left(LTRIM(RTRIM(firstname)),1) + '' + CONVERT (varchar(15),LTRIM(RTRIM(surname)),1),
       (SELECT left(cast(LTRIM(RTRIM(accountnumber)) as varchar(14))+replicate(' ',14),14) ),
       CASE accounttype 
         WHEN 'cheque' 
            THEN left(cast('CH' as varchar(3))+replicate(' ',3),3) 
         WHEN 'savings' 
            THEN left(cast('SAV' as varchar(3))+replicate(' ',3),3)
         WHEN 'credit card' 
            THEN left(cast('CC' as varchar(3))+replicate(' ',3),3)
         WHEN 'other' 
            THEN left(cast('OTH' as varchar(3))+replicate(' ',3),3)
      END, 
      left(cast(LTRIM(RTRIM(branch)) as varchar(10))+replicate(' ',10),10),   
      REPLICATE('0', 7 - DATALENGTH (REPLACE(amount,'.',''))) + LTRIM(RTRIM(REPLACE(amount,'.',''))),
      REPLACE(CONVERT(VARCHAR, date,103),'/','') AS DebitDate
      --REPLACE(CONVERT(VARCHAR(10), date, 104) AS [DD.YYYY.MM]),'.',''
FROM debitorders
WHERE bankname = @BankName

The result should be:

1. firstname (pad side:n/a, Length:1)
2. surname (pad side:right, Length:15)
3. accountnumber (pad side:right, Length:14)
4. accounttype (pad side:right, Length:3)
5. branch (pad side:right, Length:10)
6. amount (pad side:left, Length:7)
7. date (pad side:n/a, Length:8, setting format to ddyyyymm)

Why aren't the columns recognized?

Answer 1

您是否针对正确的数据库运行查询？您的 debitorders 表是在哪里创建的？

我会说首先检查您是否没有针对主数据库运行查询。

Answer 2

你需要声明你的变量：

DECLARE @BankName VARCHAR(50) = 'ABSA';

您还尝试在 @Amount 变量中设置多条记录。你需要在这里聚合吗？
