SQL将字符串中的int替换为文本

我正在尝试进行查询，但在结果中有一列的数字为“2”，我想用“factura”替换

我该怎么做？？我要替换Cust。[文档类型]列

   SELECT Detail.[Entry No_],
           'Cliente' AS Tipo,
           Cust.[Customer No_] AS Cliente,
           Detail.[Posting Date] AS DATA,
           Detail.[Document No_] AS Documento,
           Detail.[Amount (LCY)] AS Valor,
           Cust.[Document Type] AS LiqPorTipo,
           Cust.[Document No_] AS LiqPorNDocumento,
           '97' AS Conta,
           'MR' AS Loja,
           'SUPER' AS Utilizador,
           'MR01' AS POS
    FROM dbo.MBS_tabela_21Detailed_NAV16 AS Detail
    INNER JOIN dbo.MBS_tabela_21_NAV16 AS Cust ON Detail.[Cust_ Ledger Entry No_] = Cust.[Entry No_]
    INNER JOIN dbo.Integracao_Periodo_NAV16 AS Integr ON YEAR(Detail.[Posting Date]) = Integr.Ano
    AND MONTH(Detail.[Posting Date]) = Integr.Mes
    WHERE (Detail.[Document No_] LIKE '%REC%'
           OR Detail.[Document No_] LIKE '%L%')
      AND (Detail.[Entry Type] = 2)
      AND (Cust.[Global Dimension 1 Code] = 'LMR')

这导致

我想要一个

您的查询缺少“详细信息。[条目类型]列”。比较预期的查询结果和您的查询结果，我假设您希望使用case或创建dictionary表来联接它

最好的选择是创建额外的表并将所有键值转换存储在那个里

所以你本来可以 2-事实

并将其加入到您的查询中

如果不是，您应该这样做：

 SELECT Detail.[Entry No_],
           'Cliente' AS Tipo,
           Cust.[Customer No_] AS Cliente,
           Detail.[Posting Date] AS DATA,
           Detail.[Document No_] AS Documento,
           Detail.[Amount (LCY)] AS Valor,
           case when Cust.[Document Type] = 2 then 'factura' else '' end  AS LiqPorTipo,
           Cust.[Document No_] AS LiqPorNDocumento,
           '97' AS Conta,
           'MR' AS Loja,
           'SUPER' AS Utilizador,
           'MR01' AS POS
    FROM dbo.MBS_tabela_21Detailed_NAV16 AS Detail
    INNER JOIN dbo.MBS_tabela_21_NAV16 AS Cust ON Detail.[Cust_ Ledger Entry No_] = Cust.[Entry No_]
    INNER JOIN dbo.Integracao_Periodo_NAV16 AS Integr ON YEAR(Detail.[Posting Date]) = Integr.Ano
    AND MONTH(Detail.[Posting Date]) = Integr.Mes
    WHERE (Detail.[Document No_] LIKE '%REC%'
           OR Detail.[Document No_] LIKE '%L%')
      AND (Detail.[Entry Type] = 2)
      AND (Cust.[Global Dimension 1 Code] = 'LMR')

因为您要根据联接结果替换一个柱基。贝娄可能会帮助你

UPDATE
    Table_A
SET
    Table_A.col1 = Table_B.col1,
    Table_A.col2 = Table_B.col2
FROM
    Some_Table AS Table_A
    INNER JOIN Other_Table AS Table_B
        ON Table_A.id = Table_B.id
WHERE
    Table_A.col3 = 'cool'

基于上述结构，您的sql scritp如下所示

UPDATE Detail
SET Detail.[Entry Type] = REPLACE(Detail.[Entry Type], '2', 'factura')

FROM dbo.MBS_tabela_21Detailed_NAV16 AS Detail
INNER JOIN dbo.MBS_tabela_21_NAV16 AS Cust
  ON Detail.[Cust_ Ledger Entry No_] = Cust.[Entry No_]
INNER JOIN dbo.Integracao_Periodo_NAV16 AS Integr
  ON YEAR(Detail.[Posting Date]) = Integr.Ano
  AND MONTH(Detail.[Posting Date]) = Integr.Mes

WHERE (Detail.[Document No_] LIKE '%REC%'
OR Detail.[Document No_] LIKE '%L%')
AND (Detail.[Entry Type] = 2)
AND (Cust.[Global Dimension 1 Code] = 'LMR')

这是无效的标准SQL。您使用的是哪种DBMS产品？您使用的是哪种sql平台？返回的错误消息（如果有）是什么？FROM子句中的错误：“SELECT”附近。无法分析查询文本。您使用哪台SQL server？SQL server 2016假定数据类型不是

INT

。加入后，您具有值并且知道目标列类型，因此可以强制转换它。这不起作用。。。无法更新列或表达式“文档类型”。此SQL语句类型不能在视图或函数中使用。只能使用SELECT语句。我将Cust的更新表和Set字段更改为Cust。[文档类型]您的文档类型是什么？要在此列中存储的数据类型。请检查希望类型是否不匹配
